How do you add gradients together?

Recommended Posts

If I want to blend a few gradients together, I would think of this:





With the masks supposedly cancelling each other it should be a blend of 1 into 2.

But it doesn't seem to do that in real life. You get bands forming in the middle part.

How would I make an uneven gradient?

argh I pasted in and it looked fine but it doesn't save....

I mean I'd make layers like this, with a gradient in the mask going opposite directions, or even circular gradients in the mask.

I' m creating a blank wall which has different lights faling on it. It may have 1 gradient going up and down, but also light falloff going from L-R. And faint hotspots that may be from downlights.

It only needs to be monochrome.

Or sometimes I'm trying to blend a fake wall with a real like your extending bg tutorial.

Definitely DON'T use gradients on the masks.  The masks must remain all white.

Use as many gradient layers as you need.  Maybe you'll wish to put them on a blend mode, such as "Multiply" or "Screen", but in some cases "Normal" mode will be fine.

Make sure you make good use of transparency in the gradients.

I want to help you more, I really do, but I need to see what you have in mind.

DO NOT USE MASKS.  I can't stress this enough.

Yes full wall in this case. I've masked out the subject on another layer. Putting a wall underneath, and a noise layer.

But in some cases I have no transparency in the gradients . If I'm copying colors around the L & R of a subject, which are different because of the light positions, both bgs are a vertical gradient in that case.
