If you’re just starting out with photography, the relationship between ISO, aperture and shutter speed is one of the crucial things to learn. However, it can be difficult to grasp if the concept is new to you. In this great animated video from Apalapse you’ll easily learn the relationship between the three parameters and how they affect the exposure and the look of your images.
When you think of lens aperture on your camera – do you think about exposure, or do you think about artistic interpretation?
Yes, aperture is one third of the exposure equation (with shutter speed and ISO making up the other two variables), but your choice of aperture should primarily be an artistic choice.
If you’re moving up to a DSLR from a mobile camera, you probably haven’t really thought about aperture too much (since phones have a fixed aperture) – or if you have, it’s in terms of bokeh (wider aperture = more bokeh…yay bokeh), but your choice of aperture has a big impact on the look of your captured image (beyond just bokeh).
In this article, I will show you the difference between using a small, closed aperture and a big wide open aperture when it comes to sun flare and specular highlights.
One of the most commonly asked questions by new photographers is what exposure settings they should be using to get correct exposures. Unfortunately, this is also one of the most difficult questions to answer because of the seemingly endless amount of variables involved in calculating such settings. There are always situational elements such as available light, motion, and other things that we can use to help us determine correct camera settings, but outside of those tangible variables, a photographer must also take creativity into consideration. How do you want the photo look?
In this quick primer on exposure settings, Bryan Peterson discusses the notion that just because a photograph is exposed correctly on a technical level doesn’t necessarily mean the exposure settings were the right ones.[Read More…]
