Sometimes you just can't fit everything into a standard aspect ratio. Then it's time to go wide!
I regularly produce bold panoramic images by taking several panning images consecutively and then using Photoshops automated panoramic stitch tool to assemble them. I think the results are great and can be applied to a number of different uses. The final images look great as banners on websites or splitting up large bodies of text on a webpage. They look even better printed out, nicely framed and displayed.
Here are some examples of how I use the panoramic in my commercial photography practice:
The construction site/exterior of a building
The office environment and lifestyle
