Welcome to Parkland School District Digital Camera Workshop
Using a Digital Camera Choosing the Digital Camera right for you! How are you going to use the camera? How many mega pixels? How much optical zoom? What size camera fits your life style? What does a complete package include?
How are you going to use the camera? Step 1: decide how you're going to use the camera Simple Fully Automatic Small Digital SLR (single lens reflex) camera Full manual controls as well as an automatic mode Flexibility to experiment Combination Automatic and Manual
Why Use a Digital Camera? Instant gratification. No more waiting for film to be developed! (convenience)
The view screen allows you to see the picture immediately and decide if you need to take another shot. You can take multiple shots of the same thing. Delete the “bad photos”. You no longer need to pay for blurry, unfocused, closed eyes or headless shots. No More Bad Photos !
Be Creative! You have the opportunity to do more than just look at photos. Use scrap booking skills to electronically create photo album pages. Make calendars, personalized cards, invitations,posters, etc. Manipulate and alter the images.
How many mega pixels? Pixels, or "picture elements," are the dots that make up the digital images. The number of megapixels that a camera has refers to the product of horizontal pixels multiplied by vertical pixels. FALSE: more megapixels camera have higher quality images megapixels only refer to the size of an image.
Resolution The amount of detail that the camera can capture is called the resolution, and it is measured in pixels. Resolution is measured in pixels (little dots). The higher the resolution, the more dots per inch. Mega pixels refers to how many millions of pixels (or dots)the camera can produce. A number such as 1280x 960 shows how many pixels are used to make up an image.
How much zoom? Digital and Optical? Look for a higher Optical Zoom Digital zoom electronically magnifies the image-not as clear a photo.
What size camera fits your life style? Bigger is not necessarily better! Small pocket size camera carry a punch! Cameras with some weight may be more sturdy. SLR camera with large optical zooms are generally bigger, and take a larger body to support the necessary lenses.
What does a complete package include? Along with the camera you’ll need: Memory Card – SD (secure digital) cards and compact flash cards are the most common memory card types. Older camera models use other types of memory cards, such as XD cards; however secure digital and compact flash are the new industry standard.
The number of megapixels a camera has directly affects the number of images a memory card can hold. For example, an 8 GB memory card used in a 10-megapixel camera will hold 3,080 photos. If the same memory card is used in a 20-megapixel camera, it will hold 1,540 photos. Megapixel vs. Memory Card
Batteries You’ll also need: Batteries – Digital camera use a lot of power, So get rechargeable batteries. Remember: Get an extra battery so you’re not waiting around for the battery to charge.
Batteries - Here are some things to consider : Standard-size rechargeable batteries (e.g., AA), or special rechargeable batteries – Compare prices If the camera takes AA batteries, can you use normal alkaline batteries in a pinch? Are the rechargeable batteries removable, or are they permanently mounted in the camera? If they are not removable, it means that once the batteries go dead you can't use the camera again until you can get to a recharger and power supply. This can be a major pain in the neck if you want to take a lot of pictures at once.
Do you need a photo printer? Paper? Ink? Stock up on Printing Material
We’re almost ready to start shooting! Set your IMAGE SIZE When taking pictures, you need to think of how you are going to use them in the future. This way you can decide on the image quality that you will need later on. Read over the digital camera manual for information regarding that specific camera's minimum and maximum digital image file size and resolution. Most cameras are pre-set at the highest resolution the camera offers. Post on Web Print
Please remember that pictures can always be made smaller. They cannot be made larger. To the left is an example of a picture that was small and tried to be used as a larger image.
Web and If you are planning to do nothing more than display images on a Web page or send them in , then using 640x480 resolution has several advantages: Your camera's memory will hold more images at this low resolution than at higher resolutions. It will take less time to move the images from the camera to your computer. The images will take up less space on your computer.
Taking Award Winning Photos
Problems #1 – Red-eye What causes it When you take photos in a dim or dark setting, the light from your camera’s flash reflects off the subject's eyes. The resulting red glow (red-eye) is the blood vessels illuminated within the subject's retinas. How to prevent it Avoid using your flash whenever possible. (If you're not sure, take a few test shots with flash and without to see whether you absolutely need it.) If you have to use your flash, ask your subject not to look directly into the camera lens.
Problem #2 Lack of a Focal Point What causes it 1.Shooting your subject against a busy or competing background or foreground. 2.Trying to fit too much into one picture. 3.Taking a photo from far away, making your subject too small to be an obvious focal point. How to prevent it 1.Physically move closer to your subject. 2.Use your camera's zoom feature. 3.Before you snap your shot, ask yourself: "What is the main subject of this photo?" and "Does my subject fill the frame?"
Make sure your subject is large enough in the frame.
Composing the Picture Follow the rule of Intersecting 3rds Put your subject or area of interest near the intersection of thirds
Focus on the subject Focus mechanism is in the center of the camera Point the center on the subject and press ½ way down on shutter button Hold shutter button and then readjust where the subject is in the frame
Problem #3 Blur What causes it 1.A camera moving 2.Insufficient lighting. How to prevent it 1.Use a tripod or brace yourself against a stationary 2.See if your camera offers an Action mode for automatic shutter speed adjustment, or a Night or Night Portrait mode to help with low lighting. (A tripod is usually necessary for these modes due to the 3. extended exposure times.)
Holding the Camera Always hold the camera with both hands Support the camera under the Len or bottom
Problem #4 Underexposed Photos What causes it 1.Shooting in a dimly lit space. 2.Standing too far away from your subject. 3.Setting your camera's shutter speed (the length of time the shutter stays open) too fast. How to prevent it 1.If you're shooting indoors, move near a window or lamp to add extra light. 2.Move closer to your subject. 3.Manually adjust the shutter speed on 4.your camera so that it's slower.
