| Scanning 35mm Negatives : | |
 To give you some idea what the scanning quality can be from 35mm negative strips, look at the image above. It is the full-frame view of the "Olde City" of Quebec, in Canada, taken after sunset on a cloudy day. The full frame scan is 2400x3600 pixels, done from a 4-negative strip, just as comes from the photo processor. The film is Kodak CB-200, off-the-shelf ASA-200 consumer-film, shot and commercially developed in August 1988, and the negative scanned in January 1998. The image displayed here is 514x343, or about one-seventh actual size. Notice a brightly-lit building, vertically-centered, about 1/3 of the image-width from the right-hand edge of the picture. There appears to be a church spire slightly to the left of the bright building. That small section is shown full-size, below. For the sake of web-bandwidth, all images are 50:1 JPEG compressions of the originals.
 Now, not all images have detail that can benefit from such high resolution, and the scanning software can analyze an image and suggest lower resolutions than the maximum, but its nice to know that if needed, your images can be THIS sharp. Another consideration in hi-res scanning is storage. This full-frame image, in uncompressed .TIF format is a whopping 26 megabytes, so it is only practical to do these images if you are also going to pay to have them put on a CD for return to you. |
