Scanned Import severe color cast problems

Importing into PS (CS3) scanned images via VueScan. When viewed in "Preview": image is fine. We have also viewed image in "GraphicConverter" and again image is fine. When we open the file in PS there is a VERY strong Red color cast which after a lot of manipulation we can get the image looking better but not as "Preview" image.
Any ideas why PS is doing this to the image and ho do we correct it??
Thanks.
Peter

also, try Edit> Assign Profile (sRGB, AppleRGB, AdobeRGB, MonitorRGB for starters)
and check your Color Settings settings (Com+Shift+K) set all three to PRESERVE and check all three mismatches...and do not set Working RGB to Monitor RGB

  • Magenta color cast problem on canon 7d raw files

    when i import canon raw files (cr2) into lightroom 3, i get a magenta color cast over the whole image. the thumbnail image looks fine, but when lightroom opens up the image, it get's a magenta color cast over the whole thing. i shot raw+jpeg mode too, and there's a huge differnce in color between the two. the jpeg looks like how i shot it in camera but the raw image has the ugly magenta color. not only do i get this ugly color, but it seems like there's added noise compared to jpeg image.
    i tried converting the cr2 into a dng. but when i open that in lightroom, i get the same problem.
    i use aperture 2.1 (i only use the lr3 trial so far), but i have the same problem there.
    i use cs3 but i downloaded cs5 trial.
    acr i have is 6.1
    help.
    thanks.

    Go to develop and the callibration tab and change it in the pull down menu to a canon default like 'Neutral' and not the adobe one which is made by somebody totally colour blind or obviously a Nikon fan.
    Although this is weird as the problem for me has always been canon JPG's with the cast and not the RAW.
    Also check your white balance cause Lightroom seems to change it whatever..  'AS SHOT' is a big fat Adobe lie so use a preset from your camera in the drop down box.. Why?  I shoot with Canon's flash WB setting which i know to be 5500k with the tint at zero.  On import, Lightroom changes it to 6150 and adds an amazing +7 on the magenta tint, if i chose 'FLASH' things suddenly turn to what i see on the camera LCD..  I'm sure that is where the big fat tint has come from since day one.

  • Can someone please help a new owner of a Pixma Pro-100 with a color cast problem?

    Despite setting it up correctly with the drivers supplied on the CD for my Windows 7 64-bit laptop, I'm getting a slight pink color cast on both Canon's Fine Art Museum Etching and Glossy Plus II papers. It is neither a monitor calibration nor a software processing (white balance) issue, since I printed exactly the same file on my old Pixma IP4840 without any problem whatsoever. Unfortunately the IP4840 cannot handle the heavier grade media, nor print exhibition grade quality.
    I have tried adjusting the C, M, Y values according to the print pattern as recommended, without any significant improvement. I have used both the Pro and ICC profiles with similar lack of success.
    In desperation I downloaded the 32-bit driver to try on my Windows 8 desktop, also to no avail.
    I'm sincerely hoping there's a simple solution to what has thus far been a disappointing debut to the Pro series.
    Kindest regards,
    Richard 

    no, I didn't ask to burn a picture....this is why I am confused to how the picture got on there.
    I understand what you are saying regarding the multi-session thing (how do I avoid this if my other cds with photos on them have this, and I don't know they do?)
    but what I do know is that cd had photos on it (it definately wasn't full, and maybe that is why I haven't had a problem with others...they have all been full) and no one else uses my Mac, so I know no one else put the picture on that cd. I may have inadvertantly burned the picture, but if I did, I don't know what I did to make it burn the picture onto the cd.....
    The only thing that happened was I opened iphoto so I could save some of the pictures that were already on the disc, but when I went to look for the pictures on the cd, the only thing that was on it, was an iphoto picture....which I didn't ask to be put there.....
    I have previously burned pictures onto CD using my Mac with no problem, and I've pulled pictures off CD that were burned using a PC. So I guess I need to know how to determine if the cds have this multi-session thing going on?

    Lightroom 1.2 as new lightroom user I did not think that I needed to choose a color setting or color profile until I am ready to print my photos. I have not done any preset camera calibration.

