Adobe default is to open Raw files in 8 bit

I'm getting a bit lost here (but that isn't important).

The issue is that the file needs to start in a 16 bit environment and stay in it all the way through until it is finished, if you want to retain maximum detail and tones.

The video above also shows a way to process in 32 bits.

But I haven't actually tried that. It clearly produces very large files - 170 mb for the first layer - based on my one attempt at trying to understand the method.
 
I think the video is actually in two parts:

- Creating an image in 32 bit

- processing it
 
The 16-bit vs. 8-bit struggle is real. I've found sticking to 16-bit from the get-go does help maintain those sweet details. As for the 32-bit process, it does churn out hefty files, right? Maybe worth experimenting, but definitely keep an eye on file sizes – no one wants a monster file to compress JPEG.
 
My files are always defaulted to 16 bit. I have never come across 32 bit anyway perhaps the reason being I don't delve into PS that deeply. If you think the files are too large to work upon why not change them to 8 bit before you start work on them? I change them to 8 bit after I have finished what I need or want to do and save them as jpg that way.
