Re-sizing Images for Projection

Guidelines for the Preparation of Images for Projected Digital Image (PDI) Competitions

FCC uses an Epson HBMI Projector with a resolution of 1920 x 1080 pixels for its PDI Competitions, This projection equipment gives the most accurate representation of digital images in terms of colour, tone, fine detail and image sharpness.

In order to display your images in the most optimum way and to ensure that they are projected correctly, it is important to follow these guidelines exactly for the preparation of your digital files, and failure to configure the files correctly may result in poor reproduction.

Please note that these guidelines are designed principally for PC users who use any of 3 popular image processing software packages: Photoshop, PS Elements, Lightroom. For other image processing software please consult the HELP tab in your specific application or go on-line for advice/help (use the search term 'Re-sizing images' with the name of your software application). For members with MACs a different procedure may be required - please consult the HELP tab on your installed software and/or other Mac users in the Club.

For beginners, basic adjustments, e.g resizing, cropping, cloning, colour, levels adjustments etc can be made in a free software programme called Faststone.

Detailed Guidelines

Projection Colour Space: sRGB has been adopted as the standard. Other colour spaces (e.g. Adobe RGB) will either be converted, possibly resulting in 'false colouration' and a poor projected image.

Re-sizing your images to the required size.

File Image Format:

Finalised images should be saved in the highest possible JPEG quality and submitted as JPEG files (filename.jpg). NB other file formats such as .tif, .psd, RAW formats etc will not be recognised. The maximum file size is 200 mb.

It is strongly recommended that your competition entries be saved in a separate folder (e.g. on your Desktop or a place of your choice) to avoid the possibility of overwriting your original images with the considerably smaller and lower quality PDI files. Also if you are chosen to represent the club at County or National level your images may need to be resized and you may need the original.

Image Labelling:

Just the image title, the upload does the rest.

Entry Submission:

Entries should be submitted via the upload system by the deadline, these dates are shown in the programme and in "Manage Competitions" area on the Members area.
