Digital Image Specifications 2013

As of the start of 2013, APS changed the specifications for digital entries from 1280 pixels on the longest edge to 1920 wide and 1080 high. The reason for the change was to be in alignment with PSNZ, plus take advantage of the improved specs of the new laptop/projector combination.

Last month, over half of the digital entries had either one or both sides exceeding these new specs, this resulted in considerable work resizing images during the nights leading up to the competition night.

What does 1920 x 1080 mean?



If your image is not in the ratio 9:16, exporting it with the longer edge correctly constrained will not necessarily mean that its shorter edge is within the 1920 x 1080 limit. You may need to specify the shorter edge as 1080 and let the export processing automatically set the long edge.

A square image should be sized 1080 x 1080.

Image size shall be no wider than 1920 pixels and no higher than 1080 pixels , sRGB and jpg at 72dpi.

The new web submission process validates the file size.

 This link is to PSNZ’s web page explaining their reasons for the change in specs and issues with out of dimension images:

In the January Focal Plane, on page 5: “Images may be smaller but must not exceed these dimensions.” This is correct, however if your image is 300×200, it will be displayed thumbnail size on a large screen. An image of this value will not be accepted. However 1000×900 is acceptable, however it is preferable to have it closer to the image specifications.


For those member who may be uncertain of the correct values within their program:

Lightroom (4.x)

Once the image has been edited as required in the Develop module, right-click the image and select Export /Export… Rename as required in File Naming and set the following values in File Settings, Image Sizing These settings can be saved as a Preset, as below.


More tips

To save these settings over your existing preset, right click the preset name and choose “Update with current settings”

The file name is no longer important as the website renames them upon receipt anyway. 


Here’s an example of where things go wrong.

The original image was 5616 x 3744. Changing the width to 1920, still results in the height being outside the 1080 specification.


 Entering 1080 for the Height, gives a correct image size with the Width being under 1920.



Similar to Photoshop. Select Image / Resample/Resize



Picasa will resize the longest edge.

  •  If you image is square: you’ll need to resize to 1080.
  • If your image is landscape: you’ll need to resize to 1920.
  • If your image is portrait: you’ll need to resize to 1080.



However, there is a catch…

You may have a high landscape image approaching a square format. Resizing to 1920, may result in the height exceeding 1080, but you won’t know. So you’ll need to check the dimensions prior to submitting you image. These are shown in the Properties Panel on the right in Picasa

If this is too complicated we have spreadsheet to calculate the value for you.

Now use the Picasa resize screen:



Other free Windows programs worth looking at are

Faststone Photo Resizer which is a resizer only. It will accept 1920×1080 as a preset and produce   the correct result with no juggling required. It can be found at: 

Paint.Net – its free and has much of the functionality found in Photoshop
