Apart from being a day of remembrance for Australians, April 25 is also Worldwide Pinhole Photography Day (WPPD).
On Sunday, photographers are encouraged to take time away from fancy cameras and engage in the simple, pleasurable act of making pinhole photographs. If you're unsure of what pinhole images look like, here's a gallery to get you inspired.
If you don't own a pinhole camera, the WPPD website has some advice. Alternatively, you might want to try some DIY camera hacks to make a pinhole lens cap for your digital camera. Once you've taken your images, submit them at the WPPD website.
