But with some scanners offering as much as 7200 dpi, you may quickly wonder if you aren't overdoing it.įile Processing. The guilt-free way to calculate this is simply to set resolution to the physical limit of your scanner. You can down-sample but you can't up-sample. So you have to scan to Raw format with sufficient resolution that any particular subsequent file conversion will have enough data. Though that high a resolution isn't strictly necessary, it can still be the entry bar for your image.
Worst case is running your 25mm image across two pages as a double-truck bleed while requiring 300 dpi from your image. How many dpi does the device require to print at the largest size you want? In some cases, the "device" may be a commercial printer or a publication. The key to this calculation is knowing what your most demanding output device requires. You can go as high as 7200 dpi on your desktop today but you quickly run into constraints dealing with the large files higher resolutions create. Some practitioners insists 2700 dpi is sufficient. The first is that you have to have scanned your originals at high resolution. To make this approach feasible, you have to have observe a few caveats. You don't have to access the film, clean it and rescan just to process it a bit differently. You can also batch process the Raw files into whatever file format you need with whatever settings you need.Īnd finally, scanning to Raw files minimizes film handling. The scanning operation itself is a bit faster, too, in that you don't have to wait for the application to process the infrared data before continuing with the next image. So even if, in the intervening years, your film has deteriorated, you've got the scan data from better days.

The main advantage of that is simply that you can return to the Raw scan data stored in the archival file (instead of rescanning) years after the scan when smarter defect removal software can do a better job on your original data. By separating the defect information from the color data (which, it must be noted, is not itself pristine), HDRi and RGBI allow you to postpone the defect removal and other image processing operations just as your camera's Raw format allows you to postpone all the post-processing that creates a JPEG. HDRi files also record a gamma value to help image processing programs render the expected contrast and files larger than 30 megabytes include an embedded preview.Īdvantages.

If you're scanning in black and white, that's a 32-bit HDR file (a 16-bit channel for grayscale tone information plus the 16-bit channel for infrared defect data). For a color scan, the usual red, green and blue data are available as 16-bit channels (for a subtotal of 48 bits) but LaserSoft has added an additional 16-bit grayscale channel to file (64 bits total). Under the hood, HDRi is also a four-channel image format conforming to the TIFF specification. It's available in SilverFast v6.6.1 and later. LaserSoft Imaging President and CEO Karl-Heinz Zahorsky recently wrote to us describing his company's nearly identical concept called HDRi (High Density Range infrared). VueScan can save the RGBI format as a TIFF but without a preview.
Color data is scanned in 16-bit channels for red, green and blue data (48 bits) plus a 16-bit channel for the infrared scan that documents the dust and scratches on the film.

Since version 7, the Professional edition of Ed Hamrick's VueScan has offered what it refers to as a 64-bit RGBI image format in 64 bits.
The formats are conceptually similar but not interchangeable. It can give you a worse headache than the whole bottle of wine.īoth VueScan and SilverFast can save a scan in a format that postpones processing - and all those decisions except which resolution to scan. What resolution? Which scanner? What software? Should you use defect removal to clean up the scratches? The trouble is that there are so many decisions to make. There's no time like the present to preserve your memories by scanning your old negatives and slides.

So leave the bottle corked and crack open the scanner.
