A Photoshop swatch for recreating Anders Zorn palettes in a digital environment
A bunch of photoshop brushes mostly useful for the brushes that can be used for actual sketching and drawing (as opposed to digital painting). I use the “Classic Cartoonist” brush and the “Ultimate Inking Thick 'n Thin” brush from this set more than any other brushes. I’m always looking for thinner brushes that are bold and not like, “streaky”.
I use the edge brushes from this set in my attempts at coloring.
I use these “distressed” halftone patterns on almost everything to give it texture. You can also apply these to brush presets to give your brushes halftone edges or to give them a canvased look. These are the only patterns I use consistently in Photoshop and consider essential.
If you sketch something out but you’re zoned out and did it at a small-ish size and want it bigger but don’t want to re-draw it, you can save your line art as a transparent PNG and then run it through waifu2x.
I’ve done this a few times, and you can’t even tell it was run through a resizer.
