Post Processing – Colors Casts

'Twixt Autumn and Winter - Varina Patel

It is well known that colors can effect the mood of an image. Blue, for example, is associated with feelings of calm – azure summer skies and deep lakes… and cold – winter scenes of snow and freezing glaciers. Most viewers will associate a chilly feeling with an image of ice – like the one above. But how many will notice the subtle blue color cast?

Without a direct comparison, it’s difficult to see the blue cast at all. Take a look at the image below – you can see that the original image is on the left. On the right, the color cast from the ice has been completely removed. Although the texture of the ice is preserved, the chilly feeling is lacking. This subtle change reduces the overall effectiveness of the image.

During processing, it is important to be aware of slight color casts like this. Think about what you are trying to convey with your image. Do you want your viewer to perceive a sense of calm and cool in your image? Or are you trying to invoke feelings of warmth and comfort?

About Author Varina Patel

There is nothing more remarkable to me than the power of nature. It is both cataclysmic and subtle. Slow and continuous erosion by water and wind can create landscapes every bit as astonishing as those shaped by catastrophic events – and minuscule details can be as breathtaking as grand vistas that stretch from one horizon to the other. Nature is incredibly diverse. Burning desert sands and mossy riverbanks… Brilliant sunbeams and fading alpenglow… Silent snowfall and raging summer storms… Each offers a unique opportunity. I am irresistibly drawn to the challenge of finding my next photograph, and mastering the skills required to capture it effectively.
