Light is Everything!

Frost on the Punkin . . .er, Window

Whilst enjoying my morning cup of coffee, I looked out and saw that it was another ridiculously cold prairie morning. It was -28ºC raw temperature, and then with the wind it was actually -39ºC which is insane. Why do we live here?! 😉 Oh well, gotta take some pictures. I looked at our patio door, you know the old school, nasty, uninsulated, aluminum, gong show, resource wasting kind. It was nicely decorated with frost. I quickly ran and grabbed my D300s, my cable release, tripod and 105mm Macro VR lens. I set it up at 1:1 focusing and made some compositions.

I just love Macro! There is so much going on all around us. If we would only open our eyes to see that we are surrounded by zillions of photos all the time! 🙂

One other insight from the photo shoot this morning. Camera lenses suffer from two main pitfalls. Chromatic Aberration at really low f stops and Lens Diffraction at really high f stops. All lenses suffer from these things, some are better than others. I took two photo crops to illustrate Lens Diffraction (the image gets tooooo sharp and becomes blurry)  as a comparison at f/18 and f/51.

Major Diffraction at f/51

Nice and Sharp at f/18

This is where knowing your lens and doing your own lens sharpness testing is a real benefit. You’ll know how far you can go before your lens diffraction gets so bad it actually wrecks your shots. This is more applicable to landscapes where you want a higher f/stop for lots of detail, but it also applies to macro too! 🙂 Click the images below for a larger look.
