In this video I talk about one of the most common topics in filmmaking which is exposing your image properly for minimal noise and FPN, while retaining maximum dynamic range in the shadows and highlights even in low light scenes. I'm explaining what the ISO is, what it does to your image and when and how you should use it. I'm also going through how the shutter speed, frame rate and lens aperture affect the light coming through the lens. I'm using Blackmagic's new Ursa Mini Pro 4.6K G2 camera as well as the Pocket Cinema Camera 4K, with plenty of examples for exposing your images including underexposing and overexposing. Finally I'm talking about Pocket 4K's Dual native ISO and how it changes things compared to cameras with a single native ISO. The same theories and techniques can be of course applied to any other camera. Dealing with images that were not exposed properly and working with noisy footage and FPN is discussed in another video. Thank you for watching! #bmpcc4k #umpg2 #blackmagicdesign *there is one little mistake at the graphic at 9:17. The 90 degrees rotating shutter graphic should be 270 degrees with the 90 part being the one that is uncovered (and light goes to the sensor through it). The rest of the shutter graphics are correct.
