Saving Large PowerPoint slide as a tiff

[taraj06]

How do I save a large PowerPoint slide as a tiff without cropping or losing resolution?

I am not very familiar with PowerPoint, but I am very savvy in the Adobe software. A friend of mine has designed a very large (54"W X 36"H) and needs it to be saved as an image file (tiff, jpeg). Whenever we try to convert the file in ppt it crops the image - whenever we try to save as a pdf the resolution is lowered and the image becomes of very low quality.

Any advice?
