[Applying live filter layers to specific channel, possible?]

Thanks a lot!!! I will try this over the weekend.

[Applying live filter layers to specific channel, possible?]

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
