About aperture

Before we jump to how to change the aperture ion Nikon D3100, the first thing you should understand is what “aperture” is. Aperture is a circular hole that allows the light to pass through it, through this circular hole the light touches the sensor.

The smaller the hole the less amount of light will be able to pass through it; this is how it helps you in creating dark images. The aperture of the camera performs in f-Stops.

For instance, if you want to capture photography with a nice touch of a blur then you can use focal length –stop of 3.5mm, but if you are shooting a landscape scenery then obviously you will have to capture a shot that focuses on every spot of the picture so for that you will need a focal length of 11 or 12.

Aperture settings on manual mode

Back then when the camera comes with program modes, the camera comes with manual modes. As that camera has only one mode so it wasn’t named “manual mode.” The truth is that most photographers have to cut their teeth to master the art of photography when everything was in manual mode.

The photographers who wanted to learn the skills of exposure, shutter speeds, ISO, and aperture, the best way for them to learn these skills is by adjusting the setting by themselves.

But nowadays, things have been completely changed, the automatic mode does the job so perfectly that photographer doesn’t give a thought to use the manual mode. No doubt, the manual mode is the best mode to learn the basics of photography.

When your camera is set to manual mode, the camera gives you every reading of which mode and scene you are shooting in. You are allowed to set the f-stop aperture and the shutter speed of the camera so that you can get the shot of perfect exposure.

Automatic mode means that you don’t have to worry about these settings like aperture adjustments, IOS, and shutter speed adjustment, but in manual mode, you have to set everything by yourself.

The learning of working of IOS, aperture, and shutter speed can be a little confusing and challenging but once you have learned how it works, you are all turned in to get the best creative shot.
