p.1 #1 · Adding image to the edge....


In another thread I was asked for a little tutorial on how to add to the edge of an image to simulate a more generous crop:

She speaks!

Nice - learned I've been doing this the hard way all along.

Thanks - plan on doing a series? This series goes back for two years! And you never told us?

Viewing video dunes - when you darken with the exposure layer, why do you raise the gamma rather than reducing exposure? Is there a parallel for LR?

When brightening (dune video), why increase exposure rather than lower gamma?

I never have understood gamma, which I know you adjust often.

I believe they were all created and posted here in response to requests, but I admit I've not done anything to be orderly about them.

Take an image and try reducing exposure and compare the effect to bumping up the gamma. Lowering the exposure seems to make it look more dull, while bumping the gamma seems to make a crisper darkening. I suppose the technical reason is something about contrast change difference between the too methods with gamma raising and lowering contrast as well as darkening and lightening. When I want something brighter, I usually like the effect of raising the exposure. When I want something darker with increased contrast, I prefer to bump the gamma. Bottom line is I don't feel the need to intellectually understand how gamma works. I just try different ways until I develop an intuition about what the controls visually do and work from there. Occasionally I experiment when I'm unsure. It's quick and easy to undo if I don't like the effect. More play time!
