Camera RAW 15 causes large psd files

[Arseniy_S]

Hi!

I have noticed that after installing Camera Raw 15.1 with my PS 2023, the psd files that I usually save duing my work became 3-4 times larger in size, and the save time of psd files became very slow. Usually my files are around 100-150mb, but after they became 400-500mb. Originally I thought it had something to do with the PS version, but after doing several tests and trying different settings, I realized that downgrading to Camera Raw 14.5 was the solution for my issue. My psd files went back to the original smaller size and the save time of psd files became a lot faster.

Something that I wanted to bring up and see if anyone else experienced this issue.

I am currently using PS v 24.1.1 on macOS Ventura 13.2.1.

Camera Raw is currently on version 15.2. Do you see the issue after updating?

In your workflow options (at the bottom of the GUI), do you have it set for 16-bit instead of 8-bit per color? That alone would double the size after rendering and what you end up with in Photoshop. 

Are you viewing the 'size' of the various documents in the Mac Finder or what PS reports (the latter isn't especially accurate).

I went ahead and updated to 15.2, and tried again, but ended up with the same result

BUT

after reading @TheDigitalDog's comment, I checked the bit mode and realized that my old files were indeed saved in 8 bit with camera raw 14.5, and camera raw 15.2 had 16 bit as the default setting. So after changing the setting in camera raw 15.2 to 8bit, it was saving files in smaller size again.

Thanks so much for your help guys!
