Good photographers should always be willing to record a unique moment, we know that the best and most interesting photographs are made from unique and fast moments, there is nothing like a spontaneous moment in a fraternization, an attack of an animal, a decisive gesture in a football match?These are all situations that won’t wait for the photographer to be ready to record them, so every second makes all the difference. One of the things that can annoy the photographer when recording the decisive moment is the “shutter delay” or “shutter delay”, which is just the time between shooting the camera and the moment the computer photographs and captures the camera. . Unfortunately, on some photographic equipment it is not possible to avoid this delay, they cannot change the shutter speed, but there are some tricks that can be followed to minimize the negative consequences and this is what we will see in this article.
Henri Cartier-Bresson was a French photographer and, to this day, he is known to be one of the best in the history of photography. Cartier-Bresson has written some books on photography and one of his favorite subjects was the defining moment, that is, a unique moment captured by the keen eye of a photographer. A moment that only takes a few seconds and if the photographer is not always prepared, he can get lost. Moving images? (translated to? The decisive moment?) was a work dedicated specifically to this topic. In the book, published in 1952, Cartier-Bresson argues that this moment still exists in photography and that it is up to the photographer, according to his experience and intuition, to know how to define it and choose the best moment to photograph. the camera. . An example of this is one of the most famous phrases in this book: “Whoops! The moment! Once you lose it, are you lost forever? The problem is being able to record this unique moment with the shutter lag. How do you capture the decisive moment if when you pull the trigger it still takes a long time to take the picture? Before we know how to mitigate the effects of delayed formwork, let’s learn the reasons why this happens.
- Focusing is one of the main causes of shutter lag in compact digital cameras.
- When the photographer presses the shutter.
- Before the shutter makes the closing and opening movements that capture the image.
- The equipment focuses on the elements of the scene and this accentuates the Y because each scene is different from each other.
- The focus must be done every time you take the camera.
Fortunately, the shutter offset in case of an approach can be corrected. Focus can be done and adjusted by pressing the shutter mid-run, without taking the photo. Therefore, focus first on the scene and when your compact camera tells you it is sharp. , tap the rest of the shutter to take the picture. The shutter time will be significantly reduced if these measures are taken.
Shutter delay also exists in DSLR cameras, but they are smaller than in compact cameras, as professional equipment is already manufactured to achieve faster image results. In dSLR, for example, the main cause of shutter delay is the mirror that reflects the preview. image. As it must be lifted for the light to reach the sensor, the equipment will take longer to fire the camera. This delay is very short, but may vary by camera. In this case, there is also a delay for the photo. , but this time is much shorter than in compact cameras. The photographer can reduce this delay as mentioned above, or by using manual focus.
Another type of delay the photographer may encounter in DSLRs is the time it takes for the sensor to process the image. This delay is not considered a shutter delay because it occurs after the camera is taken, but this delay can interfere, for example, with sequential capture of multiple photos, as the camera can spend a few seconds processing each photo. To avoid this delay in DSLRs, simply pull the trigger several times in a row and let the sensor do the work after completing the entire sequence. It should be remembered that the time to process the images in this way will be much longer after several camera shots. For compact cameras, there is the continuous shooting option that, on most computers, allows the photographer to take up to five photos. before the sensor starts processing the images. To find out if this feature exists on your camera, simply read the manual and find out how it works.
