Oh course it's a bug! It's a BEE! *Batum tss* (Sorry, couldn't resist.)
In all seriousness, I do think the thread makes a good point. Some of these effects cost spells or can only be used once per long rest. So disabling them for a picture in photo mode can be annoying. It does feel odd that the option to remove those types of visual effects isn't included. Then again, it's such a massive patch that I feel it's understandable a few things may have been overlooked here and there.
Have you tried saving the game, disabling the active buffs, taking the pictures, and then reloading? I know it's annoying having to do all that, but until an actual fix comes, if it does come at all, there may not be many other options.
Looks like they are going full speed ahead with their next unannounced project, so not sure if they're gonna go back and patch this.
I don't think this is practical. For instance, Shart has a ring that gives her temporary HP when she heals someone. So she runs around quasi constantly with a white shimmer around her. I would have to somehow get rid of those temp hitpoints to make a decent photo. And then somehow get them back to go on with the adventure.
