This post isn't all that interesting, but it was a nice afternoon today so I went over to an old abandoned pre-fab cement factory near my house to get some fresh air and take some shots for practice.

I took a couple of infra-red shots at the start. One of them was mildly interesting because a Magpie was sitting on the fence but flew away about 1/2 way through the 20 second exposure, leading to a ghosted effect.

I tried a little experiment to remove the "hot spot" that is characteristic of infra-red shots taken with a 300D and 350D where a central portion of the image is noticably lighter than the rest of the image. After taking some infra-red shots, I would then take another infra-red shot of some empty sky at the same aperture... this basically gives a blank shot with the hotspot as the ONLY thing in it. This 2nd hotspot image can then be inverted and "subtracted" from the detailed image to reverse its effect. I've done this in the shot below:

Although I took a couple of infra-red shots, I was mainly concentrating on texture, lighting and colour with non-IR shots. Below are some of the least boring examples... but unfortunately I didn't stumble across anything that really got me excited... so I'm not quite sure why I'm posting these. I guess to ask "Can you tell what I was trying to achieve?" and "Did I achieve it?"
