Things look very different to us in a picture than they do in person. This is mostly due to our ability to perceived depth. Most of the tricks our brains use to perceive depth are removed when looking at a photo. This makes us appear fatter because we cannot completely discern the curved edges of the body.
Do I need a 35mm and 50mm lens?
What’s more, if you’ll be working in tight spaces, or conversely, want the ability to capture more of the scene in a single shot and have more of the background in focus, the 35mm is the way to go. On the other hand, if you want greater reach regarding focal length, a 50mm lens will serve you better.

As good as 50mm lenses are, 85mm lenses have their own set of advantages for portrait photography. … Furthermore, 85mm is a great focal length for portraits because it’s in the short telephoto range, which means that you can stand further away from the subject and still get nice close-up shots.

WHAT IS lens in human eye?
The lens is located in the eye. By changing its shape, the lens changes the focal distance of the eye. In other words, it focuses the light rays that pass through it (and onto the retina) in order to create clear images of objects that are positioned at various distances.
How do glasses use waves?
When a light wave moves from one medium (like air) to another medium (like glass) the light rays are bent. This is called refraction. By using refraction, lenses can bend multiple light rays.
What lens do I need for long distance?
Telephoto and Superzoom Lenses If you need a camera lens for far away shots, you need a telephoto or superzoom lens. Telephoto lenses have a fixed focal length starting at around 70mm. Superzooms—as the name implies—are zoom lenses that cover a range of focal lengths.
Why do I look so much fatter in pictures?
A wide angle lens does as its name suggests, capturing an image spread over a wide angle. The field of view in a wide-angle shot is wide—wider than that of your own eyes. In pulling this off, some lenses create a sort of fisheye effect, which can bloat subjects in the middle, and stretch those on the outside.
Is 18mm a wide angle lens?
The angle of view of a lens of a particular focal length is dependent on the size of the imaging medium. On on a 35mm sensor or film (full-frame sensor, such as what you get with a Canon 1D or 5D, the Nikon D3’s), an 18mm DSLR lens is a wide-angle lens.
Is a bigger lens better?
For both amateur and professional photographers, it’s generally acknowledged that lenses are more important to craft than the actual camera body. … Not all lenses fit every situation, and though it may feel counterintuitive, bigger isn’t necessarily better.
What are the 2 types of lenses?
The two most common types of lenses are concave and convex lenses, which are illustrated below in Figure 1. A common bi-convex lens is considered a positive lens because it causes light rays to converge, or concentrate, to form a real image.
What does the size of a lens mean?
Focal length, usually represented in millimeters (mm), is the basic description of a photographic lens. … The longer the focal length, the narrower the angle of view and the higher the magnification. The shorter the focal length, the wider the angle of view and the lower the magnification.
Where are lens used?
A lens has the valuable property of forming images of objects situated in front of it. Single lenses are used in eyeglasses, contact lenses, pocket magnifiers, projection condensers, signal lights, viewfinders, and on simple box cameras.
What is the first lens you should buy?
We recommend starting with the Canon EF 70-200mm f/4L as your telephoto and, if you have an APS-C body, the Canon EF-S 10-18mm f/4.5-5.6 for a wide-angle option. If macro is your thing, start with the Tamron AF 90mm f/2.8 Di SP. Or for a kit lens upgrade for APS-C bodies, go with the Sigma 18-35mm f/1.8 DC HSM.
