Clean the Plates before scanning There may be tiny specs of dust and dirt that have collected on the surface of the glass plates, which can adversely affect the quality and clarity of the images produced when digitising them. For example, I have just started the project and was scanning to a jpeg. This will probably work pretty well. Even then, it was touch-and-go on a few, requiring much burning and dodging. The gelatin dry plate glass negative was introduced commercially in the 1860s. Our images are exposed with either a laser beam or an electron beam rather than focused white light.
Printing pictures from glass negatives reveals a Victorian era world in sharp, fine detail. I've made prints from a 5x7 plate in my Besseler 45 enlarger, but I couldn't get a full image. Somewhere south of Amarillo My thanks to everyone who replied and for all the excellent info. I scanned about 80 of the quarter plate glass negs that my grandfather took on his Sanderson Hand Camera in the early 1900s. These are the folks that make this page possible, so please tell them that you saw their ad on Harry's Ad Pages! The experts, working together for almost one year, have emphatically determined that the negatives were in fact created by the iconic photographer Ansel Adams. Then you'd print from the chrome, or scan it and invert the chrome would be a positive of the negative, ie it'd look and work like a negative.
I do appreciate all the advise on this forum. What is your scanner make and Model. Or is this likely to damage either them or less impoartantly the scanner?

Provided the scanner glass is clean and you lower the neg gently into place there should be no problem with scratches. Many of the negatives were taken using the camera pictured below. The film holders rasie the film above the glass plate and that's where the focus is set.
I should receive the negs in about a month. We do not automatically renew subscriptions, however you will be contacted prior to the expiry date and you may choose to renew if you wish. I took out the negative carrier and put the plate in the same slot after covering the metal parts with paper tape to avoid scratching the plate. These two images are posted on this website to the right. So, right away I recognized it as Yosemite. It was standard studio procedure from 1900 on to cull negative files every five or so years, throwing out old negatives taken at least five or more years earlier… thus in say 1905 they would throw out the 1900 negatives — unless they were of prominent people or provided recurring sales views and scenes and newsworthy shots where the photographer would have the ability to make more money from them over time.
We were both shocked to find several tons of old glass negatives and, although the most were beyond salvaging, many thousands were saved. We find that, for the majority of the organisations we work with, 16-bit pixel depth is an ample amount for their glass plate digitisation projects. This process, including exposure and processing, had to happen immediately before the plate dried. That will hold a lot of images. About 200 at a guess.
We hired an eight ton truck and filled it three quarters full… and did it a few times while I worked there. It was used until the shop was closed in 2009. I'd like to digitise them for posterity as well as either make my own inkjet prints or take them to a pro shop for printing. If you're really concerned about damaging the negs, you might consider laying down a piece of transparent acetate or something similar on the scanner. Glass plate printing was an involved process that can be simplified by modern methods and materials. I will say that the scanner software I have used results in pretty soft images, I have had to sharpen my scans quite a bit to get them to make good images. But I handled them enough to gather how delicate they were.
Glass plate negatives are one of the most fragile mediums that archivists and holders of special collections work with, and requires a special level of care and attention. Would prefer to avoid the time required in Photoshop if possible How many do you have to scan? Before the film era and way before the digital era, photographic emulsions were made on glass supports, known as glass plate negatives. The loss in sharpness should be tiny, essentially zero in the final prints. You can clean the base glass side like any other piece of glass. Subscriptions will be charged to your credit card in Australian dollars. Ironically, his gamble at selling the photos to the federal government failed and he went bankrupt.
Adjust and tweak the images until they look just right. Blow them up to 20-by-24 inches as the emulsion has no grain. I am not in possession of these and am beginning the task of digitizing them. I have an Epson V700 which I bought for the task and so far have had good success. It is a pity that warnings are not given in time. Maddox, in use from the 1870s.
