What's the best HDR resize tool?

I've noticed when resizing a 32bit image in CS2, it creates artifacts around highlighted edges/objects. Does anyone know of any good image resize tool that works well with very large hdri's?

Bubba,
Try the free HDR tool from Christen Blochi, Picturenaut.
http://www.hdrlabs.com/picturenaut/index.html
Or there is the commercial Artizen HDR. But I like Picturenaut, a very simple but power program, and it's free.
Cheers, Ron

Edit: Oops, Ron beat me to it
I didn't know maxwell could resize images.
Or do you mean setting up an orthogonal cam & plane and rendering it to the desired res?
Btw I'm liking these sIBL tools that were posted in the pfstools thread!
There are a lot of links to free and lowcost hdr viewing and editing applications on the hdrtools site.
You might find what you're looking for over there

JorisMX, get Christen's book...it's worth more than I can say.

Yeah I figured that out browsing his site last night.
I have the original german PDF printed out sitting inside my desk for a while now.
Looking at the new English version though makes me wanna press the money button hehe

Doesn't this take far too long considering maxwells rendertimes?
I mean its cool for interpolating up with high quality but I would guess a hdr editor would need less than 1 minute to scale a hdr depending on the machine.

Picturenaut will not handle the large hdri's I am trying. It must be a 32 bit app and only use 2 Gb max...

@jorisMx
sure! ..it is more the swiss knife solution..
@bubbaloo:
i was just thinking that.. your post just came in 2sec early
although when Bubbaloo speaks of
very large.. it has to be a solid piece of software to handle it

What size HDR's are you working with? I was just playing around with 500+ MB at 10K...and Picturenaut didn't even blink.
I don't know if it's 32 bit though....
Oh well...

The one I was testing it with was 10k and +/- 500 MB also. It opened it, but crashed when I tried to resize it. It wouldn't even open a 15k hdri.

Yeah, I agree, it is time for these programs to go 64 bits.

ps in cs4 is 64bit..
cs2 only had very basic hdr support, should be better by now.
