Stange colours - Sony A700 - cRAW to 8 bit Tiff
Dear P1 team
hi all,
as the support for the Sony A700 was included into C1 4.01 I decided to download and buy the program. Before I tested both Beta versions with A100 files and KM 7D / A2 files.
Now the conversion of A700's cRAW files to 8bit Tiff files have lead to some strange results, as there appear (visibly) larger or smaller all-pink or all-yellow areas in the images - where I suppose some highlight clipping may have occured. But from my point of view it's unacceptable that C1 4.01 "ADDS" colour by its own. The coloured areas were visible on the screen when processing the files but I thought they were some clipping warning. I didn't imagine that these colours would be visible too in the converted images.
Besides these areas I found too single coloured/white pixels (blue, red, white) in dark/black areas of images taken under low light conditions.
I would like to know if these observations are results of some bug or what else is the reason. Is there any restriction using cRAW instead of RAW?
If you need images for further examination please contact me or post here a reply how to post/send examples.
Cheers,
Michael Fritzen

PhaseOne said that cRAW Files are not supported.
If this will change in the future? Don't ask me...
The cRAW algorithms are different and PhaseOne do not know how exactly to handle this because SONY is not given enough information. That's what PhaseOne said.
e.g. DCRAW is capable to handle these differences about which SONY is not talking, so there is hope that PhaseOne will find a solution for this problem, hopefully.
Until this will happen the only "workaround" for you is to shoot in RAW.0
