Increase maximum image size? [2018]

[happyrainbow]

Why is the maximum image size 300,000px x 300,000px?

Can I increase it beyond 300,000px x 300,000px?

Here are the official limiitations:

"PSD limits pixel dimensions to 30,000 x 30,000 and max size to 2GB.

PSD files are limited to 2 Gig because of the file format design and compatibility with other applications. That really cannot be changed.

That's why the PSB format was created, to allow for much larger files (in pixel dimension and total file size).

300,000 x 300,000 and 4 exabytes, which modern hardware does not touch.

PSB files work up to around 4 Exabytes, and we can't go beyond that without changing the OS file APIs to allow more then 64 bits for the file size and position."

Chris Cox (who was the senior engineer on Ps for 20 years).

Thanks!

You're welcome. It's also good for me to go over how and whys of these basics. And that's just Photoshop. If you are in PSB territory, you have to be sure third party software and output devices such as printers can handle them.

Why is Adobe the gatekeeper of my files that are going to be used in an application that accepts more than 3oo,ooo pixels?  This just seems lazy, especially if other applications will save these files, as noted by another commenter here.

Nobody is a gatekeeper. Adobe designed these formats and if a different application has different limitations, then so be it.

Adobe tools being the "standard" for professional use does make them the gatekeeper of how large my files can be.  Maybe it's time for some professionals to seriously consider the alternatives.  Sure, most people will never need more than 300,000px... but for those of who do, this becomes a serious roadblock.

I guess you'll have to use other tools, no? Adobe can't fill every need.

Unfortunately, I work in a very controlled (classified) environment, we can only install certain tools with strict government approval.  Our version of Photoshop is a special one that's made for places like this.  Because of this I also can't use the new AI-based tools in PS that would really help my workflow.  I guess I'm just out of luck.

I am an extreme Gigapixel shooter and unfortunatelt Adobe doesn't cater for this.

This 500,000px wide 360° panorama was stitched in PTGUI Pro, but Adobe was unable to process the PSB file.

I had to purchase Affinity Photo to be able to handle it.
