Lens Profile File Format

Is there any possibility that the format of the lens profile files will be documented?

It is an XML format. The format is documented here http://download.macromedia.com/pub/labs/lensprofile_creator/lensprofile_creator_cameramode l.pdf.

Lost lens profiles in LR 4-5

Recently Lightroom no longer finds my lens profile (sigma 17-50mm) on new pictures. Same camera, same lens, same file format. It can still use the profile on older pictures but newer pictures it only shows like 5 lens profiles vs the 50+ that were there before. Similiar behavior on the canon side. By the way it seems to have lost the ability to see many other lens manufacturers to on the newer pictures.
So I know the profiles are physically on the system. I know I can see them in older pictures just not newer ones on the same library. No update I can think of correlates to the change either.
Canon 60D jpg & raw, Sigma 17-50mm f2.8
Lightroom 4 and now also the new lightroom 5.
Thoughts ?

Oh I should have known better...yes it was. Why that didn't jump out at me I don't know.
I modified the RAW profile for jpg and dropped it in
C:\Users\[username]\AppData\Roaming\Adobe\CameraRaw\LensProfiles\1.0\Downloaded,
and I am off to the races.

How to Set Lens Profiles on a tone mapped HDR

I'm trying to work out the optimal workflow for doing HDR (using HDR EFEX 2) on a set of images.
I can apply LR's Lens Correction (Nikon, 17-55mm F2,8) and chromatic aberation removal on the whole set set (using LR Sync) before I export to HDR - then turn off the Chromatic Aberation fix in HDR - and that gives me one workflow.
However, that makes a lot of changes to the TIF's before I go in - so I am wondering if it would be better to export the RAW files converted to TIF using minimal changes from LR e,g, no CA fix or Lens Profile correction; let the HDR do its thing and then make profile corrections, Upright, etc upon return from HDR. However, when I get back from HDR and go into Develop with the returned file and go to Lens Correction, I cannot chose the 17-55mm F2.8 lens from the drop downs. There are only about 4 or 5 lenses now showing as Nikon possibilities-and the 17-55 is NOT among them.
How come I don't still see the full list of Nikon profiles - shoudln't I be able to apply any profile to a TIF (even an incorrect one) ?
I tried pasting the Develop Settings from a virtual copy where I had set the Lens Profile to 17-55 F2.8 - but that only turns on the Lens Profile 'filter' and does not actually force-on the specific correction.
Any thoughts ?

Since lens profiles are format-specific, is that the source of your problem?

Lens Profiles listed as available, but missing in lr4

Hello,
the lens profile of my Samsung 12-24mm F4-5.6 ED is listed by Adobe.
It still does not appear in Lightroom 4.4 (french version).
I shot with a NX300, only Raw Format.
I'll be thankfull for any help.

What is your source of the information that the 12-24 is supported by Adobe? Adobe supporting the raw format of the camera is not the same as Adobe providing lens profiles for a particular camera. Of course, some cameras have lens-profiles build into LR that cannot be turned off, and these will not be listed as distinct profiles you can choose between, they are just always applied. Usually this situation is for point-and-shoot cameras that don’t have removable lenses, which your NX300 is not one of.
Searching the lens-profile files, themselves, that were installed by Adobe LR 4.4, LR 5 and PS/ACR 8.1, I can only find three Samsung NX lenses that have profiles from Adobe, all three for raw:
·         Samsung 18-55 f3.5-5.6 OIS
·         Samsung 30mm f2
·         Samsung 50-200mm f4-5.6 ED OIS

Help with importing lens profile to Lightroom 5.4 for Windows

Hi,
I'm running Adoble Lightroom 5.4 on Windows. I recently bought a Rokinon 14mm lens for Canon and have a couple lens profiles that I want to try out. I have already tried importing to the two following locations below and nothing showed up when I restarted Lightroom. Any solutions?@@
C: > Users > User > AppData > Roaming > Adobe > CameraRaw > LensProfiles > 1.0 > Then I created a folder called Downloaded > Then I created another folder inside the folder Downloaded called Rokinon and dropped the lens profiles in there.
Here is the other one I tried:
C: > Program Files > Adobe > Adobe Photoshop Lightroom 5.4 > Resources > LensProfiles > 1.0 > Then I created a folder called called Rokinon and dropped the lens profiles in there.

