I wanted to share with you a new (to me) website dedicated to teaching folks how to shoot food called, "Learn Food Photography".
You will find some great resources including a collection of 45 amazing free tips and tutorials to learn (or improve your) food photography.
They are also currently having a contest that includes prizes like a seat in a class taught by food photographer and instructor Ron Goldman and a Think Tank camera bag, so go check it out.
Here are a few more very good, very useful online (and free) food photography resources:
Big and Tasty
Digital Photography School
Food Photography for Bloggers
Learn Food Photography
PixSylAted
Wright Food
And for those photographers who take themselves just a bit too seriously we'll wrap up this post with a (funny) food photography video. Enjoy
