Hi Fletcher,

I played with it in the last 2 days and made a de-fish profile for the Pentax 10-17mm.

You'll need the Lens Profile Creator: http://labs.adobe.com/technologies/lensprofile_creator/

Print out a few charts, set up lights & your tripod and shoot a few pictures at different distances, angles, focal lengths and so on...
The software then creates the profile based on that (an extensive how-to is included in the free download from Adobe Labs!)

From what I've read, Adobe is working on a central database for users to submit profiles!

Until then, feel free to download my profile here: http://www.attilaacs.com/downloads/pentax_lens_profiles/pentax_fisheye_profile.z...

The main problem I see is that all camera and lens combinations are needed. Not just one profile for a certain lens but also the same lens along with another body...

As for manual tweaking: I haven't had ANY luck using the manual controls without the profile I created. De-fishing never worked for me on the wide end of the fisheye lens. Until now!

Thanks everyone

@mecrox: Thanks for the tip, I'll have a look at the group! I did join a while ago but I'm not too good on keeping up with all the stuff that's happening on flickr.

I think if you want to limit the downloadability a bit further, you might be better off choosing a Flash based gallery. Personally I'm not a fan of those but they just make it a bit harder to grab your images off the site.

If you have Lightroom you could have a look at the Flash galleries that are built in there. They have tons of options as well.

http://slideshowpro.net is a pretty good one too and I think they have a version where you dont need lightroom...

Hi, I joined a little while ago but was mainly reading things. Just thought I'd say hi and quickly introduce myself:

I'm Attila and I'm a design person currently living in Oxford, UK. I'm doing my second 365 project now which can be found on my flickr: http://www.flickr.com/photos/attilaacs
And here's a collection of my personal favs: http://www.attilaacs.com/portfolio/photography/

This is my gear right now: K200D, Pentax 17-70, Pentax 10-17 Fisheye, Pentax 100mm DFA Macro, Pentax 18-55, Pentax 50mm M 1.7, Metz 48 Flash and a few minutes ago I ordered a Pentax 21mm Limited which I'm very excited about!

Hope to hang around here for a while. It sure is very helpful to read all your posts and hopefully I'll be able to contribute a bit as well

cya
