Lens Profile

Please, I need your help - how can I request a lens profile - my camera is SONY NEX-5N, E 18-200mm F3.5-6.3. With Adobe Lens Profile Downloader I found end downloaded a profile for raw. How about jpeg? Any help will be appreaciated!
Mary Christmas and Happy New Year!

You can also use the Manual controls if you want to deal with distortion, CA, vignetting, etc.

  • GoPro Camera Raw Lens Profile settings not working for image sequence in Photoshop/AE/Premiere CS6

    Hey Everyone,
    I'm in need of assistance in either Photoshop CS6, After Effects CS6, or Premiere Pro CS6.  I just installed the trials after seeing Russell Brown demo the GoPro Lens Profile correction feature in Camera Raw.  Basically what I'm looking to do is make adjustments (in Adobe Camera Raw) to a series of still images (shot with the time-lapse mode on the GoPro) and then either export those stills through Photoshop or Bridge to a temporary movie file that will be imported into a timeline (with other video clips), or import the JPG files (with Camera Raw settings) directly into After Effects or Premiere as an image sequence.  The latter would be preferable as it'd avoid the extra step of having to render the intermediate/temporary movie file.
    Right now, my current workflow for GoPro time-lapses is:
              - use Bridge CS4 to do basic color correction on the still images
              - save those as TIF files
              - run the TIF files through a custom script to have Hugin 2012.0.0 (open source pano stitcher) remove the fisheye distortion
              - open the new TIF image sequence into QuickTime Player 7 (Pro)
              - export the image sequence as a QuickTime movie file
              - import the movie file into Premiere Elements 10 to place on a timeline with other video clips (as Premiere Elements can't handle the sequence(s) of thousands of still images without crashing)
    If I can go directly from Bridge to a timeline, it'd save a lot of processing time (and it'd be much nicer to preview the images in Bridge without the fisheye distortion)!
    I can prepare the GoPro JPG files through Adobe Camera Raw in Bridge CS6, though when I go to import the JPEG image sequence into Premiere Pro CS6 or After Effects CS6, none of the Camera Raw settings are applied.  If I export the Camera Raw files in Bridge CS6 as DNG files (a step I'd really prefer to avoid) and then import the DNG image sequence into After Effects CS6, the Camera Raw settings are applied except for the Lens Profile settings -- I can pick other cameras but not the GoPro lens profiles when the DNG image sequence loads in After Effects.  It also appears that once I open the DNG files in After Effects CS6, I can no longer access the GoPro Lens Profile in Adobe Bridge CS6 -- the list changes to the same list I get in After Effects.  Premiere Pro CS6 doesn't let me import the DNG files at all.  I've also tried to import the JPG files (as well as the converted DNG files) into an image sequence in Photoshop CS6, though it doesn't allow me to do so (the Image Sequence checkbox is grayed out after I apply the Camera Raw settings in Bridge).
    There could be an issue going on with different Camera Raw versions.  I didn't have Premiere Pro CS6 installed during my initial testing, though now do notice that the Camera Raw dialog in Bridge CS6 only lets me choose compatibility up to "Camera Raw 7.1 and later" when I choose to export the files as DNG.  I thought Camera Raw 8.2 was an option there a couple days ago when I only had installed Photoshop CS6 and After Effects CS6 (though am not 100% certain).
    Please let me know if there is some workaround to get the GoPro lens profile Camera Raw corrections applied in an image sequence in one of the Adobe CS6 products (without having to export the files as temporary TIF or JPG files out of Camera Raw).  I'd greatly prefer to shorten my current workflow for these files.  (I just updated the CS6 trials and have tested all three programs again though I still get the same results described above.)
    Does Lightroom 5 have any option to export Camera Raw image sequences as movie files (or any other feature that might help in simplifying my current workflow)?  I can't install the trial right now as it's not compatible with OS X 10.6.8.  I'd consider upgrading OS X if I knew Lightroom 5 would do what I need, though am waiting for any potential color profile issues to be resolved in OS X 10.9.
    I can open the image sequence in Photoshop CS6 if no Camera Raw settings are applied and then use the Lens Correction Filter to apply the GoPro Lens Profile settings, though I really prefer the Camera Raw interface in Bridge for tweaking image settings.  As soon as I apply Camera Raw settings to the first image, Photoshop CS6 grays out the image sequence checkbox.
    If there isn't a way to take Camera Raw files straight from Adobe Bridge to a timeline, I may stick with my current workflow using CS4 and see what I can do to better automate some of the steps as the TIF export in Bridge, fisheye distortion removal in Hugin, and render in QuickTime Player all take quite a while.  I won't mind waiting for all the processing if I can set it and check back on it in later the next day when it's fully complete.  Is there a way to have Adobe ExtendScript execute an external shell command (i.e.: a command I could type into the bash shell in Terminal in OS X)?  If not, is there a way to call/run an ExtendScript script from the command line and pass a parameter to it that my custom script could use?
    Thanks in advance,
    Mark

