Mission: Special F/X Developed by S. Wade Bradt for R.A. Reiser EME 5603 – Fall 2009 Target Audience: Chiles HS

Sec 1: Mission Background Bradt-EME5603

a camera’s Shutter Speed (SS) and Aperture (Ap) settings Mission Objectives SEC 1 2 3 4 5 The purpose of this training is to learn how to create Special Effects (SFX) using a camera’s Shutter Speed (SS) and Aperture (Ap) settings The 4 SFX can be grouped by type: 2 SFX control motion 2 SFX control what is in focus Bradt-EME5603

Mission Objectives SEC 1 2 3 4 5 The 4 SFX skills necessary for taking Mission Ops photographs are: Frozen Motion Blurred Motion Shallow Depth of Field (DOF) Deep Depth of Field (DOF) Motion SFX Focus SFX Bradt-EME5603

Mission Background SEC 1 2 3 4 5 You will learn how to use a camera’s controls to generate special effects that Headquarters has identified as Mission Critical. On the following pages, you will see examples of the 4 SFX, and how SS and Ap work together to create them. Bradt-EME5603

All objects reflect light Mission Background SEC 1 2 3 4 5 All objects reflect light The amount of light allowed into the camera by the lens affects what the photo looks like. A camera’s shutter works just like blinds on a window – they can be opened and closed. How long the shutter remains open (or how fast it moves) controls how much light is captured. Bradt-EME5603

A camera’s aperture size refers to how wide the blinds open. Mission Background SEC 1 2 3 4 5 A camera’s aperture size refers to how wide the blinds open. Just like a window, the larger the opening, the more light will enter. How wide (or narrowly) the aperture opens controls how much light is captured. Bradt-EME5603

Increasing the SS will allow the camera to capture a smaller period of time and “freeze” the motion of the subject. Bradt-EME5603

Photo courtesy of www.militaryphotos.net SEC 1 2 3 4 5 Blurred Motion Photo courtesy of www.militaryphotos.net Blurring the motion of a subject captures an image that looks like it’s moving. Decreasing the SS will allow the camera to capture a longer period of time and “blur” some of the motion of the subject. Bradt-EME5603

Photo courtesy of www.militaryphotos.net SEC 1 2 3 4 5 Shallow depth of field Photo courtesy of www.militaryphotos.net Creating a Shallow DOF emphasizes the subject in the foreground and “blows away” (or blurs) the background. Increasing the Ap size (making it wider) will result in only a narrow band of action in front of the lens that remains in focus. Bradt-EME5603

Photo courtesy of www.militaryphotos.net SEC 1 2 3 4 5 Deep Depth of Field Photo courtesy of www.militaryphotos.net Creating a Deep DOF keeps everything in focus – subjects close to the lens and subjects far away. Decreasing the Ap size (making it smaller) will result in a very deep area in front of the lens that remains in focus. Bradt-EME5603

Remember… Motion SFX Focus SFX Frozen Motion = Faster SS Blurred Motion = Slower SS Focus SFX Shallow DOF = Wider Ap Size Deep DOF = Smaller Ap Size Bradt-EME5603

Good Job! You have successfully completed Basic Training. You may proceed. Photos courtesy of www.militaryphotos.net Deep DOF: Foreground & Background in focus Blurred: Motion of subject is blurred, suggesting movement Frozen: Motion of subject is frozen Shallow DOF: Foreground in focus, Background out of focus Bradt-EME5603

Sec 2: Identifying “normal” Readings Bradt-EME5603

Establishing a baseline SEC 1 2 3 4 5 You now have a better understanding of your mission. In this section, you will learn how most cameras display their “normal” readings, and learn how to interpret those numbers. Bradt-EME5603

Establishing a baseline SEC 1 2 3 4 5 Remember, during your basic training you learned: The shutter and aperture work like blinds on a window, opening and closing to let in light. Increasing and decreasing SS will help you freeze and blur motion (the Motion SFX). Increasing and decreasing Ap will help you create Shallow and Deep depths of field (the Focus SFX). Bradt-EME5603

Understanding terminology SEC 1 2 3 4 5 Both SS and Ap settings are moved in increments called “stops.” Stops are just like a volume knob, ranging from 1 (Quiet) to 10 (LOUD!). Aperture stops show the width of the opening from 22 (Narrow) to 2.8 (WIDE). Shutter Speed stops show how fast it opens and closes, from 1 second (slow) to 1000th of a second (fast). Bradt-EME5603

