WELL, worth the printing time and filament! Overall, I think it’s a very good diffuser, but the front solid wall is rather thick, which means it takes a very strong flash (1/16) to get through it and give adequate light and even then the camera is using a fairly high ISO. HOWEVER, I don’t know if this is even something that the Print author could influence, as I could not seem to really affect it by changing wall, loops, etc. and using this ePrint, has allowed me to take much better pictures than I have ever taken before of insects and flowers.
