I hadn't actually heard of a diffuser until I bought my first DSLR camera (Nikon D40) recently. When I found out what it was it sounded like a great idea to stop the white, unnatural colours you get when shooting pictures with the flash on. I ordered this item and it arrived very quickly. It fitted onto the hotshoe mount easily and after trying it out with various different subjects I can definitely recommend it as an essential piece of equipment for taking flash photos. The colours are so much better, more natural - I couldn't believe the difference a cheap bit of plastic made to the pictures. Highly recommended!
