Reference photos for tonal drawing
Photos of simple shapes in harsh lighting, suitable for practicing tonal drawing and as lighting references.
Maybe I’m just not great at googling, but I always had trouble finding photos of simple shapes like balls and cubes that I could use to practice tonal drawing. So I made these shapes out of white Play-Doh, used a spotlight-type desk lamp to light them, then converted the result to grayscale. Use them freely in your own drawings.
