Orange
A warm and festive colour (apparently – I didn’t see much at Christmas though). It has some of the energy of red, and the optimism and pleasure of yellow.
The photograph of the graffiti was taken on my mobile phone, so I can’t really compare the exposure with the other photos. But I increased the saturation, colour temperature and contrast later in post processing.
For the gas pipeline sign, I applied +1/3EV when taking the image, then in post processing I changed the white balance to sunny and added some contrast using the curves control.
Green
The human eye will detect more varieties of green than any other colour. It’s strongly associated with nature, particularly springtime, but it also has connotations of hope or envy.
I wanted to create an image that had a variety of greens, so I looked towards nature. There was no exposure compensation, just a tiny increase in saturation, vibrancy and hue.
The circuit board was quite heavily altered in post processing to make it look less natural. Exposure was increased by +0.75EV (it was backlit and I wanted it to appear slightly lighter than it was naturally). I added a cross processing effect and increased the saturation.
Violet
Violet is hard to find in nature. It’s often mistaken for purple. It is rich, mysterious, religious, regal, superstitious.
The penguin ice sculpture was taken on my phone and I increased the saturation and contrast during post processing.
The artificial flowers, with the contrasting green background, were taken during an outing to research assignment ideas. I managed to find good sources of colour, even in the middle of winter. I used no exposure compensation and changed the white balance during post processing to 8060K (slightly warmer than shady). I also increased the vibrancy and slightly increased the contrast using the curves control.
