Photoshop: Creating Brushes

I was taught how to create new brush presets using images and how to edit my regular brush settings, so I made a monkey rubber. A brush can only be made from a black and white image and you must select it and click edit, then new brush preset. This works for both making a new brush and rubber.

We also went over some quick methods of thumbnailing things by blocking in foreground, mid ground and back grounds in using blacks and grey tones. Giving ideas for perspective and depth. 

Note:

Familiar objects or people can be a good and easy way to set perspectives and distances in thumbnails.
