[Radiance-general] rtcontrib output crashes preview, finder

[John Ford]

Thomas, 

Got it working. 

In the meantime discovered that date in OSX doesn't return nanoseconds, despite Unix date returning nanoseconds. Also, I don't think 'recno' works on OSX. 

John.

In my own tests I also found other bins to be completely black but I was told that was because of my primitive test geometry. Doing Axel's tutorial test room seemed to work for me at the time. I could reproduce the results he got with similar accuracy.

If you suspect a single image to be corrupt just exclude that from the process and see if the pcomb command finishes.

I'm up to the first use of tregenza.cal to generate sky patches (command below) and finding that the first image, p000.hdr, is corrupted somehow. Preview crashes when I try to open the image and when I even select it in the Finder, the Finder behaves very strangely (I think it's crashing and restarting all in the space of about two seconds). Getinfo reports what looks like a correct header, comparing the headers of p000.hdr and p001.hdr. The files are all the same size. The other images, p001.hdr to p145.hdr all open fine.
