Thanks for your suggestion, Mike. I like the crop better, too. But this is a crop of a crop, so this is probably about 8 MP.I prefer the crop in the revised version but I prefer the monochrome treatment. That's because the color distracts my eye from the goings on of the three experts.
It's not problematic for me. If you want to use a more traditional aspect ratio, try cropping at the bottom immediately above "The clear way to straighten teeth." Though I appreciate the humor in that tag line, including it in the photo wouldn't be important to me.Though the aspect ratio is perhaps less pleasing.
