just got the canon twin flash for the macro lens and i am loving it. this is the first time since owning the camera that i felt i was able to take a pic that looked good without doing a lot of post. still have a good amount of work to do though. still looks over exposed on the tops of the corals when shooting under the 400 halides and the saturation is a bit high i think. i need to work with bouncing the flash a bit to try and help round things out. not perfect but ALOT better then ever before