    My question is why is Lightroom displaying the images with a yellow color cast ? The image is a print screen from Lightroom on the left and Photoshop on the right The color cast problem can be seen in the white walls of the stairway. Also when viewing the image with Windows Picture and Fax viewer the walls are white as expected.
    Any ideas or suggestions as to why Lightroom is displaying the images with the yellow color cast or what I need to do to correct the issue ?
    Thanks
    Jim

    Almost definitely a corrupt monitor profile. Time and again this turns out to be the cause of such differences between PS and LR. You need to recalibrate the monitor or if you do not have a hardware calibrator, delete the profile from windows' monitor properties pane to test and then get a hardware calibrator.
    P.S since you are using adobeRGB jpegs, Windows picture and Fax viewers cannot give you the correct colors even on a calibrated monitor. Those are not color managed programs (I believe picture viewer finally is in Vista but definitely not in XP which you appear to be using). Also, PS has to be correctly set up to always preserve embedded profiles and to ask when you have profile mismatches, otherwise even PS will give incorrect color. Make sure to set this up in Edit>Color settings.
    P.S.2: Make sure you are not applying defaults in Lightroom to your images either on import or elsewhere. Sometimes people by accident define develop defaults that in this case might contain a white balance shift. Go to LR preferences and open the Presets tab. Here click on "Reset all default Develop settings" and make sure that only the auto grayscale checkbox is ticked. For images that it might have already happened to, make sure to hit the reset button.

  • Color Cast Strips in a Scanned Negative

    I have scanned negatives that show a couple of subtle color cast stripes.  In corrected space these show up as yellow, but in negative space they are only in the blue channel.  The stripes seem to be on the negative and not a scanner artifact.
    Can photoshop mask for these areas and correct the color ?

    Some cross-posting here while I typed up mine (I didn't see Trevor's posts), but I didn't have time to comment further.
    Yes, scanned negatives can be a nightmare. I would never attempt to batch that, I just do the most important ones individually and put the rest back in storage. It's just too much work. However:
    If you have many negatives taken at the same time that show these color bands, you can use the same adjustment layer(s) on all of them. The adjustment layer can simply be dragged from the layers panel over to the next photo; or you can make a preset. If it's a single roll of film you may not even have to redo the mask.
    Another advantage of "painting in" the adjustment is that if you overdo it you can press X and paint back very easily. The example you posted took only a couple of minutes, with two layers - one plus blue to kill the yellow, and then one minus blue for the excess blue on the right.

  • Adobe Camera RAW (All Versions) Import Canon .CR2 / RAW images with an orange / green color cast.

    All versions of Adobe Camera RAW including the latest 7.3 import .CR2 images with a greenish / orange color cast.
    Tested on 7D, and 5D III
    Makes Hardwood floors, and flesh tones look abysmal.
    Canon's Digital Photo Professional renders the colors fine, as does ACDSee 5.0 Pro (when viewing)  Exporting from ACDSee however is another story as things look even worse than Adobe.  DPP can export perfectly.
    Changes to Color Gammut / Space have little or no effect.

  • How to reduce purple color cast in high ISO Nikon D4 and D810 photos

    In low-light photos taken with my D4 and D810 I often (but not always) get a severe purple color cast in the dark areas of the photo. I'm going to try posting a link to an example of one such photo, which I've put in my Dropbox account. I hope this works:
    Dropbox - Example of magenta color cast-001.jpg
    If the link works, you'll see what I mean: the dark areas are purple, not black as they should be. This was taken at the dress rehearsal for a play at ISO 3200, about the lowest ISO that I could get away with. The purple cast seems more pronounced along the edges of the photo.
    I've read a bit about "amp glow"; is that what I'm seeing here? If it is, what can I do about it? Turning the camera off and on again and again to try to cool the sensor and the nearby electronics isn't much of an option.
    And whether it's "amp glow" or something else, is there a good way to deal with it in Lightroom? I've had some success with reducing the purple saturation (and sometimes the purple luminance as well) in the "HSL" panel, but that becomes a problem if there are important elements in the photo which are SUPPOSED to be purple.
    Any and all advice would be welcome.

