Exr to .tiff - brighter image

I have 16bit .exr sequence. When Mocha creates cleanplate .tiff, in Photoshop it looks more brighter then original. When I edit image and save it in same file and .tiff format, in Mocha sequence with changes looks good, without brightness.
Is there any way to edit .tiff file in Photoshop in same colorspace, to see final result of retouch, not brighter version?
