The purpose of this assignment was to test how different aspects of a camera, such as F-Stop and Shutter Speed, affect the photo’s depth of field. We started off with a low aperture and a high shutter speed to capture an image with a shallow depth of field. We were asked to take photos of an object starting off with a very shallow depth of field and progressively make the image have a greater depth of field. For each photo we increased the aperture and decreased the shutter speed to create a greater depth of field. The ISO and focal length remained the same in all of the images because they didn’t affect the depth of field in this case.

My group worked well together and took turns taking the photos. We did a good job at capturing the change in the depth of fields in the images above.  For each photo we increased the f-stop and lowered the shutter speed as instructed and overall did well at displaying various depths of fields.

1. What is exposure?
a. Exposure is the amount of light that is let in when the picture is taken.
2. What are aperture, shutter speed and ISO?
a. Aperture is the clearness and focus of the picture
b. Shutter Speed is how fast the shutter closes capturing the action or freezing the action
c. ISO is this is how grainy the picture is also the amount of light that goes in
3. When would you need to change your ISO?
a. You would change your ISO when it is too sunny or when it is cloudy
4. What are “stops”?
a. The “stops” are the f stop which is the aperture
5. What is “noise”?
a. The “noise” is referring to ISO which higher ISO could cause a grainy.
6. What are aperture and shutter priority settings and when would you want to use them?
a. The aperture priority is where the ISO and the shutter speed are chosen by the camera to fit your picture best and you only control the aperture which is the depth of field. Which is represented with an A on the camera settings.
b. The shutter priority is where the ISO and the aperture are chosen by the camera to best suit your picture and you control how fast or slow the shutter speed is. Which is represented by the S in the camera settings.
c. You could use the Aperture priority when you want to take a portrait and blur out the background. You could us the Shutter speed priority when you are taking fast action shoots that you want to freeze the actions or when you want to capture all the action in a movement.
7. What are AF modes?
a. The AF modes are one shot AF, Servo AF, and AI Autofocus. The one shot AF is where the focus is lock on the subject you chose when you half press the button to take the picture (it stays locked as long as you have it half way pressed). The servo AF is when the picture is refocusing constantly this is great for sport events. The al autofocus is will automatically from one shot AF to servo AF it will detect movement in the fame.
8. What is white balance and why would you need to change it?
a. White balance is the process of removing unrealistic color cast so that objects appear white.
b. I would need to change it because the picture comes out to blue or orange or yellow.
9. What are drive modes and metering modes?
a. Drive modes are the different camera shots you can take like how many pictures you can with one click of the shutter button.
b. Metering modes are the way that the camera determines the exposure.
10. What is exposure compensation?
a. The Exposure compensation is a plus/minus scale that tells your camera to decrease or increase the exposure.

Exposure- is the amount of light the camera receives on a photosensitive surface.

Aperture- make the picture come out either sharp or grainy and it is also the amount of light that the camera intakes or is exposed to. F stops are the lens focal length, the larger the F stop the more the camera will only focus on one item and blur out the rest, creating a shallow depth of field. The lower the F stop is, the more focused the picture will come out, creating a great depth of field.

Shutter speed- is how long the camera keeps the lens open for the picture, which determines how much light the camera is exposed to. The faster the shutter speed is, the more still a moving object will appear in the photo.

 

ISO-The exposure meter tells one if the image is revealed to too much or too little light. A high ISO causes the picture to come out grainy, so its best to avoid using it.

Exposure: is how much or how little of something you want in your picture. Depending on what you want to be exposed you have to be mindful of

Aperture: is how much you want to focus on a certain object, or scenery. The higher the aperture the more it focus’ on one specific thing and blurs everything else out. The lower the aperture the more it focus’ on the entire setting nothing gets blurred out.

Shutter speed: is when you want to create a type of illusion of movement or when something is in thin air. The higher the shutter speed, the better you will capture an image as if you were frozen in time. The slower the shutter speed it seems a bit blurry due to the illusion of motion.

ISO: is like the quality of the picture itself, if its clear and detailed or grainy and unable to give specific detail. The higher the ISO the clearer the vison or photo. The lower ISO the more grainy the photo will seem.
