Color shift (gamma?) between XDCAM Ex and PROres

Hi,
We have edited a show in Apple XDCAM EX in 23,98 HD. We did a QT movie of that sequence into the native codec that we edit with (Apple XDCAM EX).
Into quicktime, or even in compressor, we re-export ta video into Apple Pro Res and we are experiencing a big color shift between both codec.
Somedoby have an idea on that?
Thank you!
Nicolas

There's a know shift in the gamut between the two recording methods because of the compression scheme.
If you search the posts here and on the Cow, you'll find other references to it.
You might want to consider working in ProRes all the way through. It's a good way to even out all the differences between source footage and act as a neutral Digital Intermediary. The nice thing is that it's tuned to run on the machines and runs very efficiently. It's been a big help here when I've had mixed footage, or have to go out to all the different formats and uses that I do. I get no shifting at all, even between proxy and HQ. So I can do all my editing and effects in lightweight proxy and then conform to the more space demanding 422 or HQ.

  • Color correction problem between original sequence and multicam sequence... Please help

    I used three camcorders to record a youth dance recital.  I created an orginal sequence for the three camcorders and another sequence using the multicam feature to edit the dances.  After I finished editing, I went back to the original sequence to make some color correction and brightness adjustments using the Fast Color Correction controls.  After that, I sent everything to Encore to create a DVD.  When I watched the DVD, I noticed some of my color correction settings were still off, so I went back to the orginal sequence to make some changes.  Unfortunately, the multicam sequence would not read the new settings.  After a few unsuccessful attempts to get the clip from the multicam sequence to read the clip from the original sequence, I decided to start over by clearing the Fast Color Correction controls from the clip.  The multicam sequence then adjusted back matching the original sequence.  However, when I started a new Fast Color Correction control in the original sequence, the multicam sequence would not take the new settings.  How to I get the mulitcam sequence to read the orginal sequence?

    Thank Jim for replying:
    I am stumped on this one.  I did a few radical tweeks and it did not take.  For example, I made one clip in the original sequence go completely dark.  However, the clip in the mulicam sequence did not change.
    I even deleted the render files and the work area render files and started over with making changes.  Nothing.  Any change I make on the original sequence will no longer adjust in the multicam sequence.
    Any last words of advice before I delete the entire multicam sequence and start over?  Thanks.

  • Color shift between image viewed in ACR and open in PS

    Today I updated Photoshop CC and now I have a slight color shift problem between the same image open in ACR and then opened in Photoshop. It appears to be slightly more saturated in ACR.
    I have tried the same thing on another computer and it does NOT have the same problem so it must have been something that happened in the update (ACR was one of the items updated). I have also compared the preferences between the two computers and they are identical.
    I guess the next thing to do is to deinstall PS and reinstall????
    Any advice would be appreciated.

    Any difference between ACR and Photoshop is most likely due to a monitor profile problem. They both use the same monitor profile, but there are differences in the actual conversion so a problem can show up differently between them.
    Is your monitor calibrated/profiled, and if so how, using what calibrator? Or are you using the Windows default (sRGB), or perhaps you got a bad manufacturer profile through Windows Update? (yes, that happens frequently).
    To find out if the monitor profile is indeed the problem, go to Control Panel > Color Management > Devices. Set sRGB IEC61966-2.1 as default profile (if it isn't already), then relaunch Photoshop/Bridge and see if the difference is still there. If your monitor is wide gamut, use Adobe RGB instead.
    Note that this doesn't fix the problem as such, but if you don't have a calibrator sRGB will usually be close enough until you decide to get one.
    If you do have and use a calibrator, make sure it is set to make v2 profiles, not v4, and matrix rather than LUT profiles.

