Again it was common to use a black and white CRT with a filter wheel. The host computer would write digital values, usually a scan line at a time. More modern film recorders (late 1980s) were digital. A common scheme was to have a camera pointed at a black and white monitor, with separate red, green, and blue filters that were switched in, usually by using a rotating filter wheel. Usually it took several seconds to 10s of seconds to expose each frame. You connected video signals to them, and the result would end up on film. What you ask for used to be common, and called a film recorder.
This is the only method that I can think of that you can do at home that will yield sufficient on-film resolution for display.ĭon't worry about trying to attempt colour film development at home, it is complex and expensive -just send your roll off for standard development. Compression rates of 10:1 or 20:1 yield little degradation in image quality.Inkjet printing is not an option due to the real-world resolution that could be achieved being very low ( 1/2sec) to negate any oddities caused by backlight/refresh frequency. Compression rates of 100:1 can be achieved, although the loss is noticeable at that level. JPEG involves a lossy compression mechanism using discrete cosine transform (DCT). JPEG is a joint standard of the International Telecommunications Union (ITU-T T.81) and the International Organization for Standardization (ISO 10918-1). JPG is a graphical file format for editing still images, it offers a symmetrical compression technique which is processor intensive and time consiming in both compression and decompression. The JPG file is a great format as it often manages to compress files to 1/10 of the size of the original file which is especially good for saving on bandwidth. The JPG format is often used in digital camera memory cards. The resultant 'lossy' file means that quality can never be recovered. JPG's are often used for web sites and email as they are generally smaller file sizes as they are lossy meaning that some image quality is lost when the JPG is compressed and saved.
