What is Aperture?

This is my first ever blog on my website. Today, I will be talking about Aperture and how I use it in my photography and videography.

I have used aperture in my videos ever since I started out on photography. However, I truly started getting into it when I purchased my GH4 and also a F1.7 - F22 42.5mm lens with OIS to accompany it. With this lens I could take photos with a close up subject with a shallow depth of field all around it and also the opposite at f.22 which I find is only useful when you have good lighting, or when the picture becomes blurred and unusable. In f1.7 you get the opposite affect where in medium lighting you can achieve shallow depth of field, here is an example of f1.7 and f.22.

f.1.7 f22

As you can see in the image in the f1.7 picture the subject is in focus and the background is not. In f.22 the background and the foreground of the subject are in sharp focus.

Also another fact about aperture, if you are shooting in a higher aperture, the shutter of your camera is open for a longer amount of time allowing the camera censor to capture the whole image in focus. Side affects of this may be: if something in the photo is moving then you end up with motion blur. This can be fixed by shortening the shutter speed, but then for this you need bright lighting as the censor needs light to capture the image.
