For those of us who are keen on food photography, work of Lou Manna, famous NY photographer, is the great source of inspiration without doubt.
On his website you'll find two galleries with fantastic colorful food images (great lighting and closeup!), as well as a blog where he gives some useful advices with illustrations.
And although in my work I prefer not to use glycerin and Elmer's glue (but you know unfortunately I'm not Lou Manna yet :-( ), the idea to use a metal skewers heated over an open flame or just an electric charcoal starter to create the effect of grill marks on meat not going out a studio seems to me interesting. :-)
Not being able to illustrate the post with Lou Manna's photos, I've done it with mine ones. Hope, you wouldn't mind...
