First things first, you need to decide on what type of scanner it is that you want. Do you want a versatile all-round flatbed scanner which is able to scan all kinds of documents, or do you want a dedicated photo film scanner, designed specifically just for scanning photos? Or do you want a combination of the two, a photo film scanner that is also able to scan other documents.The advantages of owning a good all-round scanner is that you can use it not just for photos but for scanning anything. However, with a dedicated photo scanner, you will get a machine that is perfectly suited to getting the best out of your photographs, with excellent image resolution, highly sensitive color, slide and photo negative holders, as well as many other photography-specific features and functions.CanoScan 9000F offers a full 9600×9600 dpi optical scanning resolution, exceeding the fat burner 7200×7200 of the dedicated 35mm Plustek OpticFilm 7600i film scanner. If you crop 35mm film for enlargement beyond 8×10, this may matter to you, but for routine prints of 35mm frames, it doesn’t matter at allIt also includes seven EZ buttons on the lid dedicated to common tasks. The attraction of simply pressing a button is undeniable but it’s only really helpful when you really need a document feeder. When, that is, you have to repeatedly feed material to the scanner and run back and forth to the keyboard. For routine image scanning they really don’t come into play.More importantly, the CanoScan 9000F scans 48-bit color and 16-bit grayscale with an option to save those raw scans. Canon doesn’t divulge the density range of its scanners.CanoScan 9000F has evolved from the Canon CanoScan 8800F and boasts a number of new improved features to boost its productivity.
