Selecting Colors Multiple ways to

select colors:1. Swatches – Preset

Colors2. Color – Spectrum 3. Eyedropper – Copy

color from another part of the picture or from another picture

Retouching Images Many ways to retouch images:

1. Clone stamp tool2. Spot healing brush3. Healing brush4. Patch tool

Clone Stamp Tool Lets you replace the pixels in one are

of the image by sampling it from another area of the image.

You can also use this tool to alter the image.

Spot Healing Brush Paints pixels with sampled pixels and

matches the texture, lighting, transparency, and shading.

Unlike the clone stamp, the spot healing brush automatically samples from around the retouched area.

Healing Brush Like the clone stamp you pick the

area of the picture to use as a source (Alt click)

The difference is the healing tool will try to match the texture, lighting, transparency, and shading

Patch Tool Use the patch tool to replace a

section of the image. Select the section to be replaced (like

the lasso tool) Move the cursor around the picture until

you find a suitable area to use as a replacement
