I've started delving into black and white digital photography and I have this issue that seems to be bothering me.
I convert my photos to black and white either using Lightroom or Capture One Pro and I make the RAW adjustments (i.e. use the colour mixers, contrast etc).
I then export the image with the changes to Photoshop to do some final changes. However, whenever I open the image in Photoshop, I notice the black and white image has gained
a very slight green tint to it. As in the whites don't look white, they look greenish white. If I compare the image to the black and white image from Capture One Pro or Lightroom, it looks like a true greyscale image.
So I started messing around in Photoshops colour settings.
If I convert the image to a greyscale (which removes all the colour channels) with a gamma of 2.2, the green tint disappears leaving me with a nice greyscale image.
If I keep it in an RGB colour space (I've tried DCam, Adobe RGB, sRGB, ProPhoto) the green tint comes back.
I've tried changing the intent, different engine, everything that the colour settings allow me to. It's whenever I work in a colour space, the black and white has a green tint to it in Photoshop. Convert it to greyscale and it's gone.
Is this normal for Photoshop? Even Windows Photo Viewer doesn't display the green tint.
I've calibrated my monitor with i1 Display Profiler and use a Wide Gamut monitor.
