Brush Projection distorts the current brush tip shape according to a an interactive perspective-warping algorithm. A real-world equivalent is projecting a flashlight beam with the Batman logo against a 2D plane. Using the stylus's ability to transmit tilt & bearing data, the stylus's orientation controls the projection of the bat signal on the 2D plane of the canvas.
- [Voiceover] Imagine you are in a dark room…with a flashlight.…When you point the beam directly at a wall,…a circular area of light is cast upon it.…As you angle this beam,…the circular light shape transitions to an ellipse,…due to the tilted angle of the flashlight…relative to the wall.…Now imagine painting with a brush…that distorts the captured tip in the same manner.…That is brush projection, and Photoshop can do it.…Let's project some brush tips.…
So, here we are in here, and I'm going to…use a tool…that will really highlight the look of this,…and that's down here, it's called "text".…Right here.…I'm gonna reduce the size a bit.…And interestingly, it makes the word text.…So this tool just by default…will give us a straight-on look at the word text.…Okay, let's go ahead, I'm gonna clear off the screen,…and let's open the brush panel,…and in Shape Dynamics, right here at the bottom,…you'll find Brush Projection,…so I'm gonna go ahead and turn that on,…and let's go ahead and try that.…
So now, you'll see as I rotate this around…
John begins by going over some important brush tips that many artists are unaware of: bristle, erodible, and airbrush tips. He talks about how to customize the brushes and use them to mimic natural bristle brushes, chalk, and spray paint. He also addresses some global issues such as paint flow and spacing, which can have a dramatic impact on any brush you create.
From there he jumps into some more advanced techniques, such as blending colors, loading brushes with multiple colors, and using Brush Projection. Use these tips together to extend the toolset and maximize your creative freedom in Photoshop.
