ISO

Leave a comment

ISO measures the sensitivity of the light sensor,  which is responsible for gathering light and transforming it into an image. The lower the number the lower the sensitivity of the film and the finer the grain in the shots you’re taking. In darker situations a higher ISO setting is used to get fast shutter speeds.

ISO Speed Example:
ISO 100 – 1 second
ISO 200 – 1/2 of a second
ISO 400 – 1/4 of a second
ISO 800 – 1/8 of a second
ISO 1600 – 1/15 of a second
ISO 3200 – 1/30 of a second

The ISO sequence is: 100, 200, 400, 800, 1600, 3200, 6400 and etc. Each step between the numbers effectively doubles the sensitivity of the sensor.

Black and white tone experimentation

Ansel Adams zone system

The Zone System, was a system of distinguishing between various black to white tones within an image. It provides photographers with a systematic method of precisely defining the relationship between the way they visualize the photographic subject and the final results.

Here are some photographs I have edited in Adobe Photoshop with the Ansel Adams Zone tonal system in mind.

Camera Skills :Exploring exposure

Leave a comment
  • In this shoot we used different white balance (shady) along with an ISO setting of 200 and a variety of shutter speeds in order to investigate what exposure does and how it affects a photograph.
  • An image taken with a  high shutter speed allows less light to enter the camera but an image taken with a low shutter speed allows more light to enter the cameImage result for shutter speedsra.

Camera Skills : Looking at the exposure triangle

The Exposure Triangle

  • The exposure triangle is a common way of linking th
  • Image result for what is the exposure trianglee three variables that determine the exposure of a photograph.
    • The three variables are aperture, shutter speed and 
      ISO.
    • Aperture is a measure of how open or closed the lens’ iris is.
    • Shutter speed is how long the shutter remains open and so how long the lens is exposed to light for.
  • The three variables in the triangle work together to give you the photograph that you want.

what is exposure

Leave a comment

Achieving the correct exposure is based upon that of the rate o flight is uncontrollable, three factors remain under your control:

1)the cameras(lens) width, 2)the duration you leave it in then(exposed to light),3)and the quantity of light you want to collect.

It is a necessity to make sure you collect the correct amount of light not underexposed but not overexposed levels. This is highly important due to the many different availabilities of width, time and quantity of light you wish to achieve.

For example,less amount go time in the light can work if you’re camera lens expands and is very wide.Alternatively for the same duration with a narrow lens can be used but you Will achieve less light.

EXPOSURE TRIANGLE: APERTURE, ISO & SHUTTER SPEED

exposure triangle

Each setting controls exposure differently:

Aperture: controls the area over which light can enter your camera
Shutter speed: controls the duration of the exposure
ISO speed: controls the sensitivity of your camera’s sensor to a given amount of light

although one section is able to use as many different combinations to achieve s certain style and technique. The key, however, is knowing which trade-offs to make, since each setting also influences other image properties.

ISO,aperture photo shoot

Leave a comment

For this shoot I wanted to experiment the same shot and how it works ind developing detail, colour,and background when changing the ISO and Aperture settings.these photos devoted from 100 to 1600 doubling every time.

The ISO speed determines how sensitive the camera is to incoming light. Similar to shutter speed, it also correlates 1:1 with how much the exposure increases or decreases. However, unlike aperture and shutter speed, a lower ISO speed is almost always desirable. As a result, ISO speed is usually only increased from its minimum value if the desired aperture and shutter speed aren’t otherwise obtainable.This can cage depending to lighting or if it happens to be a very quick shutter speed to capture an action shot. With the first few images you can see the development of a lower to higher ISO level. It slowly looses the detail and becomes too exposed and is unable too capture the image; as seen before.The ghee exposure is  available to ‘film grain” seen in traditional photography.

Secondly I focused on Aperture. Aperture is when A camera’s setting controls the area over which light can pass through your camera lens,uch like exposure and alliance of light. It is specified in terms of an f-stop values. In photographer slang, when someone says they are “stopping down” or “opening up” their lens, they are referring to increasing and decreasing the f-stop value, respectively. this is the widening snd retraction of the lens to determine the amount of access to light they wish to capture. This is the second half of the photos and the development detail and focus within the images.
