Title: 32bit PSD vs 16bit PSD
Post by: Jikkk on November 28, 2018, 12:02:07 pm
Hey,
It's still confusing me why 16bit PSD has been added while 32bit one has been existing already? Isn't 32bit better than 16bit?
Thanks :)

16-bit images have much higher precision than 8-bit images (65536 vs. 256 values per channel). While the difference may not immediately seem obvious, as e.g. the dynamic range is the same, you gain a lot more flexibility in editing with 16-bit, and a lesser likelihood for artifacts.
32-bit has even higher precision, but at the cost of significantly increased file size. Also, many editing operations in Photoshop are not supported in 32-bit mode.

In many ways, 16-bit is a great “working” color mode.

Just to echo the above.  You rarely need 32 bit for editing post, nor will you run into issues editing 16-bit.  It's just one of those things where the perceived value of 32 bit is much higher than it really needs to be.  I can't really think of many instances where 32 bit is actually needed.