Something is weird about this lens profile file. It appears to be for a Canon 85mm lens, not a Samyang 14mm lens, and, as you say, this profile is for JPG files not RAW files. If you want it to apply to raw files you need to change the CameraRawProfile from False to True.
After changing the False to True, because the Make is set to Canon you have to go to the Canon lens list not the Samyang list in the Lens Profile selection dropdown list, or edit the Make to have Samyang..
Because there is an 85 for several focal-length numbers, not 14, I think the correction being applied may be totally wrong. Where did you get this lens profile file? The other profile file you sent has 50mm in some focal-length areas and 85 in others.
To be able to tell if this, or the other profile, is reasonable, you probably need to take a picture of something with a grid of lines, like a brick wall and see if there is barrel or pincushion distortion that is corrected or worsened.
Here is a screencapture of the file as it looks in a text editor with notes about what seems wrong:

Missing Canon lens profile into lightroom

Hi Guys
I have LR4.1 and I just realized that I am missing the one for my 100-400 f4,5/5,6
any idea how can I get it ?
Many thanks
have a super day, Thierry

It is possible to save a duplicate of the lens profile file, and "kludge" it from Raw to non-Raw using a text editor. This generally works well enough; much better than manual corrections alone - provided that the camera is not also applying lens correction, and so confusing matters.

Decision-making process EXIF = correct lens profile

I created a lens profile for my new camera Sony SLT-A77 with lens SAL-1680Z.
I use ACR 6.6 with activated feature "Enable Lens Profile Corrections" and Setup = Auto.
My new profile is found automatically because of EXIF information in the DNG file
and matching tags in the lens profile file.
EXIF:Make = stCamera:Make = "SONY"
EXIF:Model = stCamera:Model = "SLT-A77V"
EXIF:Model = stCamera:CameraPrettyName = "SLT-A77V"
EXIF:LensModel = stCamera:LensPrettyName = "DT 16-80mm F3.5-4.5 ZA"
But my problems start with the second lens. This is Tamron SP 70-300mm.
There is a lens profile provided by ACR 6.5: "SONY (TAMRON SP 70-300mm F4-5.6 Di USD A005S) - RAW.lcp"
But the tags in this file aren´t matching the EXIF in my DNG files.
So I tried to edit the tags like in my own lens profile.
EXIF:Make = stCamera:Make = "SONY"
EXIF:Model = stCamera:Model = "SLT-A77V"
EXIF:Model = stCamera:CameraPrettyName = "SLT-A77V"
EXIF:LensModel = stCamera:LensPrettyName = "TAMRON SP 70-300mm F4-5.6 Di USD A005S"
But in ACR6.5 this profile isn´t found automatically. I have to choose manually
in the Lens Profle menu the Make selector. But I have to choose "Tamron".
I can´t understand this behavior because the tag is stCamera:Make="SONY" and
there is no tag with "Tamron" in the profile.
I deleted all other lens profiles on the computer to exclude problems with another lens profile.
In the document "Adobe Camera Model V1.0" on page 11 I found the required EXIF tags,
but I suspect the mechanism ACR choose a lens profile is different.
Ingo

There is also a LensID field in xmp:aux that would affect the lens matching. Bring your photos in PS/Bridge, show the FileInfo dialog, go to the Advanced panel, you can tweak the metadata in the lens profile to match the same values shown in the FileInfo dialog.

Lens Profile Downloader ?

I have downloaded subject and companion programme AIR. Selected my 24-70 ZA lens and downloader says installed. Yet when I load up LR (3.5) the new lens does not show in the Sony le s profiles just the same old 4 lens that LR comes with. What is going on?

I'm not at all familiar with your camera. But are you aware that lens profiles are format specific? In other words, a profile created for working with JPEG images will not work on raw images, and vice versa. Does that impact you in this situation?

Why the lens profile list can't show ALL lens profiles items from "LensProfiles 1.0" folder?

When I add a new lens profile - Samyang 14mm f2.8 - .lcp file into the "LensProfiles > 1.0" folder, I appear there are many lens profile items can't show in the Lightroom lens profiles list.
Please tell me how can I add these items into the LR lens profiles list........... thanks!!!

