The document discusses the three pillars of photography - shutter speed, aperture, and ISO - and how they work together to control the exposure of images. Shutter speed determines how long the sensor is exposed to light, with longer speeds creating brighter, more blurred images. Aperture refers to the size of the opening through which light passes, with larger apertures admitting more light for brighter images but less depth of field. ISO represents the camera's light sensitivity, with higher ISO numbers allowing lower light sensitivity but risking more image noise. All three elements must be balanced to achieve proper exposure.

AdvancedExposure1
The document provides an overview of the key concepts of exposure including aperture, shutter speed, and ISO. It explains that aperture controls depth of field and is measured in f-stops, shutter speed determines how long light is allowed to enter the camera and is measured in fractions of a second, and ISO controls the camera's light sensitivity. It also notes that aperture, shutter speed and ISO work together to determine exposure and that changing two of the settings while keeping exposure the same is called equivalent exposure. Learners are encouraged to practice adjusting the settings in manual mode and bring in photos for discussion.
Photography
Photography is an art form that involves focusing light through a camera lens onto a sensor or film. Key aspects of photography include exposure, comprised of aperture, shutter speed, and ISO. Different genres of photography include landscapes, portraits, and street photography. Composition techniques like the rule of thirds can make photos more interesting. Post-processing in programs like Photoshop and Lightroom allow adjusting colors, exposure, and other aspects of photos.
Composition
The document discusses composition in photography. It notes that a good composition tells a story and catches a reader's attention within a few seconds using more than one element. It provides tips on critiquing visuals in daily media and asking what constitutes a journalistic image. Key terms are also defined, such as shutter speed, aperture, exposure, SLR, focus, and noise. Rules of composition discussed include the rule of thirds, framing, balance, and featuring people. The document emphasizes that people are more interesting subjects than static shots and to identify people if there are five or fewer in an image.
Photography 101
Shutter speed controls how long the camera's shutter remains open, with lower speeds admitting more light and possibly causing motion blur, and higher speeds admitting less light and slowing motion. Aperture, like the pupil in a human eye, controls the size of the camera lens opening to restrict or admit light using f-stops, with lower numbers giving shallower depth of field and higher numbers greater depth of field. ISO controls the camera sensor's sensitivity to light, with lower numbers making the sensor less sensitive and images having less grain in bright light, and higher numbers making the sensor more sensitive for low-light shooting but resulting in more image noise.
Camera Terminology
This document provides an overview of common photographic terminology used in digital photography. It defines key terms like shutter speed, ISO, aperture, depth of field, manual and automatic exposure, color balance, and white balance. Shutter speed refers to how long the camera sensor is exposed to light when taking a photo. ISO measures the camera sensor's light sensitivity, with higher numbers used in darker situations. Aperture controls depth of field by adjusting how much of the photo is in or out of focus. The document also explains manual and automatic exposure modes.

Camera in manual settings
The document discusses key manual camera settings - aperture, shutter speed, and ISO. It explains that a larger aperture allows more light in but results in a shallower depth of field, while a smaller aperture allows less light in but increases depth of field. Shutter speed determines the length of time the camera's shutter is open, affecting exposure, and ISO controls the camera's light sensitivity, with higher ISO numbers increasing sensitivity but also noise.
Shutter Speed
The shutter is a door inside the camera that opens when the shutter button is pressed, allowing light to enter and expose the image sensor. At slow shutter speeds moving objects appear blurry, while at fast shutter speeds they appear clearer. Shutter speed is measured in fractions of a second, with higher numbers indicating faster speeds. Faster shutter speeds require more light and can freeze motion, while slower speeds allow blurring effects. The document provides guidance on selecting shutter speeds for different types of shots and adjusting aperture, ISO, exposure compensation if images appear too dark at a desired shutter speed.

