You'll hear that every time you talk with a photographer: "Take a camera everywhere you go". I have mentioned that already a couple of times on my blog already but I'll add something this time. Therefore, "take a camera everywhere you go, EVEN BOWLING!".
But seriously, the whole fuzz around taking a camera everywhere you go is really about 2 things:
1) you don't know when & where to expect a great opportunity for a picture and having a camera with you (almost) all the time makes you ready for taking that great and unexpected shot;
2) practice makes perfect - it's a no brainer; the more pictures you take, the better photographer you become.
I went bowling in Brussels with a group of friends a couple of weeks ago and I took a camera with me (surprise, surprise!). To be honest with you, I didn't expect to take any pictures but I ended up taking few shots with my trusty Nikkor 35mm F1.8 DX, which is a great lens for low-light situations. Even though Nikkor 35mm F1.8 DX is a very bright lens, I still had to crank up ISO to get more or less sharp shots but I also spent some time on getting blurry & motion-like pictures.
