Had no ideal the exposure calculator was going to help as much as it did and easy to use. Really help me get the right exposure time for the emulsion I was using. Worked out perfect
Was inaccurate for me, 20$ for a little piece of paper. nice
Works great. It's helped get us where we need to be.
I couldn’t understand my burning time, if I needed more or less! I bought this and let me tell you, it absolutely works if you’re like me and couldn’t figure out your burn time, you need this!
This calculator is a game changer!! Totally takes all the guess work out of screen burning!! So glad I bought it and will always have one. I actually bought two for my larger screens.