Courtesy of www.photonhead.com shutter speed Basics SEC 1 2 3 4 5 Shutter Speed is displayed in numbers that represent time. Notice that the graph decreases from “more light” at the top to “less light” at the bottom. The speed of the SS increases from slow at the top to fast at the bottom. Courtesy of www.photonhead.com Bradt-EME5603

Courtesy of www.photonhead.com shutter speed Basics SEC 1 2 3 4 5 The number “1” at the top stands for 1 second. The number “1/1000” at the bottom stands for 1000th of a second. Many cameras represent those fractions in whole numbers. 1, 2, 15, 30, 60, 125, 250, 500, 1000 Courtesy of www.photonhead.com Bradt-EME5603

Letting the right amount of light through the lens results in a good looking photo. This is also called a “good exposure” because the film is exposed to the right amount of light. Too much light… Not enough light… Good “exposure” Bradt-EME5603

Courtesy of www.photonhead.com Aperture basics SEC 1 2 3 4 5 Aperture size is displayed in numbers that represent size. Notice that the graph decreases from “more light” at the top to “less light” at the bottom. The size of the Ap opening also increases from narrower at the bottom to wider at the top. Courtesy of www.photonhead.com Bradt-EME5603

Courtesy of www.photonhead.com Aperture basics SEC 1 2 3 4 5 The wider the opening, the more light. Notice that the widest setting has a lower stop number – f2.8. And the narrowest setting, the one that lets in the least amount of light has a higher stop number – f22. Courtesy of www.photonhead.com Bradt-EME5603

Courtesy of www.wordpress.com Aperture basics Hi, my name’s “Tiny” The fact that Wider openings are controlled by Smaller setting numbers can be confusing. It may help to think of the setting numbers as being how much effort the Ap has to give to close down. Closing the Ap to f22 requires much more effort than closing it to f8. Mine’s “Big Al” Courtesy of www.wordpress.com Bradt-EME5603

Courtesy of www.synapticlight.com Practice example On the following page, you will circle the Aperture setting that is the narrowest. And, put a square around the Aperture setting that is the largest. This example shows you how to complete that exercise. Courtesy of www.synapticlight.com Bradt-EME5603

Practice Circle the Aperture setting that is the narrowest. Put a square around the Aperture setting that is the largest. Bradt-EME5603

Well Done! Remember: Wider Ap openings are represented by smaller numbers. A narrower Ap would let in less light. A wider Ap would let in more light. Bradt-EME5603

example 15 30 60 125 250 500 1000 On the following page, you will circle the fastest SS. And, put a square around the slowest SS. Then to draw an arrow showing how the SS increases and decreases. This example shows you how to complete that exercise. Slower Faster Bradt-EME5603

Circle the SS setting that is the fastest. practice Circle the SS setting that is the fastest. Put a square around the SS setting that is the slowest. 500 250 125 60 30 15 2 Bradt-EME5603

Well Done! Remember: Faster shutter speeds are represented by larger numbers. Slower shutter speeds would let in more light. Faster shutter speeds would let in less light. 500 250 125 60 30 15 2 Faster Slower Bradt-EME5603

Basic training complete SEC 1 2 3 4 5 Congratulations! You now have the basics “locked down” and are ready to proceed with the heart of the lesson. Now you’re going to learn how to use those controls together to create the 4 SFX. Keep up the good work! Bradt-EME5603

Sec 3: Using Shutter Speed Bradt-EME5603

Motion SFX are the techniques used to freeze and blur motion. Special FX SEC 1 2 3 4 5 When SS and Ap work together, one is always the Primary setting and one is the Secondary setting. In this section, you will learn how to use SS and Ap together to create “Motion SFX.” Motion SFX are the techniques used to freeze and blur motion. Bradt-EME5603

Remember, you have already learned: Special FX SEC 1 2 3 4 5 Remember, you have already learned: SS is used to freeze and blur motion. SS is based on fractions of a second. SS is usually shown in whole numbers (60, 125). SS settings are referred to as “stops.” Bradt-EME5603

SS and Ap work together to create SFX. Primary and secondary SEC 1 2 3 4 5 SS and Ap work together to create SFX. For “Motion SFX,” SS is the Primary setting and Ap is Secondary. That means for all Motion SFX, SS is adjusted 1st, and Ap is adjusted 2nd. Bradt-EME5603

