Tip: How to Address Curly Photos Using the Automatic Picture Feeder of the Kodak Picture Saver Scanner

Date: 2014-Nov-04

Reflective scanning of photos with the Kodak Picture Saver Scanner can provide high quality digitizing capabilities at a rapid speed. As a result, this system has revolutionized the photo scanning industry with its ability to scan hundreds of images an hour.

Dealing with heritage photographs originally printed onto paper can present certain technical challenges. Using the ADF (automated document feeder) offers the ability to stack multiple photos and scan without manually feeding each page into the scanner one-by-one. The input tray of an ADF holds the stack of photos and the internal rollers - designed especially for the characteristics of photographic emulsion - will grab each page one-by-one and feed them through the scanner.

However, many individuals store their photos in shoe boxes, bags or other containers that do not necessarily comply with even the basic of proper techniques for photo preservation. Storing photos in less than optimum conditions for long periods of time can cause them to develop a 'condition memory' of sorts. Condition memory can result in curling due to storage in improper humidity conditions. This phenomena can make image quality images when passing through the Picture Saver Scanner, depending if the curl is concave or convex in relationship to the emulsion.

Scanning Curled Photos - Convex 

The Kodak Picture Saver Scanner is designed to allow the safe transport of all photos with its special gentle emulsion handling straight transport path. Yet, those photos curled with an excessive convex configuration (middle of emulsion side bowed up with outer edges turned downwards) can create in a slight area of penumbra on the image as it passes through the scanning element. This is a result of those extreme edges of the photo with a large convex curvature causing a region where some, or all of the light source used to the scan the image to be obscured.  To accommodate for this effect, use the automated edge crop feature capabilities of the Kodak Picture Saver Scanner. This features allows for trimming this area out of the image.

Scanning Curled Photos - Concave

Photos with a prominent concave shape (middle of emulsion side surrounded by the outer edges turned upwards) also offers a unique challenge with regards to the Kodak Picture Saver Scanner. This is due to the configuration of its top scanning element. With no glass to interact with the curled up edge of the photo being fed through the scanner, it is possible for concave shaped photos with edges having a large degree of upward turn to become caught up into the aperture of the streak eliminating image guide. To manage these types of photos simply flip the photographs over and scan the emulsion side down, using the scanner's back-side scanning element in combination with its automated edge crop feature capabilities. Doing so permits safe passage of photos with a concave curl conditioned memory.
