How to remove gradients in astrophotography using photoshop

[@nguyenhoailinh7516]

At 2:20, what key combination do you press to get a picture with only one color like that?

[@RaysAstrophotography]

Pretty cool! I had it but I didn't know how to use it earlier!

Are you selecting the background layer in the panel?

[@clungebucket23]

aren't you supposed to connect your layer mask to the layer underneath to apply any adjustments?

[@AVAstronomy]

clungebucket23 either way the mask is applied to the editing action.

I couldnt work out how you got rid of the light pollution

[@AVAstronomy]

Duplicate your background layer. Do a color sample using the dropper of your stretched image, Usually has a brownish/yellowish cast to it. Then press Alt and backspace. This will turn the top layer the color you sampled. Then go to apply image and subtract that top layer image using an offset of 30. Hope that helps. Thanks for watching! God bless and clear skies!

Good video, one of these days I'll make the jump to PhotoShop and I'll comeback and watch this.

Chuck's Astrophotography thanks chuck! What do you use to process your images? Pixinsight?

[@ChucksAstrophotography]

@@AVAstronomy RIght, Pixinsight, but with what little I do know of PhiotoShop, I use it to tweak the colors.