Problem #5 – Overexposed Photos What causes it The main cause of overexposed photos is bright light, whether it’s indoor lighting or natural sunlight. How to prevent it If you're shooting on a sunny day, look for a shady spot for your subject. Use a flash to help even out the lighting and avoid severe shadows. If possible, take advantage of overcast days—they’re ideal for outdoor photography.
Don’t always shoot horizontal Horizontal is the way are brain sees things naturally Horizontal emphasizes panoramic sense Vertical emphasizes height.
Let’s take a look at our cameras Adjust the settings on your camera Setting capture resolution How to adjust the color balance Reviewing Camera Functions
Before you Start… Before You Start.... Once the power is turned on, it is then possible to adjust the settings on the camera. When you purchase a digital camera, the factory settings will most likely be designated to the most basic, or Automatic modes. Although this allows you to start taking pictures right away, you may eventually want to customize these settings to optimize your image results.
What is a Camera Mode? Modes are preset ISO/ S hutter(speed), exposure(depth of field), focus, A perture and flash combinations. The mode you choose will give priority to the setting. All cameras have slightly different mode selections. Let’s open our operator’s manual for descriptions of mode choices. Auto Scene Program A - Aperture S - Shutter M - Manual C - Custom Video
Scene is a popular choice among Beginner Photographers! Digital cameras can have a variety of modes, which are optimized for specific scenes and automatically select focus and exposure.
Lets take a look in your owner’s manual…
Here’s an example of Landscape! For distant scenery.
You may even have a mode called Flower! For Close-Ups in Bright Sunlight.
ISO ? The term ISO (or ASA) is used to measure the speed of photographic film. The higher the ISO rating the faster the film is, and fast film affords better exposures in low light situations. When in doubt, keep the ISO set to 100 (its lowest) as this renders the best image quality.
White Balance Since different sources of light vary in color temperature, it is necessary for a digital camera to have variable color capture settings. In a digital camera, you can either choose specific ratings or you can leave it on the AUTO setting (AUTO enables the camera to make its own interpreted setting.)
The LCD Screen allows you to see a large view of your intended subject. Very useful for close-ups. Images can be examined and the “bad photos” can be deleted. What appears on your LCD Screen?
Downloading When you want to import the images onto your computer, there are a couple of ways to do it. Connect a PC serial cable from the camera directly to the serial port of the computer Connect a USB card reader/writer to any of the computer's USB ports.
How do we take pictures off the camera? Direct connection to your computer Card Reader Printer Docks Directly to Printer
Images can be transferred faster to the computer. Camera is not tied up in order to transfer images. Camera battery is not being drained. Flash Path Adapters work with a computer floppy disk drive. Card Readers
Let’s take some pictures! Take the next 10 minutes to walk around the school and take some pictures. Try out different settings and zooms. Pick a variety of subjects to shoot.
Now it’s time to edit our Photos Brightness and Contrast Adjust color Crop Remove red eye Rotate or Flip and so much more!!!
Photo editing made fun Use advanced controls to fine-tune your results Crop, resize, and rotate in real-time Try out some special effects Go to the internet, and type in this address.
Red eye removal Allows you to remove the red from your picture subjects' eyes caused by the camera's flash. You can use this feature to correct red eyes wherever they appear.
Red eye removal Before And After
BRIGHTNESS AND CONTRAST Allows you to adjust the difference between light and dark tones. You can use this feature to correct pictures that appear too light or too dark.
Brightness and Contrast BeforeAfter
Color Allows you to adjust the color HUE: A color's hue is also its name. SATURATION: A measure of purity in a color. More gray in a color means lower saturation; less gray in a color means higher saturation. You can use this feature to correct pictures with colors that are tinted or dull.
Crop Allows you to crop, To trim vertical or horizontal edges of an object. Pictures are often cropped to focus attention on a particular area. Crop out unwanted parts of a picture. You can use this feature to correct pictures that contain distracting elements.
Rotate and Flip Allows you to rotate pictures or flip them on the current axis of the picture. You can use this feature to correct pictures that you have taken sideways for a portrait orientation.
Rotate and Flip
Your Photos are perfect, and ready be: Saved Printed ed Or maybe use the photo in a project. Let’s try a exercise using your edited photos.
Many Choices to store your photos! Compact Flash Memory Stick/Flash Drive CD Rom Memory Card Secure Digital Portable HD
Images take up a lot of space on your computer. Hard drive needs to be large to accommodate a lot of photos. Burn the images onto a CD Rom for storage Don’t forget to label it! Images can be burned onto disks almost anywhere that processes film. Keep in mind… Where do you store your images?
Printing Photos Printing at home cost around $.49. This is not including the cost of the printer. If your printer is not capable of good quality prints it doesn’t matter how high your camera resolution is set. The print will be of poor quality. Kiosk are available in many stores, Images can be uploaded to Internet Printing services. Printing can be done at commercial establishments.
Printing Digital Photo Prints Store prints in an album: They will last longer than framed photos. Don’t use albums with self- stick "magnetic" pages. Slip the prints you want to display in frames under glass (preferably with an anti-UV coating). Don't leave them exposed to open air. Put an acid-free mat between the frame and the photo to prevent your prints from sticking to the glass or plastic over time. Keep prints out of direct sunlight and humid rooms (bathrooms and basements), and away from intense heat (don't keep them in attics or kitchens).
