Last week I had two job come out of nowhere: A product shoot for maloof money cup 2008, a skater competition with a huge grand prize of...$100,000?... and a portrait shoot at the Bellagio for a couple who are getting married on the 25th. There was no model for the product shoot (it was apparel), so I had to make do with flat backgrounds and clothing shots, but they came out well enough. The portrait shoot seemed to be successful, and I got a larger variety of photos out of it than I had first believed.
Some of the exposures had to be brought way up in Lightroom, which seems to be very good at hiding the truth from me about actual defects in the image.
This experience brought me to the conclusion that I absolutely must get some faster primes. I sold my 50mm f/1.8 II (in this same week) because I almost never use it, but immediately I began to feel insecure and wished I had something equally fast. (Update: Bought an 85 f/1.8 and 135 f/2 since then, and now I'm spoiled even more and want a f/1.4 or f/1.2 lens!)
