Why is the camera not in the middle?

The average camera-equipped smartphone has a large, flat battery just behind the back cover. Putting the camera in the middle would require splitting the battery or manufacturing one with a hole in the middle, which would get very expensive.

Why is the lens of a camera circular in shape?

A round camera lens does produce a round image inside the camera. This is because light must be bent more to reach the outer edges of the circular image. To correct for these aberrations and end up with the best image possible, the rectangular sensor crops out the outer edges of the circular image from the lens.

What is the purpose of vignetting?

A vignette is a darker border – sometimes as a blur or a shadow – at the periphery of photos. It can be an intentional effect to highlight certain aspects of the image or as a result of using the wrong settings, equipment or lens when taking a photo.

What is camera lens vignetting?

In photography and optics, vignetting is a reduction of an image’s brightness or saturation toward the periphery compared to the image center. Vignetting is often an unintended and undesired effect caused by camera settings or lens limitations.

Why iPhone camera is on the left side?

Why is the camera on the phone on the right side?

The camera is the thickest component in the phone. Battery takes probably 90\% of the surface of the phone so the camera can not placed on the surface of the battery. So there is no other room left for the camera. However, right top corner is the most appropriate place.

Why are camera lenses round but pictures rectangular?

Lenses are round because that is the easiest shape to grind and polish. Image circles are also round (if they weren’t they wouldn’t be called circles ). Photographs are rectangular because that is the way most people want an image to look so the top, bottom and sides are cropped by the rectangluar shape of the sensor.

Is vignetting is generated by lens hood?

Since lens hoods are carefully crafted for each lens, they are typically not the source of vignetting. Most of the time, mechanical / accessory vignetting is caused by filters, filter holders and other third-party tools.

How do I get rid of vignetting?

To remove vignetting in Lightroom all you need to do is head into the Develop module and under the Lens Corrections panel select the Enable Profile Corrections box. Once this box is checked it will remove the vignette based on a profile based on the camera or lens you used.

Do lens hoods cause vignetting?

Since the wide angle lens has a wider angle of view, part of the scene covered by the lens is cut off by the lens hood and vignetting occurs. In this case, light rays that are not within the angle of view can also reach the lens. This causes lens flare or ghost images, which defeats the purpose of using a lens hood.
