Re: Scanning Glass Negatives
I did not have much success with scanning glass negs, and not volume enough to warrant purchasing new scanner! I found that putting them on a lightbox and photographing them with ordinary digital camera on macro produced quite acceptable results.
not having a light box I improvised this by simply putting a sheet of white A4 onto an overhead projector screen, gave 80 watts of light via a fresnel lens. improvements would have been to mask around the glass negative, work in a dark room, and put black cloth over the rest of the ohp optics. a mounting for the camera would have been good too.
an example of the result is attached; this is one of the better results - enough detail to show the individual tiles on the roof, but crucially recognise the people in the image - my grandparents and uncles, the photo taken probably around 1918ish, and is off a glass neg.approx 100mm x 75mm I have used irfanview to crop it, convert to greyscale and from negative to positive, reduced in size, and saved at jpg compression of 49 to reduce the file size for the upload, so the original 1.49 MB was much better. I've made no adjustment of either contrast or brightness.
