I have been using a Sony Cybershot DSC-P8 3.2mp camera for awhile and have been rather unimpressed with the images especially in direct sunlight. I was looking at Canon SD400 5mp camera to replace it. Is this camera really going to be better and is the image quality going to be better in the sun. I detail alot of cars and take pictures for my clients to show the before, after and process and when in the sun the colors are just faded or not true colors. Im also going to England and Ireland for 10 days over Thanksgiving, I was looking at a 512 memory card possible a 1G, any suggestions to what type?
