POKO Posted December 13, 2006 Author Share #22 Posted December 13, 2006 Hi, That's so strange! I just downloaded this version from the Phase One website. I just called one of my assistants and checked - he does not have the function on his version either - but he did remember that another photographer that he works with has that feature - and he shoots with a Phase back. I just can't believe that they would have two different versions of the full software package for the same platform... Per Link to post Share on other sites More sharing options...
dhoelscher Posted December 13, 2006 Share #23 Posted December 13, 2006 I see no "lens cast correction" popup, and when you click on a raw file as the documentation suggests, there is NO option to save a lens cast correction. DH Link to post Share on other sites More sharing options...
harmsr Posted December 13, 2006 Share #24 Posted December 13, 2006 I'm on a Mac also with C1 Pro 3.7.6 Is there someplace that I need to go to turn it on? Mine does not show that. Here is my screen shot. Link to post Share on other sites More sharing options...

I just can't believe that they would have two different versions of the full software package for the same platform... Per Per: Can you get this function to work with a M8 file? It may be tied to the file type, not the software version or whether the software came with a Phase One back. Link to post Share on other sites More sharing options...
dhoelscher Posted December 13, 2006 Share #26 Posted December 13, 2006 I'm on a Mac also with C1 Pro 3.7.6 Is there someplace that I need to go to turn it on? Mine does not show that. I suspect that if you have a serial number that corresponds to a registered purchaser of a Phase One digital back, then that feature is enabled. Either that, or there is some extra file or invisible setting that restricts the C1 Pro software if you're not a digital back user. To turn it on, you'd have to know how Phase One restricts their software features - and to "reverse engineer" that would be illegal in the US - violating the DMCA (Digital Millenium Copyright Act). So, unless Phase One would tell you how to turn it on, I'll bet we're all out of luck unless we own a Phase One digital back (a lot of cash just for this feature, I think!) bummer!

POKO Posted December 13, 2006 Author Share #27 Posted December 13, 2006 Advertisement (gone after registration) Hi. Well, that was a bit of a waste of time for everyone involved! Just spoke to my dealer and the feature is in fact locked to the file type. It is only available to Phase files. I only shoot with a Phase back and only have those files so I had nothing to check against. Sorry for the false hope... Per Link to post Share on other sites More sharing options...
dhoelscher Posted December 13, 2006 Share #28 Posted December 13, 2006 Thanks, Per. At least we know now. The funny thing is, we REALLY need this feature to correct cyan / vignetting casts in non-Leica lenses for which there are no close optical Leica equivalents. Fig nuts!!!

gravastar Posted December 13, 2006 Share #29 Posted December 13, 2006 I'm afraid so ... just found this: Phase One - Quote: "Note The third check box (Lens Cast Correction) will only be available if you are working with Phase One H 20, H 25, P 20 or P 25 captures. This is a calibration tool, which is especially useful when working with wide angle photography or on cameras with tilt and swing options. Check out the sections, “Calibrating fixed lenses” and Section 1.5, “Lens cast calibration with image stitching” for more details on lens cast calibration." Bob.

dhoelscher Posted December 13, 2006 Share #30 Posted December 13, 2006 10 points to Robert Stevens for guessing the truth first !!!! :D DH Link to post Share on other sites More sharing options...
robertwright Posted December 14, 2006 Share #31 Posted December 14, 2006 It sounds similar to what leaf capture has, you do what is called a "gain" where you place a diffuser over the lens and use a strobe to do 8 exposures which is used to map all the pixels on the chip. You can correct many things, exposure imbalance, for example if you have the back on a view camera you can correct vignetting from lens movements for example, also it gets rid of color casts and gets rid of dust. this sounds like a simple version of that functionality, and no, it is not in my version 3.7 pro either... In theory it would fix many problems, the issue is however, it is focal length specific, also aperture specific, and focus distance specific, at least on the leaf version of things. If you change the lens you have to change the associated gain. also if the focus moves radically, all the dust that was gained out comes back looking like donuts sort of.

stevme Posted December 14, 2006 Share #32 Posted December 14, 2006 Lets try that again including the image... I have a Mac and version 3.7.6 of C1 Pro, and the third icon to the left in your screen capture does not appear in my version. I only have (1) set capture as white balance and (2) automatic adjust. The icon to the right of automatic adjust, as shown in your capture, is missing in mine. C1 3.7.6, build 3028. Steve Link to post Share on other sites More sharing options...

DH My screen looks the same as that of David Hoelscher. I have 3.7.6 on the Mac. No third icon. .... Just caught up with all the posts. This would be an excellent feature if Leica could get it for us, since they are partnering with Phase One on the software. Link to post Share on other sites More sharing options...
dhoelscher Posted December 14, 2006 Share #34 Posted December 14, 2006 Just in from Phase One customer support: David, Correct, this tool is for Phase One Digital Backs when shooting on large format cameras using wide-angle lenses. Typically less than 60mm. Regards, PhaseONEsupport DH Link to post Share on other sites More sharing options...
Guest guy_mancuso Posted December 14, 2006 Share #35 Posted December 14, 2006 Bummer not spending 40 k just to get it either. Honestly i was baffled by this, been using it for 4 5 years and did not have a clue about that. i guess i know why now Link to post Share on other sites More sharing options...
rvaubel Posted December 14, 2006 Share #36 Posted December 14, 2006 I think the point is that Leica could easily provide this fix in software. I hope they don't try to claim it can't be done. Rex Link to post Share on other sites More sharing options...
