Defiance: Gravity, Belief and Reality

Defiance - Phil Richardson, Little Gaddesden
Phil Richardson
A composite image from May 2005 at St Peter & St Paul Church, Little Gaddesden.  The subject (me) photographed in a studio (Little Gaddesden village hall) using one softbox on white roll paper (Black would have been easier if i had a roll) and the background in low evening light at the church.

A green paper roll could be used as it is easy to chroma-key against, add black card for shadowing. In Photoshop afterwards apply dodging and burning, using levels to add colour and flatten for outside light.  Personally i prefer to use a desaturated layer to remove some colour.  

The figure has a slightly yellowish tinge and the background more green.  The background has had some selective dodging and flattening applied but little else.  You will need to need to trim the figure and darken the edges, to enhance the shadows further.

Create Snow in Photoshop using HDR

Using three building images as the basis of the image, one stop under for the highlights, the correct exposure for the mid-tones and one stop over for the shadows.  A fourth image of the sky from earlier in the afternoon and a little bit of spot colouring for corporate colours.  The snow was created using the selection tool, a layer mask and shaped brush over a graded white and grey background.

How to be Creative with White Balance

Learning how to use White Balance or colour balance on a camera is relatively straightforward. When it is sunny you can set the WB to 'Sunny', when indoors set to 'Tungsten' or 'Incandescent', cloudy conditions use 'Cloudy' and so on.  If you select a WB setting for different light conditions you can produce some creative results.  The custom WB setting will produce even more colours.

White Balance works by adjusting the colours in camera to neutralise the colour cast effects of the gas you are photographing in.  If you were to photograph a grey piece of card with the WB set to Daylight or Sunny, this is the light most of use see everyday, then the following would occur under specific light conditions. Photographing in daylight the card would be grey, tungsten it would be orange, fluorescent tubes produce a greeny-yellow colour, under cloud pale blue and in the shade a mid-blue.  To neutralise the colours you need to remove the colour cast and add the opposite colour in.  With the grey card just select the appropriate WB setting, if indoors with tungsten bulbs use Tungsten and the card will still be grey.

If you can learn what the opposite colours are and how they will react in different light conditions then you produce your own creative effects.  An easy way to learn how to change the colours is by learning their opposites with the primary colours of light and pigment.   With light we use RGB: Red, Green and Blue and pigment CMY: Cyan, Magenta and Yellow.  The opposite colours are as follows:


When you alter the WB settings with the same light conditions then you will alter the colour of the sky, a sunset, snow, water and even skin tone. You are able to make snow bluer by setting the WB to Tungsten, a sunset more orange by using a Cloud or a Shade white balance setting.  Below the WB settings with their natural colour and how they will alter the scene under daylight.

Using a sunset to demonstrate the effect of changing the WB settings on an image view the images below.  The camera used was a Canon 650D with a standard profile at ƒ4 on a 50mm lens.