    Can you zip up a few of your GoPro images, upload them to dropbox.com and post a share link, here, so others can experiment with them, or do you mean this issue is global to all camera models?

  • Lightroom Bug: with GoPro Hero4 Silver Lens Profile, crop settings do not sync properly in Lightroom 5.7.1 when Constrain To Warp is checked

    I was having a bit of difficultly in getting crop settings to properly sync in Lightroom 5.7.1 (running on OS X 10.10.1) when Constrain to Warp was checked.  This appears to be a bug in the latest version(s) of Lightroom that include(s) the GoPro Hero4 Silver Lens Profile settings.  I'm working with a lot of files from a GoPro Hero4 Silver camera shot in the time-lapse / interval timer mode.  All of them are horizontal with the same resolution (and dimensions).  I've tried various sequences to get this to work in terms of using Auto-Sync, resetting the settings on all images except one and then copy and pasting settings, etc, though the crop is not properly syncing regardless of what I do.
    Here's are instructions of how to duplicate this issue (there are some extra details/steps here, though this should be clear enough to produce the same result):
         1.  in the Develop settings for a single selected image, go to Lens Corrections, click to Enable Profile Corrections (in the Profile tab), and then pick the GoPro Hero4 Silver Edition (Adobe Profile) if it is not automatically chosen for you (if you are using files from a Hero4 Silver camera).  After this, click on the Manual tab, and set the Scale setting to 76.  (as you will see, you now have the full horizontal width of the image that was getting cropped off, though you do see white around the edges that have been warped/shaped to correct the fisheye distortion)
         2.  Press the R key (or click on the Crop Overlay tool just below the histogram).  Change the Aspect option to Custom.  Click to unlock the lock next to it (this seems to re-lock after setting to custom even if it was locked before).  Place a checkmark next to the Constrain To Warp option.  (At this point, you'll see the image gets cropped back to an approximately 4:3 ratio and the full horizontal width is not included in the cropped area)  Click the upper right most corner of the crop area and drag as much to the right and top as it lets you go.  Do the same for the lower left corner, dragging it as far to the bottom left as you can go.  (Now, you will see that your cropped area is the maximum rectangular width and height you can select without getting any of the excessive white area)  Click the Close button (or press R again) to leave the crop overlay tool.
         3.  Press G to go back to the grid of images.  Make sure the image you just adjusted the settings for is the only one selected.  Right click on it, go to Develop Settings, and click Copy Settings.  Click Check All on the window that appears and then click Copy.
         4.  De-select the image you were working on.  Select multiple other images in the grid.  Right click on one of these, go to Develop Settings, and click Paste Settings.  (at this point, you will see their aspect ratio has become more panoramic than the 4:3 aspect ratio the images previously were)
         5.  De-select these images.  Select one of these image, and then press D to go to the Develop settings for this image.  Press R to go to the Crop Overlay tool.  Here you will see the bug where the crop was not properly copied over from the first image.  The selected area is smaller than the full width and height available to crop.
    It seems that the bug is that Lightroom is only copying the aspect ratio (and the other settings), but not the actual crop selection.
    I just thought of a workaround that I've tested and can confirm works (and will also work in a slightly different workflow than above).  In step 1 above, for the Model (and Profile), manually pick the "GoPro Hero4 Black Edition" or the "GoPro Hero3-Silver Edition".  If using the "Hero3-Silver" setting, the Scale (also in step 1 above) need only be set to 79 (rather than 76 for the Hero4 profiles).  By picking one of these Lens Profiles and doing everything else the same as the other steps above, the crop settings do copy and paste properly.  This does also appear to work properly when selecting the "GoPro Hero3-White Edition" Lens Profile, with a Scale setting of 75, which yields a slightly more rectilinear image (with a wider aspect ratio -- almost, but not quite 16:9).
    While this isn't too big of deal as it does work by picking one of the other lens profiles (and the Hero4 Black Edition profile appears to make the same exact correction to the image), this was incredibly frustrating last night to notice that some files had the proper horizontal field of view / crop and others didn't, and other users may experience this or not even notice their crop is not copied properly (as, depending on one's composition and image, it's not extremely obvious with such a wide view).
    I hope this discovery helps someone else and provides feedback for Adobe to correct this issue in the next version of Lightroom 5.
    On a separate, additional note for Adobe:  Please allow the crop overlay tool to "crop" an image to a size that is larger than the original dimensions of the image.  This would allow for one to retain maximum original sharpness in the center of the image when using the Lens Profile tool to correct, or "de-fish" a lens, without having to scale the image down with the Scale option on the Manual tab of the Lens Corrections settings.  For example, when I do the above process selecting the Hero3-White Edition profile, my final image dimensions are 3840 by 2257 pixels, reducing the size of the image in the center by 25%.  If the tool allowed one to crop/scale a larger image size, and I kept the Scale option of the Lens Corrections settings at 100 rather than 75, my final image dimensions would be 5120 by 3009 pixels (larger than the 4000 by 3000 pixel dimensions of the original image which the tool now limits me to).  Yes, the edges would be a little softer but the center would retain the original detail.  (this is essentially what the Calculate Optimal Size button found in the Hugin open source software does, when using it on a single image for lens transformations/corrections)

