Ray;
Your post #52 was totally off the mark. Most of the others hit it right on.
This book was done as a labor of love. I have tried, but failed to duplicate modern emulsions at home, so what I did was to take my 15 years as a comparative emulsion scientist involved in emulsion modeling and scaling and use it to engineer several useful types of emulsion that can be done at home with less than about $5000 investment in equipment and chemicals. Options are shown for costs far less than this, probably in the $1000 level. I list the equipment for all options in the book and show (color) photos of all of it in use! The DVD goes into detail.
So, these emulsions, to the average APUG reader would be "cutting edge" as said above. The reasons being 1. Every emulsion has been made and tested more than once except for the warm tone Azo type emulsion; 2, All emulsions have been scaled from 100 ml up to as much as 5L, and also blended to prove repeatability; 3. All emulsions show variants that allow contrast control, speed control, spectral sensitivity control or combinations of the these (this feature alone making it totally unique among all emulsion making texts ever published AFAIK); 4. All of my emulsions given in the book are originals for one reason or another, and have not been published in this form elsewhere; and finally; All emulsions in the book are doable in the home lab with no special equipment except a hotplate-stirrer.
Last, but not least, I give reasoning behind everything done, and jumping off points for the brave, leaving a "cliff hanger" for myself as well in case sales go well. In doing so, I describe some of the Kodak technology that makes some of this doable and some that makes it very very difficult to do at home. That said, I can then move on from there and show either more advanced making or other techniques if there is a sequel or if I add to this book in the next few months before publication.
Now, to jump back a bit here. My efforts to make modern emulsions in my lab relate to the need for better high speed mixing (see my thread on stirring, mixing and homogenizing here on APUG). The need for precise delivery points in the kettle, and the need for precise baffles in the kettle to control eddies and other mixing problems are also involved. So, thus far, T-grains and cubes are within reach but need more advanced equipment and I am working on that.
At the present time, I am working on better mixing, but this ups the ante by as much as $2000. Who wants to spring for that?
And, there is the question of whether I should hold the book to include any success story or wait for a possible sequel. < Anyone listening to this particular question?? You see, this can be open ended. I can keep going for another year and completely cover the range of emulsions (If I succeed in making a modern emulsion), I can write a sequel, or I can offer updated appendices to prior purchasers.
Well, you get the picture. I am applying 15 years of emulsion experience and 32 years of overall product development work to this task. The emulsions are not just OTOMH. They are based on sound scientific methods of emulsion making!
