Photography Fundamentals - Exposure Part 3 - Aperture

March 09, 2018 in Tutorial

In this next part of the tutorial series and moving on from ISO and Shutter Speed we are going to be looking at aperture and the affect it has on exposure. Some of you may already be aware that aperture not only controls your available light exposure but also your flash exposure (This is true of ISO also) but we are not getting in to flash yet, more on that much later on this blog.

The reason I want you to concentrate on just available light exposure and the fundamental exposure triangle (ISO, Shutter Speed, Aperture) is because I want you to get this nailed down before you go learning flash or buying that new camera or lens. Walk before you Run.

Photography Fundamentals - Exposure Part 2 - Shutter Speed

Next up in the Exposure tutorial series is Shutter Speed, which is one of the more creative variables of exposure. I say this because it can be use not only to control the exposure of a photograph but it can help to tell a story by controlling how you capture motion/movement (more on that in later tutorials).

What is Shutter Speed? - Shutter speed is the amount of time that your camera shutter is open for (TV Time Value). The longer the amount of time your shutter is open for the brighter the exposure will become and the shorter the amount of time the darker.

Photography Fundamentals - Exposure Part 1 - ISO

March 02, 2018 in Tutorial

Over the next few posts on The Craft Blog we will be looking at the three exposure variables (ISO, Shutter Speed, Aperture).

As we move forward with these tutorials we will break things down and work through shooting in different environment's / situations to help drill all this technical info in.

To begin with we will be looking at ISO.

What is ISO? - ISO is basically the sensitivity of your cameras sensor to ANY light source in the scene but if you want to get real technical is is digital gain/amplification control.

As we change the ISO value we affect the exposure of ANY light source within a scene. Let's break it down some more.
