Re: Pi-Scan and Canon a2500 - trouble connecting

This is called "white balance" and most cameras have a setting for it. Since incandescent lamps have a rather "warm" (yellow/red) light, the white balance setting to compensate for it reduces the red and increases the blue in the image. If you use this setting with true white light (daylight, LED la...

Re: A2-A1 scanner

Hello, gus, two years later. The Nikon D3500 you mention has 24 megapixels or 4000 x 6000 pixels.

Re: HoverCam ImPress Book Scanner

Can 5 megapixels really give good pictures of a printed legal-size magazine page? Their current products all seem to be 3 (T3) or 5 (T5) megapixel cameras.

Re: Ionaudio Booksaver?
