mass update photoshop -> third-party_edit
remove alias photoshopped -> photoshop
remove implication nude_filter -> photoshop
The photoshop tag is kind of a mess. It's constantly muddied by people adding pictures to it that don't belong and were simply just created using the program by the artist itself, mostly because of translated tags from sites such as tumblr, and also because it's not immediate what it stands for. It might have been the case 10 years ago, but today third party edits are not always (or even necessarily often) done with photoshop - having the third-party_edit umbrella tag be named after a specific program only serves in confusing new users and making gardening unnecessarily complex.
After/if this is approved, I'll go through the tag and move the applicable images to something like photoshop (medium). The photoshop tag will instead be left empty to facilitate tag gardening in case of people not aware of the change deciding to use it.
Once this is approved I'll ask for a reimplying/realias (it seems I can't as long as "photoshopped" is already aliased), because asking all of it in a single request messes with how bulk requests are processed. Once/if these are approved I'll also open an issue on github to change the part of the code that makes the photoshop tag stand out in the mod queue.
It's worth keeping "photoshopped" aliased for both an autocomplete reason and because this term is unequivocably tied to third party edits, unlike the name of the program by itself.
EDIT: The bulk update request #1561 (forum #145125) has been approved by @Hillside_Moose.
