Cool pics Lottie, thanks for sharing them. There does appear to be a lot of vibrant colors in the waters off of St. Lucia. For a relatively new diver taking a camera underwater for the first time, I would say you did an excellent job. Nothing beats practice for getting better, and as iDiveChick alluded to, Photoshop can be your friend for bringing out the real magic after the dive. Hope to see more photos as you progress.
