What is HDR (High dynamic range imaging) in Photography?
High Dynamic Range Imaging (HDRI) is a set of processes that allows a greater dynamic range of exposures than normal digital imaging techniques. The purpose of HDRI is to precisely represent the wide array of intensity levels found in real life scenes ranging from direct sunlight to dull shadows.
This process was developed to produce a high dynamic range image from a set of photographs taken with a range of exposures. Information stored in high dynamic range images usually equates to the physical values of luminance or radiance that can be observed in the real world. This is different from traditional digital images, which represent colors that should appear on a computer monitor or a printout.

What Is Cable Release In Digital Photography?
Cable Releases are the gadgets attached to Digital Cameras that let photographers shoot photos from a distance. Cable Releases are generally attached to a camera on a tripod. Cable release consists of a wire which extends from the camera and has a button trigger at the end of it. The photographer holds the button end of the cable and presses to trigger the camera shutter to take a photo.
Cable releases, along with tripods, are best used for film that need extended light exposure. In these cases, the camera’s shutter must stay open longer, causing the photographer to remain steady and steady for a lengthier period of time. Therefore, when the photographer wants to eliminate the possibility of the camera shaking, he/she should use a tripod and a cable release.
What is Tack Sharp photography?
Tack sharp is the term professional digital photographers use to describe the ultimate level of sharpness.
One of the best ways to take Tack Sharp pictures is to use a tripod. The tripod keeps the camera steady and still and the digital camera can now focus on (pun intended) to a quality picture.
