Bob;
Solarization was orignally described as early as 1899, and the Sabattier effect was discovered way back when as well. They been "discovered" many many times by people who think it is something new. I don't have an original reference to Sabattier's work here.
I think that Mees, and Mees and James both debunk Jolly's nomenclature and have priority over Jolly as Mees was chief research scientist, VP and director of research at Kodak. In fact, he was the first, hired by Eastman. James is a name known world-wide in the science of photography. The first edition of this text was issued in the 40s, IIRC.
So, I have my source. I too wish Mr Jolly could be here to discuss it.
You see, someone often 'discovers' something that is well known in the photographic field, and they name it. "Gee, I have the 'Carnie' effect!" No disrespect intended, but we in the industry may have known of this for 50 years and may have patents and books on it.
So, there is no reason to dismiss Jolly's work, but 100 years in the future, I assure you that a diligent scientific reader may become confused over what people meant at this time period when they read of these different effects. They will be especially confused if these names are interchanged by us.
An inspection of comparable images, side-by-side, will reveal the differences in appearance of a solarized and a picture made by using the Sabattier effect. If the images are not readily comparable or are not viewed side-by-side, then this will become a difficult task.
If it works, use it. A rose by any other name would smell as sweet, but a chrysanthemum by any other name would be easier to spell!
All the best.
