This document provides an introduction to aperture priority camera settings. It explains that aperture priority allows the photographer to set the f-stop or aperture opening size, while the camera selects the shutter speed based on the amount of light. A lower f-stop number means a larger aperture opening that allows more light in and a shallower depth of field, while a higher f-stop means a smaller opening, less light, and greater depth of field. It discusses the advantages and disadvantages of different f-stop settings in terms of light levels, shutter speeds, depth of field, and image focus.

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-Stop

4. F-Stop how 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) ADVANTAGES Decreased depth of field , i.e. image background is blurry DISADVANTAGES Too much light, i.e. higher shutter speed.

7. Aperture = F-stop Smaller F-stop (i.e. 16) ADVANTAGES Increased depth of field , i.e. image background is not blurry DISADVANTAGES Needs more light, i.e. slower shutter speed.

8. F-STOP 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’.

9. F-STOP LOWER F-STOP (i.e. F1.8) ADVANTAGES 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. DISADVANTAGES 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

12. F-STOP IMPACT Large aperture Small aperture
