Low-light situations impact your signal-to-noise ratio, thus introducing noise in your image. The signal here refers to the actual information, data that you will be capturing.  In order to get the best image quality, the idea is to capture enough signal in order to overpower the backdrop of noise. To compensate for low lighting, photographers may use high ISO setting, a longer shutter speed or setting a wider aperture. 

When shooting a scene, each pixel emits a signal when it meets with light. When shooting in low-light condition, pixels have little light fluctuation to report but are being amplified by high ISO settings. At high ISO the camera’s sensor becomes more responsive to light. The higher the ISO, the brighter the resulting shot. There is nevertheless a trade-off: by increasing the ISO, more noise will be added to the final image. It is important to note that ISO settings have no creative impact on your photography, unlike aperture and shutter speed.

Think of the aperture of your camera as the pupils of your eyes. Pupils adjust to the amount of light. They open up in low light environments and dilate in dark environments to let in more light. While ISO determines how fast light reaches your camera’s sensor, the aperture determines how much light it lets in. A smaller aperture allows less light in but increases the depth of field. A wider aperture lets more light into your camera but decreases the depth of field. That can cause your image to be out of focus.

Another determinant factor is your shutter speed, that is to say how long your sensor is exposed. A longer exposure time, e.g a slow shutter speed, will allow more light in. Shutter speed can compensate for images that appear too bright or too dark at the aperture you set. However, if you are shooting using slow shutter speed, it is essential to keep your camera still or to use a tripod in order to get crisp and sharp images. Otherwise, any sort of movement in your scene will result in ghosting effects, or blurry images.

HDRinstant lets you overcome traditional constraints. 

What does it work? Well, it’s very simple:

• You film your scene
• You select the best moment of your video 
• HDRinstant processes that frame and does its magic! 
• Your photo is enhanced and the noise present on the original frame dramatically reduced. Based on a stacking technology, that piece of software uses multiple frames of your video sequence to fine-tune the details of very dark or bright areas, thus increasing the Signal-to-Noise Ratio.
