- DSLR means Digital Single Lens Reflex
- It resembles a 35mm film camera
- They have detachable lenses
- Prime lens are only used for one focal length
- Zoom lenses are used for variable focal length
- 21 mm= extreme wide angle
- 21-35mm= wide angle
- 35-70= normal
- 70-135= medium telephoto
- 135-300+mm= telephoto
- Zoom and focus are 2 different things
- ISO= number that describes film’s sensitivity to light
- High ISO value means the sensor will be more sensitive to light, meaning it will take less light to get the right exposure
- more available light = lower ISO
- less available light = higher ISO
- Use the lowest ISO you can to avoid grain/noise
- Shutter speed is how long the shutter is open
- The faster the action is you want a hight shutter speed
- Tripods are used when shutter speed is less than 1/ of a second
- Aperture also known as f-stop (fraction) is the focal length divided by lens diameter
- Smaller number actually represents a larger opening
- Full Auto (green rectangle)– camera set in the right mode for you
- Av (Aperture priority) – you choose aperture, camera chooses appropriate shutter speed
- M (Manual) – you choose EVERYTHING
- CA (Creative Auto) – camera does almost everything lets you choose brightness, depth of field, picture style
