Photo Friday: Aperture

Posted on 13 April 2012 by BrandonQ

Aperture

Overview:

Last time we talked about the shutter speed on your camera. I want to focus on aperture this week.

Aperture

Did you know that the human eye works like the aperture on a camera lens? If you were in a dark cave, your pupils would get bigger to try and let more light in. When you are outside on a sunny day, your pupils get smaller because of the amount of light coming in. Aperture is referred to the lens diaphragm opening inside a photographic lens. The size of the diaphragm opening in a camera lens REGULATES amount of light passes through onto the film inside the camera the moment when the shutter curtain in camera opens during an exposure process. The size of an aperture in a lens can either be a fixed or the most popular form in an adjustable type (like an SLR camera). Aperture size is usually calibrated in f-numbers or f-stops. i.e. those little numbers engraved on the lens barrel like f22 (f/22),f16 (f/16), f/11, f/8.0, f/5.6, f/4.0, f/2.8, f/2.0, f/1.8 etc.

Aperture affects the image in two ways. The first is the relationship to shutter speed. The smaller the aperture (large number), the longer the shutter speed needs to be. This can create blur in a photo. The best use of this is when trying to make a stream look like lace (small aperture, long shutter speed). If you would like to stop motion then use a large aperture (small number) and a faster shutter speed.

The second way aperture affects the photo is the depth of field – the area of a photo which appears in focus. A small aperture (like f/16) has a very large depth of field. The foreground and background will appear in focus. This is helpful for landscape photographs. A large aperture (like f/2.8) will have a shallow depth of field. This allows the subject to be separated visually from the out of focus background or foreground.

The images below shows how a small aperture works, (what is in focus?):

If you look at what is in focus on this photo, you see that the leaves and the dew drops are in focus when the background in not in focus.

Taking a look at Buster, his head is in focus when the rest of his body is not.

What is Aperture?

Lets put this as  simple as possible– Aperture is ‘the size of the opening in the lens when a picture is taken, this helps regulate the amount of light let onto the sensor.

Photo Friday: What is this for?

Posted on 09 March 2012 by BrandonQ

Photo Friday
Photo Fridays are brought to you by Brandon Queen Photography.

What is it and how does it all work?

Overview:

Now we want to learn about three important functions of a digital camera.  They are shutter speed, aperture, and ISO. Each of these settings act together to determine how bright or dark your photo is, or exposure. Think of them as a triangle and the foundation of exposure. Having knowledge of these functions can help you creating stunning photos!

Shutter Speed

The shutter speed is simply the length of time that the light hits the film or sensor allowing the image to be recorded. Each variation in speed (much the same as the aperture variations) is known as a “stop.” A faster shutter speed gives less more time to hit the sensor. A slower shutter speed gives light more time. Slower shutter speeds can create blurry or noisy photos but can capture images in low light. Faster shutter speeds have the ability to freeze time, but require a lot of light to be useful.

Aperture

The aperture is like the iris of the eye. When the aperture is very small, you will get a sharper focus and more depth of field– near and far things in the scene will tend to be sharper. This is because the smaller circle is cutting down on the “confusion” caused by the countless overlapping circles of light being focused on the film or other light sensitive surface in the camera. The down side is that because the iris is smaller, less light is getting to the sensor, and you need a longer exposure to get a good image. When the aperture is larger, you can get a good image with a faster shutter speed, but sharpness and depth of field may suffer a little. The “circles of confusion” are larger, because the  aperture is larger.

ISO

 

In very basic terms, ISO is the level of sensitivity of your camera to available light. The lower the ISO number, the less sensitive it is to the light, while a higher ISO number increases the sensitivity of your camera. The component within your camera that can change sensitivity is called “image sensor” or simply “sensor”. It is the most important (and most expensive) part of a camera and it is responsible for gathering light and transforming it into an image. With increased sensitivity, your camera sensor can capture images in low-light environments without having to use a flash. But higher sensitivity comes at an expense – it adds grain or “noise” to the pictures.

White Balance

White balance is not part of the “triangle” but has a big impact on your picture. It is basically a way to “measure” the temperature (color) of light and to “balance” out the colors of your photography for the desired results.

Ideally, the goal of a conventional photograph is to attain an ideal White Balance where the white color is as close to true, neutral white as possible and all of the colors in your image are “true to life.”

ISO is set to 100 which is good for out door shots on a sunny and part cloudy day.

In Focus Flower: Notice how the flower is in focus and the background is extremely blurred out. That is due to a large aperture.

A small aperture allows for a large depth of field. Notice most of the flowers appear in focus.

Photo Fridays: Proper Positioning Techniques

Posted on 17 February 2012 by BrandonQ

Photo Friday
We recognize that our audience has an interest in photography to capture special moments such as Courts of Honors, campouts, winter activities, family vacations, sport events, and other gatherings. “Photo Friday” is intended to help photography amateurs improve their photo shoots through photo tips, which may include basic skills, creative shooting techniques, and proper care and maintenance. Tips in this section are written by amateurs, professional photographers, and by other contributors. We hope that you find these tips useful in your Scouting program. Photo Fridays are brought to you by Brandon Queen Photography.

Proper Positioning Techniques

Overview:

We talked about choosing the right cameras on last weeks tip. Now we will talk about proper positioning techniques:

  • How to hold your camera properly
  • How to stand when holding your camera
  • Hand placement on the camera.

Holding Your Camera

Anyone can pick up a camera and take a photograph. We want to do it the proper way so that your pictures can be crisp and clear. All cameras are different. We are going to focus on the point and shoot cameras. You to can shoot like a pro!

Step One: Most point and shoot cameras come with a wrist strap. Therefore the strap goes on you right wrist.

If you ever get bumped, your camera should be safe with the strap.

Step Two: Your thumb should rest gently on the back of the camera.

Your right thumb should rest near the buttons. It also gives you comfort when holding your camera

Step Three: The rest of your finger should rest on the side of the lens.

The rest of your fingers should rest on the side of the lens.

Step Four: Your index finger should be free so it can access the shutter button.

Your index (pointer) finger should be the finger on the shutter button.

Step Five:Your left hand should be a brace to hold the camera in a sturdy position.

Now once you have practiced these techniques, you must keep your elbows tucked in your side (ribs) to keep your camera still. This prevents camera shake.

 

Standing Positions

  • Your feet should be flat on the ground and one slightly ahead of one another. There are may standing positions that you can use to take a photograph. One is the one knee position. This position is used to “Get on their Level”, which mean that you are at the hight of the subject. We will cover that in the upcoming tips.

    Standing photo position allows you to stand up and take a photo. This is just one of the photo standing positions.


Remember that your elbows should be planted into your side to help with stabilization. Holding the camera at arms length will result in shaky photos.
