Achieving Photorealism with Hue and Saturation

In a previous post I said that the cartoon snails fit into their environment better than the frog because the saturation (vibrancy) of the colours more closely match the surrounding environment.

The intention of today’s experiment was to identify this is fact or myth. To this aim two images have been produced; in one image, the 3D element utilises the colour of its environment, in the second image, the colour of the 3D element is in strong contrast to the environment.

Looking at these two images I was pleased to see that my initial thoughts about colour are true. My opinion is that it is far easier to believe the green frog might have been photographed, whereas the red frog has clearly been added digitally.

It is important then that when trying to achieve photorealism, the colour and saturation of a 3D object should match that of the environment.

Still not convinced? Try adjusting the hue and saturation for yourself. If you find a setting that makes the frog look more believable, I’d be delighted to hear about it.
