Large images on backwall exhibits.
I have been asked by my employer to create a "look and feel" for an exhibit we will be having in June. The backwall is an 8ft display and would like to get some advise, suggestions on how to use an image to use on it without it looking stretched or pixelated if you will.
The backwall is similar to this one
Do I need to have a large scale image to use for this? I know an 800x600 would look horrible but I am wondering what size would be ideal for using.
Any suggestions comments are welcomed and much appreciated.
