fotoLibra's Quality Assessment Meter (QAM) – the grey line beneath each thumbnail – gives a quick indication of the filesize/resolution of each image.
The wider the line, the higher the quality and the larger it will print.
The QAM is based on the following factors:
• the size of the file in megabytes
• the file type
• the pixel dimensions
• the size at which the image will print @300dpi in both millimetres and inches.
