Digital Camera Know-Hows

The many types of cameras has given ascent to a wide variety of viewfinders. Among optical viewfinders is the existent-epitome viewfinder, which uses a divide lens just for viewing, and the SLR-type viewfinder that uses the photographic camera'due south lens to allow directly confirmation of the image. Some digital cameras apply an LCD viewfinder to view the images captured past the CCD, while others utilise a larger LCD monitor, or both. Each type has its advantages and the efficient use of both is the mark of a skillful lensman.

Viewfinder Types and Characteristics

A broad variety of viewfinders be, each with its own strengths and weaknesses.

Method	Optical Real-Epitome Viewfinder	Optical SLR Viewfinder
Construction
Feature	Photographic lens and viewfinder lens are separate.	Image passes through the photographic lens and is reflected via a mirror or prism into the viewfinder.
Reward	Moving subjects are easy to rail. Consumes no electricity.	Able to view and confirm the bodily image that volition be recorded to movie. Moving subjects are easy to track. No parallax. Can use high-powered zoom lenses. Consumes no electricity.
Disadvantage	Parallax occurs when subjects are too shut to the camera. Cannot exist used with high-powered zoom lenses.	At the instant the photograph is taken, the flipping up of the mirror creates an image blackout.

What is Parallax ?

With a lens-shutter camera, parallax is the difference betwixt what the viewfinder sees and what the camera records, particularly at close distances. This is acquired by the separation between the viewfinder and the picture-taking lens.

Method	Electronic LCD Viewfinder (EVF)	Electronic LCD Monitor
Structure
Feature	The image that passes through the lens and is processed by the CCD is displayed on the EVF as digital data.	The image that passes through the lens and is processed by the CCD is displayed on the LCD monitor every bit digital data.
Advantage	Able to direct view the paradigm recorded on the CCD. Viewfinder coverage is high, without parallax. Tin can be used with high-powered zoom lenses. Like shooting fish in a barrel to view, even outdoors at midday.	Able to run across on a large screen the bodily paradigm recorded onto the CCD. The appearance of the image is shut to the bodily photo, making composition easy. Viewfinder coverage is loftier, without parallax. Can be used with high-powered zoom lenses.
Disadvantage	Consumes electricity, though the corporeality is pocket-size.	Hard to view outdoors nether bright conditions. Power consumption is loftier. Since viewing the monitor causes the elbow to be bent slightly outward when the picture show is taken, hand-milkshake tin easily occur.

What is viewfinder coverage?		What is viewfinder magnification?
This indicates the percentage of the bodily image recorded on the moving picture or CCD that can be seen in the viewfinder.		This effigy represents the ratio of the size of the actual image seen by the naked eye to the size of the image seen in the viewfinder.
	The wider the viewfinder coverage, the easier it is for the photographer to visualize the trimming amount. For example, if the viewfinder coverage is 80%, the remaining twenty% will be cut off.		If the size of the image seen by the naked eye and the size seen in the viewfinder are the aforementioned, the viewfinder magnification is said to be 1x. The higher the magnification, the easier information technology is to bank check the focus and other items. *Viewfinder magnification is measured using a 50mm lens.
