Aperture
The document discusses various aspects of digital photography including exposure controls like aperture, shutter speed, and ISO and how they impact photographs. It explains different camera modes like portrait, landscape, and macro mode and how they set the appropriate exposure settings for different types of subjects. The document also explores concepts like depth of field and includes exercises to demonstrate how changing the aperture can impact the area of the photograph that is in focus.
Basics of photography
The document provides an overview of key photography concepts including exposure, aperture, shutter speed, ISO, depth of field, focal length, and lens types. Exposure is determined by the amount of light reaching the image sensor, and can be controlled through aperture size and shutter speed settings. Aperture refers to the diameter of the lens opening while shutter speed is the duration that the camera's shutter is open. These settings, along with ISO, must be balanced to achieve proper exposure. Depth of field relates to the distance over which objects appear acceptably sharp, and lenses can be either prime lenses with a fixed focal length or zoom lenses with a variable focal length.
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.
Digital Photography- Exposure Triangle
This document discusses the exposure triangle concept in digital photography, which involves the relationship between aperture, shutter speed, and ISO. It explains that aperture controls the size of the lens opening, shutter speed determines exposure time, and ISO measures the camera sensor's light sensitivity. The three elements are interrelated - changing one requires adjustment of another for proper exposure. Examples are provided of settings suitable for different lighting conditions to avoid over- or underexposure. Mastering the exposure triangle is essential for creative control over photographs.

Photography 101
The document provides an overview of digital photography, including definitions, types of cameras, camera parts and features, characteristics of light, and basic concepts like exposure, histograms, metering modes, and composition rules. It covers topics such as the sensor and lens of a digital SLR camera, how light is captured, and factors to consider when setting up a shot like ISO, white balance, and the exposure triangle of aperture, shutter speed and ISO.
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.
Aperture, exposure and depth of field
This document discusses aperture, exposure, and depth of field in photography. It explains that aperture controls the amount of light entering the camera, with smaller f-numbers indicating larger apertures that allow more light. Larger apertures result in shallower depth of field, while smaller apertures provide deeper depth of field. Shutter speed controls the duration of exposure, with faster speeds freezing motion and slower speeds blurring it. Aperture and shutter speed can be adjusted to achieve proper exposure.
Photo shutter speed
The three pillars of photography are aperture, shutter speed, and ISO. Shutter speed refers to the length of time the camera sensor is exposed to light, ranging from very fast speeds like 1/2000 of a second to slower speeds like 1 seconds. A fast shutter speed can freeze motion while a slow shutter speed allows motion blur. The combination of shutter speed and aperture also impact depth of field, with a large aperture and fast shutter speed producing a shallow depth of field.

This study mapped the geomorphology of the southern Margaritifer Terra region of Mars to understand how water may have shaped its surface over time. The goals were to create a detailed geomorphic map of previously unmapped craters and alluvial fans through image analysis and determine the relative ages of features. The method involved using existing maps and imagery in JMARS software to analyze the area and create a new geomorphic map. The results suggest localized rainfall or snowmelt formed small valleys and gullies through fluvial processes related to precipitation and surface flows. A crater may have once contained a lake. Understanding the water history helps assess the potential for past habitability.

Depth of field
This document discusses depth of field and shutter speeds in photography. It defines depth of field as the area of an image that appears acceptably sharp, and explains that the three factors controlling depth of field are distance from the lens, f-stop, and focal length. Shorter focal lengths and smaller f-stops result in greater depth of field, while closer subject distance leads to shallower depth of field. Shutter speed controls the amount of time light can enter the lens, with faster speeds freezing motion and slower speeds allowing blur. Camera and subject movement can both cause unsharp images, so shutter speed must be set appropriately based on lighting and motion.

Week 3 Lens And Focal Lenghts
Here are two photos demonstrating different angles of view from changing focal length:
[PHOTO 1]
This photo was taken with a wide-angle lens around 18mm. It captures a large field of view and makes objects appear smaller.
[PHOTO 2]
This photo of the same scene was taken with a telephoto lens around 70mm. It has a narrower field of view and makes objects appear larger.
The perspective does not change between the two photos, only the angle of view changes based on the different focal lengths used. Changing focal length adjusts how much of a scene is captured rather than the perspective or point of view.
DIGITAL CAMERA SHUTTER SPEED
In photography and digital photography the shutter speed is the unit of measurement which determines how long shutter remains open as the picture is taken. The slower the shutter speed, the longer the exposure time. The shutter speed and aperture together control the total amount of light reaching the sensor. Shutter speeds are expressed in seconds or fractions of a second. For example 2, 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, 1/2000, 1/4000, 1/8000. Each speed increment halves the amount of light.

Camera parts-and-function
Camera parts include the lens, aperture, and shutter. The lens focuses light, the aperture controls the amount of light, and the shutter controls the exposure time. Exposure is determined by the intensity of light and duration of exposure. Megapixels refer to image resolution, while ISO relates to the camera's light sensitivity. Aperture affects depth of field and shutter speed controls motion blur. Modes include automatic, scene-specific, manual, and drive modes like burst which influence how photos are taken. Flash modes control the use of onboard flash.
clinical photography basic approach
Photography is used in dentistry for patient education, treatment planning, diagnosis, teaching, research, and communication. Key terms related to cameras include resolution, pixel, focal length, ISO speed, shutter speed, and aperture. Extra-oral photographs are important for documenting the face and include frontal smiling and relaxed views and profile views. Standardizing camera positioning, lighting, background, and patient positioning is important for documentation.
Photography in Orthodontics

Basics of dslr photgraphy
This document provides an overview of the basics of DSLR photography. It explains that a DSLR uses a mirror inside the camera body to reflect light from the lens up into an optical viewfinder. It discusses the key elements of shutter speed, ISO, and aperture. Shutter speed determines how long the camera shutter is open, ISO controls the brightness of photos, and aperture refers to the size of the lens opening which impacts depth of field and light intake. Examples are given of how different shutter speeds, ISO levels, and aperture sizes affect photographs.
Types of Camera (Old school VS New School

The document explains automatic, semi-automatic, and manual modes as well as other settings like drive modes, flash modes, and optical versus digital zoom lenses.
Photography
The document provides information about photography in orthodontics, including:
1) Photographs are an essential part of clinical documentation in orthodontics, with full sets taken at the beginning and end of treatment, and some mid-treatment.
2) Digital photography has replaced film and allows immediate viewing, editing, and sharing of images.
3) Professional digital SLR cameras provide the best image quality for orthodontic photography when used with macro lenses and appropriate exposure settings.
4) Photography requires specialized equipment like retractor mirrors, and adequate lighting and background to capture diagnostic quality intraoral and extraoral images.
Understanding exposure
Exposure is controlled by aperture and shutter speed to regulate the amount of light entering the camera. Too little light results in a dark image while too much light makes the image appear washed out. Aperture refers to the opening of the lens and is measured in f-stops, with higher numbers indicating a smaller opening. Shutter speed controls the duration that the sensor is exposed to light. Proper exposure settings help avoid issues like camera shake from slow shutter speeds.

Funtion OF camera.ppt
This document discusses camera functions and exposure settings. It explains that exposure is determined by the intensity of light, controlled by aperture, and the duration of light, controlled by shutter speed. Shooting modes include automatic, portrait, landscape and more. ISO refers to the film's sensitivity - higher ISO is more sensitive. Aperture and shutter speed settings are described in full-stop increments, where each full stop doubles or halves the light. The document also covers metering light and drive modes like single shot and continuous.
Basic photography & intro to dslrs

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
