removing duotone settings

[pixelzombie]

i can't seem to get an image back to grayscale mode when i remove the duotone settings, the image will take on the luminosity of whatever spot color was being used and i want to avoid that...

I see what you mean. Is it better to convert to RGB, then choose the best channel?

[pixelzombie]

i think it may just be to make sure the curve isn't alerted and then choosing a black for the spot color and then removing the duotone setting, i'll have to post the same message on the adobe board...

You can't just switch it to monotone first? I did some quick tests and that worked for me. Otherwise it's doing exactly what you ask of it, just as if you'd moved from RGB to CMYK.

[pixelzombie]

even in monotone it keeps the luminosity of whatever color you are using, even when i use solid black with the color picker...

How strange. I deliberately tried to muck it up, but it simply deleted the 2nd duotone channel when I converted to monotone. Perhaps your first channel was not black?

[pixelzombie]

it wasn't black, it was 2 different shades of brown and i wanted to see the range of the graycale image the client had supplied..

[Damo77]

I didn't think anybody used duotone mode any more ...

[pixelzombie]

neither did i, but we got some files from a client in that mode and we have to match other files to that look...
