Does Photoshop not support 16-bit or higher?

I imported a 16-bit PSD file in version 4.2.08.. but,

"Unsupported PSD color depth. PSD files must use 8-bit color depth."

I'm working on a 16-bit image. Can't I use the PSD import function?

You'll need to save your PSD as 8-bit per channel. It would be very rare for 16-bit images to be used with a game toolkit.

Nate Oh, I see. Thank you for your answer. 🙂
