f/8: Capturing the Details of Buildings and Structures

If you want to take pictures of large structures that are a slight distance away, such as factories and buildings, we recommend using f/8. The image that you get will have minimal out-of-focus areas, with details sharply depicted throughout the entire frame. It’s also worth noting that f/8 is also an excellent choice for shooting natural landscapes and street photography. (Reported by: Teppei Kohno)

f/8 keeps structural details sharp—as long as you are not too far away!

When photographing streets, buildings and factories, what you want is to depict concrete and metal textures in a clear and sharp manner.  At aperture setting f/8, as long as your subject is not too near (for example, at least around 8.25m* away on the EF50mm f/1.8 STM and an APS-C sensor camera, roughly equivalent to a building across a two-lane road), the depth-of-field at f/8 should be enough to keep the image sharp all the way to infinity, and even capture the texture of the metallic areas accurately so that the overall image looks true to life.

* Calculated based on half the hyperfocal distance. The hyperfocal distance is the minimum focusing distance that provides maximum depth-of-field and depends on aperture setting, camera sensor size and focal length. Try out this depth-of-field calculator to see the results for another focal length. Generally, hyperfocal distance also increases with the focal length.

Going too narrow can backfire

If the subject is very far away, narrowing the aperture any more than f/8 will not make much of a difference to how sharp the image appears. In fact, over-narrowing the aperture may even cause the image to lose its sharpness due to a phenomenon called "diffraction", where light waves entering the lens are blocked by the aperture blades and forced to bend, resulting in an image that is less crisp.

If you feel that the f/8 depth-of-field is not large enough, you can narrow the aperture slightly, but be conservative about your adjustments. Most photographers will try not to go beyond f/11 unless they have a good reason, such as if they want to create a starburst effect and the image quality is of secondary priority. 

The three images below, shot at f/2, f/8, and f/22 respectively, show how aperture affects sharpness.


Factory at f/2

f/2, 1/4 sec, ISO 800

Close up (f/2)

At f/2, the lines appear blurred ("soft") due to the shallow depth-of-field. The purple discolouration (colour fringing) in the image are a sign of axial chromatic aberration, which is more likely to occur in images shot at wider apertures.


Factory at f/8

f/8, 4 sec, ISO 800

Close-up (f/8)

At f/8, the lines appear sharper and crisper.


Factory shot at f/22

f/22, 30 sec, ISO 800

Close-up (f/22)

At f/22, there are beautiful starbursts from the lights. However, the lines appear soft due to narrow aperture diffraction.

Here is a GIF of the close-ups for comparison. Do you see the difference especially in the outlines?

Tip: If your scene has elements that are slightly further away, you will need to use deep focus technique. Try f/11 for a start. 


Bonus technique: Enhance the metallic feel with 'White Balance -Tungsten Light’

When the lighting around your subject has a unique colour cast, such as in the example at the top, it could also be fun to play around with the White Balance (WB) settings. You may even end up creating a photo that has a different visual effect from the actual scene. For nightscape photos like this one, we recommend the ‘Tungsten Light’ setting. This imparts a bluish hue, transforming the mechanical-looking factory nightscape into one with cool, surreal feel.

WB-Auto: This has a somewhat surreal look, but there’s no uniqueness to it.
