Then I have to tone-map again
Photoshop makes this slightly un-obvious but this is the procedure:
CS6 (or older) --) HDR Toning; select method: "Exposure and Gamma" Leave at default to keep identical image
CC (newer ) ---) In settings (preferences) you can decide if you want to use 'HDR Toning' or 'CameraRaw'.
If you choose HDR Toning, same as above, choose Exposure and Gamma. If you have few layers, it will simply ask you to merge, say no. No need to select anything.
If you select 'CameraRaw' instead, go to 'Camera Calibration' tab, and choose "2010". The default is 2012, which will try to 'equilize histogram' by default for 32bit files. It doesn't know you don't want it, it's stupid thing from Adobe.
Gamma: 3dsMax 2013 and older : 1.0
3dsMax 2014/2015: Automatic (which is 1.0 for 32bit OpenExr./Hdr.)
{note: The first time you use CameraRaw, it will clamp the image, so you will loose dynamic range, and cannot do actual tonemapping second time, even if you stay in 32bit mode. You will simply be in linear mode, with 32bit color depth, but with clamped file, so you might as well just go lower to non-linear 8/16bit and continue post-production there}
