SWC ChroniclesMeeting # 10 November 22, 2013
Outline • News Updates • Due Dates and Schedule • Photography Workshop
News Updates • Our first issue has been published ! • Link of first issue on school website http://churchill.lakeheadschools.ca/wordpress/swcchronicles/
Improvements? • How did everyone like the format? • Spacing • Pictures • Lengths • Text & image sizes • What can we improve on?
Scheduling • Rough Copies will be due just before the end of November • We would like to get out the 2nd edition of SWC Chronicles out in early January
Photography Workshop
Photography Basics • What is a DSLR camera? • Digital single-lens reflex camera • Combines digital camera with a single lens reflex camera • Single-lens reflex camera uses a ‘mirror’ to allow the photographer to see exactly what will be captured • Contrary to a viewfinder
Important Features to Note • When you take a picture, you expose the sensor to light • How the light reaches the sensor is determined by the ‘focus’ • Two elements determine the amount of light that is let into the camera • These are called the “aperture” and the “shutter speed” • It is best to use a tripod if available
Focus and Zoom • Focus is deals with moving the image on the photo sensor to make it clear • To focus on a DSLR, simply turn the focus lens • You can also use the ‘auto’ feature • Zoom is how close or far something is
The Aperture • Aperture is the opening on the camera that changes in size to allow more or less light – similar to the pupil • Aperture is measured in “F-stop” or “F-number” and can be referred to as F15, F11, F8 etc. • The smaller the number, the less light that gets in
The shutter speed • The shutter speed is the amount of time the shutter is open for • Slower shutter speeds makes images bright and moving objects blur • Faster shutter speeds makes images darker and moving objects more sharp
Shutter speed and aperture In general, in similar lighting conditions, when you increase the aperture, you want to decrease the shutter speed and vice versa in order to get the optimal amount of light
ISO • ISO stands for “International Organization for Standardization” • Used by film speed ratings to determine the amount of light needed for a proper exposure • The ISO “speeds” range from 25 – 1600 • Lower ISO values means that it is less sensitive to light • Higher values means that it is more sensitive to light
ISO increases by increasing voltage in the photo sensor in the camera • This causes electrical charges in microscopic wells to spill into adjacent pixel wells • This results in the graininess which is also referred to as “digital noise” ISO 100 ISO 1600
Buttons ! Action mode Increases ISO and uses a fast shutter speed Portrait mode Increases aperture to blur background Landscape mode Decreases aperture to get a wide focus while focusing on the background Macro mode (‘close-up mode’) Decrease aperture to get a wide focus while focusing on things in the foreground
Manual Mode You control both the aperture and the shutter speed Aperture Mode You control the aperture and the camera auto picks the shutter speed Programmed Mode You control nothing. The camera auto picks both the aperture and shutter speed Shutter Mode You control the shutter speed and the camera auto picks the aperture
Example Situations • Track and Field – 100m sprint • Wider aperture, quick shutter speed and high ISO • Background of mountains • Small aperture and slower shutter speed, and lower ISO • Portrait • Wider aperture, medium shutter speed, lower ISO • Field of flowers in very bright day • Small aperture, medium-fast shutter speed, and lower ISO
The Rule of Thirds • The most aesthetically pleasing pictures have the subjects aligned with the 1/3 point on the picture • Pictures should be divided into 9 equal parts and the subjects should be on the intersections • Adds tension and ‘mystique’ • To avoid the picture to be cut in half
The Rule of Thirds • The rule of thirds should also be followed for a moving subject • However, the majority of the room should be placed in front of the subject
Important Terms to Remember • Aperture – the size of the opening in the camera • Shutter speed – the speed of the shutter • ISO – the sensitivity of the photo sensor in camera
Follow these tips • Always try to use the minimum ISO setting that allows for good lighting • Remember to get crystal clear focus • Use a tripod where you can • Decide if you want a wide focus or a narrow focus and change your aperture to suit • Use longer shutter speeds for blur effect and for rich contrasting pictures
