Naming and Sizing Digital Images

Any digital file submitted to the club for any purpose must be named and sized according to the guidelines below. This applies to all club activities i.e. competitions, critiques, show and tell, portfolio and annual submissions to name a few.


File Naming

All digital images submitted must be named and numbered using the following naming convention:

<Two Digit Number> <Name Surname> – <Image Title>
01 Rob Goodall – My Photo Title

For example:

Image 1: “01 Sam Jones – Big Tree”

Image 2: “02 Sam Jones – Mountain”

Image 3: “03 Sam Jones – Stream”

Image 4: “04 Sam Jones – A Great Photo”


Sizing and formatting

  • Digital images will not exceed 2Mb in size.
  • The pixel dimension shall not exceed 1920 pixels in width and 1200 pixels in height. (Note: You cannot switch these dimensions to be 1920 pixels in height and 1200 pixels in width)
  • The image resolution will be 72 pixels/inch.
  • The colour profile shall be sRGB.
  • All images must be saved/presented in the JPEG format.


Below are some tips and instructions to help with file naming and sizing using lightroom and photoshop. Note that the instructions for photoshop could be applied to other software packages so is worth reading if you are unsure of how to resize your images.

Lightroom tips for naming

If you are a Lightroom user, you can set up a Filename template which can then be used in the Hard Drive export settings:If you enter a title in the Title field for a photo in Lightroom, this will automatically be picked up in the Filename template, otherwise the filename has to be manually edited after export.

Note that our Competition Secretary loads all digital entries into Lightroom for presentation on the night, once loaded, each image is updated to include the name of the photographer. If you are a Lightroom user please consider typing your name into the “Creator” field as this will bring your name through automatically. If you use other post processing software and you have this option it would be a great help if you could add it in!