    Can you zip up a few of your GoPro images, upload them to dropbox.com and post a share link, here, so others can experiment with them, or do you mean this issue is global to all camera models?

  • How is the best way to capture frame in Lens Profile Creator?

    Hello, I read in the Shooting Guide related to Adobe Lens Profile Creator:
    When framing the chart in different areas of the image frame, use a combination of physically moving and tilting the camera to achieve an optimal balance for LCP generation.
    i. Only moving the camera to frame, so that image plane stays perfectly parallel to the chart, can have an adverse affect on LCP calibration data.
    ii. Only tilting the chart may cause depth-of-field issues, where part of the chart may go too far out of focus due to the large angle of the chart in regards to the image plane. This can also have an adverse affect on LCP calibration data
    Ok, but I'm not able to understand at all, please help me:
    1) is it better if I'll rotate the camera on tripod to left and to right or is it better phisically moving the tripod to left and to right?
    2) is it better if I'll tilt up or down the camera on the tripod or it's better picking up or down the tripod bar?
    3) if it should be better make a combination of tild and rotate and move the camera how can I know the optimal combination?
    I hope that someone who has experimented this could explain me better
    Thank you everybody
    Damiano

    I don't know what is technically optimal, but there is an aspect of practical convenience here, as well.
    In my experiments with this, I physically moved the tripod in the left-and-right direction, and then re-aimed the camera vertically as required in order to put the target into the desired part of the frame. I was happy with the results, though I did not make any deep comparative study.
    IMO whatever technique permits you to make a sufficient variety of reasonably careful acquisitions, without being unfeasibly difficult, and which the analysis tool does not reject, is probably going to be good enough.

  • Why don't additional downloaded lens profiles show up in LR5?

    Hi everyone! My name is Kai and this is my first post here. Normaly I find an answer to all my questions by reading already existing discussions. But this time I wasn't lucky...
    Hopefully this is not a stupid question.
    I downloaded lens profiles for the Rokinon 7.5 fisheye and created a folder named "Rokinon" in "Rsources", "LensProfiles", "1.0" (MAC OS) to put them in, but they don't show up in LR5 and I can't use them. What's wrong?
    Thanks, Kai.
    <moved by mod from downloading,installing,setting up - kglad>

    The correct location to place downloaded Lens profiles on a Mac is:

  • How do I create an ACR custom lens profile if camera exposure can't be set to manual?

