During the trip up north I noticed Dermot was making a lot of use of his macro lens. I mean, I took him to see some of the best coast line in the island and he stands on a beach with a macro lens taking photos of rocks!

He did get me thinking though. Maybe there is something to looking at the little things, even when the big thing is so pretty.

Now, I've tried ad-hoc Macro stuff out and about before. Never with much success. The only macro lens I own is also my telephoto lens and at 200mm it's probably not the best option out there for this sort of thing. Certainly, every freehand shot I'd ever tried didn't work up until now.

While shooting in Carnlough, I noticed one of the old trailers had a lot of rust and some odd paint splashes so I decided to give a real close up on this stuff one more go. but this time I tried something a little different.

Instead of sticking to my trusty aperture priority, I switched to shutter priority and set it to 1/200. A lot of the books and websites I'd read talk about reciprocal values for focal length and shutter speed and use mumbo jumbo, but in English I figure it means...

 

To avoid shake, your shutter speed needs to be at least 1 over the focal length of the lens.

50mm needs at least 1/50

200mm needs at least 1/200

etc.

Yeah, I guess you all knew that. (And you probably all know what reciprocal means as well). I'm slightly embarrassed it took so long for me to realise an answer to my shaky hand syndrome was to change modes on the camera.

Anyway, on with the rust.
