What Happens When You Click
To better understand what aperture is, we must understand how a camera works. Your camera is an apparatus. Light-sensitive materials from the camera then pick it up and save it as a digital picture JPEG, RAW, or on traditional film. As our eye does it functions the same way
Size of the Hole
As you can see, the Aperture of a camera works the same as the iris of your eye. It controls the amount of light the bigger the light, and the hole, the quantity of light comes through. To alter the size of the aperture, change your camera. This is indicated by Av for Canon cameras, or A for Nikon and Sony users. It means your camera goes into semi automatic when you turn into this mode. You choose your camera does the rest.
Based on your Camera, as you turn the dial or push on the buttons that are left-right, notice the f-number changes. This f-number indicates the size.
Note: Largest and the smallest f-number may change based on. It can go from f1 the way.
Have a bit of time to Let this sink as it functions flawlessly on how we think about size and numbers, but it will be second nature to you.
So what does this change of size do?
As it turns out, the Size of the whole aperture impacts.
This amount of focus is called depth of field. When you have the topic in focus and the background blurred out, we have got a depth of roving photographer. It is known as a depth of field, when the background and the subject are in focus.
Exercise: Controlling Length of Field
The best way to learn a concept that is new is by trying it. Grab your camera and put.
- A camera, preferably a dslr
- Eg, your subject. Pencils you have lying about
- Optional: A tripod or mini-tripod that comes free with most purchases
By default your camera will examine the scene and attempt to ascertain where to focus using its clever brain. We will need to alter some settings as we need control over where to concentrate on. We wish to tell the camera where to concentrate, rather let it select for us.
Proceed to your camera Settings, and modify the AF point.
- Set your camera to aperture priority mode, and dial into the smallest amount you can get eg. f3.5
- By half-pressing the shutter button, concentrate on the pencil closest.
- Once it is in concentrated, press down fully to take the picture
- Next this is where the mini-tripod is useful if you have one, raise them. Concentrate on precisely the pen and take the picture.
- Dial to f16 and take your picture.
