Adobe lens profiles for Camera Raw, Photoshop CS5, Lightroom 3
Posted By: knoxploration, 08-30-2010, 11:31 PM

Photographers using current versions of Adobe software including Camera Raw 6.1 or later, Photoshop CS5, and Photoshop Lightroom 3 all have a useful tool at their disposal, which can correct for geometric distortion (both barrel and pincushion), chromatic aberration, and lens vignetting -- all with a minimum of fuss. The feature relies on lens profiles, which can be created by the user community. (Adobe themselves also provide a modest number of lens profiles.)

The process of creating a lens profile has been designed to be relatively straightforward, and is achieved using a free Lens Profile Creator tool available from Adobe Labs. (Full instructions are available from Adobe in their Lens Profile Creator Calibration Chart Shooting Quick Start Guide, as well as the full Calibration Chart Shooting Guide, and are beyond the scope of this article.)

While the highest-quality corrections are likely to be achieved with a profile created using your specific camera model (and indeed, your specific lens units so as to cancel out sample variations), very acceptable results can be achieved with profiles created by your fellow photographers -- even if the precise camera model differs. Profiles are specific to either Raw or developed (JPEG, etc.) files, since developed files may already have lens corrections applied to them by the camera or other processing software.

And so, the purpose of this article: to help Pentax photographers share their lens profiles, and to summarize the available profiles. Following at the end of this post is a list of known profiles for first-party and third-party lenses on Pentax camera bodies.

If you have created a profile you'd like to share, or know of somebody who has shared a profile that isn't on our list, please either contact me privately to let me know, or simply reply to this article. I'll do my best to keep the first post in the thread updated with links to the latest profiles. (If you could let me know if I have your permission to add the profile directly as an attachment to this post, that'd be helpful. So would any information on how the profile was created -- body, focal lengths, apertures used, focus distances, and whether the profile is for Raw or developed images. If you know of profiles on other sites, please don't upload somebody else's profile here without their permission -- either provide a link to the site, ask them to join and share the profile here themselves, or both.)

Even if a profile already exists, don't feel shy about submitting your own alternative profile. There's a lot of leeway in profile creation, such as for example the number of focal lengths, apertures, etc. that are included in each specific profile. Adobe's software is designed to interpolate (read: guess) how lens characteristics vary between these user-defined sample points, and so profile creation is a balance between the accuracy of the profile, and the work involved in its creation. Lens sample variation also plays a part, and so do personal user tastes. It's possible that many users may find your alternate profile more to their tastes than an already existing one... :-)

(Note: For now, I've not had a moment to ask for permission from anybody to share their profiles as attachments directly in this article, so for the time being this list consists solely of links to other posts where profiles have been shared.)

(Edit: Still to do: Tidy up the formatting, add info on where to put the profiles for different apps / operating systems, include direct links to zipped attachments and request permission from profile authors to re-upload their profiles where they're not already zipped. *Phew!*) ;-)

Thanks, Bert. I've added this to the list in the first post. By any chance, can you tell me which focal lengths, apertures, and focus distances you used in creating this profile?

Updated DA*60-250mm profile.

Now, in this file I edited the XTML for the lens information manually.

The old file works, however, since Adobe software has problems getting the DA 15 and the DA* 60-250 lens info out of the EXIF data, I had to do this manually.
This looks much better/consistent, when bringing up the Pentax selection table in LR.

Here is another Adobe Lens Creator profile generated from my new DA*16-50 zoom lens on a K-7 body (raw). FWIW, I compared the results to PTlens and found that geometric distortion correction was almost identical but vignetting and CA were much better corrected in my version which was a pleasant surprise since I like PTlens a lot.

Thanks, wjax! I've added it to the list. Any info on focal lengths, apertures, or focus distances used in creating the profile?

Oh yes, sorry, I shot an entire series at six evenly spaced focal lengths (16mm-50mm) X 4 spaced aperatures from F2.8 to F11 for a total of 24 image sets with 9-12 images in each. Then I added a second longer focal distance series at 16mm, 33mm, and 50mm X 4 equally spaced apertures from F2.8-F11 as above for another 12 image sets. I did not go above F11 on any series, per adobe's instructions. I used a 27X39 grid printed on letter sized paper. It was lots of work but I am very happy with the results and I am glad to share here.

I plan to do another lens calibration with the DA* 60-250mm and compare it to PTlens as well. I will upload it here if it comes out anywhere near as well as the 16-50mm series did.

Oh yes, sorry, I shot an entire series at six evenly spaced focal lengths (16mm-50mm) X 4 spaced aperatures from F2.8 to F11 for a total of 24 image sets with 9-12 images in each. Then I added a second longer focal distance series at 16mm, 33mm, and 50mm X 4 equally spaced apertures from F2.8-F11 as above for another 12 image sets. I did not go above F11 on any series, per adobe's instructions. I used a 27X39 grid printed on letter sized paper. It was lots of work but I am very happy with the results and I am glad to share here.
Great, thanks! I'm sure your fellow Pentaxians who have access to that lens will appreciate the effort. I've integrated this information into the list in the first post.

I plan to do another lens calibration with the DA* 60-250mm and compare it to PTlens as well. I will upload it here if it comes out anywhere near as well as the 16-50mm series did.
I'll look forward to adding this too.

Ask and ye shall receive. I ran the same test vs. PTlens and, again, my profile does a better job with CA and vignetting but is virtually equal in correcting geometric distortion. The interesting thing here is that the author of PTlens created his profile for the DA*60-250mm lens from a custom set of my calibration photos (jpegs). I can only conclude that the adobe program does a better job (at least with vignetting and CA) but PTlens is still very good. Maybe it has to do with the fact that PTlens uses only one image set (single aperture, multiple focal lengths, jpegs) for calibration?

FWIW, the attached profile was done similar to the DA*16-50 except that I used 3 focal lengths (60, 170, and 250mm) X 4 apertures (4,5.6,8, and 11) X 2 focus distances = 24 raw image sets (5-16 images per set).
