10:10 Aperture

Last week you learned through practice that the easiest approach to abstract photography is the close up shot. Close-ups remove the context of what is in the viewfinder as well as emphasizes the texture and graphic elements.

We also talked about Focal Length briefly…

Focal Length is the space from the camera sensor to the lens. This measurement is measured in millimeters.

Wide Lens – 35mm
Normal Lens – 50mm
Telephoto Lens – 75-300mm

Focal Length is measured in Millimeters and it represents the distance from the center of the camera’s lens to the sensor of the camera body. The longer the distance, the longer the lens, and the longer the zoom.

Why does the Focal Length Matter? Well, focal length will help you:

Determine your Field of View. When you change the focal length, the field of view will change. More or less will show in the viewfinder. Look at the image above for an example
Perspective – Objects behind an image will be compressed with longer focal length
Depth of Field is affected by focal length
1. shallow DOF – small or narrow area is in focus
2. long DOF – more in focus

Aperture

To control focal length, let’s learn about Aperture Priority mode.

Aperture is the space through which light passes into the camera. The smaller the hole, the less light. The larger the whole, the more light.

Your Camera has an Aperture Priority Mode! Turn your camera to the AV dial.

Remember, in Aperture Priority mode, you have control over the Focal Length which is referred to as the lense field of view. Cheat Sheet

A small f-stop number (f2) means a shallow depth of field (blurred background) and large f-stop number (f22) means a large depth of field (more in focus behind the subject)

Can you think of some shooting scenarios where you would want to adjust the aperture?

Activity: Confused Yet? Let’s go outside and practice.

Set your camera up in AV Mode.

Set up the focal length of your lens to 35mm. Do not adjust.

Set up your camera to manual focus

Using the Bracketing technique (new word), find a subject and attempt to blur the background while keeping your main subject in focus. Start at your smallest f/stop and work your way to the largest f/stop.

We’ll come in and browse in Bridge and see the results.

10:50 Morning Break (10 minutes)

11:00 Shooting a Feature

*Photos courtesy of Karl Triebenbach* – TopnotchCreations

Take a look at the image above. This is my brother-in-law. He’s got a good eye for photography. He’s taken thousands of pictures of cars, motorcycles, rat bikes, places and things. He likes to fill his viewfinder with the full subject – called full frame photography. In editing he works with the color tones, shadows and highlights to improve is photos. Most often he uses a prime lens – which is a set focal distance lens. His lens of choice is 50mm – so he just walks closer if he wants to zoom.

This morning – let’s head out to the parking lot. Find a subject (item) on a car and create some full frame photography. Shoot many of the same subject – at least twelve but take a whole lot more!

This week’s Photography assignment:

Take your camera out into the world. Find an item to feature – much like you see in our demo today (bike, mailboxes, house numbers, collectibles. We should be able to tell what that feature is in ech picture and all pictures should be related.
Preview your photos and edit each one for good color, contrast, etc….
Resize each of your photos so you can fit them in a grid
You can resize using an excellent tool in Bridge – I can demonstrate
Then Assemble your photos in a grid on a 1920 by 1080px canvas.
