Judging colour temperature Part I

Flickr Tags:
This exercise is to use a subject that can moved around and shots taken throughout the day but using a white balance of daylight and not using an automatic setting in order to compare how light colour changes in different conditions

All photographs were taken using Aperture priority with the largest aperture f1.8 on a 50mm prime lens using centre weighted average metering for the exposure The white balance was set to daylight (colour temperature of 5250K). The photo’s were shot in raw but then converted directly into JPEG from the camera with no editing.

Midday Sunshine – Daylight Setting
50mm f/1.8 1/3000 sec ISO 100

With the sun high in the sky and the daylight setting produced a neutral light colour to the photograph. The light was also quite hard, and more contrast from the direct sunlight which impacted the highlights, with some completely blown. Also note the speed of the shutter had to be to compensate the strong light with the large aperture to get exposure (..and it’s still not exposed correctly)

Midday Shade – Daylight Setting
50mm f/1.8 1/750 sec ISO 100

This was taken within a few moments of the first shot, but taken in a shaded area. The light colour appears slightly warmer than the first, the shade has also diffused the light giving it a much softer feel suiting the subject better. I feel that the light makes the image a bit flat; although this is helped a bit by the depth of field

Evening Sunset – Daylight Setting
50mm f/1.8 1/750 sec ISO 100

The evening sunset produced the most dramatic change in colour, compared against the neutral midday, with the orange glow of the low sun adding a much stronger colour and warmth to the photograph.
