I love digitalizing books and I always wanted the best scanning results for my big textbook. A good scanning has many features, including anti-shaking, brightness, contrast, cropping, straightening, etc. I tried a professional KIC book scanner at my university which turned out to be super slow and there was a lot of glaring. Tried Adobe Scan (claimed to be the best), but the resolution was terrible. Tried Scanner Pro, and its brightness$contrast was just disaster; its cropping is also another level of catastrophe. Microsoft Lens is also useless for scanning. However, vFlatScan gets everything. Simply the best.
