This free hires airbrush texture is taken from my upcoming hi-res airbrush texture pack, Ethereal Airbrush.
If you've ever done airbrush, you know that digital brushes for airbrush are way too uniform. They don't come even close to level of grain size and shape variation, and visual interest of the real thing. I painted this with Golden hi-flow acrylics sprayed through a Paasche Talon onto 11"x17" bristol vellum, then scanned it at 600 dpi.
I used this texture in After Effects in almost every scene in an airbrush-heavy music video I directed for Velvet Two Stripes in 2021. It has a variety of rounded gradients of different sizes and intensities, which I applied to AE shape layers with feathered masks to texture the elements in my shots. Enjoy!
UPDATE: I just released a brush set you may also be interested in Overspray Airbrush Texture Brush Set for Photoshop.
