BTN = By the Numbers....
RGB numbers being equal will produce Gray.
100,100,100 = Gray.
S,H,N = Shadow , Highlight, Neutral.
No problems..

Thanks for the answer and good to see people are still checking the board. Hello everyone. I have been to Turkey and Fiji and have come back with lots of photos needing lots of work.
I see so many colour problems now but often don't have the skills to work on them.
I am using BTN quite reguarly now but still tend to go back into lab for a colour boost and to add contrast if needed. Is this a good workflow or would it be better to stay in rgb and adjust from there.
thanks Julie

Hi Julie,Lab would seem to be the ideal space to add contrast and saturation.GregM

Julie,
Lab is great for color boost and color contrast...
I'd make my contrast adjustments on a separate layer using RGB and separate channels.
If you use Photoshop...
I would create a layer copy of the image, Select the copy and Select the channels tab. Open each channel in CM as a black and white version and adjust each channel for the best contrast. I would consider replacing a weak channel with a stronger one...and then apply the layer using the Luminosity Mode.
If you use Elements you can do almost the same thing by creating a layer copy and using CM to adjust each channel separately by clicking on the channels view in CM...See Screen shot...Ignore the colors as you will be applying the layer in Luminosity mode again...