  • Camera profiles and Highlight Recovery: color shifts

    I often see significant hue shifts and loss of saturation when using the Recovery slider in conjunction with the new dng camera profiles. I don't remember to ever have this 'problem' with legacy ACR profiles. In the sample below, you can see just that:
    Sample: http://farm4.static.flickr.com/3224/2918603614_7a562db832_o.png
    This becomes a bit of a problem, as recovering highlights now brings color shifts as a side-effect and you have to go fiddling with color controls.
    Often, the new, 'shifted' colors are even more pleasing than the 'unshifted' (i.e. recovery set to zero), but this is a psychological and a workflow problem too. It is just not nice to know that controls are interdependent and have side-effects.
    Is it a bug or a fact of life? What's so different about the old a new profiles, that cause this difference in recovery effect?
    The DNG to play: http://www.yousendit.com/download/bVlBblFOR0Y3N0JFQlE9PQ

    Eric, thanks a lot for the explanation and technical details.
    Knowing this helps me a bit, as it confirms my observations. What is not clear, is how these shifts will/should (or would they?) be addressed?
    I mean Recovery was a perfect control until now. it just did what is should, reliably and consistently. Now we have the side-effect of color shifts.
    a) Will Adobe adjust the algorithm to fit the new profile system? A bad thing, because it will not assure backward compatibility.
    b) Will Adobe add a new control? Worse, because it adds unnecessary complexity.
    c) Will/could the profiles be modified in a way as these color shift don't happen. As I understand from your previous post, this doesn't seem possible.
    d) Will it just be left as is and I'll have to live with the color shifts? Now it seems it's the most likely option. Sad, because Recovery used to be so powerful, and now its power is somewhat compromised.

  • Same colors display differently between Illustrator and Photoshop

    Hi there,
    I would love to know why the same colors display differently between my Photoshop and Illustrator apps (CS3). For example, a logo will display much darker or more vividly in Illustrator than in Photoshop, same file, same colour values. My color settings are synchronized from Adobe Bridge to North American Pre Press 2. I've opened the logo file in RGB color mode, in both apps. It would be so helpful if both apps displayed the colours consistently.
    Any suggestions on how to do this would be wonderful!
    Thanks!
    Bobbie

    Hello Bobbie,
    I am using CS3 too and let me tell you that this Illustrator version is the worst ever. You best bet is to take the "Eye Drop" tool and select the Photoshop element to match the color.
    CS4 also have problems when handle placed items. Sadly I can tell you that CS2 is more reliable than CS3 and CS4.
    Not even if you use Pantone colors will match, Illustrator will change the colors making it impossible to match. "Adobe Quality"

  • How do I prevent the Darker Shade Box (color shift) around Vector Objects when Printing