Photo courtesy of www.militaryphotos.net SEC 1 2 3 4 5 Motion SFX Photo courtesy of www.militaryphotos.net Increasing SS will “freeze” motion. Increasing SS reduces the time that the “blinds” are open. But it also reduces how much light will enter the lens. Bradt-EME5603

Photo courtesy of www.militaryphotos.net SEC 1 2 3 4 5 Balancing light Photo courtesy of www.militaryphotos.net Reduced light will freeze the motion but could result in a badly exposed image (too much or too little light). Increasing Ap size when increasing SS will provide a balanced amount of light. Bradt-EME5603

Photo courtesy of www.gettyimages.net SEC 1 2 3 4 5 Motion SFX Photo courtesy of www.gettyimages.net Slowing SS will “blur” motion. Slowing SS increases the time that the “blinds” are open. But it will also increase how much light will enter the lens. Bradt-EME5603

Photo courtesy of www.corbis.com SEC 1 2 3 4 5 Balancing light Photo courtesy of www.corbis.com Increased light will blur the motion but could result in a badly exposed image (too much or too little light). Decreasing Ap size when decreasing SS will provide a balanced amount of light. Bradt-EME5603

Circle the best answer below to practice selecting your settings: In order to freeze motion, you would increase/decrease the Shutter Speed. In order to blur motion, you would increase/decrease the Shutter Speed. Bradt-EME5603

That’s Right! Good job! Let’s try some more… Your answers were correct: In order to freeze motion, you would Increase the Shutter Speed. In order to blur motion, you would Decrease the Shutter Speed. Good job! Let’s try some more… Bradt-EME5603

Circle the best answer below to practice selecting your settings: If you increase SS to freeze motion, you would increase/decrease the Ap size to compensate. If you decrease SS to blur motion, you would increase/decrease the Ap size to compensate. Bradt-EME5603

Well Done! Your answers were correct: If you increase SS to freeze motion, you would increase the Ap size to compensate. If you decrease SS to blur motion, you would decrease the Ap size to compensate. Notice the balance for each of those… Increase goes with increase and decrease goes with decrease. Bradt-EME5603

In this example, SS is on the left and Ap is on the right. Courtesy of www.photonhead.com Courtesy of www.photonhead.com In this example, SS is on the left and Ap is on the right. Notice that the graph decreases from “more light” at the top to “less light” at the bottom. Bradt-EME5603

Normal Courtesy of www.photonhead.com Courtesy of www.photonhead.com To freeze the motion of those flags fluttering in the breeze, you’d need to increase the SS as shown by the Red Arrow. However, because an increased SS will allow less light to enter the lens, the Ap needs to be made wider to compensate, as shown by the Green Arrow. Bradt-EME5603

Normal Courtesy of www.photonhead.com Courtesy of www.photonhead.com In other words, since the “blinds” will be opened for a lesser amount of time, they need to open wider during that time so that there is enough light to take a good picture. Bradt-EME5603

2 stops wider Normal 2 stops faster Courtesy of www.photonhead.com Courtesy of www.photonhead.com Remember: Every Primary adjustment needs to be balanced with an equal change to the Secondary setting. If you change SS by two stops, you need to change Ap by two stops – every change needs to match. Bradt-EME5603

Practice preparation Remember: When adjusting SS and Ap for SFX, changes should be made in an equal and balanced number of stops. If you increase SS by four stops, Ap width should be increased by four stops. Changes to SS are matched and balanced to make sure there is the right amount of light for a good exposure. Let’s give it some more practice… Bradt-EME5603

Practice Scenario: the camera’s “normal” readings are shown in the box below. If you want to freeze the motion of your subject, circle the two (2) new settings you would select. Put a number 1 by the adjustment you would make first and a number 2 by the adjustment you would make second. f22 F16 F11 F8 F5.6 F4 F2.8 Ap 500 250 125 60 30 15 2 SS Bradt-EME5603

Good Job! f22 F16 F11 F8 F5.6 F4 F2.8 2 500 250 125 60 30 15 2 1 You correctly determined that to freeze motion, you needed to make the SS faster. If 125 was the normal reading, then you would need to select either 250 or 500 as your new speed. You also remembered that SS is the Primary adjustment for Motion SFX and should be adjusted first. Did you also remember that you needed to move the Ap setting the same number of stops that you moved the SS setting? In this example, both settings were moved 2 stops. Bradt-EME5603

