These large 3000×2300px 300dpi images are made from spontaneously painted graphics and can be used to evoke excitement, fear, drama, horror or doom. But they can also be manipulated using blending modes, light and saturation, to evoke softness and mystery. The original graphics were done in monotone on large canvases to produce the maximum tonal contrasts and fine detail. The images are big enough and have such detail that you can cut them up into sections and juxtapose to make many more completely different grungy backgrounds.
The detail on the preview image is shown at 60% reduction. The screenshots give an idea of the composition and colors of each image.