    Sorry in advance for the novelette. I am absolutely mystified and frustrated and would love some help! I've been working on this problem for about 30 hours over the last 4 days to figure out what the heck is happening and cannot find an answer through various forms of research.
    Basically, when I print a JPEG, I am getting this area (a box) of darker shaded coloring around my heart and love text.  I've tested it a million different ways and am at a loss as to what the problem is ... is it an application problem, a color profile problem between my applications and printer, an improper way that I saved my file, etc.
    Here is a photo I took of the image printed out (so it is slightly skewed from camera distortion):
    The details:
    (1) I create graphic art and sell it online. I save all of my printable art as JPEG files because of my customer base (diy hobbyists that print on their home printers without much knowledge base nor graphic design software).
    (2) I use both Adobe Illustrator (AI) and Photoshop Elements 11 (PSE11) to design and save my artwork.
    (3) I insert JPEG images into Microsoft Word 2003 documents to "test print" since most of my customers use home printers to print. Since most people have this basic software, it is a good gauge of the kind of print out they might get using the same or similar software.
    (4) My PSE11 color profile setting is the default sRGB. I have test printed many times and I get the truest colors with this color profile.
    (5) My AI color settings are normally also an sRGB color mode, but on occasion, I use a CMYK color mode if I am creating a larger document that I know the customer will need to take to a professional printer to print out.
    (6) I do my home printing (for proofs) on an Epson Stylus Photo 1400 (which has the 6 color ink cartridges).
    (7) Until this printing problem occurred on this test print out, I always used the "photo enhance" option when I designate settings for my printer via the Microsoft Word documents.
    IMPORTANT: This is when I have the color shift?? or color rendering issues?? and it is the only time. If I use the regular ICM/ICC color profile of sRGB, the printing issue doesn't occur. Instead, I have a solid color background instead of this one with the strips of lighter color on the top and bottom.  However, I can't control how the customer prints, so I need to feel confident that whatever color profile setting they use, they will not run into this problem.  I even test printed the documents over at FedEx and the darker box/color shift did not occur.
    (8) The document in question only has 3 sets of objects: the heart, the solid colored rectangle colored background and the text.  All 3 objects are vectors, they are at 100% opacity and there are no "special effects" applied.
    (9) The image was entirely created in AI this time and exported as a maximum quality JPEG file, although you will see below that I tried many ways to create and save the file so that I didn't have the color band borders on top/bottom.
    (10) I regularly use AI for part of my art, then I drag it to my PSE11 open document and it becomes a Vector Object (it cannot by copying/pasting into a PSE11 document).  I also regularly export AI images as PNG files, then insert them into an open PSE11 document. This printing issue has not occurred until recently.  Here is an example of a very complex AI image I created, then inserted into PSE11 just to add the background (the Teddy Bear and books are AI vector objects) that were exported as PNG files then inserted into PSE11 to integrate with the background image - I test printed with Photo Enhance and had no printing issues:
    So, from the research I have done, it looks like it is a color rendering or color space issue with conflicting color profiles in the same document. I checked my color profile settings and both sRGB and CMYK were set to embed ICC color profiles.
    I tried changing AI settings to Preserve Numbers (ignore linked profiles) for CMYK, but that didn't work.
    I also checked and made sure that not only the document setup showed the sRGB color profile, but that all the objects within the document also were converted to sRGB as well for consistency. That didn't work.
    I tried converting the document to CMYK along with the vector objects. That didn't work.
    I tried saving the heart image as a PNG file alone, the "love" text as a PNG file alone, both the heart and text together as a PNG files alone. Once saved as PNG files, I inserted them into an open empty PSE11 document - as I normally do. I then added the background color I wanted. That didn't work - the print still showed the color changes.
    I tried dragging each vector object separately and even as a group and got the same color change issue when printing.
    I tried "expanding" and "outlining" the text before exporting as JPEG, before exporting as a PNG and before dragging as a vector object into PSE11. Expanding the text did not help the situation.
    I tried exporting as Adobe PDF, then opening in PSE11, then resaving as JPEG. That didn't work.
    I tried flattening transparency (even though there is no transparency in the AI file). That didn't work.
    I tried rasterizing the image. That didn't work.
    Thinking that the file might be corrupt, I started from scratch and redesigned the same heart and love text.  Unfortunately, I had the same problem as before.  At this point, my AI started becoming buggy and would not open new files. It happened repeatedly and I decided it was best to uninstall and reinstall AI (and maybe that would fix the problem).
    I created just the heart in AI, then inserted it into an open PSE11 document (both after exporting as PNG and also by dragging as Vector Object from AI). It seemed to work. I could both drag the vector into PSE11 from AI and export from AI as a PNG, then insert into open PSE11 document with a background color - and it printed a solid background.
    So, I thought that reinstalling and setting back to defaults worked. But, then I added the love text around the heart and tried exporting as JPEG files and the same problem continued to recur. Whether I dragged as a Vector object into PSE11 (the heart object and love text separately and also another time with the vector objects dragged as a group) or saved them as PNG files and inserted into PSE11 - I got the different shades of color on what should be a solid background. I even tried saving the PSE11 as a PSD file first, then resaving as JPEG and I tried saving as PNG and printing and this didn't help solve the problem.
    I really think it is some color conflict issue but I can't figure it out. I am definitely not very knowledgeable about color profiles and how to sync all my devices, however, as I mentioned, this was not an issue until recently (and I think??? I recall changing the CMYK setting from Preserve Numbers to embed color profile a month or so ago - however, it should have been solved when AI went back to its defaults upon reinstall).
    The reason I believe it is a color rendering/color space issue is because I could see the color output when I saved the JPEG with CMYK color profile versus sRGB color profile and the sRGB colors were much richer, not surprisingly. The top and bottom colors matched the sRGB printout and the middle darker box section matched the CMYK printout.
    I am sure it is something fundamental or simple and I am completely overlooking it.  I wish it were just a transparency issue, because people know how to fix or do workarounds for it. But, there are no vector objects with any transparency ...
    If I missed some detail, I apologize. Any help would be a dream come true at this point! lol
    Thank you!

