A collection of photographs composed to represent a Rainbow. I created this using photographic image manipulation software.

How did I create this picture?
I created this picture using Adobe CC 2015 Photoshop to make a single image from six individual photographs.
I looked at my collection of photographs for six images that had strong colours that when combined could describe the theme of “Rainbow” The main colours I wanted were in the pallet range of Red, Orange, Yellow, Green, Blue, Purple. Any photographs missing a suitable strong colour I went out and shot.
I composed the final by using Photoshop, this was so I could put all of the smaller pictures together to create one big collage picture.
I launched Adobe Photoshop 2015, opened in Photoshop the six images I wanted to use. Next I opened a new blank document (Ctrl+N). I split the new page up by applying a grid guide of 2 cells by 3 cells, View, Show, Guides. I then clicked on the tab of the first picture, select the image, copy then click on the tab of the new blank document and pasted the image as a new layer. I then clicked on Transform so that I could resize the image and move it into place using the guides to show how big the image had to be. I repeated this process for the remaining 5 images. For many of the images I cropped the layer so that a strong colour image was shown. The close up of the poppy flower head, the purple/violet coloured chive flower head, the orange stripes and the close up of the individual leaf.
What went well?
Photographic montage looks very effective. I have the main colours of the rainbow in each image, and there is also a common theme of nature, plants and flowers that also ties the rainbow theme together.
How could I improve this?
On close inspection I could have improved the lining up of the images, there is a slight gap between the bottom four pictures.
