After merging my bracketed images into a 32 bit file I used Nik HDR Efec Pro 2 to tone map it. But the returned picture has nothing to do with the image I saw in HDR Efex.

1. The merged 32bit image

2. The picture in HDR Efex

3. The HDR Efex picture in Photoshop CC

It probably has less to do with the computer and more to do with the 32-bit exposure setting - it's probably set differently between the systems. 32-bit files contain more data than your monitor can ever display. The 32-bit exposure slider lets you 'preview' tonal data you have to work with.

This slider only affects the on screen preview. You're not tone-mapping the image at all with this slider. If you want to control how you image appears, use the tone mapping features in Photoshop or Camera Raw to produce a 16-bit or 8-bit image for your screen or print.
