Fig. 4From: A study of the relationship between the migration of image silver and perceived yellowing of silver gelatine photographsReflectance spectra for an un-aged, aged 50 °C and 70% RH and aged 50 °C and 90% RH well processed (WP) and insufficiently washed (IW) fibre based matt test photograph step 08. The insufficiently washed measurements from the photographs aged at 50 °C and 70% RH and 50 °C and 90% RH have more reflectance in the red end of the spectrumBack to article page
