I really love the mini figures from Lego.
Photographing them is great with a macro Lens and Flash set up.
My interest has been Marvel Comics, Star Wars and Movie Characters.
One of the things I found frustrating was having to purchase the big Lego Sets just to build my Marvel Avengers Set. eBay and Amazon came in handy, however, resentment set in when I noctice the outrageous prices for the mini figures.
I am so glad I found a company that specialises in Lego mini figures of famous characters. They are called Mini Figures - http://minifigures.com. Check them out, they have a great collection. I built my movie characters from their range and they look great.
I have a lot of fun photographing these because of the 1:1 life size representation on my image sensor. The characters come to life.
I am a Lego Photographer along with everything else I enjoy creating images.
