How to apply a blur effect to picture under pen shape (poly art)

Recommended Posts

Hi All,

 

I would like to use Affinity Photo to create some nice low ploy art.

In other software packages you draw some triangles and apply an average blur.

 

In attached image I have started to draw some triangles using the pen tool and grouped them above the image.

 

Please can someone help and advice if there is a way to apply a blur effect on the entire group which will affect the image underneath it. (Not the pen border).

 

Any help is much appreciated! Thank you.

I am not sure I understand what you are trying to do but if you want the pen strokes (which I assume is what you mean by border) to remain unaffected I think you will need to create a second group of unfilled triangles with the Pen tool (or with the Triangle shape tool) & place that group above everything you want the blur to affect.

Hi Tarek,

Welcome to Affinity Forums :)

Go to the Layers panel, select the image layer then go to menu Layer ▸ New Live Filter Layer and select the Blur filter you want from the top section. This will apply the filter just to the image leaving the grouped triangles above intact (the filter will be attached to the image layer).

Is there also a way to convert shapes drawn with the pen tool into selections? that would help me as well if possible.
