With analogue you could point your finger at the costs for film and processing, contacts and prints by the lab. And… you made a nice markup… Certainly, with digital photography your cost for processing and film are gone.

But…

Besides the time and costs you make for ‘processing ‘ (creating a digital proof, basic colour and exposure correction), which is not done by the lab, but now by yourself; And besides the costs of ‘delivery’ (like CD’s and a server); You also make time and costs for ‘archiving’. Archiving will become one of the most important issues of digital photography.

I noticed it when I shot a first time digital wedding: Maybe less costs are spent to the lab, but -much- more time is spent in front of the computer.
