BSI Sensor

Share A BSI (Back Side Illuminated) Sensor is a fairly new technology that allows for a more efficient design of digital camera sensors.  In simple terms, the sensors work better in low light due to having wiring behind the sensor. This also helps with the transfer speed of data. Also […]


Crop Sensor

Share Crop Sensor is a term that refers to the smaller APS-C size sensors that are about 1/2 the size of a Full Frame sensor.  This is due the crop factor these cameras display when using a full frame lens and narrow the field of view. Facebook Twitter Google + […]


Wide Open

Share In photography, if you shoot “Wide Open” it means you are using the widest aperture possible (lowest f/stop number). This will let in the most light and give you the least depth of field.  If your lens adjusts from f/2.8 to f/16 and you shoot at f/2.8, then you […]


MLU

Share MLU is an acronym for “Mirror Lock Up”. This is a setting on some DSLRs which allows you press the shutter to first lock up the mirror and then take the photo with the next press of the shutter.  This is done to minimalize camera shake due to the […]


ASA

Share ASA is an acronym for “American Standards Association” and was the industry standard for rating a film’s ‘speed’ or sensitivity to light.  This was eventually taken over by ISO (International Organization for Standards) as a way to unite a few different systems (ASA, DIN, ISO, BSI). Many photographers who […]


Polarizing Filter

Share A Polarizing Filter (aka polarizer) is a filter which fits in front of your lens and blocks unpolarized light. Without getting into a physics discussion, you can say that a polarizing filter will cut unwanted reflections in your scene.  This filter can cut reflections and glare from windows, glass, […]


Program Mode

Share Most cameras have a Program Mode which will set the aperture, shutter speed and ISO based on how the camera meters the scene. Also known as ‘auto everything’, ‘auto mode’, ‘automatic’.  Most cameras will have this mode indicated by a “P” and likely coloured green. There is nothing wrong […]


Grain

Share Grain is another name for Noise.   This term is a holdover from the days of film, when a higher ISO film would have larger grains of silver to absorb more light.  The grain would then refer to decrease in image quality as the photo would look ‘grainy’. With Digital […]


F-Number

Share F-Number is another term for F-Stop. An F-Number is used to designate the size of the aperture (opening) in a lens. The larger the F-Stop number, the smaller the opening in the lens.  The F-Stop is usually shown as f/number (ex: f/8) – where the 8 is a number […]


Macro

Share Macro is a term used to describe a type of photography involving small subjects.  Generally true macro is defined when you have the subject at a 1:1 ratio on your film or sensor.  Macro photography can be achieved via special lenses, attachments or other settings. Facebook Twitter Google + […]


Remote Release

Share A remote release is an accessory which allow to trigger the shutter from a distance.  These generally operate via infrared, Bluetooth, Wi-fi or other wireless technology.  Many releases also allow you to control other settings like autofocus.  This would be different than a cable release which physically attaches to […]


Cable Release

Share A Cable Release is an attachment that connects to your camera which allows you to trigger the shutter with less vibration.  These are used anytime camera shake may be an issue.  Many cameras also work with a remote release which operates the camera via infrared, Bluetooth, Wi-fi or other […]


Field of View

Share Field of View is a specification used to describe how ‘wide’ a lens can view a scene.  A 28mm lens on a full frame camera will have about a 75° field of view, while a 200mm lens will have about 12°.  The shorter the focal length, the wider the […]


Angle of View

Share Angle of View is a specification used to describe how ‘wide’ a lens can view a scene.  A 28mm lens on a full frame camera will have about a 75° angle of view, while a 200mm lens will have about 12°.  The shorter the focal length, the wider the […]


Quiet Shutter

Share Quiet Shutter mode is an option in some professional cameras to lesson the amount of noise that the camera makes during exposure. Generally this applies to DSLRs which have to move a mirror out of the way during exposure.  In most cases, the mirror moves up, but doesn’t drop […]


Meter

Share A Meter is a device in your camera that helps you calculate the best exposure for the scene. Almost every digital camera will have a meter of some kind built into it.  Exposure / Light meters can be simple or very complex and provide options like spot metering. Meter […]
