Managing colour

The idea here is to correct significant colour casts in a number of JPEG images. It proved a very useful exercise.

P561:  F8 @ 1/40  ISO 100  22mm  WB Tungsten  - Original image

P561 was a classic example of not checking the white balance setting before taking an image. The tungsten setting resulted in a very blue cast on a very bright cloudy day.

P561a is the result of using the equivalent of a 'grey dropper' placed on the asphalt.It brings the colour back to nearer the actual colour on the day which I further enhanced by adjusting the colour saturation to bring out the colour of the costumes.

P562: F5.8 @ 1/8 ISO 1600  98mm AWB

The original image of our cat ( P562 ) was disappointing as it came out with a yellow cast that did not reflect the true markings of her fur.

Placing the 'grey dropper' on the dark grey of one of the stripes produces a more accurate image.Try as I might I could not adjust the image further to remove the slight pink tinge on the chin.

P563: f3.5 @ 1/3  ISO 400 18mm

P563 is one of a number of pictures taken to illustrate a meeting made all the more difficult to take because of the changing light in the pub room which ranged from darkening natural light through to an alarming red light effect coming from wall lights as the evening progressed. This image was taken half way through the light changes and came out with a strong yellow / orange cast.

With this image I focused on the patch of charcoal grey top right  of the picture again with the 'grey dropper' which produced an whiter image more easy to reproduce for a local leaflet.
