Review: Things to Remember
- In order to use color, you must choose a color mode that supports color, such as RGB or CMYK. You can change the color mode by selecting the Image > Mode menu.
- The Color blending mode preserves the underlying grayscale of an image and applies a hue of the selected color.
- The Clone Stamp makes an exact copy of the sampled area, whereas the Healing Brush makes a copy of the sampled area and matches the texture, lighting, transparency, and shading of the sampled pixels.
- You can set up to five clone sources in the Clone Source panel.
