should i save my pictures as Tiff or PSD or is there a better choice.
Just bought a Nikon D70 and took a few shots using Raw
First, of course, keep your original raw files. Those are basically your digital negatives, so you can always go back to them if you need. Both TIFF and PSD formats are "lossless" in the sense that they retain all the image information that results from converting the raw format. If you are concerned that time will pass, and you will lose the ability to read the original raw files, you may want to also convert the raw file to TIFF or PSD and save a copy before you make any adjustments. For this purpose, TIFF may be a better option as it is a standard format.
I always use PSD files for my "working" images. I can’t think of any advantages of using TIFF except perhaps easier interchange with other programs. I wouldn’t be surprised if the PSD format can store things not stored in TIFF files. Something sticks in my mind about TIFF not storing alpha channels. I’m sure someone here can confirm or deny this.
