Since I've never used Auto or Program modes, I don't know what criteria each one uses to determine exposure (1/25" shutter speed for a 48mm focal length). It's possible the mode for the first image doesn't factor in the relationship between the focal length used and the shutter speed. Many people wouldn't have tried to use such a slow shutter speed of 1/25" like the first images uses. In the second image, the dark bumps are noise due to the ISO being 11400. But if I were to use one, I've heard Program mode tends to be a little better. This is where understanding the Exposure Triangle and how the aperture, shutter speed, and ISO all interact to deliver the final image.</blockquote>
