Image resizing for KodaRoamers, PSA and CICCA


Images submitted for digital competitions need to be sized to within one of two maximum dimensions, depending on the contest.
Some competitions, such as PSA, have a maximum pixel size of 1024 x 768 while others, including CICCA, have a maximum size of 1400 x 1050.
That means the image pixel width cannot exceed the first number, and the pixel height cannot exceed the second number.
 
Most image editing programs (Paint, Lightroom, Photoshop, etc) have similar methods for resizing images. 
 Here’s a way to resize an image to 1400 x 1050 using Paint:
 
Open the image in Paint and select  <Resize>  in the menu bar.



In the drop down menu select  <Pixels>  and we see the current pixel dimensions of the image (4939).


Entering ‘1400’ as the horizontal dimension returns a vertical dimension of 1050 pixels, which is within the 1400 x 1050 pixel limits. 

Make sure the ‘Maintain aspect ratio’ box is checked to keep the correct proportions of your image.

Select ‘OK’ and the image is now sized 1400 x 1050.

The previous image happened to have a 4:3 aspect ratio, which is what both 1400 x 1050 and 1024 x 768 are.
You are not required to use that aspect ratio, you are only required to not exceed the maximum pixel limits horizontally and vertically.

 

Below is a way to resize an image for 1024 x 768 competitions:

Select  <Resize>  then  <Pixels>  and we see the image is 3000 x 2400 pixels.
 

On the left we entered ‘1024’ for the horizontal dimension and see the height change to ‘819’ which exceeds the allowed vertical dimension.

Changing the vertical pixels to ‘768’ gives us a horizontal dimension of 960, which is within the allowed width of 1024 pixels.

Select ‘OK’ and save the image with a 960 x 768 pixel size.

In some programs the resizing menus may found under ‘Image’ or ‘Image Size’

 A copy of this tutorial in MS Word is attached below.

 

Things to keep in mind when working with digital images:


Work on a copy of the original image (so you don’t alter the original ‘negative’)

Do any adjustments to the image (brightness, contrast, whatever) first.

Resize the image last to within the competition requirements.
