Photography basics Three Pillars – aperture shutter ISO explained in Hindi


Hello friends on the repeating request of my many viewers want to make video in Hindi language on photography So, I have decided, I will make one video once a month on photography in Hindi language Today’s video on three pillars of the photography that I have already made three videos on aperture shutter and ISO I have already inserted the link the link of the playlist in the description, those didn’t watch till now They can watch now Thanks Friends on your repeating request So, I have decided, I will make one video once a month I must create a video on photography in Hindi As you know Photography is based on three pillars Aperture Shutter And ISO I have already created three videos in English about the same On your request again I am creating in Hindi Any new photographer or beginner Think about photography or want to learn photography They first want to know aperture, shutter, and ISO On the first part of this video I am talking about aperture What is aperture and effects of aperture After that, I will discuss shutter and ISO Because of these three things are the main base of photography let’s watch What is aperture Aperture is a hole within a lens, through which light travels into the camera body. Let’s watch how it happen and how it works It is an easy concept to understand for those who just think about how your eyes work. As you move between bright and dark environments, As you know the iris in your eyes either expands or shrinks in darkness or light controlling the size of your pupil. In photography, the “pupil” of your lens is called your aperture. Everyone knows that your pupils will change size according to the amount of light you are experiencing. With more light, the pupil constricts and becomes smaller. Less light and your pupil dilates, letting more light into the back of the eye. like eyes, the aperture allows you You can shrink or enlarge the size of the aperture, more or less light to reach your camera sensor. as you required Aperture has several effects on your photographs. One of the most important is the brightness or darkness or increasing or decreasing exposure As for aperture changes in size increase or decrease it alters the overall amoun t of light that reaches your camera sensor and therefore the brightness of your image. A large aperture (a wide opening) will pass a lot of light, resulting in a brighter photograph. A small aperture does just the opposite, making a photo darker. Take a look at this clip to see how aperture affects exposure The other critical effect of aperture that subject appears sharp from front to back is something known as depth of field Some images have a “thin” or “shallow” depth of field, where the background is completely out of focus. Other images have a “large” or “deep” depth of field, where both the foreground and background are sharp. Most likely, you have noticed this on your camera before. On your LCD screen or viewfinder, your aperture will look something like this: f/3.5, f/5.6 or f/16 Some cameras omit the slash and write f-stops like this: f3.5, f16, For example, the camera below is set to an aperture of f/8: it means aperture size is a f/8 Aperture is labeled in f-numbers. In this case, I’m using an aperture of f/8. So, f-stops are a way of describing the size of the aperture. for a particular photo On this part of the video I will discuss the other pillar of photography What is the shutter? & what are its effects Shutter speed is basically responsible for two particular things First changing the brightness of the subject And creating dramatic effects of freezing the action and blurring the motion Blurring means any moving subject in speed or subject in motion to expose its speed or movement or to show the subject in movement or in speed In this part, I will explain all about shutter
& shutter speed shutter speed exists because of something known as your camera which shutter simply put 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. When it comes to a DSLR camera shutter there are 3 basic mechanisms: the mirror box, the bottom door, and the top door. When you look through a DSLR view finder you are essentially looking through a series of mirrors that get their light directly from the lens. When you click the shutter button that system of mirrors flips upwards to allow light to pass to the sensor This is why the viewfinder goes black
for a short amount of time when taking photos. 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. This process can vary in time depending on
the length of your shutter speed. Sometimes a shutter speed can be so fast sensor won’t be entirely exposed at any one time. After the second door closes your mirror will fall back into place. The doors will then reset to their
