Basic Camera Functions Class 2 – DACC Basic Photography I Class

Basic Camera Functions Traditional Camera - Film Digital Camera – CCD and memory storage device

Advanced Modes Tv – Shutter Speed Priority P – Program Mode Tv – Shutter Speed Priority Av – Aperture Priority M – Both Shutter and Aperture set manually A-DEP – An aperture priority where camera sets f-stop according to the subject

Program Mode Camera selects both the Shutter and Aperture for you Will also let camera turn on the flash if it thinks it’s needed User chooses the ISO

Camera Controls – Shutter Speeds In Shutter Speeds, a stop is the increase of the exposure by double or a reduction by ½ Focal Plane Shutters has a “flash Sync” shutter speed

Shutter Speeds 1 sec. – ½ sec. – ¼ sec. – 1/8 sec. – 1/15 sec. – 1/30 sec. – 1/60 sec. – 1/125 sec. – 1/250 sec. – 1/500 sec. – 1/1000 sec. Digital Cameras have intermediate shutter speeds Ability to hand-hold a camera Lens mm = shutter speed

Stopping action

Let’s Look at Shutter Controls

Focal Lengths 18mm 55mm 150mm 300mm

Focal Length Changes Perspective 300mm 200mm 100mm 50mm 20mm 10mm

Aperture controls Depth of Field F- stops f-1.0 – f-1.4 – f-2.0 f-2.8 – f-4.0 – f-5.6 f-8.0 – f-11 – f-16 f-22 – f-32 The larger the number – the smaller the aperture The smaller the aperture – the greater the depth of field

Depth of Field Exp – 8 sec. – F32 – 100 ISO

Selective Focus

Camera Control - Focus Manual Focus Selecting an Auto Focus Point Focus Lock

Let’s Look at f-stops, depth of field and focus control

Film Speed ASA – ISO Lower speed needs more light – higher quality image Higher speeds require less light – stops action – less image quality Larger formats provides higher quality photos

Grain / Noise Higher speed /low light conditions = photos with electronic “Noise” Changing the ISO/ASA of your camera

Stops in Film Speeds ASA 100 – ASA 200 – ASA 400 – ASA 800 – ASA 1600 – ASA 3200+ Sunny 16 Rule Bright Sunlight Exposure Aperture = f-16 Shutter Speed = ASA of Film

Metering your Image Types of Light Meters Incident Reflective What is the Meter Looking For 18% Gray

Exposure Compensation Fooling Automation

Situations that can fool your meter

Let’s Look at Film Speed Controls And Exposure Compensation

Batteries 2 hour max for most cameras Traditional Cameras use lower power batteries that sometimes last for 6 months to a year. Digital thrives on Batteries Previews Built in Flashes Auto focus Automatic shutdown 2 hour max for most cameras
