Colour spaces explained

To ensure the right colours in your images, it helps to understand how colour spaces work… Colour spaces are mathematical models describing the way colours can be represented. The easiest way of visualising them is to think of a box containing all the possible colours that can be produced by mixing the three primary colours of light: red, green and blue.

How to choose an image editor

Although the basic image editor in a computer’s operating system may be adequate for snapshooters, serious photographers require a dedicated editing program. Adobe’s Photoshop is often the first program people think of, however there are lower cost and free alternatives for both photo editing software and workflow applications.

Equipment for editing your photos

In this article we will look at the basic and some of the more advanced hardware equipment you need for editing and printing digital images, focusing on still pictures (not movie clips, which have different requirements). The tools you need will vary depending on what you want to do with your photos.

When to use filters

Back in the days of film, most photographers fitted UV, haze or skylight filters to every lens, partly to block the ultraviolet radiation that could impart a blue cast to photographs (all films can record invisible UV radiation) and partly to protect the front element of the lens. Filters still have their uses for today’s digital photographers, however there are situations where you need to be discriminating in your choice of filter.

Special effects photography at night

Almost since the first point-and-shoot digicams were invented, camera manufacturers have come to the aid of novice photographers by providing pre-set exposure modes to help them select appropriate aperture, shutter speed and ISO settings for popular photographic genres. The first of the ‘Scene’ pre-sets were for portrait, landscape and sports photography. But it wasn’t long before night portrait and night landscape pre-sets were added and it’s not uncommon for modern cameras to provide separate pre-sets covering fireworks, candlelight, sunset and dusk and/or dawn.

Creative editing

This article is created to show you some of the ways in which images can be manipulated to add a sense of movement to a subject that is essentially static. Most software applications provide a range of tools, some of which are easier to use than others.
