I'll leave the tips to the people who know! Nice, subtle changes. (I tried masking tape suck over the flash - took a pic, then another layer ditto etc, until I realised my damn camera must have been compensating exposure on the light available. Clever, if it does, but it's something I'm gonna have to learn. Out taking some pics today in the woods, and the exposure crept up long enough to allow shake/blur to occur. Gonna have to start using the tripod more!)
