Preparing & Sizing your Electronic File Images           HELP PAGE 1  CCI

File dimensions:

Computer monitors and electronic projectors use a rectangular window.
Therefore, we have a difference in the maximum horizontal and vertical dimensions.
Traditional 35mm slide projectors have a square window and can project
a horizontal or vertical composition image with the same dimensions.
The equipment used for judging this Exhibition Salon uses 1024 X 768 resolution.
The image must fit into this window. (1024 X 768)

The horizontal dimension must not be greater that 1024 pixels.
The vertical dimension must not be greater than 768 pixels.

Smaller images are acceptable.
The images will be projected as received

 Use this procedure for scanned slides or prints, or images from a Digital Camera.

 In Photoshop or your favorite Image Editing Software:

1.  Crop your image for best composition.


            a. Make sure constrain proportions is checked

            b. Make sure resample image is checked

            c. For Horizontal composition photographs:

                      Set width to1024 pixels or smaller.
                     Height will automatically adjust to the correct proportion.
                     Images that were scanned from 35mm film will have a 3:2 ratio.
                     In this case the vertical dimension will adjust to 2/3 of the horizontal size.
                     For images that are cropped to other ratios, the height may
                     exceed 768 pixels after adjusting the width to 1024 pixels.
                     In this case the height must be adjusted to 768 pixels or less.
                     The width will automatically adjust itself to keep the same proportion.

            d. Square composition images:

                    As we continue to crop the width of a horizontal composition image,
                     it will eventually reach a point where the width equals the height.
                    The same holds true if we crop a vertical composition image until
                    it reaches a point where the height equals the width. (we have a square image).
                    The image must fit into this window (1024 X 768).

            e. For Vertical composition photographs:

                      Set height to 768 pixels or smaller.
                      Width will automatically adjust to correct proportion.


3.  After you size your files, you can name and save them, using the following method:

Choose:   FILE>SAVE AS  (For Photoshop Users, select FILE<Save For Web>)
             (Use this procedure for each of your images)

Use a JPEG quality of 70-80 %  (For Photoshop Users, Select: FILE<Save For Web>)
Please keep your JPEG image size under 350 Kb.

Test Image:
The Test Image shows the three RGB color strips and a Grayscale.

Use this test image to verify that your monitor is calibrated.  The best way to view this test
image is to right click on it (control click on a Mac) and save it to your
hard disk. Then open it with Photoshop (or another image editing program)
and view it at 100% at full screen. 
The test image should show 21 different shades of black/gray/white. The 0%
gray rectangle should be black. The 5% rectangle should be slightly lighter
than black.  The 100% gray rectangle should be pure white. The 95% gray
rectangle should be slighly darker than white.The Adobe Gamma control panel
is the best method to adjust a phosphor tube monitor. We will be using a gamma of 2.2.
 The Adobe Gamma control panel is included with full versions
of Photoshop. If you do not have the Adobe Gamma control panel, manually
adjust the brightness and contrast on your monitor until the test image
looks best.   For Photoshop Users, set your Color Profile to sRGB.
