NEVER MIND I was reading that a work-around for Photoshops bit limits (for example, can't use most filters while in 16 bit mode) was to use smart objects. I haven't done much with smart objects. This is what was written: "Use smart objects to run a filter on a 8 bits layer that resides in a 16 bits files. (copy layer, convert to SO, open SO, convert to 8 bits, convert to SO again, run filter, close SO.)" huh? Questions 1: Is it possible to have an 8 bit layer in a 16 bit file?? If so, how? 2: I can open smart objects (new files, it seems), and covert to 8, filter what I want - and then how do I close it and get it back into the original? The article I'm quoting is from 2008 so no chance I can ask what he meant, and my google skills must suck cuz I can't find anything.
