It has never been so easy to make a picture like today. The digital revolution has made one of our most important communication media lightning fast, easier handhabborn and also cheaper. Film and photo engineering experience generational change, as they were known only by computer technology. The most best of the best has been unavailable tomorrow. Few powerful companies stuck billions in competing concepts, but also in advertising and marketing, and not always the best technology is committed by. We as a customer benefit from or numbers on it when we have set to the "wrong horse". Where is the development?
At present, the main argument for digital photography is the immediate availability of the results, without long waiting times and without the dependence of service providers. For that, customers (at least below the professional segment) partially took and take even significant limits of the image quality in purchase – too sooner the potential of analog technology was rarely exploited. Kinderbild, but not always upheaved, the subsequent control over the result is: The shift of the "darkroom" in the computer has brought us many freedoms, but also processes and decisions were caused, which were previously in the hand of professionals.
Photographers who received a perfect fit from the specialist laboratory, doubt their skills when their "developed" digital photos are now less perfect. Maybe nobody has told them that the digital technology, unlike the analog, has firm boundaries, lies beyond that with the best tricks no more pixel lashed out anymore. The most important of these limits are the 256 brightness levels per color that can be stored in a JPEG image file. The 8-bit "color depth" of such files optimally matched the performance of image capabilities as well as reproduction data many years ago, but remains clearly behind their possibilities.
Also the space is no argument today for low color depths and high compressive. Memory Cards with Gigabyte Capacitat allow the storage of hundreds of 10 MB of green image files comparable to the price of a brand film (converted to the frame) with the price of a brand film, but many times can be used. The technical requirements for "more bits per color" are therefore given, but are not always supported by the current software. We will show below how and with which programs you can work with RAW files and 16-bit files and what to consider.