    How do I create an ACR custom lens profile if camera exposure can't be set to manual?
    I ask this question for the Nokia 808 PureView 41MP camera. It produces stunning image quality but exposure can only be controlled via EV +/- compensation. I need a lens profile to correct for vignetting to get even skies in panorama (which turn out stunningly otherwise). There is no profile for the Nokia 808 PureView I am aware of and I'd like to produce one.
    Is the Adobe profile creator able to correct for varying exposure using EXIF or overlapping parts of the chart or background?
    Or would the Adobe profile creator ignore EXIF if I use studio flash to enforce a constant lightning situation, even if shutter speed would vary (aperture is constant and ISO can be set constant, just not the shutter speed)?
    Or did Adobe produce a profile internally they can share?
    Thanks.

    If you read the first post, this is the camera-app of a 41MP Nokia Pureview 808 camera-phone, so maybe someone could write a new camera app but the phone is Symbian OS which is dead, making that unlikely.
    http://www.digitaltrends.com/mobile/the-skeptics-guide-to-nokias-808-pureview-five-reasons -41-megapixels-are-not-a-gimmick/
    http://www.digitaltrends.com/mobile/the-nokia-lumia-820-and-lumia-920-too-little-too-late/
    It would probably be easier for Adobe to rewrite the LPC to allow vignetting to be computed from a single shot of a blank wall without a target in the shot, than to have someone rewrite a camera app that allows manual exposure.
    Another idea about how to get the phone to keep a constant exposure would be to experiment with putting darker and lighter objects in the field-of-view away from the target area to make the camera metering adjust things so it’s exposure is the same from one shot to the next.  This would take some doing but should work, unless the LPC uses the part of the frame that doesn’t contain the checkboard target in its computations.
    You’re basically varying the scene around the target so the camera takes the same exposure of the target each time.

  • Is there a lens profile for Samyang 14mm and Canon 5D2 ?

    Hi !
    I'm thinking about buying a new Samyang / Rokinon / Bower etc 14mm wide angle full frame lens.
    However, this lens has bad moustache distortion on stills images - not good for architecture.
    Is there an Adobe lens profile for Adobe Camera Raw (Photoshop CS6 Bridge) for full frame Canon 5D2 / 3 or 1Ds 3 etc ?
    It's needed for Mac - don't know if there is any difference.
    Advice before I buy would be much appreciated ...

    Yay that's great news ... and thanks for such a speedy reply.
    Didn't know about the Adobe Lens Profile Downloader ... so have just downloaded it for Mac and found the lens profile.
    Appreciate your help ... it'll hopefully be great for correcting the distorion i need.

  • Does the Lens Profile Creator work with Photoshop Elements 8.0..?

    Hello,
    I am very new to the world of Photoshop, so please forgive if this is an obvious/stupid question...
    I am using Photoshop Elements 8.0 and I have a couple of pictures that I need to remove the 'fish eye' lens distortion from around the edges...
    The blurb for the Lens Profile Creator says that it is for use in the "Adobe Photoshop® family of products"...
    Does this include Photoshop Elements 8.0 or do they really mean it is just for Photoshop CS5, Camera Raw and Photoshop Lightroom...
    Any help will be appreciated...
    Many Thanks

    PSE does not have the user-interface to turn on lens-corrections, nor does the ACR 6.1 update for PSE contain the lens-profile database installer, so if PSE is the only member of the PS-family that you have installed then effectively you cannot apply lens profiles.
    If a computer has the lens-profile database installed and lens-distortion-correction has been enabled in the XMP sidecar for a particular image, both requiring PS-CS5's ACR 6.1-updater or LR3 to be installed and one of those used to enable lens-corrections for the image, then PSE can use ACR 6.1 to apply a lens profile, because the version of the ACR 6.1 plug-in for PS and PSE is the same plug-in.
    BTW, removing fish-eye distortion completely, which is what enabling lens-corrections does by default, will leave a rather poor looking image that has been completely rectilinearized but has severe stretching of the pixels at the edges, so only the center is useable.  With my 8mm Sigma fisheye, I reduce the Distortion part of the correction down to 44 so the black corners are gone, but there is still some bulging of the image.
    If you want to experiment with lens-corrections, you could install the 30-day trial of LR3.

