Hi There - I wonder - is it because with the older files there was no camera support for the Ricoh, and that Apple have actually changed that support with the new update?
Does that fit the bill?
Thanks for the answer. It may well be some element of this transition that's causing the problem. But I can't figure out what and why? Previously I had to hack the plist file, and then the dng conversion was used. However, it is the old files that are untouched. It's only the recent incremental upgrade, causing problems with files that were originally converted with dng 2.0 .
The one new theory I have is that it may have to do with me changing from auto WB to manually selected WB when shooting, in order to get more consistent color. This is something that roughly coincides with the affected files.
I have one question re: this - not directly related to the conversion problems. Selecting any particular option eg: cloudy, doesn't seem to completely determine the WB, in the sense that the temp. and tint values are not the same for all photos taken with the same setting; the camera seems to be making some "intelligent" deviations from the mean. Is this the case with all cameras, or is it ricoh specific?
Man, that is frustrating! If you were running a MAC with Time Machine active, I'd suggest you revert to the system status that existed just prior to loading the recent Aperture update. If you're on Windows, then that's not much help.
Have you checked all the default settings for import? Do you still have your original RAWS stored separately? I suppose it's possible (although a pita) to tweak your default settings and then re-import the files being effected. Or are the effected files versions that have been edited to something other than RAW (i.e., .tif)? If so, maybe it has something to do with the way it's rendering tiffs. Colorspace? Gamma? Just chucking things out here. Wish I could help. Good luck.
Unfortunately, it's the raws. Tifs & jpgs are untouched. I've thought of the colorspace issues, gamma, accidently turning on soft proofing, but this can't be the case since the problems are not with all, just some raws.
I have thought of reverting to the backup. The problem is that I'd also have to revert to the old version of aperture, and probably of the raw conversion files, which are system files. Which means I'm likely to get into an even nastier mess in the future. (I don't unfortunately keep everything on Time Machine, just the home directory).
I usually keep all the versions when editing photos. If I'm done editing something one day, I'll continue the next day by continuing from a copy. This helps me remember the thoughts I had as to why I should edit one photo this way or that way. The re-rendering messes my way of doing things in a significant way.
Anyway, thanks for the answers. It's great to get some new ideas.