film-How to Make an Exposure
To make an exposure, you set the ISO, aperture, and shutter speed. The aperture controls how much light enters through the lens. A higher f-stop number means a smaller aperture opening. Shutter speed controls how long the sensor is exposed to light, from fractions of a second to minutes. Faster shutter speeds freeze motion while slower ones blur it. ISO controls the film's light sensitivity, with higher numbers allowing faster shutter speeds in low light. Using the light meter, you adjust the aperture and shutter speed until the meter indicates the correct exposure.
Good Exposure
The document discusses proper film exposure and how to achieve it through adjusting aperture, shutter speed, and film speed settings. It explains that proper exposure is achieved when shadow detail is visible, and that underexposure and overexposure result in negatives that lack contrast or definition. Combining a fast aperture with a quick shutter speed, or a small aperture with a slow shutter speed, can produce equivalent exposures. A light meter should be used to guide setting the aperture and shutter speed based on the film speed.
Week 2
This document provides information about how photography works and how cameras capture images. It discusses how cameras use lenses, apertures, and sensors to record light reflecting off objects. When light hits the image sensor, it is converted into electronic signals and pixels, forming a digital image. The document also describes different focusing systems and modes that give photographers control over which part of the scene is in sharp focus. It provides examples of how photographers can select specific focusing points or have the camera decide to keep moving subjects in focus.
Manual camera settings1
Aperture determines the amount of light that reaches the camera sensor, with smaller apertures resulting in larger depth of field but slower shutter speeds. Shutter speed determines how long the camera's shutter is open, with longer shutter speeds allowing more movement to be captured but shorter shutter speeds providing more clarity. ISO measures the light sensitivity of the image sensor, with higher ISO numbers producing grainier images but being more sensitive to light.
Manual camera settings
Aperture determines the amount of light that reaches the camera sensor, with smaller aperture stops having larger depth of field but slower shutter speeds. Shutter speed controls how long the camera shutter is open, with faster speeds freezing motion but less clarity, and slower speeds capturing movement but more definition. ISO measures the light sensitivity of the image sensor, with higher ISO numbers having more grain but being more sensitive in low light conditions.
film-Shutter Speed and Motion
Shutter speed controls the duration that light is allowed to hit the camera's sensor or film. Faster shutter speeds freeze motion while slower speeds allow for blur. When photographing moving subjects, choose shutter speed first then set aperture for proper exposure. Slower shutter speeds are useful for panning shots, zooming during exposure, light painting, and night photography but require a tripod to avoid camera shake. Flash can also be used with slower speeds to freeze some motion while blurring ambient light during the remainder of the exposure.
Photography basics
This document provides an introduction to photography basics, including how cameras work and the key components that control light exposure. It explains that light travels through the lens and aperture to the sensor, where it is transformed into pixels. The aperture controls the amount of light that reaches the sensor, while the shutter speed determines how long the sensor is exposed. Together with ISO, aperture and shutter speed determine the overall exposure of a photo. The document also outlines common scales and terminology for aperture, shutter speed and ISO settings.
The parts of a digital camera

Manual and automatic exposure options are described along with other important topics like color balance, white balance, composition techniques, and macro photography.
Photo 1 Quiz 1
This document provides definitions and basic photographic concepts:
1. Lenses are categorized as prime lenses with a fixed focal length or zoom lenses with a variable focal length. A normal lens on a 35mm camera has a focal length of 50mm. Wide-angle lenses have shorter focal lengths and telephoto lenses have longer focal lengths.
2. Film has a light-sensitive layer called the emulsion. ISO rates the film's sensitivity to light - higher ISO means faster/more sensitive film.
3. The shutter controls the duration of exposure, affecting the recording of movement. Aperture controls the amount of light through adjustable openings called f-stops, also impacting depth of field.
Exposure; A Love Triangle
This document summarizes the key elements of exposure in photography - aperture, shutter speed, and ISO. It explains that exposure is determined by these three settings and available light. Underexposure and overexposure occur when shadows or highlights are unreadable, respectively. Each setting impacts depth of field, motion blur, and image noise. The most important thing is to experiment with these settings in practice to understand exposure.
Night photography with notes
Night photography techniques are discussed for different lighting conditions. For long exposures with existing light, the document recommends setting ISO to 800, aperture priority mode, wide aperture, manual focus, and using a timer to open the shutter for multiple seconds. For shots with no light, it suggests overexposing film by 5-6 stops. Painting with light involves setting the camera to manual mode, a 30 second shutter, wide aperture, manual focus, using a timer and flash to illuminate the scene within the 30 seconds.
How to Expose
The document discusses the basics of exposure in photography, including white balance, aperture, shutter speed, ISO, and using the light meter.