Sorry my bad, should have put.
Your custom Camera Raw & Lens Profiles should be installed to the User folders…
Lightroom 5 no longer uses the shared ProgramData (Windows) / Application Support (Mac) folders for Camera or Lens Profiles. Instead, it stores the built-in profiles with its program files.
When you create camera or lens profiles, they must be stored in the user locations listed below. If you previously stored custom profiles in other locations, you’ll need to move them to these user folders, otherwise Lightroom won’t be able to find them.
Windows—C: \ Users \ [your username] \ AppData \ Roaming \ Adobe \ CameraRaw \ CameraProfiles \
Mac—Macintosh HD / Users / [your username] / Library / Application Support / Adobe / CameraRaw / CameraProfiles /
For the lens profiles, substitute the LensProfiles folder for the CameraProfiles folder.
The camera and lens profile file extensions are:
.dcpr—camera profile recipe file used for creating/editing a profile in the DNG Profile Editor
.dcp—camera profile
.lcp—lens profile

Lens profile for the Canon 24-70 II?

There isn't any Lens Profile available for download for the new 24-70 II and the 5D III.
Has anyone used the profile for the Mark I? And, how long before new profiles usually show up at the Adobe site?
Thanks
Mark

It's now in the LR 4.3 release candidate
I installed the release candidate on a separate PC, found the lens profile file in the install folder and copied tge file to the appropriate folder in my 4.2 install.

Lens Profile: ACR 8.8 to LR 5.7.1

Dear All,
Adobe has made my year by including a lens profile in Camera Raw 8.8 for the Nikon Ai-S 50mm f/1.2 (thank you Adobe!)
Greedy as ever though, I'd like to be able to use this profile in Lightroom so I do not need to invoke Bridge or Photoshop.
Is there a file I can copy from a to b, or is it built-in and inaccessible?
I imagine it will be included in Lightroom 6 anyway, but of course there are no guarantees and we are all impatient (some more than others, clearly).
Many thanks.

To use a new lens profile provided by ACR 8.8 or the DNG Converter 8.8 (if you don’t have Photoshop) prior to a LR 5.8 or LR 6, you can copy the appropriate lens-specific .lcp file to your users profile area.
The Lens Profile Downloader will only download third party profiles but not ones that are supplied as formal updates so if Adobe has actually provided a profile it’s usually best to use theirs.
On Windows, the profiles that come with ACR and the DNGC are located in the manufacturer subfolder under:
C:\ProgramData\Adobe\CameraRaw\LensProfiles\1.0
You find the appropriate .lcp file and copy it to your user’s profile folder, which on Windows is here:
C:\Users\YourUserName\AppData\Roaming\Adobe\CameraRaw\LensProfiles\1.0\Downloaded
The default on Windows is to hide the ProgramData and AppData folders in Explorer so you can either change the options to unhide them or just type in the name in the Explorer address area and hit Enter then continue clicking down into the path further.
On a Mac I’m less sure where the ACR and DNGC installers put lens profile files, so I cannot say where to get them from, but if you find them, you can put them this folder that the Lightroom Queen’s indicates:
Macintosh HD / Users / your username / Library / Application Support / Adobe / CameraRaw / CameraProfiles /

Conversion of downloaded lens profiles

Hi,
I have a Canon EOS 500D with an ef-s18-135mm f/3.5-5.6 is lens.
I found a lens profile for a Canon EOS 7D in the Lens Profile Downloader.
Can I use/convert this profile for my Camera?
Is there a way to use this profile, which is created for RAW images, for JPEG images?
thanks!
Peter

The transformations specified in a lens-profile file are resolution independent and it is generally ok to apply a lens profile for a specific lens on one camera to the same model lens on another camera as long as you're not using a crop-sensor-camera profile with a full-sensor-camera image.

LR lens profile for Nikon P7000?

I cannot find a profile in LR 3.3 for the Nikon P7000. The P6000 comes up, but no P7000. 3.3 supports the NRW files from the P7000. Can anyone give me a hand?
Thanks very much . .
Jack

Your computer has the same operating system as mine so there shouldn't be an issue with file paths being different for that reason.
You should only see the P7000 lens profile when you edit RAW/NRW files, not JPGs. Please confirm that when editing an NRW from a P7000 you cannot locate a "NIKON COOLPIX P7000" profile in the list (at the bottom of about 50 Nikon profiles) when Nikon is selected as the "Make". Also confirm you do see a screen-full of profiles, not just one or two. Do this in LR 3.4 RC.
Please locate the P6000 lens-profile (.lcp) files that you can see in the list on your hard drive using Windows Explorer and the paths given, earlier. If you can't find them, please be specific about what part of the path does not work or what part of the process doesn't work. If you don't understand some part of these instructions for locating the lens-profile files, say what part. Saying you cannot find them is not enough information. By locating the Nikon lens profiles we can verify if the file are missing or if something else is wrong. I would also like to see the dates of the profile files to understand how long ago they were installed.
You should be using the start-menu/start-button and opening Computer (or My Computer), then copy-pasting each path, in turn, to the address area and hitting Enter or perhaps click on the right-arrow at the right end of the address area. If copy-pasting the full path in the address area doesn't work, try part of it and add the foldernames one-by-one until you can't get to part of it and say what part that is.

