I read your tut on HDR images 32 bit. Here's the question, if the image is 32-bit and the monitor is 24-bit is the preview I'm seeing accurate?
To answer your question, no. The initial 32-bit preview you see may look too light or too dark because of the differences in bit depth. A 32-bit image will have a tonal range that exceeds the tonal range of a 24-bit monitor making the preview impossible. Right? To compensate for this inevitable problem, Photoshop has provided a preview adjustment feature that re-maps the image values to fall within the range of viewable pixels. These Preview settings are stored within the file and will be applied everytime the image is opened in Photoshop. No, don't worry, the Preview adjustment is used only during previews and won't change the original pixel values. Don't mess with my pixels.
Open a 32-bit image.
Choose View > 32 Bit-Preview Options
The 32-Bit Preview Options dialog box opens.
Choose Exposure and Gamma from the Method: section.
Click and drag the Gain and Exposure sliders to change the contrast and brightness of the Preview.
When you're satisfied...
