How to make a good photo if you do not have a professional photographer

Buying a digital camera is for many nightmares. What kind of camera to take, how many megapixels, how big is it, how much to spend …? Through this guide we will try to explain the basic features of the camera, and in the second chapter that will follow in ten days to point to some of the best models we have personally tested.

1. SENSOR
The number of megapixels is completely unimpressive. Indeed, a smaller number of megapixels is often a better solution. Even when the cameras had 4 to 5 megapixels, it was quite enough for viewing images on a computer or developing them up to A4 format. Today, it’s almost impossible to find a camera with less than 8 megapixels so you do not have to worry about whether the photo will be large enough.

When too many pixels are placed on the same surface of the sensor, many negative consequences arise, such as an increase in digital noise, extremely ugly artifacts resulting in forest noise reduction, dynamic range reduction, and poor color reproduction. This is particularly true for compact and ultrasound devices that use small sensors of a few millimeters per page.

2. OBJECTIVES
Most people as the crucial feature of the lens are looking at the amount of built-in or external lens, which is a bad approach. Zoom in 3x, 5x, 10x, etc. does not actually mean zooming but the range between the minimum and maximum focal length of the lens. Lens focal length is exactly what attention needs to be paid to. For example, a 10x zoom lens can have a focal length of 38-380mm, but it can also be 24-240mm. In this case, the latter has a significantly wider viewing angle and is most often a better choice for most users since “catches” are widespread, which means lots of landscapes or group photos of people.

3. STABILIZATION
Stabilization is one of those things that are not necessary, but under certain shooting conditions make a huge difference. To make the image crashing, the camera needs to be completely motionless during recording. Unfortunately, when we hold it in his hand, he always shakes as much as he or she is concerned with what is a special problem for longer exposures or at large focal lengths. This is due to stabilization. There are two types; Stabilization with a moving optical element in the lens and the motion sensor. The principle of work is simple. When the entire appliance in your hands is moved in one direction, the stabilization moves the lens or sensor in the opposite direction by compensating for this shift and ensures a sharp image.

If you are frequently recording in conditions with less available light (dusk, night, indoor areas, etc.), we strongly recommend the stabilizer.

4. WHITE BALANS (WB – WHITE BALANCE)
The white balance is one of the most important settings for taking pictures. The appliance does not know for itself what colors should look like and it is necessary to adjust the “color” of the light. Every source of light (sun, neon lights, halogen bulbs, candles …) has a different wavelength and therefore different “heat” of the light emitting.