    dorffersmatt wrote:
    Interestingly, my e-mail says there was another post about how to reduce the purple cast with proper in-camera settings, but now that post seems to have been deleted (by the poster? by somebody at Adobe?)
    The poster (Drugstore) may have deleted the post after reading further because it may not have been relevant......just a guess. If you're shooting raw format the in-camera settings such as white balance are not applied to the image file, but they are for JPEGs. The suggestions I provided are applicable to both JPEG and raw image files, but you'll get the best results using raw format.
    dorffersmatt wrote:
    1) You said that you sometimes see the purple cast with your D4 and D810 if the white balance isn't set properly. What would you consider a proper white balance setting for a situation such as this one? It was the dress rehearsal for a play, with constantly shifting lighting. I just left the white balance on "Auto"; how would you have approached the situation?
    Again, this only applies to JPEG format image files. For raw image files the WB EXIF data is read and set accordingly inside LR. For JPEGs the image data has the (incorrect?) WB applied in-camera, which compromises the dynamic range of the JPEG 8-bit/color data. Raw files are 16 bit/color.
    dorffersmatt wrote:
    2) You said that you also sometimes see it if "you activate the lens correction in LR while in raw mode and exposure is too low." Could you elaborate on that? Do you mean that I shouldn't use "Enable profile corrections" in the "Lens Corrections" panel?
    I'm guessing this refers to what you call "amp glow" (amplifier glow). It usually appears as a higher exposure level around the edge of the image and may be confined to one area (top, bottom, sides). By turning off Lens Profile corrections ( "Enable profile corrections") Vignetting correction is not applied, which reduces the exposure level in the corners and frame edges. Some cameras automatically apply distortion and/or vignetting correction in-camera when shooting in JPEG format. Again, this is just another reason why you want to use raw format to get the best results inside LR.

  • Blue Color Cast when Printing

    I have just carefully calibrated (again) my Canon Pro 9000 Mk11 Printer and Asus Pro Art screen using Spyder equipment.
    Printing in LR4.4 consistently produces a blue cast.  I moved to Elements 11 and using the same just created profile printed the same picture/file.
    No color cast.
    I have LR5 Beta also so I printed same on it.  No color cast - to all intents and purposes identical to Elements 11.
    'Perceptual' setting used throughout and no 'Print Adjustment' used in LR.
    I am using Windows 8 64bit.
    Why should LR4 only produce a color cast?  The settings have been carefully checked ...

    Hello:
    I'm not sure of site etiquite, whether I should ask another's advice about a separate problem, but my dilemma is so much like this and I have not been able to fix it on my own nor with Adobe or Epson's tech support.
    I too am getting out of my printer only prints that have a blue cast to them. My printer is an Epson r2000. I print from Lightroom 5 and Photoshop CS 6 or now its Creative Cloud equivalent. Yesterday, the i7 laptop I have been using for photo editing (with a better monitor attached) started producing only bluish prints--intended to be black and white (the max whites are white but everything else has a blue cast). It also was apparent in color prints when I tested that alternative. I was not too concerned because yesterday FedEx also delivered a gonzo new desktop computer that I had ordered just for photo editing. I thought, "Well, I'll install all my Adobe stuff there and migrate the Lightroom files and everything will be OK." But, immediately, the blue-cast problem showed up on the new computer. I thought I probably "migrated" the problem when I brought over my catalog, images and settings from the laptop.
    I reinstalled the newly installed printer driver and reinstalled the latests ICC files for the papers I use (Ilford Gold Fiber Silk and Gold Fiber Mono), but the problem persisted. I didn't yet know about blowing off the preset files.
    I spent a lot of time on the phone with Epson yesterday and chatted at length (1 hour 39 minutes) online with Adobe tech support today. Adobe had me do what you recommended--blow off the preset files and begin again, all to no avail. On my own, I again deleted and reinstalled the printer driver and wiped out the preset files.
    Still, I get a bluish overlay on my prints.
    After reading your posts, I meticulously checked my settings. Everything seems alright.
    I did one other thing. I printed images that had not been imported to lightroom in Windows Photo View through the same 13-inch Epson. They came out perfect.
    Now, I just don't know what to do next. Epson and Adobe support have done their apparent best. I live in a small town at the end of the Columbia River where I am looked upon as one of the computer problem solvers (a degree in Literature notwithstanding).
    I've thought of blowing off lightroom 5 and going back to version 4, but, as I understand it, that would mean losing all my metadata for some 40,000 images dating back to 1966, most of which I had to plug in by hand since they are from scanned negatives.
    Do you have any advice?
    I am a little anxious because I am supposed to have prints ready for a show opening on July 27.
    Thank you in advance for any advice you may offer.

