It seems like to me, the center is bright and the periphery is darker. Learning curve or can you change the contrast like in photoshop, etc.?
Not sure if that's from the flattening or from the picture taking/lighting. Did I miss the price of that system?


Combination of both. The illuminating light brightness can be changed and it is a learning curve to get the brightness to match the gloss of the paper so as not to have too bright a spot in the middle of the page. One of the other brand scanners has some additional side lights to help with that situation but I chose not to go with it because it was the one with Mac software still in beta.

Software is also new to me so am feeling my way thru the options. I think the darker grayish edges may be due to the illumination light level and the fact you hold the pages flat with fingers on the page edge and the software removes your hand image in the final output. Not sure how that works so need more practice to see if it is persistent.

After scanning the carb pages above I was playing and discovered the icon to turn on additional laser lights to assist in positioning. That will probably make a big difference when the next project comes along.

As to price, it is fairly comparable to a flat bed scanner that can do the same page sizes. This one can do up to A3 which is about 11 3/4 x 16 1/2. With taxes it was about $360 at Amazon. There are less expensive units which will only do up to the standard 8 1/2 x 11 or maybe legal size 8 1/2 x 14 which was my old flatbed limits. A couple of others can cover up to a newspaper page size but those are over 1k.https://www.viisan.com/en/product/K21.html
