[Radiance-general] Composing multiple radiance images

[Giovanni Betti]

Hi Jack, thanks for the quick reply, 

I am not performing any filtering but maybe there is something happening
behind the scenes...
I simply set up a job generating 9 images using rad and then a simple
pcompos line to tile them together

	pcompos -a 3 test00*.pic > composite.pic

is this offering more insights?

Thanks,

G

Hi Giovanni,

Are the images being filtered in any way before pcompos? If so this is 
where your variation is coming from....
