I didn't start getting the hang of armchair photography until I took a photography course at college. During the course I learned a lot of useful information and discovered that yes, like everything, the more I did it the better I got (within reason...I still wouldn't attempt to sell any of my prints ha ha!) One thing I've taken issue with however is the "metering off the palm of your hand" when you do not have a grey card. The instructor told us it is the next best thing. However, when I do meter off my hand, the image is almost over exposed. I'm holding my hand up, focusing and adjusting until the exposure value is 0. Am I doing it wrong?
