Mr_Jones Posted March 21, 2011 Share #1 Â Posted March 21, 2011 Advertisement (gone after registration) I have made a lens profile for my X1 using the adobe software. It's hard to tell how scientific the results are as it all seems a bit diy, but the images please me. Â If you would like to make one, search for lens profile creator and you should find the adobe software. Â The process is quite simple. Â download software and files print sheet of squares photograph squares in 9 positions (straight, tilted down, tilted up, left straight/tilted etc.) load dng's to software set checkerboard info (measure screen dimension in pixels of smallest square using ruler in tool bar) generate profile. Â Not childs play but the results I get are interesting. Link to post Share on other sites More sharing options...

JeTexas Posted March 21, 2011 Share #4 Â Posted March 21, 2011 The X1 has an embedded lens profile -- at least it does in Adobe RAW CS4 and CS5. Link to post Share on other sites More sharing options...
barjohn Posted March 21, 2011 Share #5 Â Posted March 21, 2011 You need to shoot something that would allow us to tell the effect. Other than possible exposure difference I can't see any real difference in your two images. Link to post Share on other sites More sharing options...

Mr_Jones Posted March 21, 2011 Author Share #7 Â Posted March 21, 2011 Advertisement (gone after registration) Which is which? Â Original then altered, the differences are not that small. Also applying the lens profile is the only difference. Link to post Share on other sites More sharing options...
Mr_Jones Posted March 21, 2011 Author Share #8 Â Posted March 21, 2011 The X1 has an embedded lens profile -- at least it does in Adobe RAW CS4 and CS5. Â Talking about LR3, I would be surprised if they had an embedded lens profile in CS4/5 but didn't supply it as an option in LR3. I know from some other threads that you don't use LR3 though, there is a section called lens corrections which offers corrections for many popular lenses.

Other than possible exposure difference I can't see any real difference in your two images. Â Neither can I. Â Mr_Jones, you're not obliged to do anything, but if you want people to comment on a profile, you need to show an example where it's a bit more obvious what has changed, in my view.

Mr_Jones Posted March 21, 2011 Author Share #10  Posted March 21, 2011 Neither can I. Mr_Jones, you're not obliged to do anything, but if you want people to comment on a profile, you need to show an example where it's a bit more obvious what has changed, in my view.  The effect is quite subtle, but if you are able to switch between the two using the check box in LR3 you notice it immediately. I'm sharing a technique which answers a question I've seen raised in the forum. I'm sorry to say the effect is subtle so if you don't notice it, move on, nothing to see here.....

andybarton Posted March 21, 2011 Share #11 Â Posted March 21, 2011 I don't use LR3, but looked at both in Photoshop. Â Sorry I couldn't see anything, apart from the exposure. Link to post Share on other sites More sharing options...
h00ligan Posted March 21, 2011 Share #12 Â Posted March 21, 2011 Mr_Jones, Â You offered something up that could be of greate interest but then been rude and shot down two requests to show more tangible results. Â It's like you wanted to help others..but then felt insulted (which I don't think ws anyone's intention) Link to post Share on other sites More sharing options...
Mr_Jones Posted March 21, 2011 Author Share #13 Â Posted March 21, 2011 No need for psycho-therapy, I've offered the pictures as a second thought. The important thing is you can build a lens correction profile yourself if you wish. Â What Andy and John are overlooking is the process of lens correction can affect the appearance of the exposure, which they've both indicated they think is different. I'm not shooting anyone down, but the differences are subtle. Â Look at the branch in the top left corner there is quite a difference in the position it intersects the edge. The haze from the sun is lessened. When you see the image correction in LR3 you can easily see the adjustment of distortion. Instead of placing the images side by side you need to flip between them. Â I would say I am being helpful by pointing out the potential to create these profiles for LR3 users, but again if you don't use LR3 there's not much value in this thread, and if you can't see the differences in the two images you're not looking at them closely enough. Â As an example if you have pictures shot with a different camera (Nikon, Canon etc.) try the lens profile feature of LR3 and you will see the difference I'm talking about. You can't try it with Leica bodies or lenses as Adobe do not supply them (subject of another conversation). Â In short the X1 lens can suffer a bit of correction unsurprisingly since almost every lens in the world can use a bit of correction. Link to post Share on other sites More sharing options...

h00ligan Posted March 22, 2011 Share #15 Â Posted March 22, 2011 Ok, so the pictures were a second thought, you were posting to point out one could build a lens correction profile. Â Welcome to lightroom I guess. Â I can't think of many lightroom users who don't know that. Link to post Share on other sites More sharing options...
Mr_Jones Posted March 22, 2011 Author Share #16 Â Posted March 22, 2011 There was thread discussing LR3 lens profiles and Leicas' absence from the list called http://www.l-camera-forum.com/leica-forum/digital-post-processing-forum/170796-lens-profiles-leica-lenses.html in the digital post processing forum. No one mentioned the fact that you could make your own. So it seems I'm not alone in my ignorance anyway Link to post Share on other sites More sharing options...
h00ligan Posted March 22, 2011 Share #17 Â Posted March 22, 2011 You know you can do the same for colour profiles as well, correct? Link to post Share on other sites More sharing options...
