Sharon,
Your comments about color changes brings up an important issue that isn't well known. Coincidentally, I was trading e-mails with someone about this when I saw your post.
When you adjust contrast in most ways, the software is acting on the three color channels, R, G, and B. E.g., if you impose an S-shaped curve to increase contrast, you are actually performing that action on each of the color channels. The result can be substantial shifts in color; the colors will seem more saturated, and the balance among colors may seem to shift.
If you use Lightroom, there is (as far as I know) no way around this. if you use Photoshop, it's easy to avoid: just change the blend mode from "normal" to "luminosity". If you do that, you are only acting on luminosity and not on color.
I just repeated what I did with your photo, adding a bit of local contrast (essentially, clarity) as well. Then I switched all of the adjustments to the luminosity blend mode. The colors end up much more like the original, but the edit has more pop than the original:
Re doing candids of dogs: I don't do many of dogs, but I do LOTS of candids of little kids. This creates the same problem: it's hard to keep track of things like framing when a 3-year-old is bouncing around a room. In that situation, I take advantage of the fact that digital images are free and take lots, assuming that I will have to throw most out.
