As I had done the layout for the title in greyscale I thought I should add some blue to the design. My first step was to paste the design into Photoshop as a Smart Object. I then rasterised the object so that I could use filters with it. It was rasterised at 5000 pixels wide at 300dpi to ensure total clarity once it was brought back into Illustrator.

I then applied a photo filter of the same base colour of my design (CMYK based), this was to make sure all colour corrections would fit visually when added to my design in Illustrator. After making the first change, I copied the title and used the 'Place' function in Illustrator to add it to my design. This meant that Illustrator would reference the image that was being changed in Photoshop after each save. This meant that I didn't have to insert and resize the design every time I changed it, making comparisons between much easier. Once I settled on a final version, I unlinked the image so I would be fully embedded in the document without any referencing, this means that it will display correctly even if the original image is moved/deleted/altered.
