For sure many of you enjoy daily the photos of Sri Parthasarathi and other Emperuman during purappadu at Thiruvallikkeni. Over the recent decade or so, there are so many good photographers painstakingly taking pictures and superb angles and sharing them on social media
No post on ordinary people but legends who give quality output to the happiness of many devotees. Photography is no art or Science, complex not simple. There are many aspects to be mastered – it is not simply holding a Camera, lifting hand and shooting !
Of the many technical aspects there is - Focal length, usually represented in millimeters (mm), is the basic description of a photographic lens. It is not a measurement of the actual length of a lens, but a calculation of an optical distance from the point where light rays converge to form a sharp image of an object to the digital sensor or 35mm film at the focal plane in the camera. The focal length of a lens is determined when the lens is focused at infinity.
Lens focal length tells us the angle of view—how much of the scene will be captured—and the magnification—how large individual elements will be. The longer the focal length, the narrower the angle of view and the higher the magnification. The shorter the focal length, the wider the angle of view and the lower the magnification.
Lighting is most important be it broad day light or night !! ISO Sensitivity is a standard set by the International Organization for Standardization (ISO) that represents sensitivity to light as a numerical value. A higher number indicates a higher sensitivity and a greater ability to capture light. The ISO Sensitivity is set and changed in the shooting settings menu. If the ISO Sensitivity is doubled, the amount of light reaching the image sensor required for a suitable exposure is halved. For example, if the ISO Sensitivity is increased by one stop from ISO 100 to ISO 200, you can shoot with the shutter speed one stop faster or with the aperture value one stop narrower.
You can ignore all that is described but cannot ignore these legends – MAPs (MA Parthasarati) explaining the nuances to video king Krishnavaibhavam Kanakarajkumar with Raghavan Nemili Vijayaragavachar and Mandayam Murali Krishna seen in the background.
