Step 3 - Take a photo

Make sure the time and date are set correctly on your digital camera or camera phone. Then get someone to take a photo of you planting your tree or take a before and after shot if you are on your own. Remember; if you are planting more than one tree make sure you get photos of you planting them all.

Step 4 - Email us your photo

We need evidence to prove you have planted the tree so we can verify the record with Guinness.

Set the correct time and date on your camera.
The photo must be taken between 11am and 12 noon GMT - we will be checking this information from the photo.
Email us the photo - do not crop or change the photo, because this will change the date and time on the photo.
Email your photo to us at breathingplacestrees@bbc.co.uk, by 12 noon on Friday 11th December 2009.
Tell us what type of tree you have planted and the full postal address of your site, including postcode, so make sure you include this in your email.
