i had been using nikon nx, picture project. photoshop cs2. purchased new iMac, base model. nothing works, not even my scanner. have searched for suitable replacement. cannot afford a new photoshop at the moment. downloaded free elements, awful. capture nx2 without photoshop is an incomplete processing tool. don't believe aperture will be adequate. tried downloading lightroom. won't open up. i suppose it's incompatible as well. are there any programs similar to picture project? when i try processing in capture nx2 it will only choose images from iPhoto, and the only ones that open are jpg, tiff, & nef cannot be selected. processed an image in capturenx2 in jpg and compared to my usual; nx, photoshop, in raw/tiff/jpg it was awful. i'm having the other computer i had to use for a few years; windows, (1 gig ram) fixed and will probably have to use it. at least i can scan b&w negs, and process digital raw images. but the reason i purchased an iMac w/12 gig ram was to improve my workflow. i did now know about the xos lion. thanks for any assistance.
