When scanning for blogs and the web, it is best to select the dots per inch (dpi) of 70-80, however the higher the dpi, the greater the clarity of the picture. This image was scanned at 75, and again at 150, 300, and then 600 dpi. [pictured in this order, from left to right and top to bottom.] There is a subtle moire pattern on the images at the top, but as the dpi gets higher; the shadow on her face gets clearer, and colours slightly brighter. 







Interestingly, scanning has better results when the image is gloss not matt, according to the scanning tips from Digital Fashion Communication.
