There are many methods of Digital Image preparation for Projected Competitions, below are just some of them.
This is probably the most common Resizing Method for Competitions using photoshop or other similar software.
Images for Digital projected competitions should be resized (reduced) to suit the digital projector native resolution. This will make sure it is projected at the right size and allow you to see the effects of a reduced image before it is projected. For the latest projectors a size no larger than 1400 pixels in width and 1050 pixels in height is required. If your image is in portrait format then ensure that the height (the longer side) is a maximum of 1050 pixels.
Attach your images to your e-mail as jpeg files no larger than 2 MB each and name your files as ‘(image title) (Mem no.). Jpg’ this will make it easier for me to process the files. For example, “ Edinburgh Castle mem 24.jpg “.
There are two parts to this process.. Resizing.. and Saving
First part Resizing
The description below is from Photoshop, but the commands are similar in other software.
To resize an image use ‘Image>Image Size’. This will bring up the ‘Image Size’ window.
The first thing to consider is whether you need to resize your image or not. Look at the dimensions of your image in pixels and if the width is smaller than 1400 pixels and the height is less than 1050 pixels then skip resizing and go down to the bit about saving your image. An image that is too small will not fill the projector screen.
To begin with ensure that ‘Resample Image’ check box is ticked and the resampling method is bicubic .
You will want to keep your image in the same proportions as the original so ensure that the ‘Constrain Proportions’ check box is ticked.
Now set the ‘Resolution’ to 72 pixels / inch, do this first then modify the Pixel Dimensions boxes width or height until your image is smaller than the 1400×1050 pixels required. Note that by having the proportions constrained, changing the width will automatically result in a change in height and vice versa.
Now click ‘OK’.
Second part Saving
Click ‘File>Save As’ and enter the new competition file name, make sure the file name is different so you don’t over write your high resolution original.. Set the ‘Format’ in the ‘Save As’ window to JPEG. And click save.
Now a new window is presented which controls the JPEG compression options
The ‘JPEG Options’ window controls the storage size of the image. A quality setting of Maximum should be possible giving minimal compression and a good quality image, but check the file size that is just under the preview tick box and make sure it is less than 1,000.0K ie. 1MB .( now with improved broadband up to 2MB allowed)
Leave the ‘Format Options’ as ‘Baseline’ (Standard).
If the ‘Preview’ checkbox is ticked you will be able to see the effect of changing this parameter on the image.
All that is left is to attach the newly resized jpg image files to your email and send. Make sure your email package does not try to send attachment as a photo and resize it again.

Eric Begbie’s Step by step resizing using Lightroom
1. In the Library Module, highlight the image you want to export and click the “Export” button.
2. In the File Naming Section, choose “Custom Name” from the drop-down menu and enter the filename that you want. For SDCC competitions this will be your photograph title followed by your membership number, e.g. Golden Sunset 113
3. In the File Settings section (click the triangle to the left of “File Settings” if it isn’t already expanded), choose JPEG as the Format and sRGB as the colour space (which should be the default for JPEG already). Enter 2000 in the Limit File Size box to keep the file below 2MB.
4. Then in the image sizing section, choose Resize to Fit: Width & Height – W: 1400 and H: 1050 pixels. This will resize your photo to fit within a box that’s 1400 pixels wide by 1050 pixels high, which is what you want for the SDCC competitions. This will work whether your photo is in a landscape or portrait orientation. It will resample your photo to retain the same aspect ratio while decreasing the number of pixels overall to fit. Tick the “Don’t Enlarge” box. Ignore the “Resolution” box.
