Sometimes, the world just seems to look better through the viewfinder than the eyes and just as we close our eyes for a second or so, the scenario changes completely. Now, incorporate the sound of shutter and imagine if you could adjust the brightness of the image, won’t that be a deal-breaker? Here we are today, saying hello to our Cameras, getting acquainted with its parts, and finally, snapping a great outcome!

[vc_row][vc_column][vc_column_text]So what exactly is the relation of Shutter Speed, Aperture and ISO? Before jumping in the details, note that the 3 elements mentioned above get together to form ‘The Exposure Triangle’, the King of Photography. Also, let’s incorporate a Gas Stove to the apparatus in our head, just for making it all easy.[/vc_column_text][vc_row_inner][vc_column_inner width=”1/2″][vc_single_image image=”2609″][/vc_column_inner][vc_column_inner width=”1/2″][vc_single_image image=”2610″][/vc_column_inner][/vc_row_inner][vc_column_text]1. Shutter SpeedNow imagine a stove. If you want to boil some milk and you want it to be bubbling fast, you will set it on flame for X amount of time. That is what shutter speed is for you. The shutter determines how much time the sensor will be exposed to light. If we stick to the basics, faster the shutter speed, more stable and sharp your image is ought to be but on the same line, as the shutter is dropping fast, the intake of light reduces, leading to a darker photo. So basically, if you keep the milk for too long, the milk may overflow and then, you may have to spend some time cleaning your kitchen top. We don’t want that, do we?[/vc_column_text][vc_row_inner][vc_column_inner width=”1/2″][vc_single_image image=”2613″][/vc_column_inner][vc_column_inner width=”1/2″][vc_single_image image=”2612″][/vc_column_inner][/vc_row_inner][vc_column_text]The first image has slow shutter leaving the man blurred while the second photo is having a higher shutter speed, hence, the subject seems to be in focus.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]2. ApertureThe size of your stove is your Aperture! Larger the size and opening of it, the faster the milk will boil. As simple as that sounds, Aperture is the set of blades on your lens that lets light enter your camera. If the aperture is wide, the light that will walk into your sensor will be more and vice versa. But here is a click- when the opening broadens, the aperture or what we call as ‘F-Stop’ decreases! Also, Aperture gives you complete control of blurring the background. Higher apertures like F/ 1.4 or F/ 1.8 give you a complete bokeh image. To sum it up, if you set your vessel on the largest stove, it may get heated quicker and again, good bye clean kitchen tops![/vc_column_text][vc_row_inner][vc_column_inner width=”1/2″][vc_single_image image=”2615″][vc_column_text]F/8[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/2″][vc_single_image image=”2616″][vc_column_text]F/1.4[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]3. ISO The flame is the ISO. Apparently, you may not have liberty to choose the size of your stove sometimes but does that stop you from boiling milk? Nope! You set it on some stove with a high flame. ISO determines the sensitivity of your camera towards light. You can keep the flame low, medium or high, as per your choice but if you keep it high, it will come at a cost. The milk may start thickening and may get stuck to the base. Similarly, if you set the ISO too high, your image may turn out to be grainy and over exposed. The ‘Noise’ will also increase, leading to a pixelated and not an eye pleasing photo.[/vc_column_text][vc_row_inner][vc_column_inner width=”1/2″][vc_single_image image=”2623″][vc_column_text]Here, we see noise or  grains at the bottom.[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/2″][vc_single_image image=”2619″][vc_column_text]ISO here is set well and hence, grains aren’t observed despite the darkness around.[/vc_column_text][/vc_column_inner][/vc_row_inner][vc_column_text]So now, we can say that you are handy with our stove. What next? We now need to know how these elements work in unison to hand us a good photo. Let’s construct some scenarios.

  1. There is a family get- together. All smiles and dances are imbibing a happy atmosphere and you don’t want to let go of the moment. To snap that, you set your ISO ranging from 400- 800 and as you are snapping family, you don’t want to focus on just one person, so you set the Aperture to F/ 3.5- F/ 4.3. The aperture and the ISO are set but the subject seems to be moving. You now set the shutter speed ranging between 1/250- 1/500 and click! Now you are the one smiling for snapping a good photo!

The same people stayed back for the evening and now, the party is taking place in full pomp. The light has reduced but again, you are the family’s cameraman, so your show must go on as well. You want to capture the smiles now, so you aim for portraits. The ISO stays stable around 800-1600 to top and your shutter relaxes at 1/125- 1/500, as needed but if you increase it more, your photos may turn out to be dark and if it goes too slow, your photos may look shaky and blur. The Aperture stays open at F/ 1.8- F/ 2.4, allowing the light to pass in the camera. You release the shutter and all you get is a beautiful photo that goes in the memory box!
