In the human eye, however, the cones are concentrated at the centre of the retina. When the mirror reaches the horizontal position it fires a focal plane shutter just in front of the film to make an exposure. However, transmissive LCDs are much more limited in terms of what can be superimposed practically, because they can basically only darken, not lighten the image. Digital single-lens reflex cameras, or DSLRs, are a type of camera that has been gaining in popularity in recent years. But they front a steeper learning curve if youre a beginner.

From high-school physics: there are three types of things we call "lenses": simple lenses, compound lenses, and complex lenses. What's the advantage of a DSLR's "previewer" viewfinder, since I have observed that mirrorless cameras appear to have the same thing? What's the difference between "exposure level indicator" and "exposure setting meter" in the Canon EOS 1DX Mark II viewfinder? SLR DISADVANTAGES - You cannot see through the viewfinder while the exposure is taking place. They are "reflex" because you view through a mirror which reflects the subject. Because of the inability to adjust focus, the small lens aperture and the low sensitivity of the sensitive materials available, these cameras work best in brightly lit day-lit scenes when the subject is within the hyperfocal distance for the lens and of subjects that move little during the exposure. For this reason, many users end up resorting to the use of adapters that allow using the lenses of other systems, such as the Canon EF mount.
