I love this series "The Breakdown" with Miguel Quiles. I grabbed the video above, because it's the perfect way for you to get started and raise the bar on a few of your food shots. And, while we all recognize a Big Mac, pay attention to the way Miguel has accomplished the lighting and chosen depth of field.
On a totally unrelated side note - I can't help but wonder how many of those I ate as a kid, usually two at a time with a shake and fries - 2000+ calories - Ouch! LOL
There are fifteen videos in Miguel's series - each one a short introduction to another technique and skill set!
As always, Adorama lives true to their tagline - "more than a camera store!"
