SELF IMAGES
As you get ready to go out, you glance in the mirror for a final check of your look. You're happy with what you
see. The hair is neat and nicely styled, your complexion is tanned and your smile could make any Hollywood
actor jealous. Later in the evening, you are more than happy to pose when friends get their phones out to take
photos. The next day, however, when the photos appear on social networking sites, you are horrified. You don't
recognise the person you are looking at. How can that be you? The noste looks far too big, the skin too white and
the hair is all over the place! So just why do we look different in photos to how we imagine ourselves to be?
There isn't just one reason. Firstly, people often look better early in the evening than lateran. Wuu have
probably just come out of the shower, brushed your hair and put on your elegant clothes. If there was something
wrong, you would do something about it and then admire yourself again. When the photos are taken, you may be
tired or perhaps full after a good meal. Your hair may not look quite so good as it did. Often, when people get
home and look in the mirror, they think: "I look terrible". It's just that, being home and alone, it doesn't matter.
Another reason is to do with angles. In the mirror, we see our nose, mouth and hin from above. This is
more flattering than looking up from below. We also turn slightly and smile trying to get the best look possible.
Unfortunately, our friends probably aren't as careful. Photos are taken when we aren't ready, osten from the
wrong position. You could watch carefully to see when someone is going to take a photo and pose for it but.
although the photos might look better, your evening won't be very relaxing
Finally, we all have a tendency to measure and compare ourselves against others. W. is it that other
people always look better in photos than we do? Even people who aren't as good-looking or dy't wear such
stylish clothes as you? The reason for this is that you could see them all evening, so you know eactly what they
looked like. The photos of them are not unexpected in any way. However, when you look at a photo of yourself
