The Width (W) should now not exceed 1920 pixels and the Height (H) should not exceed 1200 pixels.

With the box selected hit enter to execute the image size change.

Send your entry

You must upload your EDI entries via the NCP Competition Registration and EDI Upload page so that it arrives no later than 8.00 p.m. the Sunday before the competition.


Q: I would like to make my image occupy the whole of the projected area.
A: Select the Rectangular Marquee Tool. Under Style select Fixed Aspect Ratio, in Width insert 4 and in Height select 3. Make your selection, then under Image select Crop. After the above process is followed the resulting image will be exactly 1920 x 1200 pixels.

Q: My image e.g. 1920 x 600 pixels does not occupy the whole of the screen. How does the rest of the image appear?
A: The image viewer software (Adobe Bridge) will display this area in a black colour. If you wish to have control over this you may extend the canvas size to the full 1920 x 1200 pixels and select your own fill colour.

Q: Why use the sRGB colour space?
A: The data projector supports and is calibrated for the the sRGB colour space. Provided your monitor is suitable calibrated the image should be the same on both monitor and data projector.

Q: What happens if I do not use the sRGB colour space?
A: The image will not be displayed accurately. For example Adobe sRGB colour space images will lose a lot of their punch while Apple RGB images will appear too dark.

Feedback welcome.
