Hi everyone,

does anyone know of a tutorial on creating HDRI panoramas (like the ones from Hyperfocal Design), then to be used to illuminate scenes. I'm looking into creating my own, but i'm having a hard time finding a step by step tut.

Thx.

Alen, my apologies but I'm afraid i'm not getting what you're trying to explain.

I just realised my question wasn't precise enough. I'm actually looking for information on what type of photographic equipment is needed to create panoramic HDRI's and the process of creating them.

Many thanks.

Hi Nupsi, sorry for the VERY late reply, and many thanks for all the links. I have googled it and got more or less the same results, which isn't exactly what I'm looking for.
I'm looking into creating one of these type of HDRIs, used to illuminate CG scenes.

In a nutshell, you need any camera with which you can manually control the exposure levels. Obviously, some are much better than others, but that's a discussion in itself. Then you need a chrome ball. You can usually find these in the form of a 'bearing' from a machine supply shop, local availability will vary, the biggest I could find was 7/8" dia.

Basically, just take a range of different exposures of two views of your chrome ball @ 90 degrees to eachother. You can use the merge to hdr function of photoshop to compile the exposures into hdr images for your two views of your ball.

Beyond that, you can use hdrshop (free btw) to merge the images into a lat/lon environment map. Tutorials on how to do so are here...HDRShop (http://www.hdrshop.com/)
