Watch out for photo bombers
The standard culprits include younger siblings, crying children, and dogs taking a bathroom break on the lawn behind you. Before you snap your selfie, take a quick look around to make sure that no one and nothing is lurking in the shadows, waiting to ruin your moment.
Of course, if a photo bomber still manages to sneak into your selfie, you can always retake the photo after the intrusion leaves. Just make sure to check the background thoroughly before you upload your newest selfie.
Sometimes photo bombers actually add to the selfie! Dont discount a picture just because it has your little sister in it. Her goofy face juxtaposed with your serious one could make it that much more interesting a picture.
If you do not want to re take your selfie, you can always remove the photo bomber using an image manipulation program, or just crop your image using your smartphones built in image editing features.
