Hi
I have a (now unavailable) Actualite, fabulous at the time with a special enhancing plastic light filter underneath within it. 11W LED in it. Just lasted around 10 years. It doesn’t glare back, and shows up all detail.
I’ve enhanced this with other types of LED, so overall the light is ‘rounded’, not too shadowy.
But the best is, as said before always to work in natural light (1pm is great light) from a window, apparently best if over one’s right shoulder. I managed to design it so, nothing like the sun to show up all your glitches!
However, an overhead large flat horizontal LED ‘plate’ would also be good.
Cheers