    Okay, I got motivated to try again.  From doing a bit more research on troubleshooting AI printing problems, the Adobe article talks about print drivers. It was advised to uninstall and reinstall the print driver if the printing issue persists. So, I did. Unfortunately, I still had the same result after reinstalling and trying a test print! Ugh.
    So, as Jacob said upfront, I seem to have an overactive print driver that is trying too hard (and it is a non-postscript printer which I realize is part of the problem).
    There are so many variables in my situation as to how I create art and save/export art. I sometimes work solely in AI, sometimes solely in PSE and sometimes I use both programs to create. Consequently, I will:
    (1) export directly from AI as JPEG if I am not adding PSE11 artwork.
    (2) export directly from AI as PNG  if I plan on inserting that image into PSE11 to add to artwork I have created in PSE11.
    (3) drag vector objects as a Smart Objects directly from AI to PSE11 to add to artwork I am creating in PSE11 if I know I will playing with the vector object and resizing in PSE11.
    So, I did a test print using scenario 2, where I inserted the heart and love text PNG (AI created vector object) into an old PSE11 document. This old document already had a vector object from AI with a solid background and I knew it printed correctly. So, after inserting this new PNG from AI into this old document, it printed correctly using the photo enhance mode.
    However, I haven't had a chance to actually create new art in the older AI files (that I know print properly), resave as something else and try another test print (either by exporting as JPEG and printing in Word or by exporting as PNG file and inserting into PSE11 document, then saving as JPEG and printing in Word).
    After testing the different possibilities of ICM settings within my printer, I found that the JPEG images printed out with the truest colors and best quality if I simply selected "no color management" from the printer. Shocker, huh? lol
    MY SOLUTION: So, what I think I will simply do is add an instruction sheet with the printables I sell, explaining that the color profile setting should never be handled by the printer so make sure to turn off color management by printer (and if they feel they must use the printer for color management, make sure the setting is sRGB since I embed that color profile in my JPEG's).
    Edited to add: Since my issue was never about how I could print a successful image (I knew I could simply change the color profile settings), but rather about how to make sure that customers would get consistent and high quality print outputs of my digital images, this seems like the best approach.
    I don't think I will every really know exactly why I am now getting color shifts in the "photo enhance" mode when I did not have this problem a couple months ago - applying the same methods of creating artwork. I was concerned that I was saving/exporting using incorrect or mismatched color settings or something of that nature.  However, since I went through the process of making my color spaces the same for everything, and I still have issue, clearly that is not the culprit. The only thing I can do to solve the problem and it is a straightforward solution anyway -> is to educate the buyer on how to print successfully (don't use photo enhance! ha ha).
    Thanks again to everyone who chimed in and offered advice!

  • Third party profiles results in color shifts

    Using LR on a calibrated iMac and printing to an Epson Pro 3800, I'm now getting easily noticeable color ***** in the printed output, when using 3rd party paper profiles (e.g. Hahnemuhle Fine Art Pearl or Pixel Genius Epson Exhibition Fiber profile), but if I specify an Epson profile, the output is a perfect screen match!? I specified the Epson Glossy Photo profile in LR and printed on their new Exhibition Fiber paper, and the print was perfect. Of interest here, is that print Preview showed the color shift with the other profiles and printed the same, which suggests Print Preview is an accurate rendition of the final output to paper (and yes ... no color control was specified in the driver).
    This was not the case prior to the last LR update, as the 3rd party profiles the job accurately!?

