Photography Tutorial: Aperture, Shutter Speed and ISO

Hello everybody! Photography tutes are back! This time, I want to cover the basic topics of shutter speed, aperture (f-stops) and ISO. If you have a DSLR or a Mirrorless camera, you are good to go! The video tutorial is quite short (about 11~ minutes), and the idea was that you could follow up with your own camera.

There is a photography challenge at the end of the video! It is just 2 photos that you should take on the same sitting, just playing with your settings. I'd love if you can join in! So, without further ado, here is Cookie helping in on this tutorial:

There is not much for this video, but here are the definitions I explained:
  • The shutter speed is the length of time the camera shutter is open, exposing light onto the camera sensor. The negative side effect is that the camera and the subject need to be still for more time. Also, at slower speeds, you cannot hand-held your camera.
  • The ISO is a sensitivity to light. The more ISO, the more bright the photo gets. A negative side effect is that the photos become noisy or grainy.
  • The aperture is also referred to as f-stops.It indicates how open or closed are the blades of your lens. This changes two things: the depth of field (simply put, it shallows the zone in which the lens can "see" sharply), and the brightness of your photo.

And for the challenge: You need to take 2 photos of your doll. One needs to have blurry background and the other a sharp background. But they need to look the same except for that! Let me show you. The whole video explains how to do this, and at the end, you have a comparison of both of my photos, with the settings. Here is a half-and-half of my two photos. You can just take them individually, but I wanted to show you the idea!

And that is all for today! I know it is short, but that video took me about 12 hours to make, so I think I invested enough effort in this post. Anyways, I hope you join in the challenge!


  1. Hello! I'm going to check out that tutorial and try to join the challenge. Even though I don't own a professional camera, I believe my phone also allows to control those settings. I do know what most of the photography concepts mean, but I don't really understand how they interact between them.
    Thanks for the tutorial, I'll let you know how the challenge has worked out.

    1. Yes, some phones allow you to control a lot of things. Otherwise, if the default app doesn't, there are several free camera apps that would allow you to do it. Can't wait to see your result!
