Chronochromagraph (CCG) refers to the process of creating photos that appear to be layered in PS, but are in fact put together in camera with minimal use of PS for editing. This is achieved with the use of long exposures (usually in bulb mode) and tightly controlled lighting(snoots, barn doors, etc...). The advantages of a CCG are many. To name a few, you can change focus points, aperture and even swap lenses DURING a shot. You can change locations, use forced perspective on a level unheard of before and place objects in/on other objects. All in a single exposure.
Types of Chronochromagraphs:
July, 2017: Static CCGs uses tightly controlled flash to illuminate a scene piece by piece.
Hybrid combines use of flash with constant light.
Fluid CCGs use constant light to illuminate subjects. The result is a photograph which is "painted" using the human body as the brush.
Any CCG that is shot outside of the studio - in whole or in part - is an environmental Chronochromagraph.
Some techniques exclusive to the Chronochromagraph:
Multi Location Imaging (MLI)
MLI is a CCG in which one imprints scenes from different locations on the camera sensor. One common use for this technique is to place people/objects in impossible locations.
Especially useful for Multi Location Images. (MLIs)
Especially useful for forced perspective and Multi Location Images. (MLIs)
Great for hyper shallow depth of field. Better for selective focus than a Lensbaby. Many uses.
