In general, the best recipe photos are taken fairly close-up,
are sharp and have good color balance.
Often, they have one or more accompanying

Get at an angle, not 90 degrees. Recipe
photos taken at a straight down (i.e., flat) angle are often less
attractive to the eye than those taken at an angle.
