Reflector

What Is A Reflector? When it comes to photographic lingo, a reflector actually refers to two distinct pieces of equipment.  Most of the time when people refer to using a reflector, they are talking about using a piece of reflective material to bounce light in a certain direction.  This piece of material usually contains a frame that keeps it taught enough to angle in a specific direction and therefore control the direction of the bounced light.  It has many uses because bouncing light gives it a much softer look.  That means we can bounce artificial light off a reflector...

Render

What Does Render Mean When Talking About Digital Photography? When talking about photography, specifically post-processing and image editing the term ‘render’ or the process of ‘rendering’  refers to the application of algorithms to a digital image file which convert the image information contained within the file into a viewable format on a viewing device. Rendering is also constantly occurring within digital cameras. In mirrorless cameras with an EVF or electronic view finder the information being received through the image sensor must be rendered in the EVF. Images are also rendered on the LCD screen when viewing them on a...

Resampling

 What Is Resampling and What Does It Mean in Photography? In photography, specifically post-processing and image editing ‘resampling’ is the process of altering an images resolution by either adding or removing extra pixels. Increasing the number of pixels in an image is often referred to as upsampling, reducing the number of pixels is referred to as downsampling. Resampling has two direct effects on an image file, firstly the resolution of the file will be altered depending on the number of pixels either added, or removed, and secondly the image file size will change. The actual process of resampling an...

Rim Light

What Is Rim Light and How Is It Used in Photography? In basic terms ‘rim light’ is a lighting technique where the image subject is backlit and the image is exposed to hide the subject features in shadow. The technique gets its name from the fact that lighting a subject in this way produces a thin line or ‘rim’ of light which appears to cling to the subjects outline. using rim light lifts the subject from the background in images rendered predominantly in shadow. In more complex situations, using extremely technical lighting setups rim light can be applied to...

Rule Of Thirds

What is the rule of thirds and how is it used in photography? The rule of thirds is a technique used to achieving a pleasing composition within a photograph or graphic design. Application of the rule involves dividing a scene into three columns both horizontally and vertically, and then composing an image by placing the subject at a point where the lines dividing the columns intersect. An off-centre composition appears more pleasing to the human eye and the rule of thirds is a simple method of achieving such a composition. Most digital cameras feature guide lines which can be...
