Basic HDRI questions - Format for HDRI

Hi i know there is loads of information about IBL and HDR - but ive done some searching and reading and still cant find any answers to a couple of simple questions, so was wondering if someone could answer these for me:
When shooting images for IBL what is the correct format to shoot in? I'm guessing jpgs and raw are no good?
Is it possible to use normal panoramas, shot with a wide angle lens, ie non-fish eye or chrome ball images to achieve acceptable IBL setups?
Thanks

Either will do. Raw generally gives better results but it's perfectly acceptable to use JPG files. If shooting JPG, you'll probably want to shoot a larger set of bracketed exposures.

You can create the panorama however you want. Fish-eye and chrome balls are typically used because it's quicker to get a full panorama - a fish-eye can get a full pano in 3-6 photos while a chrome ball gets close to a full (I forget the actual amount of degrees it can capture) pano in 1 photo.

Thanks for the rpely. Thats good to hear, so will it work with standard panorama with a normal lens? With a chrome ball or fish eye you get more information from above and below where with a normal panorama the image is obviously cropped above and below, making it not great for mapping on a sphere.
