Another accessory that is also very important is Follow Focus, which has long been used by professional film camera teams, but with the advent of cameras to start recording videos, this accessory is necessary for the general audience of filmmakers and I will explain why.It all starts with the use of cinematic language in HDSLR video productions and large sensors (CMOS) and digital cinema cameras, these large sensors, when exposed to a certain amount of light and large diaphragm openings, cause a reduction in depth of field.in the scene, which requires a constant correction of focus.This is where the tracking approach comes in to help with these fixes.
It is mounted next to the lens, using brackets, gears, crowns and dental rings to adapt the lenses to its mechanical system, transferring the focus operation to the side of the lens, this making it easy for the cameraman or camera assistant to make the necessary corrections . , but just a detail, this assistant must be very well prepared and trained, so much so that he moves up the category and is now called a cameraman assistant, focusing on a professional capable of making focus corrections, in addition to his usual functions. To get an idea of the importance of Follow Focus, in a scene in motion using a 35mm lens, traveling sideways, or getting closer to the recorded object, many focus marks will be needed. , that’s why in this great accessory there is a white acrylic part exactly so that the focus artist can mark each focus shift in the scene. Today there are several types of Follow Focus on the market, which work with a wireless system and with digital markings of the focus corrections, especially when this correction must be made from a crane, a steadicam, a drone or other specific equipment. I hope you liked it and my next post will talk about it. 4k? !!!!
