When one of you is not enough, you immediately make it two. The double selfie is the ultimate narcissistic selfie, acknowledging that you need to show your face twice, because, isn't everything better with just that?

In times like this, you'll want to have a front facing camera that's got some pretty high specs. 

1. Unless you're Kim, and you get someone else to take them for you.

2. But in any case, with a good front facing camera, you'll be able to perform the mirror selfie, with good results.

3. Some prefer to rely on an actual mirror. In any case, this might not play out as good for you as you think since additional lighting might cast too much shadow or over expose the picture.

4. Double selfies don't have to look the same in each. There are tons of editing apps that help you put two different poses into one. 

5. Always play with filters.

6. Contrast is important too as you don't actually want to blend into the photo.

7. Use a soft LED flash to create the perfect shots in any light.

8. Accessorize with a mirror.

9. Posture and pose make a ton of difference.

10. Make sure you've got the perfect lighting, always.

11. Use landscape mode to capture more in the background.

12. If your focus is just you, then make sure you don't take too much of the background. Cropping is good in this instance.

13. Use camera apps that automatically enhances your natural look.

The Xperia C5 Ultra Dual features Superior Auto for the back camera and front selfie camera. It senses the scene and adjusts the camera settings to match so there's not much effort to put in, except for your pose. Check it out here.
