When I saw how expensive it would have been to develop and print every single roll, but mostly when I realized that nobody could scan my Spinner negatives, I decided to buy a film scanner. And like every lomographer like me, I had to fight against our most terrible enemies: the Newton Rings. Read how to defeat them, after the jump.
I found a good definition of Newton Rings. ’Newton’s rings usually form due to interference created by reflection of light from a flat surface onto a spherical surface. In scanners moisture on either the negative or on the glass surface (the tiny spherical droplets of moisture are responsible for the concentric rings in the pattern) can result in this problem.’
Professional photographers suggest to buy an “anti-Newton glass” to avoid this problem; also the DigitaLiza mask should work fine, avoiding the contact between the negative and the scanner’s glass. I found another tip that works, that is putting the negative in the scanning mask back-to-front, with the natural “curve” of the negative (caused by the canisters) up, but I think that the images lose a lot of their definition. So I found an easier way to defeat this terrible enemy.
All you have to do is put something like a thin cloth between the upper and the lower part of the scanner, leaving a little space between the film and the glass. For better results in scanning, you should cut your negatives and leave them for some hours under something heavy, to make them as straight as possible… Et voilà! No more Newton Rings!
If you want to avoid the light to enter in the scanner because of the thickness you created, you can simply put a blanket (or a sweater, everything works good) over the scanner.