    "Also, I've emailed the correct people at Epson regarding the issue with the info sheet inside the paper. From what I know and the discussions I've had with the product manager for the 3800 and the EFP, the info sheet is WRONG. But, due to the holidays, I don't expect a response till mid-week next week. "
    I'd be curious to hear back what the response is. I hate ambiguities. There is one other thing that is bothering me about your theory, and that is I just came back from mounting an exhibit of my photos, printed using LR specifying the HFA3800FineArePearlPK.icc profile printing to their Fine Art Pearl paper. The results on paper matches the current LR screen images. This I did I think prior to applying 1.3.1 (a few weeks past). Those images in LR look the same to me, yet the profiles are now visibly altering the tonality. I will re-calibrate, but my confidence level is in the sewer.
    btw I'd love to see what PS does with the profile, but I can't install CS3 trial. It says CS3 is already installed, but it isn't.
    "System check: Adobe Photoshop CS3 cannot be installed because it conflicts with:
    Adobe Photoshop CS3"
    I had installed it a while back, but it got uninstalled along the way. Any tips around this. My gut feeling is CS3 won't have any problems with the profiles.

  • Color shift during export

    I have just completed a project in Final Cut and I'm now ready to export to DVD Studio and I tried "Export to Quicktime Movie" but the overall colors became brighter. I've done plenty of color correction and I have my monitors calibrated and I see a BIG diference in brightness level.
    What is the most accurate way of getting this project directly to DVD format or HD DVD format without any color shifts or further adjustments? And converting the audio to AC3.
    The project is all in HDV 720p24 from a JVC HD101 camera.
    The length is 15 min 15 sec 19 frms
    I plan to put this on a SD DVD and make a HD DVD image ready so I can burn once I've bought a HD burner.
    Thanks

    Now I opened the same file in FCP and the colors are as the original ones, this must be because there's a diference in color spaces.
    Most people won't be watching this on FCP but other players like quicktime or windows media player and I would not like them to see this shift in colors.
    And what about DVD players?
    If I drop this clip into DVD Studio Pro and see that the colors are like the original (though I still need to go through compression) will the colors remain the same when I use my Apple DVD Player and not shift like quicktime does?

  • Significant color shift between FCP and COLOR?

    Hi there,
    I get a significant color shift when sending footage - either adjusted or unadjusted/unmodified - from FCP to COLOR.
    Before anyone asks, the color shift is visible both internally or on an external broadcast preview monitor.
    From within COLOR, I 'send' back to FCP this sequence - which is still without any form of adjustment (apart from being sent to COLOR), the apparent color shift is now visible/added to the imported sequence (from Color).
    I've tried this on three separate Macs:
    1. The Mac above (6.0.6). (Leopard)
    2. A Mac with the same version of FCP as above. (Snow Leopard)
    3. FCP and on a third Mac with an earlier version of FCP. (Leopard)
    Does everyone have the same problem?
    If not, does anyone have a solution?
    Cheers,
    Dan
    PS: I've tried:
    FCP > Color ProRes contrast shift
    http://discussions.apple.com/thread.jspa?threadID=2150962&tstart=75

    I had the same problem except that I am using version 1 of color and Final Cut Pro 6. I isolated just the video and double checked that I had no filters or if I did I turned them off. I had a smooth cam filter on one shot, but that didn't effect it. I was then able to send it to color without issue, once I had no sound or filters or transitions messing up the pass between final cut and color. Try doing the same, just duplicate or copy your timeline to a new timeline. I would have rendered your footage out to ProRes however as using the DVC Pro codec is probably not ideal. Color also only works with actual full raster files, not so good going from HDV or DVC Pro as they have an anamorphic frame size. This may be causing issues also.

