Stuart Christensen is back with another Maya tutorial, this time looking at the MIA Exposure Photographic node when using a Mental Ray Physical Sun and Sky.

“Mayas default Sun and Sky system is set up initially with a MIA_Exposure_Simple lens shader which does not really give you great control over the look of your scene. Instead, you may want to consider using the MIA_Exposure Photographic lens shader for gaining way more control over the final look, and to help you precisely fine tune textures and colors. In this tutorial by Stuart Christensen, we’ll install and utilize an elegant MELscript by David Johnson of the DJX Blog, that will automate the process of connecting our Sun and Sky to the “ever so much better” MIA Exposure Photographic node, and review the settings and cover some common procedures for working with this camera tonemapper.”

    Hi,

    Thanks voor your tut. But I’m wondering, when I use the mia_photographic lens, all my lights (point, area) are not visible in my render anymore. What can I do?

      if the scene is really dark, you need to add a higher number to the cm/m2 field for the mia exposure node.
