[Digital BW] Re: QTR Linearization Question

2005-04-14 by Johnny Eades

Thanks to everyone for their input. I guess it's back to some more 
experimentation for a while until I can get a densitometer. On top of 
all this my Nikon D70 died on me after just 2 months. It's at the 
factory getting fixed. They say things happen in threes---what's next?

Your friend in Photography,

Johnny
