Is anything lost when you export from (Canon) RAW files to TIFF?
For context: I backup and archive my RAW files, and keep a separate (Aperture) library for exported JPEGs. So far my workflow has been in Aperture (edit the RAW, export to JPEG), and that's fine.
However, I really like what the DxO Optics Pro software does (where it improves sharpness, distortions and CAs on a lens by lens basis), but obviously you can't export a RAW file into Aperture. It needs to work on the RAW, so it's adding a step to the process, as it doesn't have the library or editing features of Aperture
I tried the DNG format, but get files sizes over 150MB! (Compared to 25MB RAWs)
It seems that TIFF is the best option, but will I loose things such as the ability to bump the exposure 2 or 3 stops? (More applicable to highlights/shadows, but I assume that's the same principle.)
Are there any other more subtle things I would loose for editing?
