I've been having fun taking food pictures with the camera on my iPhone 3GS. The quality is obviously not like my fancy schmancy Nikon D50, but for point and shoot on a mobile phone, it's pretty good. Check out these shots I took recently at Mayfield Bakery & Cafe in Palo Alto. I did some slight photoshop work on the pics but all I did was boost the exposure and contrast a bit to brighten things up.
I loved how the bakery put the bread in baskets because it reminded me of fresh baked bread from a farmer's market. I also liked how Mayfield baked mini loaves because as a single person, I like to get fresh baked bread but I don't want to buy your typical huge loaf because one I'll eat it all or I won't eat more than half and the rest gets tossed.
Just start shooting that yummy food
I know lots of people who think they can't start posting food pics until they can get a nice digital SLR. I say just start shooting with whatever you have even if it is just the camera on your phone. The point is that you get into the action of taking pictures and learning how to "see" a great shot.
A pro photographer taught me that the key to taking great photos is not the camera, it's the photographer's eye. He noted that you could give a throw away camera to someone like an Annie Leibovitz and she'll still take great pictures because of the way she "sees" a shot. And likewise, just because someone's uses a high end camera, that doesn't guarantee beautiful pictures.
That piece of "seeing" advice really helped make my pictures better.
