Richard Harrington has developed a following for his clear explanations and patient presentation of the intricacies of Photoshop and other Adobe apps.
For those creatives who haven’t sat in on one of his classes, or read one of his many Photoshop books, Richard Harrington should be on your must meet list. His clear, straight forward prose has helped many navigate Adobe’s Photoshop and Creative Suite (CS), especially as used for video production.
Here are two ways to get some sense of what Richard teaches: Adobe has made a collection of his tips–it’s actually a 47-page PDF–about using CS 5 for DSLR production available here. Meanwhile, his website–which features new tutorials on a regular basis–can be found here. Highly recommended.
