Context and Anchorage with evidence.

The correct way to interpret a colour, for example red, is often based in the context it is shown in. Red's connotation of danger is used in many different warning signs and so the circle with the diagonal bar is the context of our interpretation. Anchorage would be the way all the elements are put together in a sign to show meaning and interpretation. For example, where red is shown as danger, if it is used in a heart shape we immediately interpret this as a sign of romance and love rather than a warning. Often, we may realise that the photographs have captions or appear close to headings and headlines, this is because it is used to attempt to ensure that the audience interpret the picture like the newspaper or magazine intended the image to be interpreted.

Below is some evidence I have found that I can use to help back up the points of context and anchorage. The pieces of evidence I have used are from different newspaper articles with their proper headline and one that I have made up that show different meanings.

The headline for this story reads:
'Dozens of protesters arrested just yards from Downing Street after violence breaks out on strike march'
This headline makes us think of the mayhem of what is really going on at Downing Street and the seriousness of what has actually happened. For example, if it was a comedic headline the story would be shown in a different context and therefore not very many people would take the storyline seriously.
If the headline of the story read this:
'Daylight vampire protests ill thought out'
This headline would be seen as comedy rather than being serious because we know that vampires don't exist and the headline would be taking the mick out of the person who is dressed up as what seems to be as a vampire. Instead of taking the storyline seriously, we would take it as a joke because the headline is put out of context. Therefore, the way that the anchor has been used to portray a different meaning can lead us into interpreting the image differently.

The headline for this story reads:
'Sweets are 'good for children and may stop them from getting fat in later life'
This headline makes us think that it could be good to eat sugar and sweets and therefore it makes children happy because the headline is saying that sweets may stop children from getting fat in later life. Therefore, the image is portraying something happy and the context in which it's written in is positive and doesn't include chaos and mayhem like the previous example I have put on here.
If the headline of this story read this:
'Youngest pill popper ever takes bet'
This headline makes us think that is could be dangerous because of the way they have anchored this headline to the image shown above. It makes the reader think that having sweets at a young age is bad for you because  of the consequences that could happen. 'Pill popper' makes us think that they could possibly be addictive and therefore bad for childrens' health.
