In spite of the availability of high-quality colour processes, hand-coloured photographs (often combined with sepia toning) are still popular for aesthetic reasons and because the pigments used have great permanence. In many countries where colour film was rare or expensive, or where colour processing was unavailable, hand-colouring continued to be used and sometimes preferred into the 1980s. More recently, digital image processing has been used – particularly in advertising – to recreate the appearance and effects of hand-colouring. Colourisation is now available to the amateur photographer using image manipulation software such as Adobe Photoshop.
