No offense, but nobody can actually be a photographer, meaning being behind a camera and take photographs, and use LR 5-6 hours a day for 6 days a week.
You are joking right? 5 hours a day for 6 days is 30 hours. There are many weeks, sometimes for months on end, when I spend 30 hours or more in front of Lightroom.
That time might include initial editing, image adjustments, and then printing pictures. We mainly do wedding work and so are dealing with hundreds of pictures at a time.
If we do 2 weddings on a weekend that may give us more than a thousand pictures to go through, of which 400 would need to be printed. With LR2 I find that I rarely
need to use Photoshop anymore, so spend a lot more time in Lightroom.
Of course, and I do not know if you are a professional photographer or not, you may be thinking of only a 40 hour working week. I wish!
Update. Just had a look at your website and I guess you are a working photographer! Very nice work by the way.
