Photoshop CC 2015 is clamping my 32-bit images when I save as. EXR.

Photoshop CC 2015 is clamping my 32-bit images when I save as. EXR. If I re-record my HDRi heaven where the Sun is above + 16 intensity, Photoshop is tightening this value up to + 16. All right when I save as .hdr.

How to reproduce:

Create a 32-bit document

Fill the document with white which has intensity + 20

Save it as .exr

Close everything in Photoshop

Open the .exr image.

+ 20 is now + 16.

Some programs even read the new value of + 16 0. It's like Photoshop is corrupt all that is + 16.

Please fix this.

I guess what you mean by + 16 16 stops, either 216. I see that you have some very large floating point values in this file. What happens here is that Photoshop works in 32-bit mode floating-point, but OpenEXR is usually 16-bit floating point. Usually, that's fine, but this does not mean that the maximum value recorded in a typical EXR is 'only' 65504.0. Your file goes much higher and crashes is when registering.

In Photoshop, you should be able to record higher values in an EXR using "PXR24 on 32-bit", although it doesn't seem to work for me, at least on CS6.

Your other option is to download the free EZ ProEXR, which gives you the ability to read and write an EXR. really 32-bit
