Digital Vs. Digital Projection

Recently in the world of cinema, there has been a great shift from the analogue format of film to digital projection. There are many who suggest that one format might be better than the other. I was working as a projection and sound technician for a major cinema exhibitor during this shift, so I have some insight into the similarities and differences in the two technologies. Though I enjoy servicing film projectors more than digital projectors and I have nostalgic feelings about analogue film in general, it is clear that the digital projection platform is far more versatile and has more potential for being improved even further in the future. Digital and film projection actually have a few things in common. Firstly, the majority of both…show more content…
Modern digital projection technology only relatively recently surpassed 35mm film in terms of subjective image quality perception. Whether or not digital image quality has surpassed 70mm film is still debatable. on the other hand, with film projection, the image is physically developed on film and there is no resolution, or you can say the resolution is infinite. It’s like trying to describe a perfect circle by describing it with squares or straight lines. So, the quality of film images depends on the process used capture, develop, and duplicate the original image. An advantage of digital over film is that the projected image will always be the same across all digital projection systems. Since every digital projector is fed the exact same pixel data, the position and color of the pixels in relationship to one another will be consistent. With film projection, the image is physically developed on film, so there are greater variations in image and color from one print to the next. Typically, this difference is negligible and not even noticeable, but there are differences. The way the projected image is produced on each platform differs as well. Digital projection is essentially individual 1’s and 0’s, strung together in binary code on a hard drive, that gets interpreted by a computer into pixel data which is sent to either three DMD chips (DLP) or SXRD panels (Sony digital). Each of the three chips/panels handles one color, red, green, and blue
