# [[Vuescan]] https://www.hamrick.com/ One of the best all-in-one scanning tool. I have had a license for a long time(one time purchase). I recently signed up for a completely optional yearly contribution to the team, because they are relentless in keeping the software updated with support for new scanners. a big benefit of using this software is that the developers have reverse engineered the protocol of most of these scanners. Many of them operate on the network as well as on USB and therefore while using this software there is no pre-requirements of installing the driver for the scanner software itself, making this software the only requirement for scanning from your hardware. ## Common tips ### Increasing contrast in the scans I have found that manipulating the black/white points is sufficient to quickly increase contrast in most cases. Even if Vuescan does give us access to a levels too. https://www.hamrick.com/vuescan/html/vuesc32.htm#colorwhitepoint #### Color | Black point > The default black point is 0. Setting a higher value will cause tones close to black to become pure black, which can improve contrast. However, setting the black point too high will cause shadow detail to be lost. #### Color | White point > The default white point is 1% (that is, the brightest 1% of pixels are all converted to pure white). Setting a higher value will cause tones close to white to become pure white. This can improve contrast and overall intensity of the image. Setting the white point too high will cause details in areas of highlights (e.g. the gray puffs of a cloud) to be lost, making the image look flat. ### Double sided scanning I use the automated doc feeder in my scanner(a Brother MFC) a lot for scanning a bunch of documents quickly. That works best when the documents are single sided. But for double sided documents, [Vuescan has given a pretty good guide for a workflow](https://www.hamrick.com/vuescan/html/vuesc4.htm) on how you can scan doublesided documents almost as easily as well. --- tags: #software/vuescan links: [[Tech MOC|Tech]]
