Other Scanners
Other scanners may have different settings. The important settings are:
- Resolution: should be a minimum of 72 dpi for PCs, 96 for Macs for screen viewing, 300 dpi and above for printing purposes (check your printer's capabilities). Using lower resolution with make your files smaller and easier to load and store.
- Descreening filter: This will make your images look less fuzzy and avoid that scanned-from-a-book look.
- Target (output) size: 3,000 pixels on the longest side will produce a good-sized image from most books for presentation. If your image is tiny, you may need to reduce that size to 1500 or even 1000 pixels. If your image in enormous you may want to increase the size, especially if you want to zoom into the image. Images may need to be resized for printing.
- Jpeg vs. Tiff: If you do not need to change the look of your image besides cropping and rotating, you can start with making it a jpeg. If you will be changing the appearance of an image like changing coloration, sharpening, etc., you will want to start with a tiff. Make your changes on a tiff (to prevent archiving – jpegs that have distorted areas), then make a jpeg for your presentation. It will load faster than a tiff.
