Review on 📸 Sumnacon Crystal Triangular Spectrum Photography by Adam Taylor

It works! Makes a beautiful rainbow with the right angle and light intensity! At first I was frustrated because I could only show white light, but then I tried again in the morning when the light was at its most intense and at the right angle, creating a beautiful rainbow. Try it in direct sunlight where the sun is at an angle of 45 to 90 degrees and place the prism vertically. If you can't see a rainbow but can see a beam of white light emitted by a prism, slowly rotate the prism while standing straight.
