That raises the question as to why you are bothering with Photoshop at all?

You are going about things in a ham handed an inefficient way.
Adjustment layers in Photoshop are what makes Photoshop and many of the 
new OSX image editing apps such as Pixelmator, and Affinity Photo so 
powerful.

I suggest that you get yourself a good book on Photoshop, or take in a 
few video tutorials. I recommend starting with Scott Kelby's "The Adobe 
Photoshop CC Book" or Martin Evening's "Photoshop CC for Photographers" 
both are available from Amazon.

For videos I would start with Adobe and Julianne Kost. These are all free.

That should be plenty.

If you open your Photoshop preferences and check "Memory Usage" you 
will see "Available RAM". This is not going to be 32GB. it will 
probably read something like "28000 MB". The next line will read "Ideal 
range" for your 32 GB it will probably be something such as 15400-2016 
MB. I would select something within that range, probably around 18000 
MB. Don't try to allocate all 32 GB.

You need to change your methodology it is not giving you the best 
Photoshop can give you. No Photoshop user would ever recommend doing 
what you are doing.
