Colour Mode
With colour mode you can change the images colour to 'sepia, black and white or even negative'.
For example: sepia
Negative:
When using any of these 3 different colour modes it makes the image much more interesting because you wouldnt be able to get that type of shade with the camera set to 'normal' mode.
l had a go and trying to use the colour mode 'sepia and black and white' and these are some of the images that I took of the outside.

AF Mode
AF Mode means Auto Focus. Basically whe taking a picture with using AF Mode the image would usually come out much more sharper than when taking a picture with normal mode.
These images are a extreme close up of a fire place. This first image is taken with the AF Mode on the highest number, you can tell that this image is much sharper than the other two images
This image is with the AF Mode turned down to the lowest number and you can see that the image is very blurry and quite un-recognisable.
ISO
ISO is how much light that your camera needs to take a good photo. I took a few pictures of outside when its light and the ISO is high and when its low, and also in the dark when its high and low.
This image is in the light with the ISO turned onThis image is when it was light outside and the ISO was on a low number. Because there was quite a lot of light outside there was no need to have the ISO on a high number.
The image is a picture in the light with the ISO turned up ton the highest so that more light will be in the picture
In this image it taken in the dark with the ISO on the lowest number
In this image it's taken in the dark but with the ISO on the highest number.
Photo Story
I have taken pictures of some of the daily after school routine. for example when I am on the bus on my way home.

In this image I am now back outside, but at the back of my house to put a bag in the bin.
