Shift Your Perspective



It is a universally acknowledged fact that we, as people, love to document the places we visit by means of photograph. This travel tradition isn’t just limited to checking out new states or countries.

No, no, we do this all the time now, thanks to social media. We can post our “Hi mom!” pics from anywhere, even our favourite coffee place up the street.

Because we’re all a little guilty of using our phone cameras more than our actual cameras, we’ve probably noticed a difference in the field of view between the two. If this annoys you, there are solutions to help you capture more of what you’re seeing.

One of them is wide angle lenses. They don’t have to be extreme to get the point across, either.

Essentially, they let you fit more into your field of view which can lend to better, more expansive looking skies and landscape shots. If you’re travelling, this is a nice little option.

Another significant feature is that they can make small spaces look bigger or truer to life. This is a much better way for real estate and interior photographers to capture a broader, more realistic view of an entire room for clients.

These are the kind of photos that get people interested in visiting your space or inspecting your properties, so that’s really something to keep in mind if you provide these services.

As a comparison, we shot the interior of a car because that’s nice and cramped.

We shot on an APS-C camera with a common kit lens and a wide angle prime. While the difference doesn’t seem like much on paper, you can see it in the pictures. The wide lens makes things look more spacious or further away. For a more dramatic comparison, here’s what a 28mm f/2 looks like next to the same 12mm f/2.

 Left: The 28mm f/2 lens becomes closer to a 42mm on APS-C.   Right: Still the same 12mm f/2 as above.

Yeah, this is way more noticeable. You can see that, even from the same angle in both photo sets, the space changes quite a bit as your field of view increases.

With this increase, however, there’s a conundrum; wide angle distortion.

This becomes very obvious when photographing humans with these lenses. Let’s just say they’re not ideal for portraits and leave it at that.

Most often, you might notice distortion around the edges of your image, especially when taking photos of things like buildings.

The nature of their optical design is such that, when pointed up or down, wide angle lenses can cause make vertical lines appear to pinch in at the top or bottom of the frame depending on how your camera is angled.

This is due to the convex curves of the glass elements. Light can’t enter the edges of a lens the same way it enters at the centre. So in exchange for the increased view, you lose a bit of clarity around the edges.

Enter the tilt shift lens.

These highly specialised lenses are all about perspective and sharpness. They come in a range of focal lengths, including wide angles.

Dang, is that lens broken? Nah, it’s just a Tilt Shift lens doing what it does best.  

As the name suggests, you can physically tilt and shift the optics within the lens, meaning you can setup your camera and make what seem like physical adjustments without actually moving it.

The shift function provides up and down, or side-to-side movements while keeping your sensor and focus planes parallel with the vertical object you’re trying to shoot.

If you’re wondering what the heck that looks like, don’t worry, we’ve prepared a diagram.

On the left, both focus and sensor planes are not parallel to the vertical buildings. On the right, they are.  

As you can see on the left, the sensor and focal planes are not aligned with the vertical rise of the buildings.  The top of the building could be distorted by the top part of the lens.

On the right, both planes are parallel with the buildings, but lens has been shifted upwards to put the buildings in frame using the sharper, central part of the lens.

So instead of composing your image by moving your camera around, you can do this by aligning it with the horizon and just shifting the optics up or down to get your ideal framing.

Once you dial in the perfect amount of adjustment, you’ll notice corrected vertical distortion and better edge-to-edge clarity. This means you can take advantage of the wide angle field of view to capture large structures in their entirety with better accuracy and sharpness. 

Here are some photographs we took with a tilt shift lens to show the difference it can make.

You can see what all of this looks like in the above images. The one on the left seems fine until you add some handy lines that show the verticals are actually at an angle. If those red lines were long enough, they’d eventually converge.

On the right, the lines are straight up and down. This was achieved by using the shift function on our Canon 50mm f2.8L Tilt Shift lens. Side by side, the difference is pretty significant.

Where these lenses truly shine, however, is in creating large scale prints of architecture or cityscapes. They let you capture beautifully sharp photos of buildings and structures without distortion to distract from your overall result.

Now, as you may have guessed, the shift function is only half of what these lenses can do. Stay tuned for our next instalment where we explore the strange and amazing tilt feature!

Shooting Buildings and Monuments - get a new perspective!

By Marc B

Shooting buildings and monuments can be very challenging to get right.  It’s easy to stand in front of a building and snap off a few shots, but what does it take to get a truly exceptional photograph?  There are many things that need to be considered when it comes to this type of photography, not least of which is location, light and perspective. 

Location
The best part of the photo taking process is actually finding either a building or monument to photograph, and finding a different perspective than anyone else.  This involves a bit of walking and looking.  You don’t need to shoot a well-known landmark or building; indeed they have all been photographed to death, so it’s good to find something a little out of the way that may not get the attention it deserves.  I have seen amazing photographs of drains, old petrol stations and even car parks. The limit here is your imagination and skill in capturing a compelling photo of what could normally be considered a ‘boring’ subject.

Lighting
Here is the real challenge.  Getting the lighting right is really what photography is all about, but how do we control the light on something like a building?  A little bit of patience is required as you will need to wait until the light from the sun (or moon!) is at just the right angle for the photo you want to achieve.  There are a few Apps that you can get for smartphones that can tell you where the Sun will be at any time on any day for the chosen spot. Knowing this information will help you plan your timing to be on location.  A nice technique is to wait until ‘Golden Hour’ which is a time just after sunset where the sky takes on a nice deep blue - this lasts for varying amounts of time depending on the time of year and your location.  The lighting of ‘Golden Hour’ adds great colour to the sky while at the same time leaving enough light to have some details in the shadows of buildings.  

You will definitely need a steady tripod for this kind of work as your shutter speed will be quite long, particularly if you are using a low ISO (which you should be).  Also a cable release would be very useful here.

Change your perspective
Here is what almost everyone does: they see something that looks like it would make a good photo and they lift the camera to their eye and take a shot.  This ends up looking like every other photo of that building (or waterfall or whatever) ever since cameras where invented.  This is where you need to get creative.  Think about the perspective you want to use to make your photo different (changing lenses does not alter your perspective; it changes your angle of view only).  Can you get up high and take a photo from a nearby building?  Can you find somewhere that allows you to lie flat on the ground and shoot up at the building from an extreme low angle?  Try to think of anything that will give your shot a wow factor that is different from the standard point and shoot mentality.  Lens selection is also important. Do you shoot with an ultra-wide angle?  Stand back and shoot with a standard lens and get straighter vertical lines?  If you have the time, try as many options as you can.  

Patience
Above all you will need patience - finding the location, working out the best time of day for light and then nailing the perspective will take time. But in the end you will end up with a photo like no other - one with some thought and planning behind it, which will stand above the average snapshot.  Get cracking!  Feel free to share you results with us and remember that the first 10,000 shots are the worst!

Recommended equipment:
  • Lenses of varying focal length but particularly wide and mid-range lengths such as 10-22mm, 24-70, 18-55
  • A sturdy tripod (essential)
  • A cable release for your camera
  • Filters like a Cir-Pl, ND and graduated ND filters are great for certain situations (take a look at our recent blog on the Benefits of Filters)
  • Lens hoods can be helpful when shooting outside
  • A torch if you’re shooting at night
  • A weather resistant camera bag
