Exposure is a critical element in photography. Until recently it was common practice for landscape photographers to slightly underexpose image to increase highlight detail and increase saturation. But there is a new school of thought which suggests over exposing just short of blowing out the highlights will actually give you a better range of colours.

HDR 1 – taking the exposures

HDR means High Dynamic Range photography. It refers to a method of capturing a larger range of light detail than is possible with a single exposure. This article will look at the technique of multiple exposure capture with a DSLR.

Layers and Masks 2 – Adjustment Layers

Like layers, curve adjustments is a way of adjusting the brightness/ darkness levels in an image. The emphasis is put more on contrast and adjusting curves is a very smooth and sophisticated way of adjusting contrast.

Basic Adjustments – Levels

When you adjust levels, you are adjusting the range of the brightness/ darkness levels in an image.  This is determined through a histogram. The histogram displays the distribution of the different light value in an image. For example, a dark image would have a lot of value at the dark end of the spectrum (left hand side of the histogram), a bright image would have a lot of values at the bright end (right hand side).
