Thanks for the explanation. I followed your advice and have started to understand the way the macros work.
What I was looking for was a PDF saying what macro functions for what purpose, not the explanation how it was created.

What I wanted to ask was if there is any explanation available as to what each of the 21 macros does and how to use them.

You're welcome.
I would like to thank you for sharing your knowledge and the time and effort you are taking to teach us.
Your videos serve as  a great  source to learn about photo editing and the quality of content is best among all the tutorials I have come across.
And it's good to know that I can find you here too
 

I have come across a you tube channel named "InAffinity"  which covers free tutorials for affinity photo.

What makes this channel unique from others is that the information is provided at moderate pace with logical and scientific reason behind each step.
The moderator is to the point and explains every thing in easy to understand language.
I thought I should share it with everyone and hopefully you will enjoy learning from these tutorials.
If you also know about some thing similar, please share it in the forum.
Thanks

you mean David posts on these forums too?

I have posted the link in main post and reply also. If you type inaffinity in youtube search bar, you will get to the channel too.
