Firstly scan your damaged photo at as high a resolution as possible (SHOULD BE AT LEAST 600dpi at same size). Scan all photographs in colour and include any background material you want to show. For example, a scan of an original at about A5 size, at 600dpi will create a TIFF file of 8mb.
When you upload your image(s) to us, we can advise you of what size you can use the restored image for print on paper.
Scanning in jpeg format should be avoided as it provides less quality.
WHAT DPI SIZES MEAN FOR YOU.
Scanning at 1200dpi (A5 original) may be slow, but allows you to provide a file that can be printed on paper at A3 size (420mmx297mm) or (16”x12”). These scans can be used at 6000x4000px size on screens. That will show beautiful images on huge TVs or 27” Apple iMac monitors.
600pdi allows us to provide you with a file that can be printed on paper at A4 size. These scans can be used at full size on computer screens.
Our information is general in nature and does not discuss scanner quality, dynamic range and other technical matters that provide the BEST scans. It is here for you to save money and get a reasonable result.
A typical home printer/scanner has the following:
600 x 1200 optical dpi
Scanning Bit Depth (Input/ Output)
Greyscale: 16bit/8bit, Colour: 48bit/24bit (RGB each 16bit/8bit)
