saturation brushes

[cadwr]

Photoshop has a saturation / desat brush nested in the dodge & burn brush tools. Can't find tyhis in Affinity Photo.The only way I can see of applying saturation to a specific area is by selecting it first - & this doesn't allow subtle changes. Can anyone help?

Hi cadwr,

Affinity Photo does have a Dodge and Burn tool.  See this video for more information

Good spot. 

We also have the same tool, in the same place  

If it's not showing for you @cadwr Click on View>Customise Tools and you can drag the Sponge tool onto the toolbar

thank you. found it.! Interestingly, it seems to work backwards. Clicking saturate moves the option to desat, & vise versa. Clicking vibrance does nothing at all. Never mind - problem solved Thanks guys

Using HSL Saturation brings the colour back and adds a brightness to existing colours, vibrance is a more subtle effect than HSL when desaturating.

Thanks, Firstdefence. Yes, I know about this, but my concern was to be able to sat/desat selectively. HSL ,of course, acts globally

A non-destructive way to "paint in" saturation changes is:

Add New Layer on top of the base layer you want to modify. This new layer will be transparent. No visible change.
Set Blend Mode of new layer to Saturation. Still no visible change.
On Color Panel, set the 2 colours so that one has 0% Saturation and the other has 100% Saturation.
Select the new layer in the layers panel.
Choose Paint Brush Tool and set Hardness to 100% but Opacity to a very low value, say 5%.
Paint onto the new layer, using the Color Panel swap to alternate between the 2 colours according to whether you want to decrease or increase the saturation. Each stroke should modify the saturation slightly so you can build up to greater changes step by step. And you can use Erase Brush Tool to undo the effect in any area.
