As a point of education, what would you say the differences are?
I am talking about BW digital prints that are printed in the photog's home. Some of these guys have some pretty fancy equipment, although it may not be anywhere near what can be done in a top of the line digital print lab these days. Of course, if I can't do digital in my home, I'm really not interested in it; that's the big draw for me.
As you mentioned, the paper itself can be a give away. There are many more varieties for digital prints.
I look at the highlights. Usually this is where I spot it. I don't exactly know how to describe it, but I can point it out. Digital has a different look, particularly in fine details in bright highlights. When I say digital, I mean a print from a file, whether it was shot on film and scanned or shot with a digital camera.
Then I look at the mid tones. Sometimes I'll find weird tonal separations (they almost remind me of solarization). I think these are from tweaking curves too much.
I find it much easier to spot the difference in BW prints, although I can use these same things with color images. More and more people are fooling me with the color digital print these days; maybe tomorrow the BWs will fool me too.
I'm in the darkroom printing several times a week, and spend hours scrutinizing my prints. When I see something interesting hanging on a wall somewhere, I tend to give it the same intense scrutiny. If I think a print is digital, I don't really care, I'm just always curious as to the photographers methods. Of course, as with anybody, I will identify a little more with a photog who uses similar techniques as I do.
