photoshop workshop 1 - Quick mask mode.

Quick mask mode is useful for checking the area you have selected on your image is exact. Firstly select the icon from the left hand menu.

This will then shade your whole image red apart from the area you have selected.

Now using the rubber tool you can ensure the area selected is exact. For this select a suitable brush size an a hard edge. You also need to zoom in on the image as much as possible.

Using the switch tool on the colour icon you can choose whether to add more mask to an area or take it away.

Go around the selected area until the outline is perfect.

Now you can switch off the mask and the area will be perfectly selected. This is good for lassoing an area before copy and pasting it.
