This was my first attempt at turning a picture black and white. At first i
enhanced it by removing the colour.

I then decided to use a better picture as it would look more interesting.
For this picture i created another
layer and then
inverted the colour. I used the
colourize tool to then change the colour of the picture to a light blue.

The sun goes black because it has been
inverted from a light orange. It stands out in my picture because of the rest of the picture being a lighter
tone.
FiltersYou can use different filters to change a photo competely. For eaxample i have used the noise filter to change this photo. As you can see the picture has become noisy and is blurred. I also changed the colour of the picture for added effect.
In this picture i have added a granite effect which looks quite different to other effects. To do this, you go to filter at the top of the screen and then select which filter you would like.

In this photo, i have changed the photo filter. I made the warming colour grey which subtly added grey tones to the photo.
Overall, filters are extremely useful for making photos improved. In the photo above, i really like how the picture has a darker yet cool side to it.
