This calculator is an easy way to ensure proper exposure time. This size is 1/2" x 3 3/4" so you can place the image on your screen without exposing. How to use: We put the calculator on the screen as the normal picture. Then perform the exposure time you think is correct. When you wash the image, we want to leave 7 solid steps on your step. Unsure where to start? Please insert the following numbers: Pre-emulsion with 500 watt halogen light Start in 10 minutes. 2 part diazo emulsion with 500 watt halogen light Start in 15 minutes. Photosensitive emulsion using multiple UV fluorescent lights Start in 3 minutes. Two part diazo emulsion using multiple UV fluorescent bulbs Start in 6 minutes. Review: Easy to use. Quickly get the correct exposure timing. I think it's over priced for what it is however there's no one else selling this item. This only comes out when you need to try something new so it should last awhile.
