What is Exposure Triangle in Photography?

Hello everyone, This is Ayush Raj, back to you with a new blog. Today we are going to learn about the Exposure Triangle, which most of you are familiar with. But still, be with me!

When we talk about Exposure, what comes in your mind? Exactly, Light. So, where does this light come from, in an image? That’s right, from using aperture, shutter speed, and ISO. Now, in photography, getting a decently exposed image which can be controlled by us, is very crucial.

That’s where Exposure Triangle comes in.


Exposure Triangle Explained


As you can see, we pointed out three basic features in the Exposure Triangle Diagram:-

  • ISO
  • Aperture
  • Shutter Speed


We will learn how to bring out the relationship between these trios to get a well-exposed shot.


  1. ISO ISO is the level of sensitivity of your camera to available light. Its value is determined by numbers: the lower the number, the lower the sensitivity to light. The lowest value goes to 50 and the highest value goes to 102,400. The important thing to understand is that each step between the numbers effectively doubles the sensitivity of the sensor. If I’m in dim conditions, I can increase the ISO to make my sensor more sensitive to light. If I’m in bright conditions, I can lower my ISO.

ISO 200 > ISO 100 – x2

ISO 400 > ISO 100 – x4

Now, if I compare ISO 400 to ISO 100, it is 4 times more sensitive to light. So, always use ISO carefully since it can bring a drastic change in exposure and grain in your image. Always prefer the lowest ISO value when shooting outdoors. This is the first part of the Exposure Triangle.


Let’s move on to the next element.


2. Shutter Speed = Shutter speed is the length of time light is allowed to hit the sensor.

Shutter speeds are typically measured in fractions of a second when they are under a second. For example, 1/4 means a quarter of a second, while 1/250 means one-two-hundred-and-fiftieth of a second (or four milliseconds). The other important effect of shutter speed is on exposure, which relates to the brightness of an image. If you use long shutter speed, your camera sensor gathers a lot of light, and the resulting photo will be quite bright. By using quick shutter speed, your camera sensor is only exposed to a small fraction of light, resulting in a darker photo.

Shutter Speed


3. ApertureWe often want our camera’s aperture to work like the pupils in our eyes. In bright light, our pupils become small to limit the amount of light that we see. In the dim light, our pupils get large to let in as much light as possible and increase how much we can see.

In photography, we call it aperture. Aperture and shutter speed work together to determine how much light hits the sensor. I can set my aperture and use shutter speed to balance the light. Or I can set the shutter speed and use aperture to balance the light. Aperture controls how much light hits my camera’s sensor. It also controls how much of the scene is in focus. This is called the depth of field (DOF). A wide DOF means that more of the scene is in focus. A shallow DOF means only some of the scene is in focus. In terms of aperture, f2.8 will generally have a shallower depth of field than a smaller aperture like f16. More of the scene will be in focus at f16, but f2.8 might give me a beautifully blurred background (bokeh).


What are Stops?


For any given exposure, if one of the three variables change, you must adjust one (or both) of the others in the opposite direction. For example, if you decided to decrease your shutter speed by two stops, you will need to increase your aperture or ISO by two stops. You could also change both aperture and ISO by one stop with the same effect. As another example, say you increased your ISO by four stops. Then you would need an equivalent decrease of four stops in aperture or shutter speed (or a combination of the two). It sounds a little confusing, never mind. Watch the below diagrams to understand better and process it. Ask me freely wherever you have any doubts or didn’t understand.

How to View and Recover iTunes Backup files on Windows? – Ayushraj

iPhones are known to be one of the most popular phones ever and Apple provides one of the best services in the world to its customers. But at the end of the day, these are still devices, and devices are unpredictable. You never know when the data on your iPhone corrupts or your entire iPhone crashes. One of the best way is to keep your information safe is to have backup.  iTunes will be the topic we’ll cover today..

Backup of your device at regular intervals is important to safeguard your data. Corruption can occur anytime, either completely or partially and that is why backing up becomes essential. Lets talk about iTunes .

How to backup iPhone data?

There are two main ways through which you can backup your iPhone data:

  • Using a computer: You can store all your data as a backup in your personal computer. Apple products are known to have unfriendly relations with other devices , when it comes to connectivity . Your computer need not necessarily be Macbook or an iMac to take the backup of your phone. Since you need iTunes software for backup . iTunes is available for both Mac and Windows, it becomes for the users to safeguard their data.
    All you need to do is install iTunes on your system. Then open it and login with your Apple ID. Once iTunes is open, connect your iPhone to the system. Make sure that the phone’s power is on. Once a phone is successfully connected, click on ‘File’option on the top corner menu in iTunes Window and choose Devices. Now you will be able to see all the information about your device including its serial name and the amount of memory in it. Just near it, you will find a button ‘Backup my Phone’ . Click on it and all your phone’s backup will be automatically taken by iTunes.


  • Using iCloud: As you know, through iCloud we can save our data on off-site servers, access it from anywhere and save our local storage. Apple has its own Cloud storage service called iCloud. The only thing you need to back up your files in iCloud is a good internet connection. One small drawback with iCloud is that only 5GB data storage space is free. If you want to expand this space, there are extra charges for it. But iCloud is a safer way to store as there is no chance of losing data by system crash or malfunction. To back up your data to iCloud, you need to go to Settings, select iCloud and login to it. Then you can select all those apps whose data you want on the iCloud.


Issues with iTunes in Windows

iTunes sometimes might crash or not work on a Windows operating system. In the earlier version like Vista and XP the issue was prevalent but now with so many updates the issues have been very rare in Windows 10. But yet if you face issues running iTunes on Windows, here are few things which you can try to resolve the issue.

  1. Check for updates of iTunes for Windows. If there are any new updates, install them and then try running the program. This would solve the issue.
    If there are no updates available and it shows issues, then you can try running iTunes in safe mode to see if it is the App issue or the system issue. If it works perfectly fine in the safe mode, then uninstalling the plugins should resolve the problem..
    3.  You can disconnect your computer from the internet and try opening the iTunes again

The simplest thing to do would be to restart the computer and try to open iTunes.



How to Restore Backup to iPhone

If you did take your backup through iTunes or iCloud, then you can directly restore your backup.

When you connect your phone to your system through iTunes, you will get an option to restore the backup right next to the ‘create backup’ option. But what if the backup files iTunes created have been corrupted or affected by the virus? Don’t worry guys. All your phone data is in those backup files and without them, you really cannot recover your data.

There is no manual way to recover iTunes backed files . But you can take the help of a third party tool for that. There are many tools available in the market that can help you out with this . But we strongly recommend Stellar Phoenix Data Recovery for iOS. This amazing software can recover lost or deleted data from all iPhones such as 6s, 6+,6, 5s, 5, 4s and 4 as well. It supports iOS 6.x, 7.x, 8.4, 9.0 and above versions. Well it can recover contacts, photos, iMessages, notes, reminders and even WhatsApp messages. It has a very easy-to-use interface and it recovers data quickly.
