The Exposure Triangle - Aperture

MainLineBreak.png

Now that we have learned a couple of the basics of photography in previous lessons... composition, leading lines, symmetry, we are going to jump in a little more about the pieces of the exposure triangle and gaining control over your photos.

The Exposure Triangle is composed of three different parts. The three parts of the Exposure Triangle are APERTURE, SHUTTER SPEED, and ISO and they all work hand in hand with each other to create the perfectly exposed photograph, or to make a photograph that fits your artistic vision. We will be going over each one of these in different lessons. This lesson will focus on the APERTURE side of that triangle.

The Aperture is defined as the space through which light passes in an optical or photographic instrument, especially the variable opening by which light enters a camera. You can think of it as the camera's eye. Much like our eyes, the aperture can open wide to let in more light or close to let in less light.

For this lesson we are going to take control of the aperture on your cameras. All DSLR's and most all point and shoot cameras have options to go into what is called APERTURE PRIORITY mode. Camera's will either have a dial you can turn it to with an 'A', 'Av', or it can be set through the menu.

Setting your camera into Aperture Priority mode will give you the control over your aperture opening, but the camera will then adjust the shutter speed and possibly your ISO automatically if you have it set to do that. Aperture F-Stops are kind of like your eye's pupil. The bigger it is open, the more light it lets in. A photo shot with a smaller aperture will have a slower shutter speed, so a tripod may be necessary.

Aperture will also effect your Depth of Field or how much is in focus. A larger aperture opening will create a smaller DOF while a smaller aperture will have most everything in focus. Using a smaller DOF, you can isolate your subject from the background of the image making it more pleasing to look at and less distracting. A larger DOF is great for landscape photography when you want everything in focus.

Fundamentals in Action

In this shot I used a large aperture to blur out the distractions in the foreground and background of what I was seeing. This crane was in a fence at the zoo. Shooting it with a large aperture opening, it caused a smaller depth of field that I was able to get the fence in the foreground as well as the background to blur enough to where you almost don't see it at all.

Then this image was shot with a very small aperture creating a big depth of field. In this way, I was able to get the sign in the foreground in focus as well as the huge rock formation. I lined it up enough to where the stopsign looked like it was posted on the rocks.

Using a large aperture in this image, I was able to isolate the single seed from the dandelion and just bring focus to it as it clung on. With the grass out of focus as it is, it created a pleasant background and contrast.

Then finally with this image, I used a very small aperture. I did this not to make sure everything was going to be in focus, but by having a small aperture it made the exposure time longer creating a blur effect with the water running through this rock.

Homework

linebreak2.png

For this lesson's homework we would like you to shoot 2 different photographs. Remember to use the techniques and things you learned from the previous 2 lessons.

  1. For the first photo, find a subject and shoot with a wide open aperture. Take an additional image and show how a small aperture would not work with a larger Depth of Field.

  2. With the second photo, use a small aperture to get everything in your image in focus.

Also in your post, let us know what you learned as you played with the aperture settings, some challenges you may have run into, and if you had anything that may help others as they learn in this photography adventure.

    2. Overall understanding and application of the lesson elements.
    3. Structure of lesson post and design.

  • Rewards will be as follows:

    • 5 Pixel for an average post that meets the minimum requirements.
    • 10 Pixel for a good post that shows some good elements to it, with good structure and photography or art.
    • 15 Pixel reward is reserved to the exceptional posts that we feel the authors have gone above and beyond and truly taken the time take what they have learned and apply it and share it with the Whaleshares platform.

This is a great post! I have often been amazed at how by understanding depth of field/aperture you can really make something that would otherwise be incredibly boring, somehow look interesting.

I literally just now took this while writing this as an example. I'm obviously no pro photographer, I just do it for fun, but I can appreciate where it can be taken. Thanks for posting the tips!

Awesome picture. You should definitly join the Pixel Perfect discord and do the homework assignment and start earning some sweet rewards.

Great shot, you should definitely go for this homework!!!

Thanks, I got really busy with work, but really want to get involved. I have to make some time for creativity!

This is an excellent shot. I have learned over time that beauty is in the eye of the beholder. I saw a post on the web today like a top 10 photos for 2018 and some of those shots were scrap. However because he / she is a pro... they say wow!!! lol

That is how I feel every time I go into a modern fine art gallery. Certain people are promoted as geniuses for drawing a line on a canvas or a scribble.

The reality is that even though they stick up their noses at professional working artists, many of these so called fine artists would be completely unhirable in the industry.

Fantastic, this lesson was well worth the wait! Your example photos are top quality and I will be racking my brains as usual to choose the right options for this homework! Although I have a few ideas already!!!!

Oh this is where I really need to sort myself out. I've been trying to do everything at once and the "Exposure Triangle" is what brings me undone. (Possibly while doing composition I should just have shot in auto). I gotta stop overthinking!

This should help me a lot

We will be releasing lessons in regards to each element of the exposure triangle and then at the end we will be summing it all up with a final lesson and have you all incorporate each piece of the triangle at once.

beauty of writing lesson, excellent lesson

really awesome post, I really like your post

I wish I was half as good as you ...
