You will hear me hounding you about having the flash on....in this case with the saturation pushed over the top, the brutal flash takes the image to another realm.
I tried the macro shots with the flash on and the flash off to get a feel for both results...of course my camera won't just take a shot without the flash and be done with it, it holds the aperture open for several seconds so unless i have the camera on a tripod it's a small nightmare!
