I am new too, and I need clarification on how to get that channel to the layers to work on. I read somewhere you could control click on the channel but nothing happened? As far as the rest it is over my head but if I just got the first part for now I'd be happy. baby steps

Hi Sheri.

I read somewhere you could control click on the channel but nothing happened
This should give you a selection based on the highlights of the channel. But this is not really what you want.

Luminosity is just the Lightness information of the picture.(no colour)
There are several ways to get this.

A) Image > Mode > Lab and a cut-n-paste back.

B) 1 New layer
2 Fill with 50% grey
3 Set blending mode to Saturation

C) Apply Image
D) Copy Paste
E) Channel Mixer.

Channel Mixer is probably the easiest and most versatile. Especially with a damaged picture because it is very controllable.

For Example setting
Red =33
Monochrome checked.

This gives the same as Desaturate.

Red =30
Monochrome checked.

This gives the Human Perception flavour of Luminosity

With a damaged picture it is often possible to extract a ‘better’ Luminosity by playing with the sliders.
In this case if you look at the Channels and click on them you will see that the Green channel contains the most detail.
So back in the layers Palette click on Channel Mixer and use
Red =0
Monochrome checked.

This is how I started my restoration. I used levels etc to repair this and then added the colour info back later.

Hope this helps
