16bit renders

Hi there guys, I was wondering, can you render an image in 16bit colour space?

Many thanks

After rendering you can save your image in different image-formats like BMP, SGI, RGB, TIF(F) and OpenEXR. All are 8-bit except for the 24-bit EXR.

If you save as EXR you get a 16-bit floating point image.

To put it another way, TG2 always renders in HDR. It isn't until you save that you choose what the dynamic range of the saved render will be.

Regards,

Jo

Really? Photoshop shows it's a 24-bit image. It has an asterix next to "24-bit" in the filename when opened though. Not sure what that means then.

might be 16bit plus 8bit alpha?
Not sure though

The alpha-output is separate in the render-node...?

Funny, my Photoshop actually shows 32/bit channel.

Me too. Maybe it's a Photoshop bug?
