Dither filter no longer avaliable?
I have a file from 2022/23 where I created a template for images, and was using the dither filter. I’ve opened up this file now in my 2026 version of Photoshop, and when trying to apply this filter to a new image I’m met with an error icon and the text “Filter not avaliable or cannot be applied to this document”.
The effect is still applied to the older image, but toggling the dither filter on and off will not reapply it. (I am also unable to edit the smart object to simply swap out the image)
I’m just wondering if the filter was removed, or if something is going wrong. If it was removed, what would be a suitible replacement? I’m just unable to find anything about this.
