This second image is the same one processed on my computer to make it more to my liking. I brightened the image, increased the color saturation a bit, decreased the contrast and sharpened it a little.
Just for fun, I took the image with basic side-lighting (no reflector) and processed it to my liking. this is what I ended up with:
I had to use add more brightness and decrease the contrast even more to get this result. And I don't like it as much as the one taken with the reflector. What that tells me is that, even though post-processing can help, it is still better to get the lighting right during the shoot.
Again, the differences become a little clearer if you click on the photographs to enlarge them.
