I get my backgrounds from the excellent Airport Diorama Designs site. They can be printed using my work colour printer, however covering many pieces of paper there are two problems:
For my older smaller Dowse National diorama I had gotten the background professionally printed but even then it wasn't perfect. It turned out too dark once it had been finished. It was also expensive and now I needed a background twice as long. The answer was to make my own.
The next step was apply the middle distance and that is where the purchased background came in. It is easy to hide the paper join lines when there are buildings and foliage so instead of using the whole background I cut out the parts without sky on them. Even better where the outline was too complex to cut around I could use the different colour of the sky vs my new sky to create the appearance of hills in the distance.
Best of all the construction of this entire background took only an afternoon as the spray paint dries very quickly. Also I was able to reuse buildings to make the background as long as I needed.
These then slotted between the board and background for an instant treeline.
Add in the background and I think it looks great. It was so easy in the end I can't believe I hadn't tried this years ago. As you can see though I do need to extend one end a bit.
This has been one of the most successful parts of my work so far. No more mucking about with images after they're taken to get rid of paper join lines for me. Plus the whole diorama now joins together as one whole.
