So the lens opening is fully open, meaning that the most light gets through the lens to the camera sensor. Now if we take my go to lens for real estate photography, the Canon 17-40mm F4 L lens, the maximum aperture is F4.
The aperture is built into a camera lens, and is made up of a series of interlocking metal (probably) blades that open and close when you change the aperture setting, letting more or less light in. Or anywhere, ever.īut I can tell you this – you can adjust the size of the opening by changing the aperture which changes the amount of light passing through the camera lens to the sensor. It does this by some electronic process way beyond my technical capabilities and understanding that I will not explain here. We need to remember that the camera sensor is recording the light that reaches it and converting it into a digital photo. The aperture is the size of the opening in a camera lens that lets light pass through the lens to the camera sensor.
Hopefully I have made the point and we can now crack on with this.Īnd before I do I will cover the best shutter speed and ISO settings in future blog posts. These terms are logical and conventional, and there is no use of the word F Stop here. These three settings combine to create the exposure when you take a photo. The exposure triangleĪperture is one of the three camera settings that make up the exposure triangle. So from now on I will use the term aperture rather than F Stop. If we got rid of the term F Stop and stuck with aperture I don’t think we would miss it. I could go into this more, but it won’t help us.
Strictly speaking F Stop takes account of both the opening dimension of the camera lens, and also the focal length used. Well you could argue no, but using aperture instead of F Stop amounts to the same thing, being the value of the aperture setting on the camera lens that relates to how much light passes through to the sensor. I know, it is one of those terms that can be confusing, so let’s keep it simple. But as far as I am concerned F Stop and aperture are one and the same, so from now on I will refer to aperture only OK? Well F Stop is a term used to describe the amount of light that gets through a camera lens to the camera sensor.