The document discusses the concept of the "gaze" and how it relates to objectification, especially of women. It defines the gaze as a mode of viewing that reflects a gendered code of desire, implying a power dynamic between the gazer and the object of the gaze. The gaze has been used to study how women are objectified as objects to be looked at in visual texts. This objectification through the gaze can lead women to internalize being viewed as objects for male pleasure and desire. Psychoanalytic film theory explores how films reflect and reinforce the patriarchal view of women as the "Other".

Exposure
The document discusses the three elements that control exposure in photography - shutter speed, aperture, and ISO. Shutter speed determines how long the shutter is open to allow light into the camera, with faster speeds letting in less light. Aperture refers to the size of the opening in the lens, with larger apertures admitting more light. ISO represents the camera's light sensitivity, with higher ISO numbers allowing for proper exposure in lower light. Together these elements provide photographers control over the amount of light captured in an image.
Basics Of Photography.
Photography involves capturing light with a camera. There are three main factors that determine the exposure of a photo: shutter speed, ISO speed, and aperture diameter. Shutter speed controls how long the camera's shutter is open to let in light. ISO speed determines how sensitive the camera's sensor is to light. Aperture diameter refers to the size of the opening in the lens, with a lower f-number meaning a wider aperture that lets in more light. These three factors work together and are measured using "stops" to produce a properly exposed photo. Mastering these fundamentals of light and exposure is key to learning photography.

It then provides detailed explanations of each of the three elements - aperture, shutter speed, and ISO - and how they work together to determine proper exposure in a photograph. It also briefly discusses restoration of old photographs and uses of Adobe Photoshop. Finally, it lists and provides examples of several famous local photographers and one of their notable photographs.
Camera and its functions
This document discusses the key features and functions of a camera. It begins by defining a camera as an optical instrument used to take photographs or make films. It then explains the primary features that control a camera's functionality - focus, aperture, shutter speed, and ISO. Focus controls the sharpness of the image by adjusting the lens. Aperture regulates the size of the lens opening to control the amount of incoming light. Shutter speed determines how long the camera's shutter remains open during an exposure. And ISO specifies the light sensitivity of the image sensor, with higher ISO resulting in lower image quality.
Understanding Exposure Triangle in Photography
The exposure triangle is a common way of associating the three variables that determine the exposure of a photograph: Aperture, Shutter speed, and ISO. One must balance all three of these to achieve a desired result, an adjustment of one requiring adjustments of at least one of the others. They do not only affect exposure, but are also the largest determiners of the global appearance of an image; thus, their mastery is absolutely crucial both for technique and composition.
Objective:
1. To learn how to use the exposure triangle to set a correct exposure in your camera.
2. To learn about the link between ISO, shutter speed and aperture.
3. To learn what aperture is, and how to use it creatively.
4. To learn what shutter speed is, and how to produce blur or freeze motion photos.
5. To learn what ISO is, and how to prevent 'noisy' photos.
Target Audience: Photography Enthusiasts
Agenda:
• To understand Correct Photograhy Exposure.
• To understand the components of Exposure Triangle.

Expected Outcomes:
By the end of the ppt/pdf, the participants will be able to:
1) Better understanding of each of the three exposure settings, how they are measured, what they do, and how they interact.
2) Better equipped to manipulate the exposure of your images, as well as the artistic presentation of motion, depth of field, and digital noise.
3) Better control of the manual mode in camera.
Going Manual
This document provides information on switching from automatic to manual modes on a camera. It describes the characteristics and uses of different exposure modes including Program, Shutter Priority, Aperture Priority, and Manual. It also covers different scene modes like Portrait, Landscape, Macro, Sports, and Night Portrait. The exposure triangle of aperture, shutter speed, and ISO is explained. Concepts of over and underexposure, depth of field, freezing versus blurring motion, and the relationship between ISO and image quality are discussed. Activities are suggested to understand these photographic concepts hands-on.
A Level Photography - The Basics
An A Level Photography PowerPoint on the basics including camera functions, elements of photography and the three pillars.
Photographic terminology (1)
Shutter speed refers to the length of time a camera's shutter is open, exposing the sensor to light. A faster shutter speed can freeze motion while a slower shutter speed can create motion blur. ISO measures the light sensitivity of the sensor, with lower numbers indicating less sensitivity and finer grain. Aperture controls the amount of light entering through the lens and determines depth of field, the zone of sharp focus. Manual exposure requires adjusting shutter speed, aperture, and ISO together, while automatic exposure lets the camera set these automatically.
Aperture, Shutter Speed and Depth of Field
The document introduces aperture, depth of field, and shutter speed as they relate to photography. It explains that aperture is the size of the lens opening and controls the amount of light entering the camera. A larger aperture admits more light and results in a shallower depth of field where only the subject is in focus. A smaller aperture admits less light and produces a larger depth of field where the subject and surrounding areas are in focus. Shutter speed determines how long the camera sensor is exposed to light and must be adjusted based on lighting conditions to avoid under or overexposure. Aperture, depth of field, and shutter speed all interact to control the exposure of the photo.
Exposure triangle
The exposure triangle represents the three variables that determine a photo's exposure: aperture, shutter speed, and ISO. Aperture refers to the opening of the lens and affects depth of field. Shutter speed determines the length of time light hits the sensor and is used to freeze or blur motion. ISO enhances exposure but reduces image quality as it increases. Understanding the relationship between these three elements is key to properly exposing photographs in different lighting conditions.

