• Cold Pixels – To enable or disable the display mode of absolutely black pixels, click the
triangle on the left and the histogram is clipped on the left side. Absolutely black pixels will

be displayed in bright blue in the image. Cold pixels (in blue) indicate areas where black
has achieved maximum concentration (a zero value).

• Hot Pixels – Clicking the triangle on the upper right will show where your image is
completely white, where the histogram is clipped on the right side. Absolutely white pixels
are displayed in red.

In both cases this can be problematic (especially for printing) as there is too much ink coverage for
cold pixels and no details at all in the hot pixels. These indicators are a sign that you should adjust
the exposure of the image. You may want to leave the Histogram panel open as you work, because
it is an easy way to learn to read the graphical details of a digital image.

NOTE
The use of the Develop and RAW Develop filters are an excellent way to take control of the Black

and White points as well as the Shadows and Highlights of an image. Pressing the J key will also
toggle the clipping indicators On and Off if you want to see the pixels underneath.

Layers

Layers are a powerful way to “build up” your images, with different enhancements and use of
blending modes on each layer. Using layers, you can apply corrections or enhancements on
different layers, and experiment until you achieve exactly the look you’d like for your image.

• To create a new layer.

Click on the + button in the
Layers Toolbar header. A small
pop-up menu will appear giving
you the option of creating a

layer using one of two options.

Use an Adjustment Layer to
create a layer to which you can

apply a preset or any other
adjustment in the Filters panel.
The Add Image option will
show a standard Open File
dialog, allowing you to create a new layer with a texture file or another image that you’ve

chosen.
