My son placed the white knight in front of some pillows (forest) and I asked him to take a picture of: ‘the white knight in the forest’. We looked at the picture preview and talked a little about how it actually was a picture of a lounge with lots of toys in and that the knight was a bit hard to make out amongst all the other items in the image. We took a new picture this time only showing the knight and the forest.
If you want to know more about creating ‘coherent’ stories using images, look at children’s picture books or comics. You can also ask yourself which images you would need on a page to best remember the story (it can be difficult to remember which character is talking if the page only has a mouth on it). AND you will need to remember the story as when you book arrives you will have to ‘read’ it countless times!
