Black & White Treatment and Masks

  • April 15, 2023

I have an image I have processed in Color that has a mask that was created by inverting an object selection. The mask has a blue color applied (Color in the Color tab). I then converted it to black & white by applying the Black & White Treatment (the Adobe Monochrome was applied but all black & white profiles have the same effect), but the blue color still shows through as blue. Why is this?

I am including the color image, the converted image, and then a screen capture while I am clicking on the visibility eyeball on the Color tab to show what I expected the black & white treatment to do to the entire image.

If you can explain this, I'd appreciate it!

I don't think you were talking about the mask overlay, like @Rob_Cullen assumes. If I understand you correctly then what you did was add some color by using a color overlay as an adjustment in the masked area. This is exactly why you still see this color when you change the image to B&W. It is a color overlay, so you have 'layed color over the image' in the masked area. That works no matter what the underlying image is; a color image or a B&W image.

    Thanks. I did not realize that is the way it works. Seems kind of strange, but good to know. Very helpful.

    A Mask Overlay will show on any image (color or B&W) when the mask is active.

    A mask does not change an image in any way- it is the Adjustments you make in the Masking panel that change the image.

    Your Blue overlay will show in both Color & B&W modes.
