Basic Camera Functions Traditional

Camera -

Film

Digital Camera – CCD and memory storage device

Advanced Modes 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

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-5.6f-8.0 – f-11 – f-16f-22 – f-32

The larger the number – the smaller the aperture

The smaller the aperture – the greater the depth of field

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”

Fooling Automation

Situations that can fool your meter

Let’s Look at Film Speed Controls

And Exposure Compensation

Batteries 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
