Most of the dream cameras I have read about concentrate on mechanical attributes of the camera itself. Actually in that vein, I want something very practical, not dreamy.These days of course digital and with a large image sensor, but not quite fill-frame. A 3:4 aspect ratio would suite me better. As for a lens, I would be happy with a modest, fixed (not interchangeable) modest speed zoom with a focal length range equivalent to a 35mm camera a 24 to 150mm range, but with a true macro focus capability at about the equivalence of 80mm. Auto-focus is now quite reliable, so my desire would be to have an efficient and comfortable zoom, optical viewfinder. And even an LCD viewer on the back of the camera I find is not needed if it is replaced with a plug in 7 inch tablet screen. Of course this plug-in screen should be made with a built in folding shade, and has its own separate battery power.
What would make the camera a dream in my view is that the camera controls are user selectable rather than the camera company designed over automated and autocratic regimen. Let the user acquire an application to control the camera in the same way a computer user can select an application to run on a computer.
My understanding is that a film scanner and a digital camera are very much alike. But the design of the senor in a scanner is in a linear arrangement so fewer sensor sites are needed and function repeatedly as they pass by the film surface. While a camera has more sensors arranged in a plane on a chip that are all exposed at the same time. The data received by a scanner and a camera is essentially the same, a raw file of measurements by the sensor sites that form a pixel image. So why can’t a camera then be arranged in the same way a scanner is in the way the image is managed?
You or I can get an application that will open a Raw natural file that we can adjust, color correct and edit to a finished image ready to print. So why can’t we do that with a dSLR camera? We can get Apps for doing almost anything with an iPhone or an iPad, but not for a digital camera. Cameras are closed systems with the manufacturer in complete control. So shouldn’t they be open?
I would like to be able to make a preview exposure, adjust, color correct and edit it and then use all of that to make a finished photo file directly with my camera. It should be possible and just as easy to do as making a finished image file with a scanner. That is what would complete my Dream Camera. What we have now is inefficient and wastes a good part of what a digital camera captures, and it could be much better. But camera makers want to be in control and don’t want you to have any.
