Integrating a 3D Object in a 2D photo. How does Crop factor work?
on Jan 11, 2013 at 4:03:37 pm

Hi, I'm trying to get my 3d objects into a 2D environment, how can I get the camera and render settings right? I'm afraid I don't get how crop factor works, could someone explain it to me?

My photo was taken with a Canon EOS 5D, with a 35.8 x 23.9 mm sensor and with 43 mm of focal length but frankly, I'm not sure about what to do with that.

I don't really understand what you mean specifically by how does crop factor work? but I gather from what you are saying below may help.

To start you off.

Put your 2D image in the viewport background.
Create a box in the centre of the world and a camera pointing at the box - with a 43mm lens.

Then using your camera orbit tool you can manipulate the box in to the correct perspective, angle etc for your image.

REMEMBER Always move the camera and not the box - this way you have a straight guide box that works in side/top view, that you can then easily replace with your 3D model.
