Hyperfocal Focusing: What Is It And Why Should You Use It?

When should you use hyperfocal focusing? Well, sometimes when shooting a landscape, you want everything sharp from the front to the back of the scene. Setting a small aperture such as f/16, f/22 or even f/32 can help, but if you really want to maximize depth of field, hyperfocal focusing is the technique you need to use.

Exposure Compensation

The digital camera is in reality a great possession with many facets of its utilities and not only that knowing these utilities makes the understanding the digital camera complete. The utilities are also so very diverse that they too offer further introspection of details in their varying applications. Such an area is digital camera exposure compensation. Only knowledge of digital camera exposure is not enough, so the digital camera exposure compensation requires some amount of exposure in itself! This discussion is focused towards that cause itself.

Camera Filters - How They Work

The purpose of filters in a camera is fundamentally the same as filters in other tools: trapping dirt or large, undesirable particles. Camera filters, though, help to produce many desirable effects and enhanced looks in photographs.

Buying Or Cleaning a Used Camera Lens? 5 Reality Checks You Can Do

There are useful checks you can make before you lay out your hard-earned cash on a lemon, or to use on your own lens before shooting. Lens faults will degrade the image you are so carefully trying to make. No matter how much you spend on a camera, if the lens is deficient or inferior there is nothing you can do to rescue the shot once it is made. Eyeballing these pointers is a good way to keep the technical quality up. 

The Importance Of Investing in A Dry Cabinet

If you are having trouble protecting your MSD (moisture sensitive devices) from humidity related damages, you are on the right page. In this article, we are going to shed some lights on the importance of electronic dry cabinets. Basically, a dry cabinet is an enclosure that can keep electronic components from getting exposed to excessive moisture environment. People use these when they need to put their moisture sensitive products into low humidity environment. We know that excessive moisture can damage specific products, such as PCB, IC, chips, optical products, precision instruments. Since moisture can have a negative impact on the device performance and cause malfunction in some cases, it's important to keep them in a place where these problems won't occur. Without further ado, let's find out why you may want to invest in a dry cabinet to meet your needs.

Characteristics of Camera Lens

-Focal length: Light rays which are parallel to the axis of the lens, after passing through a convex lens meet at a point on the other side of the lens. This point is called as a focus of the lens. The distance between focus and the optical centre (or node) of the lens is called as focal length of that lens. Focal length of a camera lens may also be defined as the minimum practicable distance between film/image sensor and (the optical centre of) the lens. Focal length of a camera lens is usually marked in mm on the front of the lens. Focal length remains fixed for a given lens (other than zoom lens). SLR camera may take lenses having different focal lengths.

Different Kinds of Camera Lenses

Normal:- A normal lens shows most accurately what a normal human eye will see. 50mm is a typical normal focal length. The 50mm is the most popular and versatile lens. The quality is excellent while also being inexpensive. It is smaller and lighter, and the aperture allows photographs to be taken in low-light situations.

Telephoto:- A telephone lens brings the background closer. Longer-than-normal focal lengths such as 70mm and 300mm are typical for a telephoto lens. Since a telephoto lens will bring the subject up close, it is popular for sports photography.

Wide Angle:- A wide lens captures a wider expanse of the background than what the human eye will see. Shorter-than-normal focal lengths such as 24mm and 35 mm are typical for a wide lens. Wide lenses are popular for landscape photography and large group shots.

Other special lenses to consider include the following:-
Macro:- A macro lens's focus is closer to the subject and is used for close-up photography.

Fish-eye:- A fisheye lens uses an angle of view up to 180 degrees. The angle distorts the photograph so the four sides appear to be farther away.

Teleconverter:- A teleconverter attaches between the camera and another lens. It increases the focal length of your lens. Although teleconverters will bring the subject closer, they do not allow as much light through the lens. Thus, they need slower shutter speeds and/or a fast ISO.
