Getting to know your digital camera

Surely every reader of the magazine who has a camera, upon seeing a beautiful flower, an unusual composition or a spectacular bouquet, could not restrain the desire to capture them as a keepsake. However, the picture was disappointing because it didn’t look the way I wanted.

Why? Or your hand trembled when you pressed the shutter button, or the frame came out too light, or, conversely, too dark and unclear. In order to get only good pictures, you need to master basic skills in using a camera and follow the basic rules, which we will gradually reveal in our articles.

Cameras can be divided into two classes. DSLRs with interchangeable lenses are large, heavy cameras with many capabilities, and compact point-and-shoot cameras that are easy to use, lightweight, but limited in shooting parameters, since their lens cannot be changed.

Any camera is designed the same: body, lens, viewfinder, shutter, aperture, matrix, built-in or external flash and controls – levers, buttons, wheels. We pick up the camera to take a photo. Have you noticed that if you hold the camera for a long time, your hands begin to tremble a little from tension and when we press the shutter button, the frame turns out “blurred”?

To prevent this from happening, it is better to install the camera on a tripod, and if you don’t have one, lean your elbow on some kind of support.

The photographs show a clear example of a normal and “blurred” frame

And here we have a flower arrangement. We must convey her image in the photograph as accurately as possible. In order for the photo to be natural, not too dark or overexposed, you need to set the exposure correctly.

Exposure
– this is the ratio of shutter speed (the time during which light hits the photosensitive element – the matrix) and the degree of opening of the aperture. By adjusting the amount of light, you can get an image with the maximum amount of detail and halftones.

Aperture
– this is a device that limits the beam of light passing through the lens and regulates the depth of field and sensitivity of the matrix.

All photos show the same flower arrangement. The top photo clearly shows a good, high-quality frame. The middle one illustrates underexposed and the last one illustrates overexposed frames.

We see a flower arrangement that is too light. In other words, details have disappeared on its light parts. Why did this happen? Because the camera perceives any object as, so to speak, medium gray. In order for light objects to remain light in the image, and dark objects to remain dark, you need to make exposure compensation – add or decrease the amount of light falling on the matrix compared to how the camera measured it. To do this, most cameras have a special button and a wheel with “+” and “-” marks and divisions showing by what amount the exposure can be changed.

If your camera does not have such a function, you can do exposure compensation yourself. To do this, you need to point the camera at some gray object located at the same distance from the camera as the composition. Next, you need to press the shutter button halfway and, without releasing it, point the lens at the subject you are shooting and press the shutter button all the way.

In order for the picture to be not only correctly exposed, but also of the best quality, bright, with all the details, you need to use a low sensitivity of the matrix, as mentioned above. You need to remember this characteristic of the matrix, since the lower the sensitivity, the higher the image quality. The sensitivity of the matrix is ​​set in the camera menu and is indicated by the letters ISO. It has values ​​from 50 to 3200. For modern SLR cameras, the optimal sensitivity can be considered 200-400 ISO, for compact cameras – 100-200 ISO.

Here are a few simple rules that will help you take good pictures as a souvenir. And in the next article we will talk about how to correctly build perspective, avoid “noise”, distortion and other problems.