  • Adobe Camera Raw Save Settings and Lens Profile Corrections Help

    I have been fooling around with Adobe Camera Raw’s (ACR) ability to save settings so that I can apply them to other images. I’m able to set things such as clarity, vibrance, camera profile etc. What I want to do is enable Lens Profile Corrections and have it automatically detect the lens information for future images, apply no distortion corrections and apply vignetting and chromatic aberration corrections. However, when I try this, the Lens profile sticks on “Canon EF 24-105mm f/4 L IS USM” (which is what I used for creating the settings to be saved) regardless of the lens used for the image that I am applying the settings to. Is there a way do this?
    I’m using Photoshop CS6 and ACR current version.
    Thanks,
    Mike

    You should see an Adobe Standard profile and perhaps an ACR x.x profile for your camera, but Adobe does not make Camera-centric profiles (landscape, portrait, camera neutral, etc) for most cameras unless they are Canon DSLRs, Nikon DSLRs, one Leica and a few Pentax cameras.
    On a Vista/Win7 system you can verify what models of cameras are supported by Adobe by looking for profiles in:
    C:\ProgramData\Adobe\CameraRaw\CameraProfiles
    The lens profiles are in:
    C:\ProgramData\Adobe\CameraRaw\LensProfiles
    There are comparable directories on Win XP.

  • ACR 7.1 Beta & Photoshop CS6 Lens Profiles

    If I open a Nikon RAW (NEF) file in ACR 7.1 Beta it correctly finds my Camera and Lens Combination Nikon D3 with the Nikon 24-70m f2,8 with the Adobe Lens Profile. However, when I leave ACR and the image is open in Photoshop, go to Filter, Lens Correction it does not automatically detect the correct camera and lens combination.
    It shows the Camera Make as NIKON CORPORATION, but the Camera Model and Lens Model are not detected and I am asked to choose. In the Lens Profiles I see two choices, one for a Nikon D3x with the correct lens, the other for a generic Nikon Camera with a Sigma 24-70 F2.8.
    I would have thought the detection process would have been the same?
    MK

    I was just curious and hunting around ACR 7.1 and Photoshop trying our the features. Also I have found that LR4 RC2 has follows ACR 7.1 as far as lens profiles go working with RAW images, so there is some consistency.
    Wonder what the difference is between a RAW rendered image in ACR versus a Photoshop rendered image. Given, I could be wrong here, that Lens Correction is based on the optics of the lens, focal length, and the characteristics of the sensor, so would they not be the same in ACR and Photoshop? 
    I think I need to go check out a lens profiler
    Cheers
    Mike
    There is one reason that I may go back into the Lens Correction Filter and that might be to fine tune some of the persective tools. With a large panorama much easier to see what needs to be done rather than view seperate images, and i have done that in the past. did not come to me until after I had hit the Send Button

  • Lens Profile Support LR5

    Lens profiles not showing up in LR 5.
    Working on a Mac 10.7.5, Photoshop CS6, and Camera Raw 8.3 installed. In Lightroom 4, my Canon 6D camera was supported, all lens profiles appearing in LR, was able to choose my Tamron 28-200 mm profile for raw images. Have installed LR 5 and no profiles are coming up. The profiles all appear in: Mac/Library/Application Support/Adobe/Camera Raw/Lens Profiles, on my system, but I cannot seem to get them to appear in LR 5 so I can choose my lens for "Enable Lens Correction" option.
    Have opened a raw file in PH 6, Lens correction, my correct lens is appearing, but says it cannot be found online.
    Any ideas or suggestions, thanks

    Do you have the latest camera raw installed for Photoshop? If so, you can find the profiles in /Library/Application\ Support/Adobe/CameraRaw/LensProfiles/1.0/Nikon/ . Lightroom should recognize them if you move them into your home directory's Library folder in the exact same folder structure (but in the Library folder in your home directory). This is assuming you are using Mac OS X. No clue where these files would be on Windows. If you don't have Photoshop, you can install Camera Raw using the combined installer with DNG converter which is a free download from Adobe. This should (I think) give you the profiles in that exact location without owning Photoshop.

