- 1.Welcome to Boot Camp!
- Each month we will be covering basic lessons in photography such as camera settings, lighting, composition, etc
Aperture Priority 2. Camera settings:Aperture Priority Canon Cameras: Setting on dial is AV Nikon Cameras: Setting on dial is A 3. Aperture Priority Setting
- F-Stophow much light is seen, how much the aperture is open
5. Aperture Priority Setting
- You set the opening size depending on how much area you want in focus
- Camera sets shutter speed based upon how much light is being let into camera
6. Aperture = F-stop
- larger F-stop (i.e. 3.5)
- Decreaseddepth of field , i.e. image background is blurry
- Too much light, i.e. higher shutter speed.
7. Aperture = F-stop
- Smaller F-stop (i.e. 16)
- Increaseddepth of field , i.e. image background is not blurry
- Needs more light, i.e. slower shutter speed.
- HOW MUCH LIGHT IS SEEN
- Sometimes known as aperture
- Ranges from about 1.8 to 32
- A higher number (i.e. 32) means less light is seen.
- A lower number (i.e. 1.8) means more light is seen.
- LOWER F-STOP (i.e. F1.8)
- Lets plenty of light in! Better to use in darker settings.
- Less blurry since faster shutter speed may be needed to compensate for more light.
- No depth of field, i.e.background of image likely out of focus.
10. Aperture Adjustments
- Increasing the opening
- (large aperture)
- Increasing the opening lets in more light
- Make adjustments to offset too much light
- Increase shutter speed allowing less light to flow to sensor
- Decrease ISO to allow for less light to register on the sensor
- Allows less area to be in focus
11. Aperture Adjustments
- Decreasing the opening
- (small aperture)
- Smaller f-stop allows less light in
- Make adjustments to correct low light
- Decrease shutter speed
- Increase ISO to allow more light to be registered
- Allows more area to be in focus
