There's been some questions about how I do the snowshots. I've given some verbal information about the technique, but I guess, a photograph about my setup is needed. So, I made the photos above and below (in the gallery) just for the occasion.
The setup is simple really: All I use is an old transparent CD storage box, some water and my trusty old A4 lightbox for lighting. For the bottom of the box I have a piece of gray Lego baseplate cut in form and hotglued on a piece of acrylic sheet to give it some weight. Legos float because of all the air trapped inside individual pieces.
Anything I want to shoot is then easily mounted on the baseplate and inserted inside the CD box.
Photographing "snow" in this scale is difficult, and to amp up the challenge I wanted it to fly around. The answer was not to use faster shutterspeed but to slow the snow down.
I had a wacky idea to submerge everything in water, it slows down everything that moves. The water also causes light to reflect from solid surfaces in a way that sometimes helps hiding the miniature scale. This is an old concept I've been toying with for ages. For the snow I use ground plaster of Paris—reacted, not unused gypsum powder! It is a passive material that doesn't stick to anything.
Lighting is done with the lightbox freehand as you can see from the photo below.
I shoot a lot of frames because the "snow" is impossible to control exactly. And then some Photoshopping is in order, but not always, sometimes none is needed.
