I want to take video of one part of the of production process of glass pressing: gob delivery. I want to assess the shape of the gob, dimensions, and position in the mold.
I do not know much about video techniques, so I tried to use my cellphone camera with very bad results. The main problem seems to be the brightness of the glass.
So I was wondering, what are the most important factors to take into consideration when taking this kind of footage? Should I use special camera? Maybe I should use filters, or maybe I need to know a particular postprocessing technique.
Can anybody shed some light on this issue?
