I have a Fluro Ektar and learned that it used as car parts roentgen machines phosphor glowing plate taking lens.
It is only corrected to green.
What kind of a photograph does it take , what about the colors , sharpness ?
Does it take like Aero Ektar or faraway different strange colors and non sharp pictures ?
No , nothing , it comes and goes , but your answer was inspired me to do something now .
But I will wait more detailed answer , insight also. I last built a box from paper and put a thin paper back and tried the lens , it was sharp and good. But I got green corrected information and I stopped.
