The camera and material have been described under outfit.
Lighting and preparation of objects is a main element of success. When first looking over any ruins, make a list of every view wanted, with the time of day when the sun will be right for it. Then follow the time-table, and so get the best lighting all in one day. For movable stones or figures place them in half-shade, as a doorway, and then tilt every way until the best lighting is found, fix them in that position, and then set up the camera square with them. The camera should usually be fixed to look downward vertically, and then variation up to 40 degrees can be got by the legs. Hold the camera in the right position, keeping the legs off the ground, and then drop the legs to find their own place; thus very skew positions can be fixed quickly. Small objects are best laid on black velvet, and taken vertically. Scraps of charcoal are useful to prop them in exact positions. A sheet of white paper stuck on a leg of the stand may be useful to prevent shadows being too heavy. Where outline, and not flat detail, is wanted, then a light ground is best; the most perfect is a sheet of ground glass with white paper a foot or two below it. If the ground glass cannot be had, a good substitute-also useful for a camera glass-is plain glass with a sheet of tissue paper (or the packing paper of films) stuck on with paraffin wax. The dressing of objects to show up clearly is often needful. Incised objects can be filled in with charcoal powder if light, or chalk if dark; in any case a coarse powder, so as not to stain the object. For |
