![]() Once you’ve understood aperture, shutter speed, and ISO, you need to learn how each element of exposure work together. © Tom Podmore (Unsplash) Exposure Summary There’s no possible way to fix that in post-production (yet, at least). So you have to decide upon your priorities in terms of exposure versus the amount of grain.įor example, I would reduce the image quality if it meant that I could prevent motion blur in my photo. There will be more digital noise or “grain.” But, at the same time, the image quality decreases. This is where we decide how to set the ISO.Īs you turn the ISO number up, you increase the brightness. Once the light has passed through the aperture and is filtered by the shutter speed, it reaches the camera sensor. That’s why knowing how your shutter speed works is a key emphasis in photography basics. It all depends on what you’re shooting and how much light you have available. Shutter speed can be anything from really fast (1/4000 s) for sports photography to really slow (30 seconds) for night photography. But different shutter speeds complement different situations. Ordinarily, you only want a very small fraction of a second (for example, 1/250 s) to prevent motion blur. Now you must decide how much light you will allow into the camera. Once the light has passed through the lens’s aperture, it reaches the shutter. Some specialty lenses go above and below this scale. But, if you want to create motion blur, it is second to the shutter speed.Įxposure will be much easier if you can memorize the f-stop scale. The aperture is the preferred setting to set first, as it directly influences how much of your scene is in focus. But it makes the field depth very shallow and is not ideal for landscape photos. And more light is allowed into the camera. Simple? Not quite.Īs the aperture widens, the f-number gets lower. The wider the aperture, the more light is allowed into the camera, and vice versa. This is the hole inside the lens through which the light passes. This is a summary, but I go into full detail about it in our post on aperture. So let’s explore exposure in the three settings we’ve mentioned 1. This is where you take control back from your camera. You can dive into manual settings once you understand how each one works. They also cause alterations in depth of field, motion blur, and digital noise. That is if you photograph the same scene with the same lighting conditions.Īs you’ll soon learn, these elements affect more than exposure. This will help you understand that changing one setting will require changing the others. Combined, they control the amount of light captured from any scene. The exposure triangle is a great way to remember the three settings. Shutter speed, aperture, and ISO are the elements that combine to create an exposure. Learning how exposure works will help you take control of your camera and take better photos. The following will make understanding exposure and how cameras work much easier!įor those beginning photography, exposure is key to capturing a great image. I collaborated with an illustrator friend, and together we made these images. So I thought, “What better way to help beginner photographers learn how to use their cameras than by creating an infographic?” And that’s exactly what I did. And it’s my job to make beginning photography as easy as possible for you. Plus, we’ll look at some photography terms and suggest some equipment to get you started.Īs beginner photographers, we tend to be visual learners. ![]() We’ll go over some camera, lens, and composition basics.
