Many pictures.

We decided because of the millions of pictures me and tom had accumulated , to pick a few fish of certain types. we choose a couple that people love and a couple that weren't well known to mix things up a bit.
we also checked through each others pictures and deleted what we thought wasn't needed and kept useful ones or just ones we like in general.
we also saw the quality on the ones we checked to make sure it was possible the minipulate them in ways we wanted.
One thing we found was that  some fish where to Gray or blue or faint because of how the water distorted colours .

you can see this in the make up of the back ground.

you can see which bits are different pictures.
