The world of projectors

Today my mentor and I got into the topic of projectors. Projectors are probably the most important part of theaters. Back when good old film was the standard for shooting movies, every theater had film projectors. You would take the film and load it through all the gates and sprockets. When the film was set and loaded an intensely bright light would shine through the film and lens and then the film would project onto the screen. for the light they would just use a regular bulb but they started using xenon lamps. Then when everything went digital and theaters had to keep up and also convert to digital. a core piece of technology that's needed to help projectors function are digital micro mirror devices (DMD). As light passes through the DMD, it causes the micro mirror to split the light into red, blue, and green. depending on whether a projector is 2k or 4k, the micro mirror deice inside will have one micro mirror for each pixel. Projectors to correspond with different types of film; 8mm, super 8, 9.5mm, 16mm, 35mm, and 70mm(IMAX). There are so many digital cinema projectors that have been created; DCI, DLP, Stereo 3D, and Sony SXRD. DLP projectors were originally programmed 2k but soon upgraded to 4k. Their resolution is 1280 x 1024. Stereo 3D projectors use stereoscopic tech. Sony SXRD has 4k resolution. Sony had manufactured their own SXRD chip that worked with this projector. You can find most of these types of projectors at Barco or Sony. There's a lot more to learn about projectors and we're going to pick back up where we left off because if we continue my brain might explode from all this information.
