holy smoke .. there goes my budget .. lightspeed

any other suggestions on shooting HDRI pictures.

I've tried with a regular digital camera but I'm not really happy
with the results.

Well the first question has to be, do you actually know how to take hdri images? ie. do you have a mirror ball, suitable cam and software?

ya3: thanks ..

imashination: Well the answer has to be .. maybe

I've tried two paths ..

Path one

1. Taking pictures of a mirrorball with a digitalcamera at diffrent exposures
2. Assemble them i HDRShop and make a HDRI image.
3. Assign the image to a sphere in MAYA using a lambert shader and the color and ambient slots.

Path two

1. Taking one picture of the mirrorball
2. Faking diffrent exposures by creating them in photoshop
3. Assemble them i HDRShop and make a HDRI image.
4. Assign the image to a sphere in MAYA using a lambert shader and the color and ambient slots.


This gives kind of descent results but it's alot of work to get it right. I was looking for
a cleaner solution and I've heard people talking about cameras that can do this.
But I havn't seen any besides the SpheroCam ..
Also the pricetag for that camera scares me off.
Any ideas or experience with alternative soultions? ..

You could also try doing it with panoramic lenses and stitching ;)

Also, some digital SLRs use the HDR format... not sure about what it does, though.

Well I own a nikon D70 and a fisheye 10.5mm lens and ive been experimenting using the techniques found on this page http://anti-matter.co.za/Freelance_HDRI_Services.html

While the D70 will set you back about 1000$ US and the Nikkor 10.5mm Fisheye about 600$ US, it is significantly cheaper and less hassle than more expensive setups or shooting film with a mirror ball and having to unwrap everything.

Hope this helps a bit or gives you some more options.

Btw, the Nikon D70 rocks

edit: just found another cgtalker using the exact same D70+ 10.5mm fisheye setup as myself.

The problem with the fisheye lens of course is that you only get half of the image, no?

[Apollux]

You already have the mirrow ball and the software... and most serious cams will take care of the braketing for you.. so.. your next move is quite obvious.

By the way, I'm already saving for the Nikon D70, i'm kind of in love with that camera. Zeio, is it's highlight-blow tendency as strong as some people suggest?
