  Shutter speed is one of the three  pillars of photography the other two  being ISO and aperture also known as  exposure.      T ime shutter speed is defined  as the length of time the image sensor  in a camera is exposed to incoming light, w hen you press  the shutter button a mirror flips up  allowing light to pass into the camera  instead of the viewfinder once the  mirror is flipped upwards a small door  will move from top to bottom exposing  the sensor beneath after that another  door will fall down covering up the  entire sensor after the second door  closes your mirror will fall back into  place the doors will then reset to their  original positions underneath the longer  the shutter is kept open the more light  will enter the camera in Auto Mode   cameras will meter the scene and  determine an adequate shutter speed to  keep the picture from becoming ei...

One of the three most important settings in photography is Shutter Speed, the other two being  Aperture  and  ISO . Shutter speed is responsible for two particular things: changing the brightness of your photo and creating dramatic effects by either freezing action or blurring motion.      Shutter speed exists because of the camera shutter – which is a curtain in front of the camera sensor that stays closed until the camera fires. When the camera fires, the shutter opens and fully exposes the camera sensor to the light that has passed through your lens. After the sensor is done collecting the light, the shutter closes immediately, stopping the light from hitting the sensor. The button that fires the camera is also called “shutter” or “shutter button,” because it triggers the shutter to open and close.

What is ISO? In very basic terms, ISO is simply a camera setting that will brighten or darken a photo. As you increase your ISO number, your photos will grow progressively brighter. For that reason, ISO can help you capture images in darker environments, or be more flexible about your aperture and shutter speed settings. However, raising your ISO has consequences. A photo taken at too high of an ISO will show a lot of grain, also known as  noise , and might not be usable. So, brightening a photo via ISO is always a trade-off. You should only raise your ISO when you are unable to brighten the photo via shutter speed or aperture instead (for example, if using a longer shutter speed would cause your subject to be blurry). Note how much brighter the image gets when ISO is increased from 100 to 1600 What is the Meaning of ISO? The acronym ISO stands for “International Organization for Standardization”. However, camera ISO does not directly refer to the  organization  that...

Aperture:      In  optics , an  aperture  is a hole or an opening through which  light  travels. More specifically, the aperture and  focal length  of an  optical system  determine the cone angle of a bundle of  rays  that come to a  focus  in the  image plane . Maximum and minimum apertures      The specifications for a given lens typically include the maximum and minimum aperture sizes, for example,  f /1.4– f /22. In this case,  f /1.4 is the maximum aperture (the widest opening), and  f /22 is the minimum aperture (the smallest opening) Most important Factor in PRO  Photography:      The size of the stop is one factor that affects  depth of field . Smaller stops (larger   f numbers ) produce a longer   depth of field , allowing objects at a wide range of distances from the viewer to all be in focus at the same time. For example this pi...

To become a  Professional Photographer we must have  deep  knowledge of  camera functions or its buttons etc. In dslr  the main and  you can say (big 3) functions are  Aperture , Shutter and ISO. Each  of  them has its own function   and  to click a better picture we  must  have a deep understanding of them (  Aperture , Shutter and ISO) Aperture A camera lens functions just like the human eye.  The pupil is responsible for how much light is let in .  To allow more light to pass through  the pupil opens up or expands a nd to allow less light  the pupil closes or shrinks . Aperture works the same way.  Aperture is the opening through which light travels  and eventually hits the camera's sensor.  It is the size of the aperture's opening  that not only affects the brightness of the image  but it directly affects the area of a shot  that is in focus.  This is kno...

Difference in DSLR and Mirrorless camera Dslr      A   digital single-lens reflex camera   ( digital SLR   or   DSLR ) is a   digital camera   that combines the optics and the mechanisms of a   single-lens reflex camera   with a   digital imaging sensor .  The reflex design scheme is the primary difference between a DSLR and other digital cameras. In the reflex design, light travels through the lens and then to a mirror that alternates to send the image to either a prism, which shows the image in the   viewfinder , or the image sensor when the shutter release button is pressed. Mirrorless camera A  mirrorless interchangeable-lens camera  ( MILC ) or simply  mirrorless camera , also called  digital single lens mirrorless  ( DSLM ), is a  photo camera  featuring a single, removable  lens  and a  digital display . The camera does not have a  reflex mirror ...
