Anti Newton Glass Scanning. For 120 and 4x5 negatives the 4990s film holders can be used with no Anti-Newton glass. More specifically a V600.
Professional photographers suggest to buy an anti-Newton glass to avoid this problem. When two flat optical surfaces are in close proximity interference effects associated with residual Fresnel reflection can be seen these are a special case of Newtons Rings. By chance with a very thin negative I accidentally placed the emulsion side matte side directly on the scanning surface with the glass on top.
During my years at London College of Fashion I had access to many great tools for photography including 4x5 large format cameras Tetenal C-41 dip and dunk tanks processing room and many more.
If you can find a high quality product like this for a lower price we will match or beat it. This includes V550 V650 4495 and related models HEALTH NOTE. Use a negative holder appropriate to the negative size. Anti-reflection properties is very good for wide range of angles.
