A Christmas Cookie from Santa

Bill;

You can surely order them. I got the blue dye to improve the sensitivity of the Azo emulsion in some experiments. Yes, you can increase blue sensitivity with dyes, just not a great deal.

You can come visit me for a while - it's been in the low 70s the last week, and today is about 68F and raining...
 
Kirk, it has been the driest summer in over 20 years here. Everything is suffering. The worst part is that the temp was in the high 60s to low 70s last week and now it is in the 90s. So..... We expect 96 by midweek.

Thankfully, the humidity is about 33% but is expected to rise a lot tomorrow.

And, come to GEH in Oct and be my assistant as you have so ably done in the past. You and I can work in my lab for a week after that. Oh, yeah, thats going to happen no matter what. But, you can see the spot of honor my wife gave to your print of the Grand Tetons.

Best wishes.

The DVDs are here. I am going to randomly check a few and also work on pricing and distribution.

I agree in a sense with Bill that the book and disks should go together, but then again, you don't have to buy the DVDs. So, they are here and I am working on getting them out the door.

PE,
Just your agreement with me from a philisophical view is enough!. I understand your desire to start recouping your investment as early as you can. I also understand those who want to get started ASAP. But I will hold off and get the DVD when the book is ready. Then I will read the book befor I watch the DVD. I need to exercize my aging brain. Trying to delay ( or should I say slow down) sinility.

Bill
 
BTW PE,
What if some of the DVDs that you randomly check have serious flaws, and some are good ? Will you have to check them all ? That could get tedious!
Bill
 
Bill;

They have a checksum and parity checking routing for the original and for the disks as they are made. So far, no problems. The company is very reliable.

Charley;

Tit for tat. I want several cases of your home brew!

Are the DVDs printed as an industrial CD, I mean with "embossed" bits, or are they like a CD-R?
In the second case waiting is not necessarily a good idea as the discs will fade over time. You know how these projects go. The book might be 18 months away. And by then, the DVDs will be 18 months older.
 
Just what happens when a CD-R "fades"? Dose the color fade ? The sound fade? The aroma or taste? I would hate for a salty-sweet DVD to become bitter. And I wouldn't like it if Ron's voice sounded like one of those old Italian Operas recorded in the 1930s.
Bill
 
I doubt anyone makes them (plain cyanine dye optical discs) anymore perhaps except for the super dirt cheap no-brand stuff CD-R's.

DVD-R's never used plain cyanine dyes as iirc they cannot be used for DVD's (I think.. maybe early cheap ones)

Many DVD-R's use Azo dyes (which make good CD-R's), the good DVD-R's dont use Azo, but cyanine derivatives (or modified) or pthalocyanine, like Taiyo Yuden discs and others.

The company that made these, claimed that conventional CD-Rs were inferior, and that they used a high quality disk and process. That is all I can tell you. They are also a big company and supply many other large companies with finished DVDs.

Ron, Should I give up

 
Bill;

The film will be slow. I'll work up from there.

You can do some pretty good R&D yourself. Why wait for me. I'm old and slow!

PE,
Thanks PE
Then I will not wait for you. I am very close. I just have to ballance the color sensitity. Then I have to look at some other factors, like accutance. But I don't know that I will need to. My goal is to make an emulsion suitable for in camera color separations. My speeds have surprized even me.
Bill
 
Here is the "cover" that I am working with for the DVD and the cover and first page of the book. It shows scenes from the DVD that illustrate each point. I am in the final stages of work on the DVD and the book is moving along as well.

Nice PE,
Are those your hands? Wouldn't KODAK have used slender female hands, with multi-colored nail polish?
Bill
 
I don't know... three color primaries, three color secondaries, neutral gray, white and black reference plus one left over for a resolution chart....
 
Ah come on Ron. You know that KODAK woulda played the non-subliminal,blatently sexual inticement forte`. That woman in the Color Chart-GHEEOW!!