ISO measures a camera's sensitivity to light, with higher ISO numbers allowing photos in low-light. Aperture is the opening that controls how much light hits the sensor, with larger apertures allowing more light and shallower depth of field. Shutter speed controls exposure and can convey motion, with faster speeds freezing action and slower speeds blurring it. The task is to take six photos in pairs illustrating the effects of different ISO, aperture, and shutter speed settings.

ISO measures a camera's sensor sensitivity to light, with higher ISO numbers allowing low-light photography. Aperture is the opening that controls the amount of light reaching the sensor, with larger apertures admitting more light and achieving shallower depth of field. Shutter speed controls exposure and can convey motion effects; faster shutter speeds freeze action while slower shutter speeds blur motion. The task is to take six photos in pairs illustrating the effects of different ISO, aperture, and shutter speed settings and present them side by side.
Understanding Exposure
The document discusses the basics of photography, specifically exposure. It explains that the three components that control exposure are aperture, shutter speed, and ISO. Aperture controls the amount of light entering the camera by adjusting the size of the opening. Shutter speed determines how long the light is allowed to fall on the sensor, and is used for fast moving subjects or low light. ISO makes the sensor more or less sensitive to light and is increased in low light, but results in grainier images at higher levels. Together, these three elements must be balanced to achieve proper exposure in a photo.
Taking pictures
The document provides information on key rules and concepts for taking pictures, including how to properly expose film by setting the camera's aperture and shutter speed based on the film's ISO rating and lighting conditions. It describes the "expose rule" for determining exposure time and effects, the "compose rule" for arranging elements in the frame, and the "rule of thirds" for composition. It also covers focus modes, exposure modes, light metering, and the relationship between aperture, shutter speed, film speed, and achieving the proper exposure to avoid under or overexposed photos.

Lesson 4 camera settings
This document discusses key digital photography concepts such as exposure, aperture, shutter speed, white balance, and ISO. Exposure is determined by aperture and shutter speed, with aperture controlling how much light enters the lens and shutter speed setting the duration of light exposure. Other settings like white balance remove color casts to accurately render white tones, while ISO impacts the shutter speed and aperture combinations available by adjusting the camera's light sensitivity.

Photography basics
- 1. Photography Basics Shutter speed, Aperture and ISO
- 2. Three pillars of photography • Shutter speed • Aperture • ISO Balance of all three
- 3. Shutter speed The shutter blocks all light from exposing the image sensor (or film) until you press the button. Then it quickly opens and closes, exposing the image sensor with a flash of light. You can control the length of time the shutter remains open by setting the shutter speed. • Longer the shutter speed = more light (brighter image) and more motion blur. • Smaller the shutter speed = less light (darker image) less motion blur
- 6. Aperture Before the light reaches the image sensor it passes through an opening called an aperture. The Aperture is like a pupil. You control the aperture by adjust the opening also called the f-stop • Smaller F-stop number = larger opening for more light (brighter image) and shallower depth of field • Larger F-stop number = smaller opening for less light (darker image) and greater depth of field.
- 7. Aperture
- 9. ISO ISO is the level of sensitivity that your camera (image sensor) to available light. The lower the number the less sensitive to light it will be. Always try to stick with your cameras base ISO level for better quality images.
