In photography when you've left your specialist kit at home and macro isn't an option you have only one choice...

Pop a 50mm lens on your DSLR and get in as close as you can - mine focuses down to approx. 8 inches (20cm) and that means I can still grab images like this one.

Now I'm not saying this image is in any way spectacular, but it's quite acceptable as a close shot. Of course it doesn't really compare to using a macro lens, which allows you to get in very much closer...

...but even so, geting up close and personal to your subject can be a lot of fun. :yes:
