Spot Exposure Adjustment using Pen Path

Recommended Posts

I want to apply an exposure adjustment to a portion of my photo (Affinity Photo on a PC).  I'm able to do this using a paint brush to define the area for correction as explained here:


However, I'm not able to figure out how to do the same thing using the pen to make a closed path to define the area for correction, rather than use a freehand paintbrush.  Is this possible?  If so, is it possible to edit the path later?

Yes and yes


Draw the path. On the Context toolbar, click Selection.


Any correction will just affect that area. You can add to or delete from the selection with the selection brush.


If you make a Mask, instead, you can edit that separately (resize, edit the path and so forth).

You will need to make a duplicate of the image first if you make a Mask.

Thanks Toltec -

That works.  When I apply a blur to the mask to soften the transition, it changes to a pixel layer.  Do you know of any way to have soft edges, yet be able to go back and modify the pen path?

Hi edferg,

Welcome to Affinity Forums :)

You can apply a Blur Layer Effect (FX) to the Curve that you are using as a mask to soften the edges. Select the curve/mask layer in the Layers panel and click the FX button on the bottom of the same panel then add/tick the Gaussian Blur effects and adjust as desired.
