The wonders of modern technology never cease to amaze me. Growing up with a traditional camera and film and understanding the complexities of color film and the magic of color film processing, was indeed a fascinating period. Apple's Aperture 2 and Adobe Photoshop Lightroom 2 supports 16-bit print drivers for Epson and Canon printers, allowing you to produce high-quality output with smoother gradients and better color fidelity...no darkroom needed.

However, you do need to ensure that you have a consistent 16 bit workflow from the image capture, through to image editing, and finally to the print output. This means that you need to capture your images in the RAW format. It is only with the RAW format that the image will have the required image data to make a difference on the printed output.

Of course, when making a decision to purchase a digital camera, you need to look at the number of pixels the sensor will capture. Most low end digital cameras, the consumer models, will not take RAW images, so those cameras cannot even be considered. You need either a very high end prosumer model or preferably, a DSLR. The minimum number of pixels needs to be at least 6, but more is better.

Currently, only the Macintosh operating system supports 16 bit printing. This may change in the future, but for now it is Mac only. And of course, you will need to be using the latest versions of Lightroom and Aperture. If you do not shoot in the RAW format, but instead shoot TIFF or JPEG, then you will only be able to capture 8 bit image files. What does that mean?

The mathematical formula for working out the possible number of colors in an image is as follows; for an 8 bit image, this means you are capturing up to 256 possible variations in the brightness of each of the Red, Green and Blue pixels, so you would multiply 256*256*256 for a possible maximum number of colors of 16.8 million. This equates roughly to what the human eye can perceive. However, if we look at 16 bit images, each pixel has a possible brightness value of 65,536 values. So, if we multiply 65,536*65,536*65,536 and get about 280 trillion colors, a little more than what the eye can perceive.

So, will all these extra colors really make a big difference on the final print. It is unlikely that in most situations, that you could really detect that difference, but in prints with lots of gradients, like sunsets with subtle red, blue, orange graduated skies, 16 bit could make a significant difference. This is where the benefit of 16 bit comes into it's own, on subtle gradations or images with large color gamuts.