  • Lens Profiles not working in Lightroom 5.4?

    I've got OSX 10.9.2, Lightroom 5.4, latest Camera raw, everything up to date.
    When I "Enable Profile Corrections" for an image shot with a Sony a7r and Sony FE 55mm lens, it should automatically retrieve this profile:
      /Library/Application Support/Adobe/CameraRaw/LensProfiles/1.0/Sony/SONY (Sony FE 55mm F1.8 ZA) - RAW.lcp
    Well, it doesn't.  The only Sony lens available in Lightroom's Lens Correction panel is "Sony DT 18-200mm."  But there are several dozen Sony lense profiles in the "Sony" directory.
    And more puzzling, the camera "Make" menu lists 8 manufacturers (Apple, Canon, DJI, GoPro, Nikon, Sigma, Sony, Tamron) but leaves out a number of others — Fujifilm, Hasselblad, Leica, Mamiya, etc.
    And as with Sony, only one Tamron lens is listed.
    I've tried re-installing Lightroom fresh, and no luck. 
    Photoshop works fine and has all the lens profiles.
    Anyone else noticing this?  Got a fix?

    I only shoot in RAW, and I am having this same issue. I shoot Nikon with a Tokina lens. This morning, Tuesday October 14, 2014, I had this setting. I closed the program and restarted it, and now I only have Apple, Canon, DJI, GoPro, Nikon, Sigma, Sony, Tamron lens profiles. There was not an update, nor did I actually change any settings. What is going on here?
    I talked to customer support, whom suggested that I was stoned out of my mind because these profiles do not exist in lightroom. I did as the rep asked, followed the link and downloaded the "new" profile. Now I can't get it installed. Meanwhile, my photos are waiting for me to edit them. Can someone please help out here?!

  • Lens profile not recognized by LR 5.3

    At work, on a Windows 7 laptop, I used the Adobe Lens Profile Creator utility to make an LCP file for a Nikon 1 6.7-13mm zoom lens.  After submitting that LCP file to adobe via email, I copied it to my Dropbox.  At home, on my Mac OS X 10.8.5, I copied the LCP file from the Dropbox to:
    \Library\Application Support\Adobe\Camera Raw\Lens Profiles\1.0\
    Then I launched LR 5.3, navigated to a raw (NEF) image shot with this lens, and attempted to apply the lens correction in the Develop pane.  Although the Library correctly shows the meta data for the lens and camera, the Lens Correction section in Develop does not even list that lenses LCP file in the drop down menu.  Instead, LR attempts to apply a different lens profile which does not match the focal length of the zoom.  I'm wondering if the LCP file that I created will only work on a Windows PC since that is where it was created?  What other explanation could there be for this problem?  Thanks for any advice...

    Update - I stayed up late last night and re-ran the lens profile creator at home on my Mac OS X 10.8.5.  Placed that LCP file in the directory I originally mentioned above (I overwrote the earlier LCP file created on a Windows machine), launched LR 5.3, and LR successfully matched the new profile with my lens.
    Lesson learned - an LCP file created on Windows OS cannot be used on a Mac, and I assume, vice versa.  In retrospect, this shouldn't be a surprise (but some other file formats appear to work on either).  I wonder if Adobe translates user submitted LCP files from one platform to the other, so that downloads are offered to the community equally on either platform...

  • Help with creating a lens profile

    I am looking to create a lens profile but have a question about the instructions.
    Do I use the same size chart for all the focus distance shots?
    It is a wide angle lens with quite a close focusing distance.
    If I shot with the same chart at 1x, 2x and 5x the minimum focus distance as instructed, then if I pick a chart that works at 1x (i.e. fills 1/2 to a 1/4 the frame), then it is tiny at 5x, and doesn't fill the frame anywhere near the same as at 1x of course.
    Am I meant to use a bigger chart? Or start the 1x with a very small one?
    Thanks for any help.
