Discoloration

[fullmetalchrono]

Hi,

 

i'm trying to fix discoloration on an old photo. I realized most of the discoloration goes when I view only the blue composite layer. How can I export only this layer. Currently when I export all layers the discoloration remains.

Assuming you are using Affinity Photo:

1. Select the image in the Layers panel.

2. In the Channels panel, right-click on the layer's Red channel (not the Composite Red one) & choose "Clear" from the popup menu.

3. Repeat step 2 for the Green channel.

4. Optionally, right-click on the Blue channel & select "Create Greyscale Layer," then delete the original layer.

5. Export to the desired format.

Hi. Thanks. When I have both the blue layer selected it appears fine. But when i delete the red, green and alpha layers the photo changes to completely blue.

Don't delete the alpha channel, just the red & green ones.
