Week Six: The Nature and Use of Colour in Design and Photography

I am going to look at methods withing RGB, these tend to completely change the appearance of the image with the techniques involved. I am using a shot which I took on holiday, this being an image of the street which leads down onto the beach, I want to try and change the image to make it look as though it has been shot just before nightfall,

To do this I set the image to RGB because I am going to look at the different channels within the image, these being most importantly Red, Green and Blue. This is the image I am using:

I then chose ‘Image > Mode > RGB colour’ I then opened my channel mixer so that each of the individual colours and their sliders were brought up to alter with…

I then need to focus on the output channel, this allows me to alter each of the colours by themselves instead of just diving straight into editing the whole image. I firstly started looking at the Red Channel and changed the values around until I got the perfect settings. The image needs to be as close to 100% as possible so it doesn’t show too much contrast, here I set the values to, red = +124%, green = +12% and blue = -34%. The contrast should also be moved down to +2.

I then chose the Green Channel, the settings should be, red = -2%, green = +102% and blue = 0%. The contrast should also be 0.

Finally I chose the Blue Channel, the settings should be, red = -6%, green = -6% and blue = 100% and the contrast should be -2.

This gives off an amazing golden tint to your image and makes it automatically look like it had been taking at a different part of the day, here is a comparison between the original and edited:
