Originally posted by BarryE But I've been told that they are TIFFs and not RAW files. As I don't have access to a PS camera I'm trying to understand if I would have RAW processing capability in ACR, rather than the lesser TIFF. I been told it's only tiff, via dcu. That's what I'm disappointed about.
Well, since ACR can not, so far, fix the moving parts in a scene there will be artifacts when in ACR unless a stationary subject. I think there is alot of info in the 16 bit TIFF exported from DCU since it is larger than the original RAW-PS file and when processing it in ACR I have alot of dynamic range to play with.
I tested an extremely underexposed image and came to the exact, more or less, as far as I can see, the same outcome comparing a PEF and the DCU exported TIFF.
I have found that the quality of the PS is much better i DCU and I tried to only use ACR but for now, I open in DCU, export to TIFF after setting sharpness to Fine and crank it up two notches. Then do my edit in ACR.
