In digital painting and illustrations, Colour Dodge is used for lighting effects, like lens flares and stuff. You can fill a circle with a color to black radial gradient, then resize it into an ellipse with a duplicate on top, rotated by 90° so it forms a cross and looks like a shiny highlight.

nice video as always Dave, I have some suggestions: You mentioned to reduce opacity. I find that just fades the colors. Color dodge and burn when the FILL slider is set to 100% reduces the number of colors to the base 6 or 8 colors only. I never use opacity when using these blend modes but i do use the Fill slider. When you reduce the fill you increase the number of colors the algorithm allows, I know you know this but its worth mentioning. Here is a good video that explains how this works. Its in photoshop but affinity works the same way as the equations are the same. th-cam.com/video/6YbjldiaP_o/w-d-xo.html
I forgot to add I have free macros on the affinity forum on color dodge and color burn: forum.affinity.serif.com/index.php?/topic/117164-dodge-and-burn-blend-mode-2-to-saturate-a-picture/
Wow, I was about to dispute your statement. Fortunately, I was wise enough to consult Dr. Google. I "thought" that I learned anything divided by 0 = infinity. Thank you for making me look this up (and fortunately, I did). Did the teaching of this change in the last million years since I was in school?

Great tip -- thanks, Espermaschine!

Thank you!
You didn't need to get dressed up for us, Dave.
Yes, I know, not the usual me. I just came out of a formal meeting. I was wearing scruffy jeans, though (ah, the pleasures of Zoom).

Thanks so much, Hans. I'm trying to understand this but must be doing something wrong -- please see forum for notes.
Have adapted many of the f64 tutorials to AP,a very informative and practical YT site for photo editing.
Diving by zero is isn't infinity it's undefined.
