Lens, Aperture, and Shutter Speed
Okay, listen up. Because what I'm about to tell you is perhaps the most important thing you'll learn in the entirety of this course lens, aperture and shutter speed of the only control in your camera that directly affect the aesthetics of your photographs. Get to grips with these two controls and you're 90% of the way to completing the first step in becoming a master photographer. We've already seen how lens aperture controls the amount of light coming into the camera. But Lens aperture also controls depth of field. That is how much of the scene, from foreground to background appears sharp. The thing about depth of field is it controls emphasis, that is, which objects all areas in the scene people pay attention to on which they ignore. Now let me explain why human beings focus our attention on objects at a sharp, and we ignore objects of the blood. The more blood they are, the more we ignore them. Because your attention has been on May, you probably haven't noticed is large waste own b...
ehind me until now, by changing which objects appears sharp in the picture space, we change emphasis. So in composition, using depth of field weaken visually, remove distracting objects by blurring them, and isolate and emphasize important ones. Conversely, if every object in the scene is important to your story, such as in a traditional town scape or landscape, you can use depth of field to create foreground to background sharpness and take people on a visual journey throughout the image space. In other words, emphasis is on the whole space, essentially depth of field, which is controlled by lens. Aperture is a compositional tool for including or removing visual objects from the picture space way. Theo Speed allows you to control how time appears in a photograph. You can use a far shutter speed to freeze time revealing detail and form or slow shutter speed, which blurs time, creating a sense of motion and speed on the slow of the shutter speed, the more abstract the image. Now what constitutes our fast or slow shutter speed depends entirely on the subject. It's all relative. For example, the shutter speed needed to freeze the movement of the world's fastest tortoise would be very different to that needed to freeze the motion of a cheater in hot pursuit of a gazelle, say the cheetah would need a shutter speed in the one thousands. The tortures in the one tents andan this example shutter speeds of 1 4/1000 on 1/40 would both be considered fast relative to the subject. That said, as a rule of thumb for action shots of subjects such as animals and sports, I want to shutter speed, pushing 1 1000 for faster to reveal the movement of the same subjects. I would typically be setting my camera to a shutter speed of between 1/10 on 1/30. So to sum up, we've determined that lens aperture controls emphasis on shutter speed, determines how you reveal time. We refer to these as the exposure variables on part of your job as a photographer is deciding which of the two lens aperture or shutter speed is the dominant variable. What you decide will determine the best exposure mode to use
