Core Photo
System
Color
photographs taken with the Model 350 Core Photo System are used for a permanent
record of the whole core appearance and are usually made before any sample
plugs are taken. The photographs
provide a method to view the core remotely for lithologic interpretation. A single piece of whole core or five full
boxes can be photographed in one frame.
Generally, two white light photos and one ultraviolet light photo are
taken. The white light photos are taken
one dry and one wet. The core is wet
with water from a spray bottle to make the surface colors and features stand
out.
Ultraviolet
light causes florescence of some of the crude oil components so that crude
residue on the core surface is visible in UV photographs. The UV photos are taken with the core dry.
This
system provides a stable mount for the camera, strobe lights, and ultraviolet
lights. The camera is mounted on a
swing-down arm that is counterbalanced and motion damped so that camera
settings can be made without changing the view. The framework is mounted on tracks so that it can be moved from
one setup to another on each end of the layout table for faster
processing. A black felt mask and
plastic annotation letters are provided.
A
room that can be made totally dark is required for the ultraviolet photos.