  • Big Color Shift between exported H264 mp4 and Program Monitor

    I get a big Color Shift between exported H264 mp4 on Vimeo/Youtube and Quicktime X and Program Monitor.
    There are quite a few posts on Quicktime gamma issues, but there seem to be no solutions and the other editors I know don't seem to have this problem.
    I know there will be a bit of a shift but this is MASSIVE. At the moment I add a whole extra adjustment layer to all my clips to get it approximately right, but ofcourse this does not solve the issue nor does it give proper results.
    Please do not reply with the "You need a real reference monitor via SDI etc etc ..."
    By my logic on the same screen the program monitor should resemble what is going to be the final result in a relevant player like Quicktime X which all normal apple consumers use to watch their films.  I know VLC and Mpeg streamclip gives different results, but mostly when playing Quicktime/h264 files Quicktime will play it thus average users ( the people I'd like to downwload/buy my films )will watch it in Quicktime.
    Furthermore, Quicktime X's gamma/color looks very similar to the image I get on Youtube or Vimeo - which is where all my current work is going. I'm not outputting to boradcast or DVD etc.
    Strangely enough the MPEG 2 stuff I've done for DVD matches the Youtube output with the Program monitor.
    What am I doing wrong?
    I have a Dell 2711 wide Gamut Display which is calibrated with an SPyder 3 Elite using its full colour gamut ( close to 90% of Adobe RGB - thus bigger than sRGB or Rec709) Could Premiere be ignoring the calibration in the Program monitor and making the image values 16-235 and then Quicktime uses all  values 0-255? If so, how can I fix this?
    Any help will be much appreciated!

    I know this has been a while so hopefully you found some help by now, but maybe this will help anyone stumbling across this.
    What people seem to be missing in what you are asking is... this is the same file, on the same monitor, but with a different appearance in different software.  It is not a question of whether the overall monitoring is GOOD, and it is not a matter of hardware settings (as that would most likely propogate across all software) it is that it is not CONSISTENT side by side on the very same monitor.
    I had very similar issues that really seemed to get worse when we got new monitors, which is what lead me to chime in here.  The monitors were also wide gamut displays.
    The problem is likely this...
    1. The difference being shown are the difference between software that properly color manages (i.e. Premier or After Effects) and software that does not (i.e. Quicktime or some web browsers)
    2. The reason it is so severe is that the wide gamut monitors are able to show many more colors and thus the difference between the managed and unmanaged software is much more exagerrated than on regular gamut monitors.
    I found this great link that helped calm my nerves and helped me get handle on much of what is going on.
    http://www.artstorm.net/journal/2009/07/color-management-wide-gamut-dell-2408/
    Now that is not to say that the 0-255/16-235 issue is not also involved here.  It is definitely possible that a specific codec or compressor is part of the problem, but it sounds like it starts with the color management issue first.
    I hope this helps.

  • Color shift between Library and Develop module

    Hi,
    I recently noticed a color shift between in the image when going from the library to the develop module. Yes, I know this is mentioned in the FAQ, but I did not find the solutions given there to be satisfactory.
    Let me explain what happens: I have taken Photos with my Canon EOS 300D, in Jpeg mode with Color Space in the Camera set to AdobeRGB. The photos I am talking about were taken with Tungsten light with auto white balance and have a distinct orange color cast. I use Windows XP and view my Photos on a LCD Display calibrated with the Pantone Huey system. The Lightroom Library Module and Photoshop CS2 both display the original image almost identically (there are no changes applied inside Lightroom or Photoshop, I view the original image in both applications). Photoshop is set to use the Adobe RGB Color space as its working Color space, Softproofing is switched off. However, when I switch to the Develop Module, the colors (especially the orange hues) shift very noticably toward pink. I can only assume that the Colorspace conversion or maybe some implicit soft proof used differs between the modules. So, to restate the problem: If I switch back and forth between Library and Develop, without changing anything and in 1:1 view to avoid errors introduced by different zooming methods, the colors shift quite drastically back and forth.
    I have to say that this is really quite annoying. The whole point for me to use the develop module is to use it to make adjustments to the colors, and for this to work properly I have to see the same colors in both modules and in Photoshop. There is no point in correcting a pink color cast away in Develop that is not even there in either the library module or Photoshop (and that would then have a stronger orange tint because I tried to counter the pink tint in develop).
    So this leads me to the final question: Is it possible to tell Develop to use the exact same color settings as the Library Module? Or is there another way to compensate for the color shift?
    I hope I was clear in what happens and what I tried to do. If it helps I can gladly provide a sample photograph that clearly illustrates the point.
    Thank you in advance for your help,
    Daniel