original positions underneath. This entire process from the mirror up to mirror down is known as an Actuation. It is typically very easy to find the shutter speed. On cameras that has a top panel, the shutter speed is typically located on the top left corner, as circled: If your camera does not have have a top LCD, like some entry-level DSLRs, you can look through the viewfinder, where you will see the shutter speed on the bottom left side And if your camera has neither a top LCD nor a viewfinder, like many mirrorless cameras, you can see your shutter speed simply by looking on the back display screen. you can see your shutter speed simply by looking on the back display screen. the shutter is open, shown in seconds
or fractions of a second: like 1 s, 1/2 s, 1/4 s … 1/250 s, 1/ 500 s, etc. The faster the shutter speed, shutter speed, the shorter the time the image sensor is exposed to light; In other words less light reach to the sensor the slower the shutter speed, he longer the time the image sensor
is exposed to light. If you are photographing a subject
that is in motion, you will get different effects at different shutter speeds. Fast shutter speeds will “freeze” motion,
while slow shutter speeds introduce blur from two sources: camera movement known as also (camera shake) and subject movement the faster the shutter speed the easier it is to photograph the subject without blur and “freeze” motion and the smaller the effects of camera shake. In contrast, slower shutter speeds are suited to suggesting the motion, such as that of flowing water or other moving subjects. Changing the shutter speed gives you
control over whether to “freeze” or suggest motion. A darker picture is produced when the shutter moves very quickly to touch the imaging sensor for a tiny fraction of a second. of 1/2 of a second will allow more light to touch the image sensor and will produce a brighter picture than a shutter speed of 1/200 of a second. Now I am telling about that pillar of photography That we know as a Camera ISO You are surprised to see that what is the relation of photography of these mugs some numbers are printed here I am discussing these numbers When we shoot with film cameras in our old days, We kept several films of different numbers
in our camera kit. And in different lighting conditions, different films used to suit the requirements. I personally used Fuji Velvia, Sensia, and Provia
. 50 printed on Velvia, Sensia & Provia come with 100 to 400 numbers Actually, these numbers are represented to
ISO. One of the three pillars of the photography that can dramatically affect your images the other two being shutter and aperture. That we have already discussed In this video of Photography Basics part-III. I will explain ISO. by using simple examples so that you can make the most of it. for your own photography. 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. So, ISO is a good tool to capture images in dark environments However, increasing ISO has consequences. A photo taken at too high of an ISO will show a lot of grain , also known as noise. In the days of film, as you used film with
higher ISO values, your images had more visible grain. You could easily see these pictures. In digital cameras, raising the ISO means a similar decrease in quality, as a result
increase grains called “noise.” The difference is clear in these two pictures the image at ISO 10000 has much more noise than the one at ISO 100 This is why you should avoid high ISOs whenever possible, unless conditions require you to use them Every camera has a different range of ISO
values or ISO speeds Every camera has a different range of ISO
values or ISO speeds 1600,3200,6400, 12800 High ISO So, a photo at ISO 400 will be twice brighter than ISO 200, which will be twice brighter than ISO 100. You can see as I raised ISO 100 to 200 Picture has brighter than ISO 100 So the same way as I raised it 200 to 400, a picture has brighter than 200 photos. You can also see the difference of the levels in a histogram showing here The pictures we took at 100 200 and 400 ISO Changing your ISO varies from camera to camera For entry-level DSLRs and mirrorless cameras, you probably need to open a menu and find
the section for ISO. Select the value you want, or set it to Auto. For higher-end cameras, there may be a dedicated “ISO” button on the camera. Press it while spinning one of the wheels
to change your ISO setting. Turning on that feature allows the camera to push the ISO up. when it decides the shutter speed is getting too low for a good picture. Even better, newer new cameras have added “ISO Sensitivity Auto Control” to the menu choices. ISO will increase or decrease automatically according to the lighting condition even camera set on manual mode You can see the menu of my Nikon Camera, where I selected ISO Sensitivity Auto and displaying ISO-Auto On the display panel Here are some ISO sensitivity settings that I will discuss in my next coming advance video Till then share the idea with and also comment So, I will create those videos that you want to watch Kindly tell me, How did you like my first Hindi video Don’t forget to subscribe also, click on the bell Thanks for watching
