Hey everyone,
I appreciate all of the comments and input. Langier, I agree with what you said about the shadows looking somewhat muddy in photographs 1 and 3. However, the lighting on those particular scenes was what triggered me to take the shots in the first place. When I took photo 3 it was a very dark and overcast day, but then suddenly the light shone through onto the one hill that looks lightest in the photograph. Do you think I could have used exposure compensation to increase detail in the foreground?
Looking back at the histogram, I probably could have exposed to the right slightly more to increase detail in the shadow. But beyond that, do you have any suggestions for increasing detail in the foreground in dark lighting conditions, for example during a sunset like photograph 1?
As far as the cropping issue/changing the aspect ratio goes, I think photograph 1 is enhanced by the cropping. My camera shoots in 4x3 aspect ratio by default, which didn't really suit the scene in photo 1, where the interesting detail in the photo stretches horizontally...
Thanks to those with the editing suggestions. Dwayne, I like what you did with image 1, although I might go for a more subtle enhancement, and I agree the snow patch is something of a distraction. Image 3 I like J Berardi's take, although I think if I had photoshop I would try a luminosity mask on the foreground area to lighten it up a touch more.
Dick, your suggestions for 1 and 3 proved dead on, and when I went back into the editing software Canon provides (very limited), changed the white balance and was pleased with the result.
Hopefully pretty soon I will have some decent processing software, and I'll be able to take the next step in the game.
Cheers,
Brent