    Thanks for your comments, Don and Fred. I hope that this issue will be worked on soon.
    Fred, I have set the Preview Quality to High, but it doesn't seem to make any differences concerning the color shift. I have investigated this matter further by now and made the following observations:
    *The color shift is a lot less noticable on my laptop (the laptop screen is also color profiled). On my laptop the change is more of a subtle shift in contrast than in color. This might be caused by the smaller color gammut of my laptop display though.
    *I have uploaded a testimage so that others can check if this shift occurs at their workstations too - after all, it might be a misconfiguration of my color management software, though I doubt that (because Adobe already states that library and develop render different previews). I would be interested if the color shift I describe is noticable at other workstations too. The link to the testimage: http://www.danyx.com/colorshift.jpg (permission to use the image to test the color reproduction is of course granted hereby).
    Thanks for your help, I hope Adobe will listen soon,

  • Color shift between play and pause

    Hello,
    On CC 7.0 and 7.1, I noticed there is an important color shift between pausing and playing my timeline when using "CineForm Visually Perfect" encoded source material.
    This is especially noticeable on reds.
    Using other codecs, there is no such shift.
    My video card is a Geforce 650M. At first, I thaught it might be related to the video overlay settings of the card, but there are no such settings in the control panel.
    Besides, using Quicktime to play the source produces no shift as well.
    As I am often doing color correction using Premiere, and as I have dropped Avid exactly because I always had this same problem (when using a profiled calibrated screen), I would like to know precisely what is going on. As I'm regularly producing shows for broadcast, it is a real problem not to be sure whether what you see matches the final exported output in all circumstances.
    NB : For the need of searching the cause of this problem I disabled any custom profiling of my screen.
    Thanks ! for any answers.

    Sure and thanks. But nevertheless, if you color correct using a calibrated screen, and produce for the web ; or if you do a first pass of color correction before the ultimate pass happens with a "properly calibrated TV", wouldn't you like that your paused frame would look like your playing frame ?

  • Color shift between Develop Module and other modules in Lr 5.7.1

    Hello,
    I'm getting a color shift between the devolop module and any other module in Lr.
    It's a recent problem that I've been experiencing since the last update.
    I'm using Lr as part of the Adobe Photographers Bundle in a Windows 8.1 pro.
    Below I have an example for the kind of color shift i'm seeing. The image on the left is from the Devolop Mobule and the one on the right is form the Library Module.
    Is this happening to any one else? Does any one know why?
    I would appreciate any help.

    Gautam is correct in that the preview mechanism isn't the same in Develop and the other modules and, you must view the color in Develop at 1:1 to see an accurate preview. The color space is different that's probably why you see this difference in reds (especially if you use a wide gamut display).
    IF you build your own ICC profiles for your display, be sure the software is not building a V4 (version 4) profile, stick with V2.
    As for exporting and comparing, be sure the secondary application is color managed! Otherwise it's expected that there is a visual disconnect between LR and that app.

  • Color shift between viewer and browser after pro kit update

    hi there,
    i thought i be one of the lucky guys since updating and running 3.0.1 was easy on my system. but after yesterdays pro kit update i experience a weird color shift between the look of pictures in the browser and viewer.
    there is a strong colorshift in orange parts of sundown pictures. they turn magenta in the viewer but stay orange in the browser. the difference can easily be seen in the split screen. even weirder if i export a picture from the vier/split screen the exported files show the magenta tint. if i export them from the browser, they have the "right" orange tint.
    this happens with raw-files from both d200 and d70. also exportet the raw and processed it with ps cs3 and everything was ok. anyone got a clue?
    thanx in advance

    just found the explanation. after my prokit update, all raw-files needed to be reprocessed and then i needed to select the standard apple camera module for the d200. that was quite tricky and i don't understand why something like this happens. why do all files need to be reprocessed and than afterwards you would have to manually select the apple standard converter and why did the viewer look different than the browser and why is there no warning module that tell you all files will have to be reprocessed?
