Frequently Asked Questions

How big are the digitized images ("digital slides")?

Aperio Technologies FAQs
When scanned at 54,000 pixels per inch, a 15 mm x 15 mm area of a slide corresponds to a 2.8 GB file. A 20:1 JPEG2000 compression of this file results in a more manageable 140 MB file. Using a 40x objective lens (108,000 pixels per inch) the file size for the same area quadruples to 11.4 GB uncompressed, and 560 MB compressed. Smaller file sizes can be realized at higher compression ratios.

Are my slides and/or pictures returned to me after they are digitized?

mm Slide Scanning FAQ Digital Imaging
We have had a number of people that have sent many 35mm slide carousels filled with slides and told us to dispose of them when we are done. They have what they wanted: digitized images. They no longer have a need for the slides and don't want to pay to have them shipped back and they don't want to have to store them any longer.

Have the digitized images of the sources been changed at all?

Minnesota Historical Society | Minnesota Communities | FAQs
Yes they have. In order to make text-oriented sources more legible, they have commonly been enlarged. Conversely, very large charts or photographs have been reduced to keep download times to a minimum. Large sources may also have been cropped to feature only the section which is relevant to the unit; putting up an entire newspaper page for example seemed unnecessary.

How big can the images be?

IDELIX Software Inc.
PDT is not the limiting factor on image size. Image size is usually constrained by available memory and the specific application's use of that memory. PDT has been shown to work with images in excess of 100MB. Consultation with customers and partners is required to optimize the use of PDT within any image or display pipeline, whether the application is running on the desktop, over the Internet or on a handheld PDA. The coordinate system of the base image is completely maintained within the lens.

FAQ
Our images start as high resolution film or digital files. We find that by starting with large digital files, the non-object areas can be precisely removed leaving no stray pixels. Instead of decreasing the image size, we chose to maintain the original image data. This allows you to use the objects in close-up 3D work or printed documents.
