I like to photograph my lunch when I eat out and post it on my Facebook page (if the food is worth mentioning).
I had a corned beef Reuben sandwich in Santa Fe that was pretty OK. But by the time the sandwich arrived, my beer was half gone. Fortunately, I photographed the beer first (well after a few sips). I created a mask of the first beer photo to drop out all but the glass and the beer. Then I skewed and resized the beer photo until it was more or less the size of the food photo. I subtracted the parts of the beer (using transparency with the beer photo to see through) that overlapped the glass.
I did this using Designer Pro X10.
