Let’s review some basics of the instrumentation. You’ll have your on and off switch, your camera screen, your lens cover, the joy stick with the height adjustment ring, the chin rest, the light adjustment knob, the focusing adjustment knob, and the lock. Some models will have a diopter compensation knob. Let’s also take a moment to review the optos, another imaging instrument. So, this instrumentation includes the device, handgrips, the touchscreen with prompts, that allow for auto capture and manual capture.
