first video of 2018 and first tutorial experience, i hope that you like it and it can be useful to you.
Tutorial subject: how to make a focus ground glass for your 8×10 camera.
First of all i use a 2 mm thickness extra clear glass, cut to fit the frame of my 8×10 folding camera, with a chamfer of 1.5 cm for each corner.
Before the sanding phase I make sure to eliminate the remaining dangerous edges.
Only at this point i start with sanding phase with carborundum. I put carborundum and water (a little bit) on the ground glass and i use other small glass to proceed with sanding phase. Also with patience I distribute and “scratch” the glass with circular movements until the water is absorbed.
When the he water is absorbed i wash and dry the glass to check the result, if it is not uniform, I repeat the sanding phase.
To obtain the ground glass in the video i need to repeat the sanding phase 3 times.
See you in the next video!
