http://i.huffpost.com/gen/1498740/thumbs/o-HIDDEN-MOTHER-4-570.jpg?6 The main problem was the length of the exposure. However bright the photographer’s studio, it took up to half a minute for an image to register on wet collodion. Getting an adult to sit completely still for half a minute is a challenge, but getting a wakeful baby to do so is near-impossible. The photographer could position anyone old enough to sit on a chair by placing an electric chair-style head clamp behind them, but the only way of photographing a baby was for the mother to hold it (or dope it with enough laudanum to keep a grown man rigid for a week).
The results were often extraordinary – as a new collection of these photographs, called The Hidden Mother, shows. Though there are plenty of Victorian studio portraits of family groups, there are also many in which the mothers are concealed: they’re holding babies in place while impersonating chairs, couches or studio backdrops. They wanted a picture of just the baby, and this was the best way to achieve it. Sometimes, the figures are obvious, standing by the side of a chair and waiting to be cropped out later; sometimes, they really do appear as a pair of curtains or as disembodied hands. To a 21st-century viewer, the images look bizarre – all these unsmiling children strangled by smocking and framed by what appears to be a black-draped Grim Reaper, or by an endless succession of figures in carpets and chintz burqas.
