Technical Terms

Technical Terms

Technical Terms in photography and photo editing are many and sometimes difficult to learn. I have taken some of the terms and attempted to explain them on this page. More terms and definitions will be added as time goes on.

Some easy to understand explanations:

Photo Art

There are actually a couple of meanings here.

  1. It is the process of actually taking excellent photos by using some of the items defined below.
  2. Changing existing an ordinary photo and turning it into a beautiful oil painting with a look similar to a Monet, Van Gogh, Rembrandt and so on.
  3. The process of making a photo look like a watercolor, charcoal like, sketch and even an appealing piece of art for today’s younger generation (or older folks too).


Simply means the overall lightness of all aspects of an image.


This is the difference in two areas: Luminescence which is the difference between the light and dark areas of an image; Color this is the difference between two colors that are in contrast to each other. (Like Red and Cyan)

Depth of Field

Is just the difference from the closest to the farthest point from the camera – in the photograph.

Fill Light

Used to change the contrast (reduce) and lighten areas in shadow.


The lightest area of a photo that is not white.


Saturation refers to the dominance of hue in the color. You may also define it as the intensity of a hue or how vivid it appears.


The darkest area of a photo that is not completely black.

Out Of Bounds

(OOB) is a photo that has been manipulated so that they appear to be outside the boundaries of the original picture.

Digital Photo Editing

is changing or improving graphic images

Digital retouching

Is the Alteration of an artwork, computer graphics, or photograph for its enhancement, introduction of desired features, or reduction or elimination of the undesired ones.


High-dynamic-range imaging (HDRI) is a high dynamic range (HDR) technique used in imaging and photography to reproduce a greater dynamic range of luminosity than is possible with standard digital imaging or photographic techniques.

Interesting Update:
So I was doing some research the other day and found this very interesting information regarding Megapixel and Gigapixel cameras. Very interesting indeed. There is so much more detail when using the higher pixel count that it makes editing much easier.

DURHAM, N.C. — By synchronizing 98 tiny cameras in a single device, electrical engineers from Duke University and the University of Arizona have developed a prototype camera that can create images with unprecedented detail.

The camera’s resolution is five times better than 20/20 human vision over a 120 degree horizontal field.
