(posted 8361 days ago)Once a shot is Photoshopped, output is a bit of a problem
Why do you think so? The output of digital files is not restricted to inkjet printers. If you need an 8x10 or lower, find a lab with a Fuji Frontier system (or upload your images to e.g. www.shutterfly.com) and they will print your file on real photo paper.
If you need larger sizes, drum scan -> Photoshop -> Lightjet ouput is the way to go. It is fairly expensive, but considered to be the very best way, wet-chemistry or digital, to make big prints from slides. I suspect results from negatives will be as good (subject to the quality of the original, of course).
This is all regularly rehashed on regular photo.net forums, so a search there will provide loads of info.
