Tool Factory has been teaching digital camera workshops for 7 years. When it comes to digital cameras, I love my Olympus! is a general mantra among teachers in the training labs. Our favorite moments are those sudden bursts of discovery. For instance, when a teacher shoots a super-macro photograph of a bug's head - each of the thousand lenses in a fly's eye are suddenly visible in vibrant color. This year Olympus and Tool Factory have been working behind the scenes to develop new programs for education. Our grants program was in such high demand that we've added 20 new awards for special education. Now over $50,000 in educational grants are available for teachers, students, and special educators. But still, we wanted to do more. So we're developing a fundraising website called Digital Wish, designed to help educators acquire digital cameras and project-building software in the classroom. We've been amassing over 1,000 digital photography project ideas, all compiled in a searchable online library. Teachers will be able to hunt for interesting projects, then utilize letter-writing templates and fundraise to make their Digital Wish come true. The site will launch in early 2007 at www.digitalwish.com and we hope you will participate! Together, Olympus and Tool Factory have been working hard to create the most comprehensive digital camera program, designed just for educators. This catalog is loaded with shooting tips, budgeting ideas, and training programs to help you get started. We're committed to making a difference in education. Call the Tool Factory/Olympus team anytime at (800) 220-8386. We'll see you in the classroom. Happy Shooting! Heather Chirtea President and CEO Tool Factory, Inc.

Olympus Stylus 740

Pro SLR and Audio
With all digital cameras there can be as much as a 1+ second lag between pushing the shutter and taking a photograph. There are actually two functions of the shutter. Push the shutter halfway down and you will feel some resistance. The camera will focus on the subject and set the light level. Only after the camera has made these adjustments, will it let you push the shutter down all the way and take a photograph.

Try Again!

Let off the shutter and try again. Your camera is trying to tell you that it's going to take a bad picture. Yellow, red, or flashing lights mean bad focus or low light! Tip: Push the shutter halfway down, hold, and wait When the action happens, push the shutter all the way down. You'll get the shot every time!

Taking a Picture
How do you capture a fast action shot with a digital camera?

Shooting Modes

Program/Auto The camera automatically selects the perfect settings. Digital Image Stabilization Capture crisp, clear images free from the blur caused by camera shake and fast moving subjects. Portrait Head and shoulders shots.
Push the shutter button to take a shot. Push the playback button to view the photos you have taken. The light color indicates which mode you are in. Review your pictures in the LCD monitor. Use your tilt button to go forward and backwards through your photos in playback mode.

Mode Dial

There are common pictures every photographer will take. Depending on the environment, the camera can make some easy adjustments to automatically optimize the settings. The mode dial lets you switch between these predetermined camera settings, ensuring the best shot every time. Simply turn the mode dial to the desired settings.
Landscape For outdoor scenes at a distance. Night Scene Shoot pictures at night with a higher ISO sensitivity and faster shutter speed. Sports Capture fast moving subjects clearly. Self Portrait Point the camera toward you and shoot a picture of yourself.
SCENE Pick the perfect shooting mode for your SCN subject and situation. GUIDE

Zoom Out

Switch to playback mode and zoom out to browse thumbnails of your photos. This LCD monitor will display many thumbnails at once. Use the tilt button to navigate to the picture you want, then zoom in to bring the highlighted picture to full screen. Scroll through the pictures by pushing the left or right sides of the tilt button.
An interactive guide helps choose the appropriate settings for your situation. Movie Shoot QuickTime Movie clips. (Most models include sound).
Zoom out to see thumbnails.

Panorama Mode

Aperture Priority You pick the Aperture and the camera does the rest. Playback Look at your pictures. MY The camera remembers the photographer's special settings.

Zoom in Playback

Switch to playback mode and zoom in to the subject. If it's not in focus (or the subject's eyes are closed), simply take another shot. Select zoom and navigate around your photo using the tilt button.
The trashcan will erase unwanted pictures.

Zoom in further to check if a photo is in focus. Use the tilt button to look around a photograph you've already taken.

Playback Mode

One of the best things about digital photography is that you can see your photos as soon as you shoot them.

Shooting Tips

Composing a great photograph involves seeing the subject with your eye as well as your mind. Here are some basic composition rules to try on your own.

Leading Lines

Add depth to your photographs by capturing hard lines that travel off into the distance.

Rule of Thirds

Cut your photo into thirds and place your subject on one of the intersections of these lines. Place horizon lines on the thirds instead of straight across the middle.

Change Position

Move closer to your subjects so they fill the screen.

Perspective

Bend your knees or even lay on the ground to make the subject look larger.

Turn Camera Sideways

If your subject is vertical, turn the camera sideways so the aspect ratios match.

Foreground Interest

When shooting scenes, capturing something very close to the camera can add depth.

Self Timer

Take a class photo without a photographer! Push the shutter and run in front of the camera for group shots.

Menu Tips

Menu for Picture Taking
You can activate your menus by pressing the OK or Menu button. Your camera's menus will appear on the monitor on the back Menu for Playback of the camera. Use the tilt button to navigate directionally through the menus. *Important* There are different menus for picture taking and playback. Some cameras have different menus for every setting on the mode dial.

Changes For Satellite
Material Low CTE Needed Bearings No grease Controls
Position and Velocity: magnetometer and angular resolver Algorithm written in C code Data collection by onboard computer
Optics Tube Inner coating to prevent reflection Camera Built by LASP Motor 24V may not be available Structure No Test Bed/Support Structure All parts must be space rated

Conclusion

System and subsystem designs meet system level requirements
Combined errors within 6 pixel smear and 3 pointing
Mechanical Design is robust and within tolerances Electrical system can provide power and data paths for the entire system Software Design verified by simulation Under Budget
