Studying Puddles

Rain is part of the environmental cycle. So rain is seen every now and again, whether we like it or not! So it makes sense to produce 3D scenes that include wet surfaces and puddles. In this article I will be studying how rain affects materials and how to re-produce them in the virtual environment. To start I set out after a rainy day to take some photo’s in my local area. Paying particular attention to how rain affects tarmac. The way light bounces back from the wet tarmac really equalises the scene.

This is the result of the tutorial video. This gave me a node setup I understood by following the tutorial. So adding modifications is easy and understandable. From the result I highlighted areas for improvement. I wanted to take full advantage of the displacement map; so that the water slips into the lower spaces in detail. To do this I multiplied the bump map in the material nodes to get this result.

PentaxMX

My first photographs using an old SLR, Pentax MX. I was worried all these photos would be either over or under exposed, thankfully my shutter-time judgement was correct. Using a fixed wide angle lens with a completely open aperture was a good first choice, this gave me enough light to play with. I love the warm and green colours produced by this film, the picture inst completely sharp but gives a soft feel.

Aeolian Light

A large outdoor light installation in Salford Keys, This large cubic array of lights change colour to the wind and your movement. Walking through the tentacle like dangling lights feels much like a scene from avatar, this immersive experience feels warming to the eyes despite the actual freezing feel. Salford keys is very open space and modern, a location to revisit.

Experimenting with long exposure has helped me understand more about my camera and how it works, for this project I went to an abandoned barn that would of been pitch black without my torch. I noticed I could create complicated looking lighting setups just using the one torch. A tripod was particulaly important to keep the camera steady while taking these 30″ long exposures, this also allowed me to move around with the light.