  • Media Encoder adding RBG color casts on BW 16mm Footage

    Hey Everyone,
    I am really stumped by this one. I am working with FCP6 and Apple Pro Res HQ scans of 16mm B&W footage. I am trying to encode a self-contained .mov file (direct from FCP) in Adobe Media Encoder CC (for Blu-ray) and then burn to Blu-ray with Encore CS6.
    I burned the first test Blu-ray last night and when I played it back on my Blu-ray player/TV, I was stunned by the fidelity and definition of the otherwise thick/complicated 16mm grain structure, even via what was only a 6GB .m4v render (compressed from 33.5GB .mov). Everything was perfect...EXCEPT...I got these horrible "color casts" of red, blue, green, magenta, across practically every shot in the footage. Particularly in the last shot of the drain pipe (see example clips 14 seconds long):
    Original: https://vimeo.com/97456916 (pass: "original")
    Blu-ray: https://vimeo.com/97453674 (pass: "colorcast")
    Obviously the footage does not look this in either FCP6 or .mov in QT7. I just double checked and the color casts ARE visible when playing back the ME converted .m4v in Encore. I have also taken the .mov from FCP and brought that into Encore and NO COLORCASTS. I have also taken the .mov, reimported it to FCP and but a 3-Way Color Corrector on it and put the saturation at zero, exported that, and then ME>Encore and it still adds the color....So I am 99% positive this is a Media Encoder issue. Here are the settings I used:
    Considering how long is has taken me to get satisfactory web compression results from 16mm footage in the past, I feel like I just hit a grand slam in the bottom of the 9th with the playback fidelity of the first test Blu-ray. The motion and definition are phenomenal, I mean we are talking Criterion quality--without X.264 or Blu Code--(even with all the modern "overcompensation" crap turned off on my TV). I AM SO SO CLOSE TO RENDERING/BURNING A PERFECT BLU-RAY IF I CAN JUST FIGURE THIS COLOR THING OUT!
    Got a deadline to get this into the hands of a couple of prominent filmmakers.
    Any help or ideas that anyone can provide will be most appreciated.
    Thank so much!

    ***SOLUTION***
    Well it seems silly that I had to do this at all, but here is the workflow that finally seemed to solve the issue without adding an extra level of encoding...
    Save self-contained .mov of my timeline in FCP6 > bring that back in FCP as a separate sequence and apply the "Desaturate" filter (Image Control > Desaturate) to the entire film > save as self-contained .mov again > convert in AME > master and burn to Blu-ray with Encore > Presto!!! NO COLORCASTS on B&W 16mm footage in Encore and no colorcasts from the file on the burned Blu-ray disc.
    I believe I stated it above, but in case I didn't, adjusting the chroma and/or "desaturating" via FCP's color corrector plugins did not work...even with the exact same workflow otherwise. I have no idea why, but if anyone ever runs into the same problem, this worked for me. Only took two weeks to do something that I guessed would take a day, maybe two. Geesh.
    Thanks again guys for all the suggestions. Really really appreciate it.

  • How to easily spot color cast in aperture

    Hi,
    I am having difficulties to properly spot/analyze a color cast in my (scanned from color negatives) images. There is no neutral grey or white present and I'd like to get a handle on correcting this color cast without just trial and error (and making things worse)
    Any hints or ideas? Pointing me to a resource on the web to find out how?
    (Spotting and correcting the color cast in my scanning software (Silverfast Ai) didn'd work as well)
    Thanks a bunch,
    Rolf

    Hi Rolf -- you're question is not really answerable.  Color is almost entirely subjective -- we color our world in our brains, and then we make machines to mimic this (digicam sensors don't record color -- they record luminance as filtered through known colored gels).  Your question presumes an objective standard of color correctness.  That does not exist.
    Nevertheless, you can at least maximize your ability to get the colors as close to "right" as you can.  For that you need a color-calibrated workflow, from input (scanner) to output (whatever).  There is much information on this on the Web.  For Aperture, you'll want a hardware photospectrometer to calibrate your monitor(s) and whatever paper you print on (if you print).  I use a Color Munki Photo, and recommend it or something similar.  (X-Rite has recently announced a revamped product line.)  X-Rite also makes a calibration tool called a Passport.  This has several colors and shades of gray of known hues.  In use, you make an exposure of these colored squares, and then use them to set the white balance.  You might be able to something similar with a scanner.  (I don't use one, and don't know anything about scanner calibration.)
    HTH.  Sorry not to know more.

  • Pinkish Color cast in iphoto 08 ?

    Hi everyone,
    I recently purchased a new mac with ilife 08. I noticed in iphoto that when i double click on a picture and it enlarges it, i get a pinkish color cast over the picture. it does it with all the pictures in iphoto. the thumbnails in iphoto look fine. its just when i click to view it larger or in edit mode that i get the strange color cast. does anyone have any ideas what is causing this? I have tried searching the apple support forums , but i am not finding anything on this problem.
    Any help would be appreciated.
    Frank

    Frank:
    If you plan on ordering a book or other printed item using the monitor's color profile might not give you what you want. I have calibrated my monitor to the sRGB profile plus a change in gamma for brightness. This has given me excellent color rendition in any book, card or calendar that I've ordered.
    You might try printing one also to see if it gets what you expect.
    TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
    I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 6 and 7 libraries and Tiger and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

  • Third-party plugins and color cast

    Hello,
    When using DE:Noise or Magic Bullet Denoiser 2, I get a color cast on the whole image when it is applied simultaneously with a color correction via a Lumetri effect.
    I have tried everything inside Premiere regarding effect order, nesting, and adjustment layers. No matter what, the color cast is always there. On the contrary, if I export the color corrected footage, then import back, then apply the denoising, there is no problem.
    Any help ?
    Thanks

    The transitions in FCP are the same. Transitions are not keyframeable, clips and filters are keyframeable. There might be some third party transitions. You could try google.

