As you begin to research cameras, you’ll likely hear some technical jargon about sensors. While it’s easy to ignore some elements of any devices, there’s no way to work around sensors. But what is a sensor and what does it do? In this guide, we’re diving into the often confusing world of imaging sensors. By time we’re done, you’ll have a better understanding of the most significant component in our digital camera.

A lens’s hyperfocal distance—a mathematical combination of lens focal length, aperture or f-stop, and focus distance—is a tool that photographers can use to maximize their depth of field for capturing nearby foregrounds and distant backgrounds in acceptable sharpness.
While you can always dial up your lens’s sharpest aperture (sweet spot), many landscape photographers want as

Depth of field (DOF) is defined as the area in a projected image, forward and aft of the focal plane, which also appears to be in focus in the image. When you pass light through a lens and focus that light to form an image on a piece of film, digital sensor, projection screen, etc., the area of the image that is in true focus is razor thin—the focal plane. Everything else is out of focus, to some degree. However, because of the subtlety of the out-of focus regions, we do not notice the softness of the image until, as objects are located

There is a great deal of confusion surrounding crop factor, and it is particularly difficult to explain, but let’s give it a try, shall we?
Before we dive in, let me dispel two vicious rumors related to crop factor that are circulating through the photography (Internet) world today:
Crop factor does NOT affect a lens’s focal length.
Crop factor does NOT affect a lens’s aperture.
Before you scroll to the bottom of the screen to leave a comment to the contrary, let me explain why I am stating these facts…

So, you just bought your first DSLR camera and you are interested in joining the ranks of image-makers everywhere who find pleasure and creativity in documenting the world as they see it. What are you gonna do now? Do you know how to set your aperture? Or what ISO is? Did you know that DSLR stands for Digital Single Lens Reflex? It doesn’t matter: what you do know is that you’re ready to step up from your point-and-shoot camera and create images over which you have more control.
A digital SLR camera is a great machine that allows you to
