The finer things
If your food has some interesting textures, use a macro lens to get in really close. Don’t be afraid to fill the frame with the detail – sometimes the tastiest food photographs are close-up shots. Capturing the detail of this bread makes your mouth water; you can almost hear the crust cracking. Don’t forget, the closer you get, the shallower your depth of field becomes (shallow depth of field is inherent in all macro photography), so you either have to change composition so that as much as possible is on the plane focus, or narrow your aperture to increase the depth of field.
