When i think of food texture i think about how smooth, soft, rough, liquid gritty ,crunchy , lumpy ect.. the food is.I think to be able to capture the texture of food one needs to put much focus on the food by taking the best angle of the food.Most people just pick up their camera and just take a picture but if you want to capture the color or texture of food i think you need a close up focus to be able to do that.
Looking at the cherry pie that i have here on can tell the texture of the pie the cherry look very soft and smooth and the pie crust looks hard and very crunchy.
