Just as an exercise, I decided to explore ways to create vignettes with Affinity Photo. I stopped after identifying 20 methods. Attached are my notes for your pleasure.

Using the Dodge and burn on a mask layer is handy when using to affect only shadows, midtones or highlights. Eg. Dodging a lighter sky through a dark tree.

Here's a way to quickly perk up a sunset, using just blend modes.
Let's start with a basic sunset picture. This is a view over Madrid a couple of weeks ago.

Now duplicate this layer twice (Ctrl-J, Ctrl-J), then turn off the top layer (check mark on right in layers panel).
Select the middle layer. Invert it (Ctrl-I). Change Blend mode to Luminosity (drop-down box at top of layers panel that says 'Normal').

Hmm. A bit strong. Turn Opacity (top of layers panel) down to 50%.

Now we have (a) interesting colours in sky and, notably, (b) grey elsewhere (the invert turns darks into lights which turned down are grey). So we can use a contrast mode blend which ignores greys. So turn on the top layer (box at right of layer) and set blend mode to Hard Light.

Ole. A perkier sunset. You can play with the blend modes of layers. The middle layer, for example, is also good with Colour Dodge.
If the result is a bit too colourful for you, you can always add a HSL layer above and turn down the saturation. So it looks something like this.

This shows something of the joys of using blend modes. To get something similar could take a lot of twiddling, while this was a few seconds (well, actually a bit longer first time as I was just playing around to see what happens).

Herewith a little document containing mono and colour examples of blend modes in action. I find it useful to see relationships between different/similar blend modes. Also how weird transitions can happen!
Monochrome blend is gradient black to white, from top to bottom above left to right. Colour blend is trickier, with green over red, with both fading differently to each edge (to black, white, grey and transparent). Top (blend) and bottom (base) layers are shown on the first page.
Enjoy!

I did some macros for a 5-level luminosity mask set here:
 

Here's a quick and simple way I used to create a cartoon efffect.
Duplicate background layer. High-pass adjustment layer (as child of duplicate), radius about 10 (don't use any blend mode). Threshold layer (as child of duplicate), adjust to see outlines (up to 49%). Blend mode of duplicate: Overlay. Fiddle with adjustments to your heart's content. Ole.

I might have found an approach for this. See here:

For the photoshop ones yes. For example this is quite good http://photoblogstop.com/photoshop/photoshop-blend-modes-explained (but still not explain how Fill Opacity is used in the blending formula)
However for the Serif - introduced blend modes, they won't be found in these sites.
 
Edit: Your links lead me to this site which document the blend mode formulas of Pegtop, among them Reflect and Glow.

I have tested that they match the behavior of Affinity.

Thanks for the file. Great reference.

Good work. What happens w. different color gradients, considering different color have different luminosity values?

Great visual for blend modes, Dave.

Phew. I've just ploughed through the full set of in-house AP video tutorials, done by the most excellent James Ritson. To help me learn and provide a reference, I made personal notes along the way. Here they are, complete with links to each video, in case they may be of help for you. No guarantees and all that.

very creative and thank you for sharing!
 

APu also could sound noxious ('ay-poo').
Maybe to allow more flexibility for future products, use four letters: APho ('ay-foh'), ADes ('ay-des'), APub ('ay-pub').
This could sound trivial, but it's a branding decision!
