SLR means "Single Lens Reflex"

This means that when you look through the viewfinder of the camera, you are looking through the same lens through which light will pass to the sensor.With an SLR, if the lens cap is on everything is dark. If your hand is covering half of the lens you see it. The biggest advantage of SLRs besides seeing exactly the same image that will expose the sensor is that SLRs have interchangeable lenses. You can remove lenses and replace them with wide-angle lenses for landscape shots and telephoto for sports or wildlife. They are great for action shots.

Click on the camera for a great review of both kinds of cameras

Fixed Lens = “Point and Click"

With a fixed lens, there's a separate lens you're looking through, so you might actually have then lens cap on, or a finger over the lens and not realize it until you see the picture.

These cameras are great for stills but not as good for action shots.


The cameras our district has chosen use SD (Secure Digital) Memory Cards for storage. These are the same cards that go into many Palm products or Treo phones. They come in various sizes and prices.

Better Cameras mean LargerFiles

You want to take high resolution pictures but for web pages, e-mails, desktop publishing, and multimedia presentations you will need to resize your photos.


Resizing Photos with PowerPoint

Insert a large sized photo from the Insert Menu


Change the compression to 96 dpi

Change the size and save to the computer.


Insert the smaller photo from the Insert Menu

The original was 1,378 KB

Recompressing reduced the photo to 1,097 KB

Resizing and saving to the computer lowered the size to 163 KB

You will use far less memory in your project.


Here are a few free online photo editors


Shutterfly Studio lets you do some basic fixes

such as color, brightness, cropping, straightening


You can do a few effects like graphic poster

in a variety of colors


Using the Sepia Tone effect you can colorize

your photos with many different colors


Picassa2 from Google also offers some special effects

that will add variety to your work


You can make picture piles, contact sheets,

picture gridsand multiple exposures


Snipshot is a very basic photo editor but it is

online and you do not need to download anything


You may bring in your pictures directly from

your computer and make some basic edits


Cropping the photo is a common

action relating to photographs


Snipshot also lets you resize your photos

which is important for many creative projects


Gimp is an open source download that is about as powerful as Photoshop Elements but…

it’s FREE!!

Gimp is part of our district’s computer image.
