I know that selfies are an "evil" of this generation, and you're never going to get a good picture when taking one of yourself, let alone when you are unable to compose it bc you can't see the viewfinder, but I have a technical question. My current camera is a canon s95 which is incredible. However my wife and I often find that if we try to take picture of ourselves with something in the background, eg. when we are traveling, we take up so much space in the picture and can't see anything else. Of course this is the nature of a selfie, to some extent, but is this also related to the zoom angle? The widest angle on the s95 is 28mm. If I were to use a camera or lens with a wider angle (eg. 24mm), would that make a significant difference? How much difference does 28mm vs. 24mm (wide angle) have on taking selfies?
Rather than considering a whole new camera, as the S95 is a rather nice little thing, you could chuck a small tripod in your backpack for these shots.
This would allow you to compose you shot with your wife and use the self timer for the photo.
Gorillapods are tiny enough to go in your pocket and can grip onto benches, railings, or branches or you could look into a light weight monopod to extend your reach if you don't want to let go of your camera.
This is easy math, fortunately. 28mm is 1/6th larger than 24mm, and correspondingly, your selfie taken from the same position will be 1/6th wider. If you stay in the center of the frame, you gain an additional 1/12th on each side, or, expressed another way, about 8% more on each side.
