Creative Suite Session: Photoshop

When opening a photo into PhotoShop directly from a digital camera is generally opened in RGB mode. The range of colours available is far more vast when working in RGB. When the image mode is converted to CMYK, the colour changes and becomes less vibrant in some circumstances. RBG is Photoshop's default mode. RGB files are smaller and also all of Photoshops calculations are focused around working in RGB.

Original Image: RGB mode

When selecting proof setup we are given a preview of working in CMYK. There are also various RGB view modes to work in too.

The final way to work with spot colours.

Working with channels

Each channel is a grayscale image specifying different areas of light and shadow.

This is shown when viewing channels in specific combinations such as cyan & magenta or magenta & yellow.

Grayscale images work with one channel only.
