A guy stopped in to do a Lith neg Red LED test and I haven't talked to him about results yet. I am curious. I'll report his results.
No matter what the safelight, I move paper and X-Ray quickly in and out of 'safelight' exposure.
Nothing is sitting in safelight long at all.
Enlarging I use scrap for focus.
I'm using these now, and keeping them at 4 feet or more.
