To adjust HDR image viewing
The dynamic range of HDR images exceeds the display capabilities of standard computer monitors. When you open
an HDR image in Photoshop, it can look very dark or washed out. Photoshop lets you adjust the preview so that the
monitor displays an HDR image whose highlights and shadows aren’t washed out or too dark. The preview settings
are stored in the HDR image file and are applied whenever the file is opened in Photoshop. Preview adjustments don’t
affect the HDR image file, all the HDR image information remains intact. Use the Exposure adjustment to make
exposure edits to the 32-bits-per-channel HDR image.
