I understand that good food photos are ones with highlights, like backlighting? For example, they have a window on the other side of the food and you shoot into the light. Yours seems to be like that, and very bright. Love it.
Ya, Chris, Soft indirect natural lighting helps alot. But if you don't have that, a little fiddling with the white balance, and exposure compensation goes a long way.
The exposure typically need to be pushed brighter when shooting at anything with a bright white background...like dishes. Camera exposure logic will normally attempt to render the whites into greys, which will under expose the actual interesting parts of the pic.
And you always have the option of pushing the image exposure in post to compensate for mistakes. I always under-expose my shots, and push my raw file in post production, because you can almost always pull up details from the shadows, whereas it is impossible to pull back details from over-exposure.
Today it's our first attempt at cherry vanilla ice cream....This was shot with center-weight exposure, -1/3 stop, but then pushed nearly 2 stops in post.
