Adjustment Layer

What Is an Adjustment Layer and How Is It Used in Image Editing? This is a layer containing an image adjustment or effect instead of image content. Like a red Cellophane overlay on a print, an adjustment layer will alter the appearance of layers below it, but not actually alter their content, making adjustment layers a cornerstone of reversible, ‘non-destructive’ editing. The adjustment can be altered, hidden or removed at any point. Adjustment layers allow photographers to experiment with edits to their photographs without risking permanently changing the original image content. Adjustment layers can also be copied and applied...

Color Palette

What is a Color Palette When Talking About Photography and Image Editing? Also referred to as ‘palette’ the term ‘color palette’ describes the entire range of colors that can be rendered by a digital device such as a camera LCD or a computer monitor, or the range of colors contained within a specific image. A computer monitor may have a color palette of 16 million colors, an image on the other hand often contains a much smaller number, often 256. The term is also used to describe a collection of colors, usually displayed graphically in RGB triplets, which a...

Cropping

What Does Cropping Mean Cropping is the process of trimming the edges of a photo, either digitally with photo processing software, of physically when a print is trimmed with a knife or guillotine.  Ideally, cropping should be used as a tool to improve upon the composition of the original photo, though sometimes it is necessary in order to make an image fit a specific dimension of photographic frame. The crop tool is one of the most important and widely used tools in any image processing software, whether it is in a mobile app, or a full-blown piece of computer...

Digital Asset Management

What Is Digital Asset Management? The term “Digital Asset Management” is a bit of a mouthful so most people refer to it by the acronym, DAM.  Please see the DAM entry in the photography glossary to get more information on what this is and why it’s important to photographers.   Additional Reading What Is Photo Mechanic?

Image Browser

What is an Image Browser and how is it used in photography? An Image browser is a piece of software specifically designed to allow viewing of digital image files. Modern digital photographers often have catalogues of tens of thousands of digital photographs, an image browser can be used to quickly visually search, organize and delete image files. Image browsers allow images to be organized on the fly using information stored in the image file’s metadata. This allows a photographer to find specific images or types of images extremely quickly, a much better solution that looking through thousands of images...

Image Editor

What Is an Image Editor and How Is It Used When Taking Photographs? When talking about photography, an image editor is a piece of computer software which is used to edit a digital image file. Modern editing software, for example Adobe Photoshop, is extremely powerful allowing the quick application of complex editing techniques such as color mapping, masking and retouching in a non destructive environment; changes made to the original digital image file can be undone allowing a photographer to experiment with various techniques to produce a desired image. The pattern of changes made to an image can also be...

Interpolate

What Does Interpolate Mean What Talking About Processing Photographs? When talking about photography, specifically image editing and post-processing, the term ‘interpolate’ refers to the process of enlarging an image beyond the resolution at which it was captured. Unlike simply enlarging the pixels within an image, interpolating an image involves applying an algorithm which adds new pixels to the image, therefore increasing it’s overall resolution. Interpolation also occurs when applying various kinds of digital adjustment to an image for example rotating an image at anything other than 90 degree intervals, or applying correction for barrel distortion. In both these examples...

KB

What Does KB Mean When Talking About Photography? The acronym ‘KB’ refers to one ‘kilobyte’, a unit of measurement used to describe the size of a digital file. One kilobyte is comprised of 1,024 bytes of digital information. When a picture is captured on a digital camera the resulting file must be stored on the cameras memory; Depending of the resolution of the captured image, and the file format used to encode it, an image will take up a certain number of kilobytes on the cameras memory. Dividing the total size of a camera’s memory in kilobytes by the size...

Lossless

What Does Lossless Mean When Talking About Image Editing? The term ‘lossless’ refers to a form of non-destructive compression which can be applied to a digital file so that it takes up less space than it would in its original format. This allows for more images to be stored on a storage medium. The advantage of lossless compression, and where it gets it’s name from, is that no data is lost during compression. This is particularly important when storing digital photographs as they contain a lot of data which is required to render them correctly.  One example of a...
