The Exposure Triangle Explained
Think of the exposure triangle as your camera's control centre - it's made up of three settings that work together to determine how your photo looks. These three elements are aperture, shutter speed, and ISO.
Here's the crucial bit: when you change one setting, it affects the other two. It's like a seesaw - everything needs to stay balanced to get a properly exposed photo. Master this balance, and you'll never take another accidentally dark or overly bright photo again.
The diagram shows how each setting affects brightness. Moving towards the "brighter" end of each scale lets more light into your camera, whilst moving away reduces the light. ISO ranges from 100 to 1,600 (and beyond), shutter speed from fast (1/250) to slow (1/4), and aperture from wide to narrow .
Quick Tip: Start by learning one setting at a time, then practise adjusting the others to compensate. Soon it'll become second nature!

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
