ISO, Aperture & Shutter Speed

ISO-100                           ISO-400

 ISO-1600                      ISO-6400








The ISO(in pictures above) is used to adjust the amount of noise(or grain) in the photo, it is a little harder to see in the pictures above, but the ISO-100 has less noise and is a cleaner more crisp photo whereas the image with the ISO-6400 has more noise and is less crisp of a picture with a more grainy quality.

portrait with an aperture value of f/36

In the top portrait the background is blurred because the aperture was opened wider allowing for the edges of the shot to be out of focus, whereas the lower photo has a smaller opening in the aperture making the entire image in focus but less soft, so for portraits it is preferred to shoot with a wider aperture.

These two images are demonstrations of a relatively high shutter speed of 1/1250 allowing an action shot or shot with fast motion to appear "frozen in time", w/o motion blur from the action itself.

Photography Notes

   Exposure Principles

 ~ Shutter speed :

- short- 1/1000th of a sec, long- 1 sec 

- How much information is captured

 ~ Aperture :

- wide(fast)- 1.9, narrow(slow)- 22 (smaller the number larger the opening in the aperture)

- What level of depth of field you have, changes the focus of the image

 ~ ISO :

- sensitivity to light

- 100 to approx. 6,400 or 528,000 

- higher setting is better for low light scenarios (because it lets in more light)

- low setting, no (noise/grain)

- high setting, more (noise/grain)

   Camera Settings

- auto

- no flash

- portrait -- (good for close up faces)

- landscape -- (good for large backgrounds)

- sports -- (good for in focus movement)

- macro -- (good for extremely small and close up things) 

- P = program

- TV = time value-(shutter speed)

- AV = aperture value-(aperture)

- M = manual-(aperture, shutter, and iso)

- low light mode