More Practice Scenario: the camera’s “normal” readings are shown in the box below. This time, you want to blur the motion of your subject Circle the two (2) new settings you would select. Put a number 1 by the adjustment you would make first and a number 2 by the adjustment you would make second. f22 F16 F11 F8 F5.6 F4 F2.8 Ap 500 250 125 60 30 15 2 SS Bradt-EME5603

Good Job! f22 F16 F11 F8 F5.6 F4 F2.8 2 500 250 125 60 30 15 2 1 You correctly determined that to blur motion, you needed to make the SS slower. If 125 was the normal reading, then you would need to select either 60, 30, 15 or 2 as your new speed. You also remembered that SS is the Primary adjustment for Motion SFX and should be adjusted first. Did you also remember that you needed to move the Ap setting the same number of stops that you moved the SS setting? In this example, both settings were move 3 stops. Bradt-EME5603

Sec 4: Using Aperture Bradt-EME5603

Focus SFX are the techniques used to create Shallow and Deep DOF. Special FX SEC 1 2 3 4 5 When SS and Ap work together, one is always the Primary setting and one is the Secondary setting. In this section, you will learn how to use Ap and SS together to create “Focus SFX.” Focus SFX are the techniques used to create Shallow and Deep DOF. Bradt-EME5603

Remember, you have already learned: Special FX SEC 1 2 3 4 5 Remember, you have already learned: Ap is used to create Shallow and Deep DOF. Ap is based on the width of the opening. Ap settings are shown in stops. Ap stops range from f22 (narrow) to f2.8 (WIDE). For “Motion SFX” SS is the Primary setting and Ap is the Secondary setting. Bradt-EME5603

However, for “Focus SFX,” the OPPOSITE is true Primary and secondary SEC 1 2 3 4 5 As you know, for “Motion SFX,” SS is the Primary setting and Ap is Secondary. However, for “Focus SFX,” the OPPOSITE is true For “Focus SFX,” Ap is the Primary setting and SS is Secondary. Bradt-EME5603

Photo courtesy of www.militaryphotos.net SEC 1 2 3 4 5 Focus SFX Photo courtesy of www.militaryphotos.net Increasing Ap will create Shallow DOF. Increasing Ap size increases the width that the “window blinds” are open. Increasing Ap will increase how much light will enter the lens. Bradt-EME5603

Photo courtesy of www.militaryphotos.net SEC 1 2 3 4 5 Balancing light Photo courtesy of www.militaryphotos.net Increased light will create Shallow DOF but could result in a badly exposed image. Increasing SS when increasing Ap will provide a balanced amount of light. Bradt-EME5603

Photo courtesy of www.gettyimages.net SEC 1 2 3 4 5 Focus SFX Photo courtesy of www.gettyimages.net Decreasing Ap size will create Deep DOF. Decreasing Ap size reduces the width that the “window blinds” are open. Decreasing Ap will reduce how much light will enter the lens. Bradt-EME5603

Photo courtesy of www.militaryphotos.net It may help to think of the camera lens as focusing light, just like a laser does. Photo courtesy of www.militaryphotos.net The more the light is concentrated, the farther it goes. A smaller Ap focuses the light more – deeper DOF. While a wider Ap spreads the light – shallower DOF. Bradt-EME5603

Circle the best answer below to practice selecting your settings: In order to create a Shallow Depth of Field, you would increase/decrease the Ap size. In order to create a Deep Depth of Field, you would increase/decrease the Ap size. Wider Ap size is shown by smaller/larger numbers. Smaller Ap size is shown by smaller/larger numbers. Bradt-EME5603

That’s Right! Your answers were correct: In order to create a Shallow Depth of Field, you would increase the Ap size. In order to create a Deep Depth of Field, you would decrease the Ap size. Wider Ap size is shown by smaller numbers. Smaller Ap size is shown by larger numbers. Good job! Let’s try some more… Bradt-EME5603

Circle the best answer below to practice selecting your settings: If you increase Ap size to create a Shallow DOF, you would increase/decrease the SS to compensate for the increased light. If you decrease Ap size to create a Deep DOF, you would increase/decrease the SS to compensate for the decreased light. Bradt-EME5603

Well Done! Your answers were correct: If you increase Ap size to create a Shallow DOF, you would increase the SS to compensate. If you decrease Ap size to create a Deep DOF, you would decrease the SS to compensate. Remember the balance for each of those… Increase goes with increase and decrease goes with decrease. Bradt-EME5603

