Recently I picked up a super cheap set of extension tubes for my camera and I've been getting into macro photography, especially that of my fine arachnid friends.
However, unless I'm just taking shots of them in their natural habitat, it's rather difficult for me to get them to sit still. I don't want to kill them, but it would be nice to have some kind of container that I can put them in to take photographs.
Unfortunately, glass jars while being readily available have pretty horrible optical quality. So do plastic bags, like this one:
Is there any kind of equipment that I could use to contain an arthropod temporarily while I snap some shots of it? Preferably something that would let me take photos from top, bottom, and sides.
