Once upon a time, so I’ve been told, a certain British landscape painter made field studies on his actual thumbnail (hence, the term). Has anyone else heard this?
It’s an intriguing idea and I suggest looking at your thumbnail right now and thinking about how you could break the space into a few major areas to express a composition in a simplified manner.
Now doesn’t that make a 1″ x 2″ study seem big?
Thumbnails are fast and tiny shorthand drawings that artists use to test and develop ideas.
They let you explore multiple options without pressure; in just a few minutes you can experiment with composition, subject, format, or colors.
You can “use your words” and write comments along side of your thumbnail sketches.
Usually thumbnails are done as a group.
There are no rules on how to make a thumbnail sketch.
Use any media that inspires you.
Have at it, and let me know how it goes!
