[Digital BW] Re: 100 Hour Direct Sun Torture Test

2008-11-11 by Clayton Jones

Hello Richard,

>I have your Condor paper here for the window test and now that 
>it's spring in NZ, plan to start that test with a few other 
>papers as well, asap.

Condor was one of my top favorites for Eboni BO, really beautiful
paper.  I noticed that Condor prints hanging here in my workroom for
several months would loose some brightness compared to a fresh sheet
(not whiteness, just brightness).  I figured it was rapid OBA
exhaustion, but since there was no loss of whiteness and it didn't
affect the print appearance I never gave much thought to it.  Hawk Mtn
has stated that they use naturally white fibers to begin with, so
there shouldn't be much, if any, color change due to OBA death.  I'll
be interested to learn what results you find from direct sunlight.

 
>I'm thinking that perhaps just printing a 21-step test strip would be
a good way to do it...

Definitely.  My landscape doesn't provide for spectro readings
anywhere in the image.  Next time I do something like this I'll do the
same.  This was such a casual thing when I began it, just a curious
thought.


>NZ is supposed to have more UV than many other countries so it's
probably a good place to do such tests.

Why is that do you suppose?  I don't know how S. Fla rates, but I know
it's real easy to get a bad sunburn here.  I grew up here fishing,
sailing, snorkeling, etc, and had my share of them.  We see lots of
bright pink tourists here in the winter <g>.


>Probably I'll do ... Moab Entrada (natural and bright), Colorado
>Satine, PremierArt Matt BW (Maybe some other PremierArt - like
>Platinum Rag), HM Sparrowhawk, Condor ...

That's a big lineup.  What inks?


>Oh ... another thing about the Wilhelm interview - he pointed out
that many of the great photographers in the past were even using
acidic papers and even those prints have stood up well.

There were lots of interesting tidbits in there.  I may watch it again.


Regards,
Clayton
