Revised September 2024
Required specification

Competition image requirements

  • Fit the complete image within 1600 pixels wide × 1200 pixels high, including portrait images.
  • Save as a high-quality JPEG.
  • Use the sRGB colour space.

Before resizing

Finish the image and save or export it from Affinity as a JPEG. Convert RAW images to JPEG first. The steps differ for landscape and portrait orientations.

Landscape image

  1. Open the finished image with File → Open.
  2. Choose Document → Resize Document. Set Units to Pixels, DPI to 300 and Resample to Bilinear. Tick Resample and make sure the padlock is locked.
  3. Enter 1600 in the left-hand size field, then press Tab. The other dimension updates proportionally.
  4. If the resulting height is more than 1200 pixels, cancel, close without saving and follow the portrait method instead.
  5. Select Resize.
  6. Choose File → Export and select JPEG.
  7. Set Preset to JPEG (Best Quality), Resample to Linear, Quality to 100 and Area to Whole Document. Ensure “Don't export layers hidden by Export Persona” is unticked, then select Export.
  8. Choose or create a destination folder, give the file a meaningful name and select Save.
  9. Close the document without saving unless you intend to overwrite the original with the smaller image.
