Singing the Praises of Ultra-Wide
Monday, November 30th, 2009I remember when I first started on my lens quest, I didn’t even consider an ultra-wide lens. I thought that 21mm was wide enough for me. It wasn’t until I received the DA 12-24/4 that I started embracing the idea that not all keepers had to have bokeh (yeah, I was quite smitten with being able to have a shallow depth of field for longer than I care to admit).
12mm on an APS-C or cropped sensor isn’t even that wide, really – it’s the equivalent of 18mm on a full-frame camera. But it still offers a full 90° horizontal field of view compared to 67° for the widest view of most kit lenses on a camera with an equivalent sensor (18-55mm).
I’ve had trouble incorporating it into my style, which someone once aptly described as being very much “subject-background-and-nothing-else.” Most wide-angle shots that seem to work best either have
- something really interesting in the foreground, like large rocks on a coastline with the ocean stretched out beyond, or
- feature an eventful sky, which is kind of rare (I usually find it to be all blue or all grey) or
- uniform geometry (think of all the shots you’ve seen of the Vatican’s spiral staircase)
But I’ve worked to find shots that work with this lens, and one of the things I’ve tried to capitalize on is the same sun-flare technique I wrote about with the fisheye lens. It seems you have to be extra careful to have a clean lens, though – while most dust and dirt don’t show up in regular shots, the flare will reveal every last spot on the lens’ surface. It turns out that my lens is filthy, but I didn’t realize that before I took this shot. And as I didn’t bring any cleaning supplies with me on my hasty trip to the US, I’m kind of stuck with what I have at the moment.
Using a tripod while using ultra-wide lenses also seems to be a huge help. Unfortunately, I don’t have a tripod with me at the moment either, so everything I’ve taken recently has either been handheld or set on the ground. A tripod helps in two huge respects. First, it helps to get the horizon straight. While this should always be a priority regardless of which lens you use, it becomes especially important if you want to capitalize on the ultra-wide capacities of the lens. If you have to straighten the horizon in post-processing, you end up losing some of that impact, as most programs crop off parts of the photo to make the horizon straight- and at that point, you might as well have used an 18mm lens.
If you don’t have a tripod, then one of the ways to gain a unique perspective is to set the camera on the ground (pro-tip: do NOT do this on a road that gets a lot of traffic!). But ultra-wides present a problem here too. Depending on the lay of the land, you’re more than likely going to wind up with a photo featuring a huge area of asphalt and very little of your subject. I almost always have a tube of chapstick, so in a pinch, I just slide this under the lens, as far back toward the camera as possible, to get the camera and lens to point up. That’s how I took the following shot:
But I ran into a huge problem when I tried this tactic on a sunny day as we drove back through Georgia. The sun was directly behind the camera, and the lens and camera cast a shadow on the the foreground. Try as I might, I just could not get the lens up high enough to not get its own shadow:
I ended up cropping that bit out before I posted the shot on flickr.
Another thing you have to be aware of when using a super-wide angle lens is the amount of perspective distortion you can get. You can read more about this on wikipedia. For instance, I wanted to take a picture of this abandoned church, but any time you point the camera up, then the base of whatever you shoot is going to look huge and the pinnacle is going to look much smaller than it is in relation to the base. Just taking one step forward or one step back or a step to the left or right changed the resulting image tremendously. In the end, I compromised – I was as close as I could be to get both the steps and the top in the frame, but I wasn’t happy where that bright spot in the sky fell. Ideally it would have been behind the spire, but that would have meant moving to the right a couple of steps, which would result in the right side of the church looking stretched out. All of this things can be fixed in post-processing if you have the right software, but I’m trying to embrace the eccentricities of the lens.
But the main reason I’ve come to love my 12-24 is because sometimes, there’s just no other lens that can get that once-in-a-lifetime shot you see spreading out before you. I was already dangerously close to trespassing on someone’s property when I took this shot of a tree on a lonely backroad in Georgia – another step or two back, and I’m fairly certain I could have been legally shot by the homeowners. Instead, I was the only one shooting.
