Preparing a Digital Image for Competition
Following L&CPU guidelines
All images in the digital competition will be in jpeg and projected in a landscape format, using sRGB colour space with a maximum size of 1400pixels wide and1050 pixels high.
Whatever the shape of the image you must “constrain proportions” but fit it within these limits. For example, a square image could be 1050x1050 pixels, a letterbox might be 1400 wide by 500 high. A “portrait” image can only be a maximum 1050 pixels high.
After resizing, if your image is less than the maximum size in either dimension the background must be filled with black or dark grey. (It may be advisable to put a narrow white border around the image if the extremes of the image are very dark, so that the image will be well seen against a dark background.) The image will then appear on screen much like a mounted print and be shown to best advantage.
ADOBE PHOTOSHOP
Open your image Then go to Image>Image size
In the Image Size dialog box ensure the “Constrain Proportions” and “Resample Image” boxes are ticked
Next change the Pixel Dimensions in either the width or height (not both) so that both numbers are within the limits :- 1400 wide and 1050 high (note that when one value is changed the other is recalculated.) The resolution in pixels/inch or pixels/cm is unimportant
Click OK
TO MAKE A BORDER
Go to Select> Select All Make sure white is your foreground colour
Go to Edit> Stroke Enter width 2 px Location inside

TO FILL UNUSED AREA WITH BLACK

Click OK The outer area is now filled with black
(NB. In Photoshop 7 you must choose your background colour before going to Image>Canvas size)
TO ENSURE YOUR IMAGE IS IN sRGB
If you have not altered the default settings in your camera or photoshop, then you will be in sRGB
