View Full Version : Photoshop: Partially remove glow

09-10-2009, 05:41 PM

Assume I have a canvas in photoshop. On the canvas I have a picture(object) to which I applied glow to. But, assume I only want the glow on 3 of the sides, how do I remove the fourth?

Lay another object with the same color as the background over the side of the object with the glow where you want it removed?

Oh ..so there is no way to 'erase' it other than covering it?

Well, I’m not too familiar with Photoshop but if the glow is a filter applied to an object you can’t just erase one side. Either you flatten all layers and effects into a bitmap and erase the glow on the side you prefer or you create two objects, one is the main shape and one shape behind that that has a feather edge and is short enough to not come out on the side behind the main object in front of it – oe you overlay another object as I said.

These are my ideas but maybe someone with more in depth Photoshop knowledge has better ones.

Oh, hang on: a mask might be a solution, too (i. e. lay a mask over the object which cuts it off on one side). I don’t know how these work in PS, though.

VIP; Thank you for your answears. Unfortunately a layer-mask can't be applied to the glow-effect itself but only to the object - which means that the new edges comming from the erasing adapts the glow.

Seco: This is an example. You can see that the glow is applied via blending options. Say I want to erase the glow on the right hand side - erase, not cover it.

Finally I accidentially (too late, but whatever) found a solution!
It is possible to make the layer effects new layers. Simply rightclick on the effects and press 'Create layers'. Now the glow is passed to a seperate layer and you can freely erase whatever you want.

or, create a new layer underneath the layer with effects,
merge above layer down to it then erase lol
