I am a plastic surgeon who is searching for a good way to morph patient photos. In our field, patients often want a simulated image of their nose after a rhinoplasty for example. I know people usually use Photoshop for this but I have Affinity from design work in the past. I would like to use it if possible. Is anyone aware of how to essentially edit features on people to simulate surgical results?

Affinity Photo has a Liquify persona that could be useful for that.

Good morning, @Rachelle E. I found your post a few days ago and thought about it quite a bit. (In a "prior lifetime" I had an Occupational Medicine practice and, while it didn't require much in the way of aesthetics, I was drawn to your question.) Also, I've always found the Liquify Persona to be difficult to manage, and only helpful (to me, at least) for very subtle changes.

I stumbled across what I think is a better (and easier) answer. That is the "Deform Tool." This is a destructive filter that can move points in a photo around, relative to an anchor point. I have attached a side view of a pre-rhinoplasty patient (from the web) as an example.

To use the tool, I duplicated the background layer. This gives me a "Before" and "After" layer, and I will only be using the Deform tool on the "After" layer. First, place an Anchor point by clicking on the photo (with the layer selected). In my example, I have colored this point red. Now, place multiple other points in various positions on the layer. I've indicated these additional points by accentuating them with a white outline. You can use the Move tool to move them around, and they will transform the image by moving image pixels relative to the anchor point.

In my example, I've moved most of the points along the periphery of the nose to new positions, and have indicated those moved points in green. I've left two points on the top (along the forehead) and the bottom (below the nose) so as to limit the deformation of those areas.

This might be a reasonable way to simulate the anticipated changes in a patient's post-op results.
