CCD technology has blown away all forms of film and super high resolution backs are available cheaply for almost all cameras, even brands from companies that went out of business years ago such as Contarex and Leitz among others. The camera body is now merely a lens holder and focusing aide. The first generation of these these affordable backs must be plugged into a PC via an rs232 port or something if you want to have super hirez 24 bit colour images that rival or surpass the best you could have gotten with your favourite film. . Later generations are even cheaper and have enough gigabytes onboard to allow the user to shoot dozens of pictures at even higher resolution and colour depth without connecting to anything except at print time. Of course the whole thing works so fast that the image can be captured in a fraction of a millisecond. Or fast enough and with enough resolution to see the land markings of a rotating incoming bullet. Anyway Here's my qiuestion, How does it work? Do I leave the shutter at B and softcycle the CCD or do I use the shutter and if so at what speed. Does it matter? This is a serious quuestion. I trying to get a feel for how this thing is going to work. If shutterspeed doesn't matter anymore then what happens to aperture. Do I set it at whatever I want with my only consideration being depth of field. Or does CCD have a low light threshold similar to film? Also, is there an inverse proportionality sort of thing going on with aperture? Similarly, is all brightness and contrast corrected during a printout/processing phase. If so then it sounds super: To be able to shoot at any aperture you want, probably your lens's favourite aperture without any consideration for illumination. I'm sure someone here knows more about this than I do and has had experience with current Pro-CCD stuff and I'de appreciate some ideas/futurism Best regards Javier
