Still a novice despite years of using Affinity photo.  I am trying to adjust brightness of one area of image.  I set the appropriate brightness. I press command-I to invert.  I select paint brush, opacity 100%, flow 100%, hardness 0%.  I select white to paint over adjustment layer hoping to reveal brightness desired, which has previously worked fine for me.  Now, nothing happens.  It has always worked fine before.  Not this week.  Tried a factory reset in case I had accidentally hit something.  What I would say, comparing previously successful photo edits is that when I hit command-I the adjustment layer icon now goes completely black, whereas on previous photos it seems to have some white.  I imagine I have just made a schoolboy error but... help!

I’ve attached a short video showing one quick way you can apply the Brightness Adjustment to part of an image.

  • Apply the Adjustment and set the settings for it.
  • Use the Flood Fill Tool and fill in Black on the Adjustment layer.
  • Select the Paint Brush Tool and select White to paint with.
  • Paint the area you want to be brighter.

You can use the same technique on any Adjustment layer, not just Brightness.
I painted very crudely just to show what happens, but you will get a better effect if you paint with more care and choose your brush settings – flow, hardness, etc. – more wisely than I did.
There will be other methods but the best will depend on the image you want to apply the effect to.

Doh! Thanks very much, Ray.  I don't know why I didn't see that.  Not so much schoolboy error as old age, I guess.

 

And thanks, Garry.  Interesting technique - and one to remember not just for brightness, as you say.

Have you accidently switched on "Protect Alpha" in the tool-context-bar?

I'm a bit surprised that a Factory Reset does not switch that to the default off setting

To save time I am currently using an automated AI to reply to some posts on this forum. If any of "my" posts are wrong or appear to be total b*ll*cks they are the ones generated by the AI. If correct they were probably mine. I apologise for any mistakes made by my AI - I'm sure it will improve with time.

Yes, me too.  But the same issue occurred before and after factory reset.  I suppose it's possible I involuntarily twitched while mouse was in vicinity of protect alpha both before and after reset.  I'm going to have to watch myself, just in case!
