As winter sets in, I find that the opportunities to take photos get harder and harder to find. The hours of daylight are shorter, and tend to be while I’m at work – and the weather conditions and lighting all get worse. As I find it impractical to carry bulky camera equipment with me everywhere, instead, I try to carry a small compact camera with me. I can then grab a few minutes taking photos if I find a nice scene or conditions are good.
At the same time, I also like setting myself little challenges, to see how far I can push the equipment I’m using, trying to get the best from the situation with simple gear.
Recently, I came out of work and I was walking near St Paul’s cathedral in London. I spotted an opportunity to shoot the cathedral (a very over-photographed building) through an archway, to form a nice “frame within a frame”. The camera I had on me was my ten year old Casio Exilim EX-Z120, which I recently bought second hand for £6.
The camera itself is nothing special (though I am rather fond of it, because it has a view finder, which comes in handy on bright days, and takes pretty decent “snaps” for most casual purposes). It is pretty limited, though, in terms of its metering capabilities, low light response and dynamic range. It’s therefore a challenge to coax the best out of it that you can. Here is the final shot, which I will then give a bit of background to:
Overall, I am quite pleased with the result, but to get the photo to this state required a fair amount of post-processing (digital manipulation).
The shot, as taken, looked like this:
You can see from the image, that the camera was not able to expose well for the darker sections of the image and the sky at the same time, lacking the dynamic range to do so. The image also struggles because the parallel lines of the arch converge. This could not be avoided in-camera, because it was not possible to stand any further back (my back was against the wall). I had to look up to frame the image. Sure, it would be possible, with an expensive tilt-shift lens on a DSLR, but that would have been very impractical – so you have to rely on software, such as Photoshop elements to correct the so-called “barrel distortion” in the final image.
Similarly, the original needed quite a lot of levels adjustment to bring up the dark shadows of the early evening, and lastly it needed the sky restoring to it’ blue glory. The sky was shot at the same time, in the same place, but correctly exposed for the sky only. With multiple exposures, it would be possible to achieve the same or a similar effect using HDR compositing. In my case, I simply cropped a square of sky and dropped it into the original image as a new layer and used the “darken” tool in Photoshop elements. While some may view this kind of manipulation as cheating – all I was doing was restoring what I could see with my own eyes, but the camera was not capable of capturing directly.
Ultimately, you have to make the most of what you’ve got!
