Magic Red ViewFinder is a powerful 3D viewfinder for professional filmmakers and photographers. It allows you to simulate the view of any camera/lens combination you will be using in your upcoming shoot.
Using this app, you will be able to determine the exact field of view for your future shot, as well as learn the correct angle of the camera and the best angle of the lens.
In addition to that, you can apply some commonly used color presets (also known as LUTs) to the live picture, which brings you even closer to the final shot.
You can also use the depth-of-field tool to calculate the near and far limits of the depth of field.
It is compatible with the following cameras:
Alexa, ARRI
Blackmagic
Canon
Sony
Panasonic
Magic Red ViewFinder is a universal app that works as a viewfinder for all cameras and lenses. It can be used on any device that is compatible with the app.
