To increase the alternate Loupe magnification: m Press Command-Shift-Plus Sign (+). Press these keys repeatedly to increase magnification more. To decrease the alternate Loupe magnification: m Press Command-Shift-Minus Sign (-). Press these keys repeatedly to decrease magnification more. Showing Hot and Cold Areas in Your Images Images may occasionally have overly bright areas where color information about the area is beyond the standard limits of the Aperture working color space. For example, white areas in an image brightly lit with direct sunlight, or bright flashes off a water surface, may be so bright that their color is outside the working color space. In addition, images may occasionally have black areas where color information about the area is below the standard limits of the working color space. Aperture can display these "hot" and "cold" areas of an image with tints on the image to help you identify hot and cold areas. You may be able to adjust these areas and recover highlight and shadow detail identified by the hot and cold area overlays by changing the exposure, the recovery, the black point, or the gamma setting of the image. To show the hot and cold areas in your images: m Choose View > Highlight Hot & Cold Areas (or press Shift-Option-H). You can also monitor color clipping per color channel when performing specific adjustments using modifier keys. For more information, see "Using Modifier Keys to Identify Color Clipping" on page 342. You can adjust the threshold or sensitivity of the hot area overlays. By default, the threshold is set to 100%. You can set Aperture to flag pixels that are near the 100% mark by lowering the threshold in the Preferences window. To adjust the hot area display threshold: 1 Choose Aperture > Preferences, or press Command-Comma (,). 2 In the Preferences window, click Appearance. 3 Drag the Hot Area Display Threshold slider to the left to increase its sensitivity to highlight pixels, and drag the slider back to the right to decrease it. You can also adjust the threshold or sensitivity of the cold area overlays. By default, the threshold is set to 0%. You can set Aperture to flag pixels that are near the 0% mark by increasing the threshold in Preferences. 190 Part II Photo Editing

Showing Hot and Cold Areas in Your Images
Images may occasionally have overly bright areas where color information about the
area is beyond the standard limits of the Aperture working color space. For example,
white areas in an image brightly lit with direct sunlight, or bright flashes off a water
surface, may be so bright that their color is outside the working color space. In addition,
images may occasionally have black areas where color information about the area is
below the standard limits of the working color space. Aperture can display these “hot”
and “cold” areas of an image with tints on the image to help you identify hot and cold
areas. You may be able to adjust these areas and recover highlight and shadow detail
identified by the hot and cold area overlays by changing the exposure, the recovery, the
black point, or the gamma setting of the image.
To show the hot and cold areas in your images:
m
Choose View > Highlight Hot & Cold Areas (or press Shift-Option-H).
You can also monitor color clipping per color channel when performing specific
adjustments using modifier keys. For more information, see “
Using Modifier Keys to
Identify Color Clipping
” on page 342.
You can adjust the threshold or sensitivity of the hot area overlays. By default, the
threshold is set to 100%. You can set Aperture to flag pixels that are near the 100%
mark by lowering the threshold in the Preferences window.
To adjust the hot area display threshold:
1
Choose Aperture > Preferences, or press Command-Comma (,).
2
In the Preferences window, click Appearance.
3
Drag the Hot Area Display Threshold slider to the left to increase its sensitivity to
highlight pixels, and drag the slider back to the right to decrease it.
You can also adjust the threshold or sensitivity of the cold area overlays. By default, the
threshold is set to 0%. You can set Aperture to flag pixels that are near the 0% mark by
increasing the threshold in Preferences.
