Today I was playing with silhouettes (and my new 50mm lens) as the sun went down at the beach. Quite a bit of fun and something a bit different I thought. It was a bit more of a challenge than my lazy 18-200 zoom lens but it did me good to have to move around to frame up the images and I was pleased with the results.
I am VERY impressed with my 50mm prime lens, if you haven't got one and you have a DSLR get one as they are cheap and a must have! Check www.amazon.com for some great prices.
