Quote:No white background as in your example.

I see. If you haven,t this layer, create it and name it is General Background

Quote:After that you say:
1. Select Layer 1
2. Removing blue background from the Layer 1

As you see my layer 1 is not blue but brown!
Layer 2 is blue with artefact.

Here my error in the description

Quote:After all the job done the artefact is awful if I remove background. Cyan everywhere, if I remove it in palette it removes all the glow too.

Oh ... initially you should be three layers


The background color in the layer with the image of the artifact - Transparent


I can not understand how you removed the blue background, so spoiling the picture? Background eraser tool with a tolerance of 1% to remove only one color, in this case the color 0 255 255

The glow you have to do, only after the background image of the artifact will be transparent!

This damn language barrier! If I knew the English language, it would long ago have you all well explained
