The first image is the image I shot 'on meter', meaning at the settings I chose.
The second image is an HDR (high dynamic range) image which combined the image above with two more which were one stop of light more (lighter) and one stop of light less (darker) than the image above.
Now, this was a remedial trial of HDR using Photoshop, but I can see how there are more details in the shadowed areas and the highlight areas compared to the first image. I kind of like it, but I don't think I'll be creating HDR from everything I shoot. But sometimes it might be fun.
