(Semi-) Pro Equipment - NO rules!

Challenge #6 in the Who Knows... series. Hosted by blosshapperter.
Challenge has finished
This is the complementary of the standard equipment series. Get out your full formats or even middle formats and show us money-starved how hopelessly we fail with our standard equipment. This challenge is NOT restricted at all. You might be interested to put in with and without post in both challenges. You might be tempted to put in a link to the other into the description field... This is a 'beginners challenge' hoping to attract some pros showing us how to do it right. We want to learn - please comment the pictures! Please be creative!
