An ultra-wide-angle lens is a lens that covers a focal length of less than 24mm in a full-frame equivalent field of view.  This includes prime and zoom lenses.  For zoom lenses, if the wide end of the focal length is less than 24mm, even if the long end includes or exceeds 24mm, it is considered an ultra-wide-angle lens.  Read this article and follow our editor to learn super wide-angle camera shooting skills.

1. What is a super-wide-angle lens good for?  

Ultra-wide angle lenses allow you to have a wider view of the picture and you don’t have to step back to get more of the picture, so photographers can’t be afraid to shoot badly in some narrow areas.  Using ultra-wide Angle lenses not only allows you to capture more of the scene but also makes the building look more magnificent because of the nature of the lens.  

Ultra-wide angle lenses can also be used to shoot people, and a little attention to the way you shoot them can make them look longer.  And ultra-wide Angle lenses can also take pictures of people in that kind of spatial sense, even better than telephoto lenses.  

2. How do ultra-wide angle lenses affect depth of field  

In photography, a scene is influenced by many different variables, such as aperture, focal length, distance from the camera to the subject, and sensor size.  Without a doubt, the focal length is one of the biggest factors affecting the depth of field.  

Ultra-wide Angle lenses have an extremely short focal length, allowing for a large depth of field even with a relatively large aperture.  Because ultra-wide Angle lenses can reach an infinite far focal length at close range, they are often preferable when it comes to sharpening both the foreground and the background in an image.  

In addition, one does not have to deal with the diffraction problems associated with using very small apertures.  Once the hyperfocal length is established and focused, even the larger hole image off / 4 can make the entire scene sharp from front to back when the ultra-wide-angle lens used in the mild camera-to-object distance appears.  

3. Super wide-angle camera shooting skills

One of the biggest mistakes many beginners make with ultra-wide Angle lenses is to compose them like they would with a normal lens.  This usually results in a lot of negative space, too much sky, and an empty foreground.  The main body of the scene and its distant surroundings end up looking insignificant because the ultra-wide lens makes them look very small.  

So how to solve this problem?  Since ultra-wide Angle lenses exaggerate the size of foreground objects relative to the background, it is best to use them close to the main subject.  The point is to highlight the subject so that it looks proportionally larger than its surroundings or background.  

This makes the ultra-wide-angle lens very powerful because the photographer can choose a small object like a rock or a flower to make it look bigger than anything else in the scene.  

To reduce the amount of space taken up by the sky, tilt the camera downward to accentuate the foreground area.  

Using a tripod is the wrong way to shoot an ultra-wide lens.  For all of the points mentioned above, shooting at dawn or dusk of the day, or narrowing the aperture to F /11, meant using a tripod.  Combined with the need for manual focus, we were back in the days of traditional photography — carefully composing before each shot, setting up the camera according to the rules, and then carefully taking the next shot.  This is fine for landscape and architectural photography, but not so good for portraits, sports, or street photography.  

For architectural photography, contrast is more important than resolution, and the other important thing is to find the “convergence” of all the lines and focus on them.  

Wide-angle lenses are not suitable for portraits unless you want a cartoon-like comic effect.  Shot at extremely close range, objects close to the camera are exaggerated, such as the nose and forehead.  But for ambient portraits, super-wide lenses can be useful, in a shop, office or studio, to show the environment in which the person lives and works.  

Ultra-wide angle lenses are great for telling stories, adding drama to the picture, and making it more expressive.  It can show us things we’ve never seen before.
