Re: Separating Colour Tones Before The Black and White Conversion
quote: Soooo.why can't you just do the same with the sliders in normal blend mode and mask the same way - and add a B+W again on top?
You can do that but you run the risk of changing the hue values of the pixels which maybe not something we want to do.
We may only want to change brightess

Re: Separating Colour Tones Before The Black and White Conversion
thanks for the reply- when I adjust the sliders though I can't see with my EYE that theres any difference , but you're saying at pixel level(i.e.techinically) there IS a difference?
I.e. is the sliders adjustment in the B+W adjustment layer in normal blending mode IS affecting the hue even though what you see is just a change in luminosity or perhaps more accurately (brightness of specific tones)

Re: Separating Colour Tones Before The Black and White Conversion
so another way you could do this is to have the B+W adjustment layer set to luminosity and have another B+W ad layer above it set to normal, but click on the luminosity layer and make adjustments with the sliders there to see what the separations look like in mono, rather than doing it first before adding the second B+W adjustment layer
Does the ams thing -right? i.e. changes the luminosity not the hues?

Re: Separating Colour Tones Before The Black and White Conversion
This all seems to be complicated and convoluted. Having spent some time playing around with the Quick Edit panel I found a way there which seems to do the job. There is a button labelled 'Luminous Layer' and when this is selected with a colour image one can see the tonal separations. OK, it is not selective but its no great problem to mask out what is not wanted.

You are correct Norman, the Luminance button is an easy way. The hardest bit is trying to get people to nuy the panel

Re: Separating Colour Tones Before The Black and White Conversion
Some people can't see a good thing when it's right under their nose. I am not saying that the results achievable by using the panel cannot be made by other methods but, for a person like me where time presses, (the old fellow with the scythe isn't far away) it is relatively fast and easy.
