not-new
Chart zur Messung des Dynamic Range für Scanner nach ISO 21550
For scanners the only requirement for the arrangement of the patches in a dynamic range chart is to avoid flare as much as possible. This means the brightest patch should be far away from the darkest. ISO 21550 defines how to measure the dynamic range of scanners and recommends a chart which consists of 24 patches in a special arrangement used in our TE240. TE240 is a 35 mm slide used to measure the dynamic range of film scanners. It is available in to versions a 10,000:1 (4 densities) contrast and a 1,000,000:1 (6 densities) contrast. There is a free software to analyze the
scanner dynamic range available from the download section of www.i3a.org website representing ISO TC42 (the photography
standards committee).
