Set up a corner of a room as a small photo studio. All you need is a plain background (such as curtains or a painted wall) and a camera on a tripod. With an ISO setting of 800 or 1600 you may well not need to use flash, but this is an option. Then ask your guests to take a photo of themselves at some point in the evening.
You can use the Self-Timer but many PowerShot and IXUS cameras feature Smile or Wink Detection which make taking self-portraits much easier but also add to the fun of the occasion.
If you have a SELPHY you can print the photos off there and then; alternatively upload the images to your CANON iMAGE GATEWAY then let all your guests have access to the gallery.
With some time off, the festive period is the perfect time to learn a little more about your camera and try out some new ideas. So charge the battery, make sure there’s plenty of capacity on your memory card and then go out and create a memorable and alternative photo.
