Some scenes look better when the sun went down, but taking pictures in low light conditions is much more complicated than in the afternoon. It is obvious that the whole picture is associated with light, and only in the light we can get the image.
Therefore, when the illumination level decreases, it becomes difficult to remove. In these conditions it is necessary to postpone or camera, or to change the approach.
There are three options for shooting in low light. We can open the valve to allow delivery of more light, while it will be necessary to use a tripod or alternatively more open the aperture, or increased sensitivity to shoot handheld.
Finally, we can further illuminate the scene of internal or external flash. These options are different, and each has its pros and cons. But all three options allow you to shoot when the sun went down. Tripod and long exposure One way to allow more light to the matrix – the shutter open for a long time.
Under low light, the shutter speed should be 1/15 sec or longer. With such exposure can not be removed from the hands due to camera shake, so its stability needed a tripod or something like that. If the subject is mobile, that too will cause blur.
So, the approach with a slow shutter speed is not suitable for scenes with motion, such as concerts. This embodiment is advantageous shooting when the most important thing – to get high quality images. Lengthening the shutter speed, you can shoot a low light sensitivity, and digital noise will be small.
So shoot architecture and landscapes. High sensitivity, opening the aperture When the shutter speeds are not suitable, as it can be, if necessary, to remove from the hands or fast-moving subject, the have to look for another option.
One of the ways – increasing sensitivity. Most cameras lowest sensitivity begins with 100 or 200 ISO. For these values of the highest image quality. With increasing sensitivity, you can use faster shutter speeds, but the image quality will suffer because of the digital noise.
So convenient compromise between not too high sensitivity and aperture lenses with aperture of f / 2,8 or more. The more light you skip through the aperture, the lower sensitivity can be applied to still shoot with it and “freeze” movement in the image.
Shooting with a high sensitivity and a large aperture – ideal for shooting at concerts and the theater, and in addition, at parties and on the street at night. The advantage of this option, pre-flash is that you can still use natural light, which can make your photos more expressive.
Shooting with flash Flash – a versatile tool. Everyone who uses a compact camera, familiar with this, but probably not always happy with the result. Firstly, a frontal light creates harsh shadows, reflections, and other rude bad moments, such as red eye.
Second, the normal flash replaces the existing lighting, and it can be used to enhance the expressiveness picture. This does not mean that the flash is not needed, but we should be able to manage it in order to overcome these shortcomings.
Directing light standalone flash, we decide where shadows will fall and how to avoid reflections. If the shutter open for a long time with flash – then catch another and external lighting, which can give a snapshot view of a more expressive.