Correct Lens Profile Not Available for Exported/Imported Image Files

Any help with this would be appreciated. I just noticed yesterday that when I have RAW (DNG) files in my LR5.2 library, I can select the correct lens profile to apply. When I take three of those files and merge them together in Photomatix Pro they come back as a single TIFF file. Now LR only has one lens profile available, and it is the wrong one.
This is happening with my Sony NEX-7 and Tamron 18-200mm f/3.5-6.3 XR DI-III VC. With the RAW files, I have a list of Tamron lenses from which to choose, and the correct one is available. For the merged TIFF file, however, only a single Tamron lens is available for selection, and it is not the lens I used.
If anyone has any ideas about this and can get me past it, I would greatly appreciate it.
Thanks,
~Steve

Here's my workflow for this particular situation: After importing the original RAW files, I apply lens correction using the correct profile. I export to another application that creates a new (TIFF) file that comes back into LR. Even though I already applied the correction to the original files, I can see that there is a difference in distortion between the original files and the new TIFF.
If your other application is opening the Raw file directly, it will likely be disregarding either most, or all, Lightroom adjustments even if they are somehow communicated to it. It will come down to whatever independent Raw support is built into the other application.
The other application would still need to (a) "understand" about Adobe lens profiles etc, (b) "know" where to find the appropriate Adobe profile on disk, and (c) be equipped to do the specific and proprietary processing that they refer to. The same applies for all the other Adobe-proprietary processing instructions. The only software I am aware of which can do all this reliably, in partnership with LR, is Adobe Camera Raw plus Photoshop.
I've trained myself that whenever a new file is created in an application outside of LR (including PS), I always re-apply lens correction upon first returning to LR. If I'm interpreting the above responses correctly, I shouldn't need to re-apply lens correction if I applied it to the original files. But again, it's not my observation that this is the case.
If your particular workflow is failing to reflect the first application of lens corrections (as well as perhaps, other specific adjustments) - then what returns to LR will not have undergone those kinds of corrections yet.
I'm also hearing that I may need to download a lens profile for this lens for a TIFF file format. I've never needed to do that before, so perhaps I'll give that a shot.
As I understand it, Photomatix can also accept converted TIFFs or JPGs from LR - instead of Raw fles. I am skeptical that you will realise any "clear water" advantage from sending Raws rather than TIFF (or even, high quality JPG in many cases) from LR into Photomatix - assuming the LR conversion is already optimising the images for the required purpose. You would be doing that step in an interactive environment rather than blindly via a generic converter. Such intermediate bitmaps are in my experience perfectly good candidates for HDR processing, or for exposure fusion (which I prefer - though I don't use Photomatix in particular).
Any workflow which causes LR to in effect Export suitable bitmaps that incorporate all current adjustments, will embody lens corrections as part of that. By the way, the workflow into Photoshop HDR is similarly done by way of converted bitmaps - though in that case it is ACR rather than LR which achieves these converted bitmaps, and into memory rather than into separately saved files, but the outcome is effectively the same.
The only downside is the "cleanup" is to get rid of intermediate TIFFS or JPGs afterwards. I usually put the completed "merged" image at the top of a "stack" containing the component exposures, and collapse the stack down. But the (disposable) intermediates don't get imported to LR, and by setting these to occur in a subfolder or with a distinctive name suffix, they are easily found and deleted in due course.

Why would Adobe's Lens Profile Creator distribute the checkboards as JPG files?

Generall, JPG files are a bad idea for images that contain a small number of colors (poor compression) and sharp edges (ringing artifacts). So why then would Adobe distribute the checkboards for Lens Profile Creator as JPG, rather than some more appropriate format such as PNG?
Chuck

The jpgs are samples of what one might get when one took pictures of the checkerboards. The actual checkerboards are indeed PDFs. It will be interesting to disect the PDFs to see what the graphics are. The really right thing would be vector.
