Take complete creative control over your images, with the step by step techniques provided below.
The Exposure Triangle sounds like the name of a complex spy novel, but in reality this is the term used for the three fundamental elements of exposure: aperture, shutter speed and ISO. Creating a harmonious exposure using the aperture, shutter speed and ISO is a juggling act. As soon as you make a decision about one element, you'll need to compromise with another. The trick to balancing The Exposure Triangle is to get all three elements working together so you get the results you want ,and not what the camera tells you you can have. Because of that, it's really worth putting in the groundwork and getting to grips with the basics of shutter speed how long the camera's sensor is exposed to the light , what an aperture is how much light the lens lets in, which also affects depth of field and ISO the sensitivity level of the sensor. Once you know how to do this, there's nothing you can't do. In addition to their role in exposure, the choice of aperture, shutter speed and ISO have a significant impact on the look and feel of your pictures.
The combination of aperture f-number and shutter speed determines exposure another important factor in determining exposure is ISO sensitivity, but in the discussion that follows we will assume that ISO sensitivity is fixed. Choosing higher f-numbers correspondingly darkens the image that falls on the image sensor, but you can still achieve optimal exposure if you slow shutter speed in proportion. On the other hand, you can also achieve optimal exposure by choosing a lower f-number and a faster shutter speed. In other words, there are many combinations of aperture and shutter speed that will produce the same exposure. If you always adjust shutter speed to match any changes in aperture, you can achieve correct exposure at any aperture or shutter speed.
The Exposure Triangle This guide to photographic exposure aims to help you take full control of your camera. I teach them how to take the camera off auto mode and take full control of the settings themselves in order to create the photograph they want. Why let the camera decide these things for you? Do you let your mother choose your clothes? I hope to do the same for the readers of this tutorial. I want you take control of your camera. These are: aperture, shutter speed and ISO.
From the sunset picture example, you have learned the importance of taking full control over the exposure on your camera. Now, it's time to dig into your camera and learn the three most basic tools available to you in controlling the exposure. Those tools are shutter speed, aperture, and ISO. After I explain what each one does, I'll explain why we need three separate tools to control the brightness or darkness of the photo.
When you learn photography , there comes a time when you want to move past the auto mode.Reply
When I learned exposure principles, I noticed a lot of books on the topic were very detailed.Reply
