Resolution Information:

The following chart from B & H Photo gives approximations of ideal sizes of pictures for print as determined by the number of pixels a camera has.

 

 

The following chart from B & H Photo compares resolution to picture size.

Common File Types:

*                      JPEG

o       Most Common

o       Smallest Files

o       Caution-Do not save over and over

 

*                      TIFF

o       Larger Files

o       Capable of Editing

 

Zoom Information:

 

*          Optical zoom actually moves you closer to the subject without sacrificing quality.

 

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

 

*          Pay more attention to Optical Zoom because it will give you the results that you want.

Memory Card Information:

 

Memory cards are removable devices used in digital cameras to store the images captured by the camera. There are several different types of memory cards available including Secure Digital (SD), XD, Mini-SD, Compact Flash, SmartMedia, and Memory Sticks. The following chart from B & H Photo is a reference point for how many images a memory card can hold using the highest resolution and lowest compression settings:

 

 

 

Picture Taking Tips

1.     Take pictures at eye level when photographing a person

2.     Use plain and simple backgrounds

3.     Use a flash outside, especially if the sun is bright

4.     Zoom in on the subject matter, you want it to fill the frame

5.     Make sure your light source isn’t behind the subject, unless you want a silhouette effect

 

The Rule of Thirds

Instead of the focal point of your picture being in the very center, move it over to where the lines intersect and the picture will be a little more interesting.  If you are taking a picture of the horizon, you want the horizontal line of the horizon to be on the line between the top two 3rds, or the bottom two 3rds. For more on the rule of thirds and other composition tips, click here.

Digital Photography PRactice: Time for a Little Fun

Digital Charades:

1)     Divide into teams of 3-5.

2)     Go to an area of the school where none of the other teams can see you.

3)     Each member will select a book, movie, TV Show, etc. to stage. (Use props if necessary.)

4)     Each member will take a photo of the other members acting out the selection.

5)     Practice using good picture taking techniques.

6)     You will have 10 minutes to complete the activity, & we will play a game when you return.

 

Connecting to the computer

1)     Most cameras come with software. It is good practice to install the software before connecting your camera to the computer.

2)     If you have Windows XP, most cameras can be connected without installing the software. The camera’s memory card will function as a flash/USB drive.

3)     You can also use a card reader which will also make the memory card function as a flash/USB drive.

4)     Caution: You may have to change the drive letter if your camera is not recognized!
