I’m taking you in a different direction today.

Instead of a post about pictures I’ve taken, I want to help YOU learn more about photography. I’m going to share a little series of photography tips that (I hope!) help explain the fundamentals of photography. Digital cameras have made it easier than ever to jump into the art of photography but there are still some basic techniques that will make you, as a photographer, even better. And let me say that I didn’t know any of what I am about to share with you until I took my first photography class in college – I was very much a beginner!

The first thing I want to share is the exposure triangle. The three ‘points’ of the triangle are apertureshutter speed, and the ISO. This trio of settings determines your overall exposure; how bright or how dark the picture is. Each setting affects the other two, so learning about each of them and how they work together will help you to control your exposure.

In this first post, we’re going to focus (pun intended!) on the aperture ‘point’ of the triangle.

Aperture refers to how wide your camera’s lens is opening. In camera-lingo, this is called an ‘f/stop’. Your camera’s aperture setting will determine how much or how little light is coming into your camera, as well as how much or how little of the picture is in focus (depth-of-field).

A wide aperture would be a low f/stop like f/1.4 or f/3.5. Your camera’s lens opening is very wide  (see the illustration above) which allows lots of light to come into your camera. A wide opening also makes your depth-of-field very shallow. So if we use a wide aperture, we’re going to let more light into the camera but less of our picture will be in focus.

In contrast, a narrow aperture would be a high f/stop like f/11 or f/16. The lens opening is narrower, which lets in less light. The depth-of-field would be larger, allowing more of the picture to be in focus. So if we use a narrow aperture, we’re letting less light into the camera but more of the picture will be in focus.

Confused yet? Stay with me! Let’s look at some examples.

aperture

 Here we see five pictures of the same subject, all taken with a different aperture setting. On the very top the camera had a wide aperture. See how the book starts to get blurry and the wicker table is completely out of focus in the background? On the very bottom the camera had a narrow aperture. The book is completely in focus and we can see much more detail in the wicker table.

So how do you control aperture on a point-and-shoot camera? The landscape setting on your camera (usually shown by a mountain symbol) will give you a narrower aperture. Typically when you are shooting landscapes you want a lot of your picture to be in focus, so you want a higher f/stop. Even if you aren’t taking a picture of a landscape, you can use the landscape setting on your camera to get a narrower aperture and higher f/stop.

aperture3

What about wider apertures? Look for the portrait setting on your camera – the little face symbol. The portrait setting is (obviously) designed for taking pictures of people. Generally when you are shooting portraits, you’ll want a shallow depth-of-field and a wide aperture. Just like the landscape setting though, you can use it whenever you want a lower f/stop.

Let’s review for a minute.

  • Aperture is how wide or how narrow the lens opening of your camera is.
    A wide opening allows more light into the camera and gives a shallow depth-of-field. A wide opening would be an f/stop such as f/1.4 or f/3.5.
    A narrow opening allows less light into the camera and gives a wide depth-of-field. A narrow opening would be an f/stop such as f/8 or f/11.
  • To get a narrow aperture (low f/stop number), look for the Portrait setting on your camera.
    To get a wide aperture (high f/stop number), look for the Landscape setting on your camera.
  • Aperture works together with the shutter speed and ISO settings to produce the exposure. This is called the exposure triangle.
  • Check out the Digital Camera Simulator to learn even more about how aperture works.

I hope I didn’t lose you along the way. Please comment with any questions you might have! And stay tuned for the next part of this series. We’ll talk about shutter speed, the next point of the exposure triangle!

What My Son Taught Me About Joy at the Holidays

In: Fatherhood, Uncategorized

There’s not a lot going on right now, but that doesn’t mean my family can’t still enjoy some of our favorite seasonal pastimes like trimming the Christmas tree, counting down to Santa’s arrival, and riding bikes around the neighborhood and loudly critiquing everyone’s decorating choices. Amidst the December doldrums, the announcement of a holiday decoration contest by our neighborhood HOA certainly sent a frisson of excitement through our household. My children are enamored with decorations anyway, but the prospect of a cash prize just for filling our yard with more inflatable monstrosities dialed up their excitement level to an 11....

Christmas Magic May Look Different For a Special Needs Family

Christmas can be a very magical time of year with Santa, decorations, presents, and family gatherings. It can also be a very tough and difficult time for families with special needs children. For many of us as parents, we are hanging on by a thin thread as we try to honor the traditions of our extended families while keeping our children with special needs happy and on routine.  My son was diagnosed with autism spectrum disorder at 21 months and is non-verbal. He is now 5.5 years old. He doesn’t like the noise or chaos that gatherings bring. Sometimes lights...

Why Didn’t We Think of That? Dad Invents Candy Chute for Contactless Halloween Trick-or-Treating

In: Uncategorized

We know we aren’t the only dads who had big dreams for Halloween this year—after all, how often does the spooky holiday actually fall on a weekend? And one that coincides with a super rare blue moon, no less! Our kids have had their costumes picked out since last October, and we were fully prepared to endure 48-hour sugar highs and demand extra candy tax in compensation. Of course, no one could have predicted a global pandemic would throw a wrench into those plans, leaving many of us scratching our heads as to how to make a highly anticipated event...

To the Great-Grandparents: Thank You For Loving Us So Well

In: Uncategorized

Can we take a minute to talk about the blessing of great-grandparents? Grandparents (i.e. your own parents) spoil your kids, of course—it’s a time-honored tradition, really. The reward for surviving parenthood with your own children is spoiling your grandchildren with abandon. All that spoiling prompts the inevitable wondering, “Where were these people when they were raising me?!” Your parents limited television and junk food. They enforced rules and consequences. Who are these pod-people who’ve invaded your parents’ bodies and are now spoiling the living daylights out of your children? This question doesn’t exist where great-grandparents are concerned. You know exactly...

I Want My Son To Take Pride in His Heritage

I don’t know how many times I’ve been asked the same question, THE question. The one I have grown accustomed to hearing yet not grown accustomed to answering. “What are you?” I’ve been asked this by people I’ve known for months and people I have known for mere seconds.  As a child, I had my prepared answer, “I am Polish, German and Native American.” Not the full story. As an adult I’ve tested out different responses, “I am American; I am mixed.” Not the answer they want to hear.  The truth is I was ashamed. Ashamed as a young child...

Hello average and below average kids and teenagers! Today you will not be on a stage receiving an honor, a pin, a certificate, a sash, a cord, or a badge for high academic achievement. Nobody will tell you your future is bright and positive, or that you can do and be anything you want. You will shuffle along the rest of your school days and years sheepishly wearing the “average” badge—which is actually no badge at all, rather it’s just you sitting small watching everyone else standing tall with honor. But I want to tell you something. Something incredible. It’s...

I'm Not a Princess - But I'm Raising One www.herviewfromhome.com

It was at my baby shower that I received my daughter’s first princess tiara. It was a gift from a family friend and it was truly beautiful. Radiantly adorned with Swarovski crystals and perfectly sized to fit atop a tiny toddler’s head. I remember my mom gushing over it when I unwrapped the box after the party was over. I scowled at it. “She will not wear that thing,” I said. My mom looked confused. “But she’s going to be a little girl. Of course she will want to wear it!” she said. “My daughter will never be called a...
