SELF IMAGES

As you prepare to go out, you check yourself in
the mirror. Everything looks good. The hair style is
right, your complexion is tanned and your smile
could make Liam Payne jealous. Later in the
evening, when friends take photos, you are happy
to pose for the camera. The next day, however,
when the photos are uploaded to the Internet,
you are shocked. You don't recognise that person.
It can't be you! The facial features are all wrong,
the skin too pale and the hair is horrific. 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 later on. You
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 chin 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, often 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, there is the comparison with the people
around you. Why do they all look so good in
photos compared to you? Even those who aren't
as attractive or slim as you? The reason is that
you know exactly how they looked all evening
because you could see them. There are no
surprises. However, you are comparing yourself
not to how you really looked but to an image of
yourself that was in your head. An image in which
your complexion is clearer, your eyes bigger and
even your clothes are more stylish.
So what can we do about it? On the one hand,
for all the reasons above, photos of ourselves will
rarely please us. There's a reason why many
celebrities do everything they can to not be
photographed in public. On the other hand, you
should remember that your friends feel exactly the
same. So, when they look at photos of you, they
will be as jealous of you as you are of them.
Take comfort from that but maybe avoid looking
at photos taken of you which appear on other
people's social networking pages.
