Digital InfraRed Photography

I recently bought an Infrared filter for my new Canon 40D in order to try out some non-visible light photography. In this first article I will attempt to explain how to capture IR shots and then in the next post we’ll look at processing methods.

Off to the Wind Farm!

Rob Hudson and I take a trip to the Wind Turbine Farm just outside Cardiff. In the dark. With a video camera. Hmm…

Removing Streetlamp Casts from Night Shots

I’ve been doing a lot of night shots lately and after a lot of long exposures in light polluted areas, you get used to seeing that orange glow brought about by the street lighting.

Whilst out on a night shoot lately I used a function on the Canon EOS 300D to help combat the effects of the orange cast. The technique uses in camera White Balance correction.

Capturing Star Trails on a D-SLR

I wrote a tutorial on how to capture star trails like the ones above for the WelshFlickrCymru group on Flickr.

It is repeated here for posterity!

Long Exposure Theory

When out doing night photography like the shot above, you don’t want to waste time guessing what the exposure time should be (like I did here one bank holiday morning…)

The technique I use is to do a shot at a very high ISO speed and a smallish exposure time, then use that to adjust for composition and check the histogram. Changing the ISO from 1600 to 800 (for example, doubles the exposure time. So to get back down to ISO 100 requires a few doublings to get the right number.
