Blurring backgrounds on Trigger or Button click
In the attached example, the background changes quickly to blurred using a state change when the user clicks a label below. I really want the background to blur over one half or 1 second like a real camera would pull focus, as the panel slides up over it, so that it doesn't just pop on, which is a distraction (to me anyway).
I thought using a state change would do it, but I don't see a way to control how quickly an image changes from one state to the next, unless you run it through several 'states' as an animation. That seems a bit memory intensive when done with a full background, but someone can correct me there?
I've tried different layering show/hide calls , but that is not working out either, since a 'shown' layer is always on top of the current layer and this has to happen behind everything. I saw a thread from 8 years ago about blurring programatically but it stopped 4 years ago. If anyone has this solved already, appreciate your pointing me to the answer.
I did this as an idea for the Tab challenge so if anyone wants the source PS files to use it, let me know. The two slides are just two MidJourney background ideas/choices. Thanks!
