Hi,

I've got a few latitude-longitude HDR textures I'd like to extract parts from to use as texture maps. But to be able to use them as texture maps I'll need to remove the spherical distortion from the images. Do you happen to know a (freeware) tool able to do this?

I've got Photoshop CS5, so once the distortion has been neutralized I can do the cropping with Photoshop. Or is it maybe even possible to remove the distortion using Photoshop CS5 as well?

Thanks in advance for your help.

Thanks Tom! I've worked with HDRshop a long time ago. I guess I should convert to the cross type of image to remove the distortion?

I think you only have a chance to change the type of distortion.

Thanks again, I'll check it out!

Ok, I downloaded HDR Shop and tried to achieve my goal using Panoramic Transformations, but even the cross type remains distorted.

Someone suggested me to check out PTGui, I'll try that next.

No luck with PTGui as well, maybe the Pro version, but that is not freeware.
