Can't enter 'Filters gallery' in Photoshop
I'm kinda new to Photoshop and in a tutorial for Pin-up photography is was told to enter 'Filters gallery', but it is unavailable and I don't really know why.
I have a picture which I want to edit. Before that I made two layers by separating background from the rest of content and then I changed the layer with background to smart object and tried to access this Filter Gallery
If you choose your image mode as 16Bits/Channel or 32 Bits/Channel, Filter Gallery option will become deactive.
Here is the image (you should the color bit in title RGB/32)
