When I first switched from film to digital I was shocked at the amount of time that digital photogrphy took out of my shooting day. Every day there was an extra 2-3 hours that I had to suddenly be renaming, downloading, backing up and captioning files. 2-3 hours out of what were already 14 hour days. That was time that I used to eat and sleep. At one NG meeting an editor said "listen I can not get that time back for you, it is gone..."
Someone tweeted me to ask why I am shooting corporate portraits. The answer -besides enjoying it- is that NG day rate has not moved in 10 years. Everyone I know has had to expand into commercial work to make the ends meet.
