Now that the holidays are over, it's a good time to develop the photographs you've taken during your travels. Moreover, so that your next shots are even more successful, we give you three essential tips to achieve a beautiful photo!

Shutter speed

Located between the lens and sensor of any modern camera, the shutter is a mechanical system that controls the entry of light into your lens. Expressed in seconds and fractions of seconds, shutter speed is the length of time light reaches the sensor. It allows either to freeze the action completely, or on the contrary to transcribe the movements, thus allowing to give a feeling of speed to the shots. The longer the exposure time, the more time the light has to pass to the lens. How to take a beautiful photograph in three steps? Depending on the shutter speed, the user should also use their diaphragm to let in light or not to avoid overexposure or underexposure. The shutter speed therefore has a direct impact on the aperture of your camera's iris . The shorter the shutter speed, the larger the aperture of the diaphragm, resulting in a shallow depth of field. Conversely, the smaller the aperture, the higher the area of sharpness.  

The opening of the diaphragm

The diaphragm is a mechanism inside the lens through which light passes through and is redirected to the camera sensor. This one is simply the eye of your device. The iris has the same effect as the iris, it allows the image to adapt to the brightness of the place where you are. You can reduce or enlarge the size of your iris aperture to allow more or less light to reach the camera sensor. How to take a beautiful photograph in three steps? The larger the aperture (the smallest number), the more light passes through and vice versa. Thus, a small iris aperture increases the depth of field and the area of sharpness. Conversely, a small aperture makes it possible to obtain a blurred background, often used in the realization of a portrait.

ISO sensitivity

ISO is the unit of measurement for controlling the sensitivity of digital sensors to light. It is simply the amplifier of the digital signal generated on the sensor. Typically, on modern cameras, ISO sensitivity ranges from 50 ISOS to 51,200 ISOS. The higher the ISO sensitivity, the more sensitive the camera will be to light and vice versa. However, increasing ISO sensitivity can have a negative effect on image quality. It brings out "digital noise", which results in a sheepfold of unsightly colors on the image. Basically, the more this "noise" is present, the finer the details of the photograph. The brighter the place where you take your shot, the lower the ISOs. unnamed How to take a beautiful photograph in three steps? But when the sunlight decreases, with gray weather or a poorly lit room the user is forced to increase his ISO. Switching from one ISO sensitivity to another will change the iris aperture and shutter speed. The ISO button located on your device allows you to change the value of said ISO, which adapts according to the light, while being as low as possible. This is how to succeed in your photographs via these three small steps. Obviously, it 's a little more complex in practice than a theory, and many details make it possible to improve his shots. Each of these steps requires some preparation beforehand, before taking a photograph. It is by playing with these three phenomena that professional photographers take their shots. Of course, all this can also be managed by the automatic modes of the cameras. But it's still less interesting, isn't it?
