On second thought I don't get it. In the trial version the file formats I have an option for are PSD (supports layers), TIFF (no layer support) and JPEG (no layer support). PSD does not save a viewable photo without a device, which leaves the choice of TIFF or JPEG. Does the Color Space setting play a roll in this? Paul
I'm confused. What is it you're trying to do, exactly? I mean, if you're not using Photoshop to process, I'm unclear on why you care about saving to PSD? And no, your choice of color space doesn't have anything to do with this.
You have a RAW file, which is not an image file, it's a data-file used to create an image file (and color is a function of the output device, but that's really not relevant here). Once you're done processing your RAW file, and assuming you want to save it as an image-file, then it needs to be converted to an image-file format and Perfect Effects is giving you some choices for how you do that: You can save your RAW as a TIFF, an uncompressed image-file format or you can save it as a JPG, a compressed image-file format or as a PSD which is a kind of proprietary format used by Phototshop that preserves your work in stages, for lack of a better way to put it. But since you don't have Photoshop this option shouldn't really be of any concern to you.
Maybe you're confused that you can't save your RAW files as a RAW file? If that's the case that's because, again, a RAW file is data; it's the digital information, the 1's and 0's your digital camera captured. It's not a "picture" yet, it only becomes a picture when it's saved *as* a JPG or TIFF (for example). That's the conversion: from "raw" data to "picture"; from RAW to JPG (or TIFF).
