b-Resolution Informa= tion:

Digital camera resolution is measured in Megapixels.

3D"MCj0404017=

1 Megapixel is made of = one million pixels/dots.

The following chart gives approximations of IDEAL print s= izes for pictures as determined by the number of pixels a camera has.=

Megapixels	Print Size
3	5 x 7
4	8 x 10
5	11 x 14
6-10	Up to Poster Size

For a more detailed chart= , see this digital camera resolution guide which includes video display suggestions:   http://www.bhphotovideo.com/FrameWork/charts/resolutionC= hartPopup.html

C-Zoom Information: =

      =     Optical zoom actually moves you close= r to the subject without sacrificing quality.

<= /b>

      =     Digital zoom crops and enlarges the i= mage, sacrificing the quality of the image.
     (Use the software instead!)

<= /b>

      =     Pay more attention to Opt= ical Zoom because it will give you the results that you want.

      =     Most digital photography = guides do not recommend using digital zoom at all.

      =     Another example can be fo= und on page 4 of Using Your Digital Camera= .

Here’s a great reso= urce for more information on zoom, pixels, and file types: www.photo.n= et/equipment/digital/basics/

D-Shutter Informatio= n:

      =     Shutter Lag-This is the d= elay that is common with many digital cameras.

      =     Tip to reduce the lag tim= e:

<= span style=3D'mso-list:Ignore'>o&nb= sp; “First, depress the shutter release halfway to lock your auto focus and exposure settings. Then depress the shutter the rest of the way. This technique reduces the time de= lay of the actual exposure to an absolute minimum.”

E-Flash:

      =     Auto

      =     Red-Eye Reduction

      =     Flash On

      =     No Flash

      =     Fill Flash

Activity 1-Getting Acquainted with your camera

1)    After a brief overview of= how to use the zoom and set the flash on the workshop cameras, you and a partner will have the opportunity to practice using these functions.

2)    You will also be exposed = to a sample classroom activity during the process. This activity is called 10 Things (S= ee 10 Things Handout). Each partner gets to take 5 photos.

3)    As you are taking the pho= tos, please remember to take some pictures using the autoflash, some using red-e= ye reduction, some using the flash off, and some using the flash on so that you will notice the difference. Also zoom in for some photos and out for others= .

4)    Printable 10 Thin= gs Activity

F-Common File format= s:

      =     JPEG

o   Most Common

o   Smallest Files-Highly Com= pressed

o   Caution-Do not save over = and over-Quality will be lost.

      =     TIFF or RAW

o   Larger Files

o   Capable of Editing

o   Usually found on Advanced Cameras-Used by Professionals

G-Memory Card Inform= ation:

      =     Memory cards are removable devices used in digital cameras to store the images captured
     by the cam= era. There are several different types of memory cards available including Secur= e
     Digital (S= D), XD, Mini-SD, XD, Compact Flash, and Memory Sticks.

      =     Memory card speed = does make a difference in shooting speed because the camera can write
     to the car= d and perform downloads faster if the card is high-speed.

      =     Card Readers <= span style=3D'font-family:"Trebuchet MS","sans-serif"'>are useful tools for transferring photos from your card to your computer.
     (I have a c= ouple of examples if you would like to see them during the break.)

H-Battery informatio= n:

      =     Alkaline: Normal everyday batteries; easy to find; drain quickly with digital photo use

      =     NiMH: Rechargeable AA or = AAA batteries; highly recommended for digital photo use

      =     Lithium-Ion: Battery pack= s; Decent choice; Some are excellent & some die fast
