What Naming Convention Do You Use For Your Coin Pictures?

when you take picture of your coins how to you name them?

For example, for me I give the first picture (always Obverse)the main description.
Such as: '2021-W ASE proof.jpg'

then for the Reverse I use the exact name but add the number '1' to the end
Like this: '2021-W ASE proof1.jpg'

Any other pics I take for the same coin I increment the number '2', '3' etc.

This way my coin pictures are always filed together in a group

And I can always know which pic by file name is the obverse and reverse without needing thumbnails.
