Review on Optical Crystal Photography Prisms Science by James Crofton

What I like about this product is that it comes with a variety of crystals, which makes photography more fun and creative for a beginner photographer . It is easy to use and creates a cool light effect through these crystals. Each crystal gives a different light feedback, so the light effect can be very creative. As I have already mentioned that I am an aspiring (amateur) photographer, what do I use this product for? I use them for portraits so I can get the effect that the crystal makes the picture more interesting.
