Yes, I admit it. I am that Asian guy that takes photos of food as it is served at restaurants. Why do I do it? I do it because I think food is beautiful. I also do it because my long-term memory needs crutches. Photography helps me remember what I ordered the last time.
In general, I tend to prefer being seated inside the restaurant near a window, but the restaurant was pretty full and they had covered outdoor seating. With the overcast weather, the lighting this day was wonderful for food shots. I find light coming from behind the food to the right or left is what I like as it creates dimension and texture. The sauce pattern on the plate, and its rectangular shape made me think a top-down camera angle would best capture the artful plating.
I like the 35mm field of view for a lot of my food shots. For one, I don't have to stand or leave my seat to fit the plate in the frame, I can get relatively close to the subject which makes the subject more appealing to me, and the wider lens keeps more of the subject in focus so I don't have to close the aperture too much.
