In the exposure mode, you can manually set the shutter speed, while the aperture value is set automatically according to the brightness of the subject. A high shutter speed lets you resume the movement of a rapidly moving subject. With a slow shutter speed, the subject will appear blurry to give the impression of movement.
Think about it, how often do you take photos at a party, at a wedding (or other ceremonies), in the theater, while you’re out at night? How many of these photos are moved, severely underexposed, excessively grainy (because of the noise)? Fortunately, there are some tricks that can save us on these occasions, some valid for any digital camera, others only for reflexes linked to Wedding Films.
First of all, watch the exposure triangle. Our goal is to get the camera as much light as possible, since there is little. To do this, the three parameters of the exposure triangle must be configured as follows: the opening must be low (ie it must be wider), the ISO must be high and the exposure time must be long to ensure quality Wedding Films.
Obviously, the three values cannot be raised and lowered indiscriminately, because every change has consequences on the final aspect of the photo (to know which lowering the opening decreases the depth of field , raising the ISO increases noise, a too slow exposure time causes blurry photos.
Let’s say that, on many occasions, you can trust to use the lowest aperture value offered by the camera and the lens you are using. For the exposure time, better not to go below 1/60s, in general. In more particular cases, when the framed Wedding Films subjects move quickly, you will have to use shorter times (therefore with smaller values).
The speech of ISO becomes more delicate. The most common cameras, that is all the compact cameras and the bridges as well as the cheapest cameras, have excellent performance for the highest ISO values. This means that, going up to ISO values that could be very useful when the light gets really poor, the noise introduced in the photos becomes easily unacceptable. For example, my Nikon D3000, with ISO values above 800, often makes photos unwatchable (although it could reach 3200 for Wedding Films).
If possible, it is better to know the value of ISO than not to go, peculiar to each camera. Trying to take several photos for each available value, it is easy to understand the limit beyond which not to go. However, when it becomes necessary to use excessively high values, you can still count on the removal of the noise that can be made through the photo editing programs.
