White tempura and acrylic paint on black canvas, left in the sun for 2 months, then rolled and cracked to perfection! Shot on the A7r II with the Voigtlander MACRO APO-LANTHAR 65mm f/2.
I output a few of these textures with the paint value at white, which works well for multiply mode and masks. A few others were balanced to have an average value of 50% grey, which are better for the “contrast” blend modes like overlay, soft light, etc.
Bonus – try using Grunge 200 on Hard Light mode in Photoshop or After Effects on any illustration for an instant vintage painting look:
