Interesting effect I've noticed when shooting portrait shots with my Canon 430EX II Speedlite - when I zoom out completely, (at widest angle on my 17-85mm lens) white (or very light) clothes get blown out, but when I zoom in a bit, say at 35mm focal length, I get much better results. Why the difference in results? This happens in Program mode at ISO 100. The purpose of this topic is not to get advice on how to get better shots, I use Manual mode and EV compensation of the flash to get great results, and the Recovery function of my Photoshop RAW plugin has also saved my butt a couple of times. So all I want to know, why does the above (as explained) happen?
