The fact you’re reading this page means you are probably thinking about getting your photos scanned?
Well you’ve come to the right place. Read on for all you need to know about resolution and DPI.
Zoom in on both photos and compare a part of the photo that interests you. You’ll notice you can zoom further into the 600 dpi one, before losing quality.
For most purposes, 300 dpi is fine.
Certainly all digital purposes. It’s also fine for printing photo books.
IF…you are printing anything large format, you might want to consider 600 dpi.
Whenever you take anything beyond its original scale, you will get image degradation. 600 dpi means you can enlarge things a little more before you hit that degradation.
Most ‘holiday snaps’ most families have, were printed at 300 dpi. Therefore you can even reprint a whole set of your scanned photos.
The biggest factor of how well a photo scans and the quality we can achieve, is the quality of the original. Typically, photos from the early 20th or late 19th century will scan very well as the camera lenses were very good and the printing very professional.
Some very rough thoughts:
Most photo books
Reprinting standard quality photos
Larger format printing e.g. A3 book with full bleed (cover to cover) images
You notice micro details and are a photography enthusiast
You simply want the best
Budget is not a problem (600 dpi costs more simply because it takes 9X longer to process a scan)
