SHARPEN using BLUR? Is it even possible? AFFINITY Photo tutorial on how

Today a very interesting technique i came across which has it's origins from Dan Margulis.It makes so much sense that i am amazed why i hadn't thought of this before :)
I am going to share how you can apply this method in the Affinity Photo way and as a bonus i am going to give you some tips how to even improve you document setup.

Despite the number of steps and is a bit messy, the final result it is worth. Thank you for teaching!

Clever but oh so complex

[@Graphicalfinity]

Indeed... Definitely not for a quick sharpen action :)

Whaouuu ... What a crazy method ! .... This video is a little tresuare for me .... (THANK YOU)² very very (MUCH)²

this works but the file size will be large and you used a gaussian blur. I have been using bilateral blur ( inverted) for years to sharpen as it preserves edges I built a macro (available on the Affinity forum) that only requires 1 file duplication rather than 6. Bilateral blur works better than gaussian blur. It is interesting to note that the frequency separation tool in affinity uses a very similar technique using gaussian blur but they recently added bilateral blur and median blur as choices. IF you want to use gaussian blur, I would venture that the affinity tool is much easier to use than the method you describe and ;has similar results.

Thank you for sharing. In the latest version of Affinity they indeed added more options to High Pass (and if i am not mistaken, the high pass also has been added as a live filter)

just came across... it's an ancient trick - It's actually a technique taken from master painters, then photographers learned to do it, then it showed up in Photoshop, etc.

[@Graphicalfinity]

👍 Thank you for the background info. If you have a link on how the master painters applied this trick, please free to share it.. I am very interested how they applied this technique :)

[@maze400]

Could you make a macro out of the entire process?

[@Graphicalfinity]

Thanks! I'll look into it..

[@BlackWipeout]

Bad news, you can't move layers with macro :(

[@maze400]

@@BlackWipeout No but I think you could record the process up to the point where all that is left is to move them to the top could be done.

This is way too complicated... Too many steps with significant changes, but interesting too know about it

[@Graphicalfinity]

I agree, it is interesting how the blur effect can be used in this way.