Courtesy of www.photonhead.com Remember this example? Once again, SS is on the left and Ap is on the right. On the next few pages, we’ll go over what changes need to be made when you’re going for Focus SFX. Bradt-EME5603

Normal Courtesy of www.photonhead.com Courtesy of www.photonhead.com To create a Shallow DOF (focusing on those boots), you’d need to increase the Ap as shown by the Red Arrow. However, because increased Ap size will allow more light to enter the lens, SS needs to be faster to compensate, as shown by the Green Arrow. Bradt-EME5603

Normal Courtesy of www.photonhead.com Courtesy of www.photonhead.com In other words, since the “blinds” will be opened wider, it needs to open for less time so that there isn’t too much light to take a good picture. Bradt-EME5603

2 stops wider Normal 2 stops faster Courtesy of www.photonhead.com Courtesy of www.photonhead.com Remember: Every Primary adjustment needs to be balanced with an equal change to the Secondary setting. If you change Ap by three stops, you need to change SS by three stops – every change needs to match. Bradt-EME5603

Let’s give it some more practice… Practice preparation Remember: When adjusting Ap and SS for SFX, changes should be made in an equal and balanced number of stops. If you increase Ap size by one stop, SS should be increased by one stop. Changes to Ap are matched and balanced to make sure there is the right amount of light for a good exposure. Let’s give it some more practice… Bradt-EME5603

Practice Scenario: the camera’s “normal” readings are shown in the box below. If you want to create a Shallow DOF, circle the two (2) new settings you would select. Put a number 1 by the adjustment you would make first and a number 2 by the adjustment you would make second. f22 F16 F11 F8 F5.6 F4 F2.8 Ap 500 250 125 60 30 15 2 SS Bradt-EME5603

Good Job! f22 F16 F11 F8 F5.6 F4 F2.8 1 500 250 125 60 30 15 2 2 You correctly determined that to create a Shallow DOF, you needed to make the Ap wider. If f8 was the normal reading, then you would need to select either f5.6, f4 or f2.8 as your new Ap size. You also remembered that Ap is the Primary adjustment for Focus SFX and should be adjusted first. Did you also remember that you needed to move the SS setting the same number of stops that you moved the Ap setting? In this example, both settings were moved 2 stops. Bradt-EME5603

More Practice Scenario: the camera’s “normal” readings are shown in the box below. This time, you want to create a Deep DOF. Circle the two (2) new settings you would select. Put a number 1 by the adjustment you would make first and a number 2 by the adjustment you would make second. f22 F16 F11 F8 F5.6 F4 F2.8 Ap 500 250 125 60 30 15 2 SS Bradt-EME5603

Good Job! f22 F16 F11 F8 F5.6 F4 F2.8 1 500 250 125 60 30 15 2 2 You correctly determined that to create a Deep DOF, you needed to make the Ap wider. If f11 was the normal reading, then you would need to select either f16 or f22 as your new Ap size. You also remembered that Ap is the Primary adjustment for Focus SFX and should be adjusted first. Did you also remember that you needed to move the SS setting the same number of stops that you moved the Ap setting? In this example, both settings were moved 2 stops. Bradt-EME5603

Sec 5: Field Readiness Bradt-EME5603

Putting it all together… SEC 1 2 3 4 5 Well done, you now have all the pieces of knowledge that are mission critical. The short exercise in this section will ensure that you are able to assemble those “pieces” in a manner which will ensure mission success. Bradt-EME5603

You will be creating 4 SFX on your mission. Remember the mission SEC 1 2 3 4 5 You will be creating 4 SFX on your mission. Frozen Motion and Blurred Motion are called Motion FX. Shallow and Deep Depth of Field are called Focus FX. Shutter Speed (SS) and Aperture size (Ap) are the settings used to control these FX. Bradt-EME5603

Remember your basic training SEC 1 2 3 4 5 The amount of light allowed into the camera by the lens affects what the photo looks like. A camera’s shutter works just like blinds on a window – it can be opened and closed. How long it remains open, and how widely it opens, control how much light is captured in the photo. Bradt-EME5603

How it all comes together SEC 1 2 3 4 5 For Motion SFX: SS (Primary) can be increased to freeze motion or decreased to blur motion. Ap size (Secondary) must be increased or decreased in proportion in order to get a good exposure. For Focus SFX: Ap (Primary) can be increased to create a Shallow DOF or decreased to create a Deep DOF. But then SS (Secondary) must be increased or decreased a matching number of stops to compensate. Bradt-EME5603
