of the image preview.

You can also adjust the preview of an HDR image open in Photoshop by clicking the triangle in the status bar of the
document window and choosing 32-Bit Exposure from the pop-up menu. Move the slider to set the white point for
viewing the HDR image. Double-click the slider to return to the default exposure setting. Since the adjustment is made
per view, you can have the same HDR image open in multiple windows, each with a different preview adjustment.
Preview adjustments made with this method are not stored in the HDR image file.

About the HDR Color Picker
The HDR Color Picker allows you to accurately view and select colors for use in 32-bit HDR images. As in the regular
Adobe Color Picker, you select a color by clicking a color field and adjusting the color slider. The Intensity slider allows
you to adjust the brightness of a color to match the intensity of the colors in the HDR image you’re working with. A
Preview area lets you view swatches of a selected color to see how it will display at different exposures and intensities.
