How do I create a radial gradient mask to create a glowing ball effect?

Recommended Posts

I want to create an effect of a radial color burst on top of my existing layers. It needs to be normal blending mode.  and I want it to gradate from intense in the middle to transparent on the edges. How do I do that in affinity photo?

Ok. So I tried it. It’s close to what I’m after but unfortunately the filter effects the rest of the image. Changes the ambient light value. 
i need this to simply be a gradient sphere of color where I can control the roll off of the color on the edges to completely transparent.

I'm just guessing to what you want so maybe post the picture where you want it to appear

Not sure if this is what you want but...

Use the rectangle tool to create a rectangle layer above your image layer, extend the shape to a square whose sides are a little bit larger than the diameter you want your gradient. Place the centre of the square where you want the centre of your gradient to be. Set the fill to radial gradient,  choose a strong colour at the left end of the gradient fill pop-up, set the opacity of the right end to 0. Use the Gradient tool and the sliders in the fill panel to adjust according to taste...

Hello All,

Just to follow up, I did resolve the technique.

Two great ways to do it, either with a radial fill within a shape which ends with a transparency value of zero, or the same thing with a mask on a layer with a gradient fill.

See attached screenshots.

Thanks h_d for your suggestion.

Problem solved.
