For the lighting I used standard Maya lights. I didn’t use Global Illumination and Final Gather. I also made other supporting objects for the scene; a tree used for a shadow, and there was also a white plane placed above in order to create the reflections on the wires and in the frog’s glasses.

For some haze in the air I made another scene with one light source. I used partiVolume and partiVolumePhoton mental ray shaders, which I connected to a container cube material and to a physical light (09, 10 & 11).
