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. </p>

like the regular color picker does with 8‑ or 24‑bit images. Click
in the color field to select a color and move the color slider to
change hues, or use the HSB or RGB fields to enter numeric values for
a particular color. In the color field, brightness increases as
you move from bottom to top, and saturation increases as you move
from left to right.</p>
<p>Use the Intensity slider to adjust the
brightness of the color. The color value plus the intensity value
are converted to 32‑bit floating point number values in your HDR
document. </p>
</div>
<ol><li class="stepexpand"><span>Select a color by clicking in the color field
and moving the color slider, or by entering HSB or RGB numeric values,
as in the Adobe Color Picker. </span></li>
<li class="stepexpand"><span>Adjust the Intensity slider to boost or reduce the color’s
brightness. The new color swatch in the Preview scale at the top
of the color picker shows the effect of increasing or decreasing
stops for the selected color.</span> <p>The Intensity Stops correspond inversely to exposure
setting stops. If you boost the Exposure setting of the HDR image
two stops, reducing the Intensity stops by two will maintain the
same color appearance as if the HDR image exposure and the color
intensity were both set to 0. </p>
<p>If you know the exact 32‑bit
RGB values for the color you want, you can enter them directly in
the 32‑bit value RGB fields.</p>
</li>
<li class="stepexpand"><span>(Optional) Adjust settings for the Preview area.</span> <dl><dt class="dlterm">Preview Stop Size</dt>
<dd>Sets the stop increments for each preview swatch. For example,
a setting of 3 results in swatches of ‑9, ‑6, ‑3, +3, +6, +9. These
swatches let you preview the appearance of your selected color at
different exposure settings.</dd><p class="dlseparator"></p><dt class="dlterm">Relative to Document</dt>
<dd>Select to adjust the preview swatches to reflect the current
exposure setting for the image. For example, if the document exposure
is set higher, the new preview swatch will be lighter than the color
selected in the color picker’s color field, to show the effect of
the higher exposure on the selected color. If the current exposure
is set to 0 (the default), checking or unchecking this option will
not change the new swatch. </dd><p class="dlseparator"></p></dl>