  • Strange yellow color cast after CS4 install

    I just ran into a strange problem helping a friend install PS CS4. Everything seemed to go fine, but now all of a sudden his images are displayed with a strong yellow tint. I don't mean a slight color cast, I mean a STRONG yellow tint. The images appear the same in Photoshop, the Bridge, and even ACR. I re-calibrated the monitor (Gretag McBeth) and generated a new profile just be sure, but that wasn't it. The same images viewed in other applications (Picassa, opened in a browser, etc.) on the same computer display normally. This appears to be only Photoshop related. What's also interesting is that CS3 now exhibits the same problem after the CS4 install.
    I reviewed all the color settings and workflow, and nothing is out of the ordinary. The Nikon raw images were imported via ACR, and opened in Photoshop with ACR workflow options set for 16 bit/Adobe RGB. Photoshop working space is Adobe RGB. I also installed the 11.0.1 update. But here are what may be a couple of clues. First, it's not just the image files that look bad. The colors are awful in the color picker in the toolbox. The entire color picker slider is almost all yellow and orange. And here's another good one. We tried importing some new raw images via the photo downloader in Bridge. With the downloader in Advanced mode, the image previews before download show the same yellow cast. But after I click the Get Photos button, the image colors appear correct as they flash on for a couple of seconds while being downloaded. This has got to be a big clue for someone. What's different about how the image is displayed during that two second preview during the actual download?
    The PC hardware is a 3.2Ghz Pentium 4 Dell tower (2G ram) running XP Pro w/SP3, with a nVidia GeForce 7800 graphics card, and the screen resolution is 1024x768. I'm thinking maybe a graphics card issue or corrupted system profiles, but I'm a Mac and he's a PC so my PC troubleshooting skills are limited.
    Has anyone else seen a problem like this before?? Any ideas? Thanks!

  • Panasonic GF1 horrible color cast

    It seems that Aperture has some serious issues with a magenta color cast when converting GF1 RAW files. It's not so apparent with 100-200 ISO (but still there, especially whith large white balance shifts) images but once you get to ISO 800 the images become unusable.
    The color cast is mostly apparent in the dark(er) parts of the image.
    Check out the following links to some quick test images that illustratie the problem perfectly. The first link is the image developed in Aperture (latest version) with the white balance set on the white wall in the background. The second link is the same image developed through the latest Camera Raw with the white balance set in the exact same spot.

    The Camer Raw image is perfect. Is anybody else seeing this issue with the GF1 (or other Panasonic cameras with similar sensors). It makes using the GF1 with Aperture impossible.
    It's quite unfortunate as Aperture performs great with my D700 images and I really don't want to switch to Lightroom because it's horrible as a library management application compared to Aperture (altough Camera Raw is giving me better results and noise reduction, lens correction and split toning are great, but I digress...).
    Also check out this thread for a similar experince with the GH2 (+4 months old):
    http://forums.dpreview.com/forums/readflat.asp?forum=1041&message=37849807&chang emode=1
    The people in that thread have sent feedback to Apple and AFAIK this hansn't been resolved yet so I'm not getting my hopes up.

    Raw files are not visible. They must be converted to an image file format in order to be seen. This is done in-camera for display on the LCD screen, and for export of JPG (or other) files. For almost all cameras, any processing which changes the appearance is done to a JPG file.
    When you import raw files +you do not get the JPG processing+. That's what raw is -- it's the light information prior to being converted to an image format. (The are enormous advantages to having this data available.) That is why your raw file previews are in color.
    There are a number of monochrome and grayscale conversion presents in all raw development programs. It is generally accepted that these do a better job than most of the in-camera converters. There is no question that they give a choice among many -- as well as the ability to tweak them to your heart's -- or your printer's -- content, unlike the baked-in conversions done in-camera.
    In short, raw is never black & white or monochrome. Adobe has a good older white paper on raw which is worth reading: +Understanding Digital Raw Capture+.
    OS X is working correctly.
