We scan at 3000 or 4000 dpi and burn the tiffs to DVD. NO need to ever rescan. Images are of publication quality with no to very little color correction. All color correction is also done within the scanning software NOT photoshop. Ideally scanning or photographing a RAW image is best save that as a TIFF convert or copy image to JPG and manipulate as needed.

Hi all: We're currently having a debate about the appropriate scanned image sizes for archival documents. Our scanner doesn't scan into RAW, so we're batting back and forth whether to save the master TIFFs as 600 or 300 dpi. On the 300 side: 1) many of our archival materials were already scanned at 300 dpi (that being the original size I designated, but we've a long way to go yet) 2) the majority of our reproduction requests are for 300 dpi JPG 3) storage space concerns 4) archive materials are mostly documents and don't necessarily need 600 dpi treatment 5) since the documents aren't "precious" like the 3D materials and photographs, we can go back and rescan if we really need a 600 dpi JPG (ie. handling concerns aren't as great) On the 600 side: 1) scan once and be done with it 2) we do sometimes receive 600 dpi JPG requests 3) storage is cheap 4) make sure the master TIFF is as high as quality as possible, since we don't have RAW to fall back upon We're also thinking about scanning the documents at 300 dpi, and photographs and 3D materials in 600. What do other institutions do? Any best practices we should fall back upon here? Thanks in advance! Perian Sully Collection Information and New Media Coordinator Judah L.
