Having seen the subsurface images by Chirag Jindal in the IPE my attention was captured by another image, but on a different scale. This was the use of infrared photography to look beneath the surface of this Leonardo masterpiece at the National Gallery in London. It revealed unseen images under the surface of The Virgin of the Rocks.
Just like Layers in photo editing software artists leave details not visible in the final image. An application where photography informs us of fine art, rather than be the art in itself.
It is in information like this that I find real value in photography. What do you read into images?
