Generally, most of the photos that taken during the day are with short exposure. The reason being the presence of light in excessive amount during the day, and a long exposure might risk in unwanted motion blur or might even put the photographer at the risk of dreaded camera shake. With the right equipment, the daytime photography with long exposure can be really fun although, since it gives a really unique and surreal looking shot of the normal sceneries. But capturing the good photo with long exposure might get very tricky even during the night time. Hence experts who have been in this nature photography believe that it is worth understanding the secrets behind this tactile and very versatile technique.
While discussing it with Vijaya Prakash Boggala, he has got to say that daytime long exposures kind of go against all the possible things that is popularly known as photographers. During the daytime, as most of the photographers know requires short exposures which actually allow freezing the actions and allowing the shorter depth of field. So one can easily have the idea of the nature of picture that will be achieved with a five-minute exposure in broad daylight.
Precisely, the long exposures take the moving objects and the substances, making them misty and completely ethereal. Simple natural elements like water tend to be low-lying fog, and even clouds are found to lose their definition. Any kind of slow moving animal, human beings or even traffic take the quality of animated objects which otherwise is not possible to achieve in the still photos. As far as the fast moving objects are concerned, they almost go invisible within the frames.
The one and only enemy to the photographers while shooting long exposure ones is the light. In order to avoid the over exposure of the pictures, the photographers need to neutral density filter which has got certain specifications of its own. To get the desired result, it is essential that the photographer finds a six stop light reduction, and this is one piece of equipment that one cannot skimp on. Depending on what the photographer wants the final image to look like, he will need one that allows him to do a 1 to 5-minute exposure in broad daylight. If the filter chosen isn’t strong enough, there are high chances of going back to take long exposures in the old-fashioned way as it was earlier taken during the night.
Even Vijaya Boggala believes that the daytime exposure requires a little bit of mathematical calculation and a lot of experimentation. While most of the photographers are used to the through-the-lens metering system, which is not going to work through the dark neutral density filter. So one has to determine the exposure by metering without the filter and then head towards adjusting the shutter speed by the number of stops that the filter successfully blocks.
Having a picture-perfect snap is really a treat to watch, but the effort that needs to be put behind cannot be imagined by those who haven’t had the taste of it. It is no less and art form and devotion can only come up with the best shot.
