Distance and other digital cameras functions

We know what the photographer will have control digital cameras, light, and exposition. The art of photography is magnificent. If one of these elements fails or there is no picture. Moreover, cameras can be classified as a function of many things: the medium in which images are stored (analog or digital), the size of the sensor or film size (compact, bridge, DSLR) or in the degree of automation (this rather in the analog era there were cameras in the camera manual and automatic).

It is not about exposing a manifesto about the different types of digital cameras but basically explain the types that exist to help the amateur understand the differences between them. We can distinguish between digital basically the following types, which differ mainly by their size, the size of the sensor and its features. You can opt for:

-         Compact

-         Intermediate

-         SLR

When focusing on distance, the Hyperfocal distance is the distance of approach that achieved the greatest depth of field, extending it from half that distance to infinity. Focus on this distance will help us to achieve maximum sharpness in your photos, such as landscapes.

In the following example, the hyperfocal distance that allowed us to achieve maximum well depth of field and sharper drop everything possible was 6 meters. So we are moving to 6 meters of the subject, focus and get the maximum depth of field, which extends from the middle distance, 3 meters to infinity.

Are you familiar with distance aspects? The hyperfocal distance depends on the focal length of our lens, the aperture used and the sensor crop factor of the digital cameras. This will vary depending on the zoom we apply, the f-number set and model of your camera. Obviously we're not going to take pictures with a meter and when we will apply this approximate. With digital cameras you can also help a lot the field preview button, which allows the viewer to preview depth of field we will have with the current settings of the camera.

In the next photo I used a 17mm focal length in a chamber with a conversion factor of 1.6 and an aperture of f/10. The hyperfocal digital cameras distance with these data is 1.5 meters. Stand close and focus on the image so it will be completely clear, from 0.75 meters to infinity. Thus we see how both the foreground and snow across the road to the horizon is completely sharp.
