This is, of necessity, going to be a short post. I am just a bit fried. It is now Monday evening, and I am writing my post for Tuesday (I always post in the evening and schedule for 12:01 am - but you knew that, right?). It was a miserable day at work - things we had done Sunday backfired on us today and it was a scramble to set things right. All day.
Tomorrow - a post on how a fast lens will help you make a great photograph.
