Send your entry

You must email your entry to the NCP competition email address so that it arrives no later than 8.00 p.m. the Sunday before the competition. If you do not know the email address then you will find it in the footnote of club emails. You may also contact the Webmaster. Save the address in your contacts.

FAQ

Q: I do not trust email to reliably send my images.
A: An acknowledgement that your email/entries were received will be sent but this is only of value if you send in your entries reasonably early. The NCP mailbox has a storage capacity of 15GB. Emailing one image attachment at a time may improve reliability of transmission.

Q: What happens to the images after the competition?
A: The images are stored on the Webserver for possible selection in the FCC Interclub and end of year Top Shot. They are then deleted.

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 1080 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 1080 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.
