Digital cameras have ‘white balance’ built in to them to deal with different colour temperatures so the brightest parts of an image are recorded in pure white, without a colour tinge.
Conventionally, sunrise and sunset views are left alone and uncorrected by white balance because most people find them attractive, while blue shade does tend to look wrong to most people.
The exercise asks for more-or-less a repeat of the shots for part on of the exercise – shooting each with different white balance settings – a first set to daylight, a second to shade and a third to auto. As I shot the originals in RAW I’ve chosen to apply the different white balance options in Lightroom to them, rather than reshoot.
The first on “daylight’ and the third on “auto” appear closest to white. The middle, on “shade” is very yellow – and overly so to my eyes, so isn’t as pleasing an image.
Again the first and third are closest to white, though there is a very subtle yellow tint to the third. There is a stronger yellow tint to the middle image with white balance set to “shade”, but not as pronounced as with ‘midday sun’, and it’s the shot I prefer due to this hint of warmth.
This time the third image is closest to natural light – with whites being white – and quite distinctly so. The middle image is overly-orange. The first set to “daylight” is still orange, but I find it a more pleasing image as it has a warmth to it that is clearly close to ‘sunset’ which the third image has completely lost.
