The stuff that looks like it came from a video game, the artificial reality look of HDR, where the colors look like they were just pasted onto the objects underneath them. For lack of composition skills a lot of younger photographers are just going for this over saturated maximum "pop'. Don't get me wrong, I loved the look of Velvia back in the day, but it still had a natural look to the colors where a lot of the stuff I see online or even what a lot of my customers were showing me had that video game look. I guess you just copy what you grow up with!

Yeah, most of that HDR is crap, for sure. I just don't see how anyone could consider that stuff any good looking. "Yeah baby, let's squash the hell out of the image so we can see everything in all it's distorted glory"! Ugh!
I am glad my mentors (real and/or virtual) were mostly from the classic "California School", Ansel, Edward (and sons), Morley Baer, Wynn Bullock, etc. Not to mention some lesser know greats, such as Frederick Evans, for one, and the aforementioned George Fiske, for two.
Velvia was a cool film, if a bit too saturated in the greens, but I do prefer good old Kodachrome 64 (I used some 25 too, but the differences were pretty minimal IME). For my personal work when I had my Canon F1n I rated the K64 at ISO 40 to get the best compromise between shadow and highlight detail; I always mounted the camera on a tripod and used my Pentax Digital Spot Meter, although the built-in meter (with the spot meter screen D in the finder was quite good on it's own). I used some Kodachrome 120 for a while, in a Plaubel Makina 67 (another very nice camera, along with it's wide angle version, too). Bruce Barnbaum was/is a big proponent of Echtachrome 64T for his color large format work, using an 85B on his lenses. This cut the contrast well to produce better Cibachromes from. Speaking of Cibachrome, one exhibit of Edward Weston's I saw back in the late '80s included some of the color work he did as a consultant to Kodak; these prints were Cibachromes made from Edwards', and Cole's 8x10 Kodachome transparencies. Those were a bit of a revelation, to me, as to color imagery. Almost a 3D quality to them.
