Join Dave Schultze for an in-depth discussion in this video The new physical camera vs. the old default camera, part of Rhino and V-Ray: Rendering.
This next topic covers the difference between the two V-Ray camera types. The original camera type was known only as the default camera. It simply rendered whatever the perspective window was showing. If the scene was too bright or dark, you might have to adjust the lighting. The materials and backgrounds repeatedly, until the render finally looked okay. That's actually what I did for many years. The new fiscal camera offers a far better approach. It's designed to act just like a real point and shoot camera, which many people already know.
It can eliminate a majority of the usual tweaking. Let's review the basic settings and how to use it. We're going to access the camera by going to the V-Ray options editor, and right here towards the top is camera. Without the physical camera selected, the default camera will be used. I recommend starting with the following defaults. Physical camera on. Shutter speed of 30, F-number at 8, and Film iso at 100. Also, it's extremely important that the exposure button be selected.
Otherwise, its physical camera will not work at all. Back to the most important setting, I would recommend using shutter speed for all of your controls. For example, is the scene too bright. Well, just use a faster shutter speed. For example, at one 30th of a second. You can speed up to one 60th of a second, and that should fix most problems. Also if the scene is too dark, then just slow the camera down. For example, going to one 15th or you'd type in 15 here, for a 15th of a second.
If your settings are radically different, for whatever reason, you can always reset them back to the original, by clicking up here, at the top under load defaults. Lets select that and go back to camera, which is closed up and there is our one 30th of a second with all the other settings we just discussed. One final note. I would leave vignetting off. We're going to cover that a little bit later. Many people, myself included, started using the default camera and just continued out of habit. I never even noticed the physical camera, since in wasn't turned on by default.
If you are used to the default camera and then transition to the physical camera I guarantee you will see a nice increase in work flow speed. If you are brand new to V-Ray, even better. Just use the physical camera like I will be doing for the remainder of this course.
