I wonder if batch converting the images to change the white to 50% grey would give me the ability to better tune the exposure time? The idea is that since the Vorex is so reactive to light, I may not be able to tune the exposure time in fine enough increments. If the difference between success and failure is 0.1 seconds - and I cannot step the time in finer resolutions (say 0.001) - then reducing the initial intensity of the light pixels by some factor should achieve the same result. So where it took 0.7 seconds to cure before, now it takes 1.4 seconds - or more depending on the image grayscale conversion amount. Now a 0.1 second change has less light reaction and so the time can be adjusted on a more granular level.
Taking this example to the extreme, if a slice cured in 1.0 seconds @ 100% white, and I changed this to 1% white, I theoretically need to expose the layer for 100.0 seconds to get the same level of curing - right?
Does this actually help or hurt the light bleed? I can see it helping fine tune the exposure time to it's absolute minimum value, but maybe it never actually helps with light bleeding through to unwanted areas.
My logic in this may be flawed, so if anyone has a better explanation I would appreciate it.
