On the theory that a pic is worth several words, this and the next image 
are a couple of shots using DOF/hyperfocal control to maintain both 
nearby and distant subjects in focus

Yes, I know the color balance is different on the two examples, as well 
as some other shots in the gallery. This gallery is still very much in 
process, and I haven't decided which look I want to go with.

Back when I took a lot of images in Yosemite in Spring, 2002, I scanned 
some of them and put them up in a web gallery. I've meant for ages to 
rescan those I did before and scan many I didn't do before.  A few days 
ago, I had occasion to look at what I had done before, for another use, 
- and realized both how little I knew then about scanning and PS and how 
much VueScan and PS have progressed in the meantime. One of the things 
I've learned since is not to rely on automated prints for evaluating 
which images will look good scanned.

So I started over again, scanning all 200+ frames on the rolls with 
Yosemite on them. Good idea too, if it kept me out of some questionable 
threads the last few days. :-)

I have since done icc color profiles of all the films used, so the 
colors should be rather accurate. So of course, on the earliest shots, I 
found the colors in late afternoon sunlight very warm, ok, and the skies 
odd looking, not so ok. So I've been experimenting between the color as 
shot and something more neutral. Fortunately, many of the images won't 
require any such evaluation. This, for example, has very little color 
anyway
