Although I have used Aperture for years, I now export to Photoshop quite often. With PS CC I now can use their Camera Raw as a filter if I wish, instead of conversion in Aperture.
The question I hadn't though about, when exporting to a application in Aperture I realize its exporting to file format, in my case TIFF. What I don't know is if during the export Aperture is applying any of its RAW conversion on that TIFF? In some cases, I want photoshop to process my RAW files. I do realize I can export a RAW file out of Aperture, but it wouldn't be directing to another application. I would have to open the application and import that RAW file from whatever folder I put it.
Any info you can share would be valuable.
