How to flip Brightness and preserve color in Photoshop?
as the title is saying. Using Photoshop, I want to invert the luminosity of my image using adjustment-layers, while the colors stay the same.
So here is my example image:
- Dark Background (it's totally black in this example)
- Light Text (it's totally black in this example)
- two glowing edges
- White Background
- Black Text
- Colors are the same
I don't know how I can prevent the colors from being manipulated as well.
If I try to invert the image with an Invert Adjustment Layer with the blend mode of luminosity (which is the last in the list) it won't give me the desired result.
As you can see here, the Hue of the glow is still the same.
But the brightness has been flipped too.
I also tryed to calculate Channels in LAB-Mode and could not come up with a decent looking result.
I don't want to manually select the text & the shape and fill it with the opposing color. That destroys the edges and looks awful.
Quick thought at the end: I need an selection by saturation if that's possible ... ;-)
Try the following to see why this doesn't work;
- Open your image
- Go to the LAB channel mode
- In your channels look at the lightness channel (L)
- This is your image stripped off all color
- If you invert this you will see you get pretty dark shadows
- no colors have been manipulated here, only the luminosity
- therefore > the problem lies with the luminosity.
You simply get shadows that are too dark.
This layers example should get you close.
