Preparing Your Images for Digital

These notes are guidelines only please follow the instruction provided for specific competitions.
In most cases Image size should be 1400 x 1050 pixels (for projection at SXGA) in .tif or .jpg format at maximum quality Images will be projected onto a black background
You should use 1024 x 768 pixels (for projection at XGA)

In Adobe Photoshop or Elements

1. Resize your image to 1400 x 1050 Pixels or (1024 x 768)

a) FILE > OPEN click on your chosen file and click ‘Open’
Remember if you have done work in layers in Photoshop you should ‘flatten’ your image before resizing: LAYER > FLATTEN

b) IMAGE > MODE > RGB select 'Colour' & '8 Bits'
(In Elements - if you are not prompted on opening, convert to 8 bits)

and tick the boxes - ‘Constrain Proportions’ and ‘Resample Image’
un-tick the box 'Scale Styles' and choose one of the ‘Bicubic’ options
(if you are not sure then just select ‘Bicubic’)
(Note: Older versions of Photoshop only have two boxes, tick both of these and carry on as above)

d) Still in the image size palette, you require to set the Pixel Dimensions:
If a ‘landscape’ (horizontal image) in ‘Pixel Dimensions’ > WIDTH >
type 1400 or ‘1024’ (the height will be automatically filled in)
or If a ‘Portrait’ (vertical image) in ‘Pixel Dimensions’ > HEIGHT > type
1050 or ‘768’ (the width will be automatically filled in) and left mouse click ‘OK’

2. Resize your canvas to 1400 x 1050 Pixels or (1024 x 768)

Un-tick 'Relative' box and set 'Canvas Extension Colour' to 'Black
Always set the width to 1400 or 1024 pixels the height will be automatically filled in
Click on centre box of 'Anchor' and click 'OK'
You will now have your image on a black background, a portrait image will be displayed with a black edge on either side of your image. Repeat the process for other images

You can only do a basic conversion in Elements, you will not be able to do all of the above – you will find your settings in Edit ? Colour Settings, and if the file you are opening does not have a profile you will get a message coming up, (you can select sRGB here)
