Digital images are scanned and printed from any digital format, including, but not limited to, JPEG, RAW, TIFF, TIFFX, PSD, PSDX, AVI, and XQD. The processing steps used to convert image files to digital pixels in a camera-like way can vary depending on model(s), camera, lens, and the type of digital camera.
While your camera is scanning the digital images, your camera may be using digital processing to achieve high resolution and/or smooth color contrast. The resulting digital image files can have a lot of processing done prior to being sent to your camera to help optimize the resolution. If you choose to use your digital camera to process the images, be aware that some of the process steps may affect the quality of your photographs. For example, as the images are being processed, colors may shift as the sensors are calibrated and calibrated image data is entered.
The following images are examples of images with the same photo data but which are processed in different ways which may result in your having fewer images captured.
Color Depth/Gamut (CMYK: CIE 1976) is an aspect of color that is dependent on the amount of red and green light reflected from the sensor. As photons strike the sensor, the sensor is exposed to some of the light, and the red, green and blue waves are sent to the CIE 1976 color space, while the blue wave is discarded. It’s this amount of light that is sent that determines the amount of blue and green in your images.
Color Depth/Gamut (CMYK: CIE 1931) is an aspect of the color in which the number and quality of photons that are received by the sensor are important (see color gamut for a fuller explanation). The darker the color, the greater the amount of light transmitted to the sensor, which is what allows for the highest brightness or color fidelity. For color reproduction, that means that you’ll have more light reflected onto your images than that received by the sensor (or film), while for color reproduction, you can get better color accuracy without as much processing. This is also true with different lens types, camera and lens types and lens types used for exposure.
