Maxwell do support only 8 bit per color at the moment. An other problem is the vignetting of the camera.

... and you know why there are just very few High Quality HDR panoramas.. because people that need these kind of High quality HDR environments usually rent a Spheron Cam and doit themselves... besides that... HDRI lighting is here to match real environment to match precisely as possible the real shoot... and photocomp on top of it...

I remember an adidas commercial on TV with a robot dancing... the HDRI was done ON location ... they could not have used any other.....

my 0.2 cents..

funny you mentionned Vignetting Micha... HDRSHop has a special add vignette thingy... and you need to remove it...

Look at Paul Debevec's web site there are links to many free HDR images. Plus, why not make your own, I have a 3 inch chrome-steel ball (glass gazing balls are also good, plus much cheaper) and coupled with a cheap digital camera and HDR shop (free) you can make v.good HDRs.

... and with AHDRIA is it a little bit simplier to make the image series with a small digital camera.

I use a chrom soap trowel with approx. 12 cm diameter and a Canon IXUS v².
Here a LDR example image ready to use as MXI.

Can Maxwell render HDRI panoramas?

I have a problem. I need good HDRIs for a graphics software project. Unfortunately, there are very few suppliers of high-quality HDRI panoramas, and not very much images to choose from. For example, Sachform offers superb outdoor images, but very few indoors/interiors.

I have an idea to try Maxwell to make some indoor HDRI panoramas. Maxwell is photometric, and I guess that outputting real-world light values to a floating-point file like EXR shouldn't be a big problem for a renderer of such a caliber.

Has anyone tried using Maxwell to do this?

Thank you,
Vladimir.

To get HDR, you need to get MXI output first. Yes, you could create an HDR out of several Maxwell shots with different ISOs as well. However, not only does that cost an awful lot of time, but you still need to compensate vignetting, which can only be done perfectly on the energy level, not on the image level.

P.S.: I also work for steinzeit-mediendesign.de in Düsseldorf, and as they have a SpheroCam HDRs, they have quite a couple of HDRs - indoors as well. So if it is a paid job, it doesn't hurt to ask them for pricing.
