In an ideal world, I would be learning one new thing about my digital SLR each week. It will take me a lifetime or more to learn all there is to learn about that Nikon D-200 of mine! However, I did learn about the multiple exposure feature that it has and I really like it! You can do many exsposures recorded in the same file and it will adjust the lighting with each shot (unlike film where you have to calculate each shot for the lighting exposure which in turn limits how many exposures you can do in one shot). Wow, this is better than sliced bread!
