Applying live filter layers to specific channel, possible?

[sisamon]

I have just downloaded Affinity and I am quite impressed with the tool.There is only one thing I have not been able to replicate from my workflow, I would like to apply unsharpening to the lab channel, so far I have not been able to do that.

 

I can toggle the A and B channels off and see display only the LAB channel, but it seems that any actions are applied to all the channels, not just the one(s) that is displayed.

 

Is this possible, am I missing something quite obvious?

 

Thanks

Go to the channels panel (by default in the bottom right) (or View > Studio > Channels)

 

Right klick of one of the channels, right klick on one > load to pixel selection

- then you can either click on an adjustment layer which will use the selection as a mask (which can be edited using brushes for example)

- or you can klick on the mask icon which gives you a mask based on the selection which can then be applied to anything (IMO more flexible)

 

EDIT:

works also with live filter layers

 

Sidenote 1:

I guess to to this in the LAB space you´d have to set your document color format to Lab and then you also have LAB channels.

In the next update (or the current beta) you can also use a Levels adjustment for example in a LAB mode and target one of these parts although the document is set to RGB. So the adjustment layers can be applied in a different color space then the document.

 

 

sidenote 2:

With the upper channel a right klick allows to load to pixel selection

The lower channels right klick allows to create a greyscale layer from them which can be useful for further editing, you can then go to layer > rasterize to mask to use it as a mask.
