Join Mark Lefitz for an in-depth discussion in this video Creating a 3D camera to match the plate, part of Photorealistic Lighting with Maya and Nuke (2012).
To match the Maya camera to the camera that shot the plate, we need to get the…metadata from our RAW image.…This data will tell us our file size and lensing information that we…can replicate in Maya.…Open Photoshop, and click+drag our RAW file into the application.…We get our Explorer window, we click+drag in our CR2, which is our RAW image, and…that will bring up Camera RAW.…Now, we are not going to do any color correcting here; we are simply going to…use this to get the information from the lens.…
We notice it was taken with an ISO of a 100, the lens was shot with 24-105, and…it was shot at 50 millimeters.…So, what we want to do is, in Maya, we want to create a 50 mm lens based on this data.…We are done with that, and let's open up Maya back to our shading file where we left off.…First thing we want to do is we want to create a single node Maya camera, and…name it something like shotCam.…So, let's go up to the Create menu, Cameras, and we are going to create a…single node camera.…
In the channel box, we're going to select that, and we are going to call this shotCam.…
