Many people ask how I achieved the look in this image. The texture that appears to be similar to a chalk or pastel drawing comes from combining multiple exposures of slightly different images.
The images below are the 8 exposures that are combined in an editing program, using a special blending mode, to create the image you see above. Each one is moved just slightly, giving the final composition a layered, textured look.
These images are underexposed in order to create a correct exposure when they are combined.
