Thank you for responding but all those videos are about lighting and developing RAW photos and such. It seems to me that affinity is more like Lightroom then Photoshop. I love the apps but they are lacking some key features and seems to me that more of their lessons are centered around developing images and not image manipulation. IT WOULD BE NICE TO HAVE A LITTLE MORE LESSONS IN IMAGE MANIPULATION AND COMPOSITING. In any care I believe they are doing a good job despite the need for improvements. they have my thanks and support still.

You might try a Google search for “affinity photo hair”.

In former lives, I struggled with isolating hair from a background using PS. Never found a great way of doing it. I basically isolated what I could and erased what I couldn’t. But, I was not working on high fashion stuff so it did not matter that much. For me, the best solution, if it is important to show every hair, is to shoot the photo so that the background does not need to be removed. Not everything can be accomplished in a photo editor. Just my opinion.

The best method depends on the actual image and what you want to achieve.

The basic method is

1. have your image opened in photo
2. rasterize
3. use selection brush to either select subject or background
4. use refine
5. set output method to „new layer with mask“. This will automatically do color decontamination
6. if the results are not satisfying, upload the image here and ask for advise for the specific image.

To select based on channels: use channels panel to activate individual channels. Before starting selection, activate the channels which provides the strongest contrast between background and foreground. This method is a bit overrated as Affinity automatically considers the channels with strongest contrast.

To improve selection in images with very low contrast, use a copy of the image in Tone Map Persona and maximize local contrast. Use this layer for selection creation purpose only. Hide it and choose the original layer for further edits, e.g. creating masks.

I remember watching such tutorials years ago. The basic technique and tools are still the same for v2, so you simply have to search the old tutorials for yourself.
For example this one:
