I only just discovered this website and it’s already got my heart on rapid-fire. Photojojo sells all kinds of wonderful camera-related things (except for the actual camera, lenses or studio equipment). It’s not cheap, a few items are currently sold out and they seem to stock a lot of gadgets for phone photography (which I grumpily don’t 100% approve of) but look at these lovely things:
Creative Bokeh-kit (I tried and failed to make one of these once)
Lomokino 35mm Movie Camera
I have recently acquired a ring-flash adaptor, which is like a round periscope which attached to a normal flash gun, for more even portrait lighting. Will post some results when I’ve tried it out properly. Also, they send out a little toy dinosaur with all orders. What’s not to like?
