e alone will give you this, andeven the most expert photographer must count realsuccesses as things that do not often happen unless hehas complete control of the conditions under which his pictures are made, and of course, in working outof doors, with the ever-varying quality of light anddiversity of subject, the conditions are so changeablethat it requires great skill to produce much evennessin the quality of the photograph. In picturing flowers it is usually necessary to use afairly small diaphragm, as the camera is often quitenear the plant, and, with few exceptions, the leaveswill protrude toward the camera. Having to workwith so small an aperture, with an object as unsteadyas a flower, it is obvious that there is every advantageto be gained by employing a lens of great rapidity^though, of course, much good work is done withordinary lenses. Isochromatic plates are nearly always necessary,and at times a colour-screen may be used withadvantage. It is in the use of this colour-screen

In photographing a blueflower with even fairly dark leaves, the ordinary plate,being highlv sensitive to the blue and very slightlysensitive to the green, does not give the colour valuescorrectly: the blue is too light and the green too dark.The colour-screen or ray-filter will correct this.The common fault is in using the deep-coloured screenwhen photographing a red or orange flower. Theordinary plate, being only slightly sensitive to the red,orange, and green, requires a longer exposure thanwhen other colours predominate, but gives the valuesof these colours fairly accurately; the deep-colouredray-filter only tends to increase the exposure neces-sary. For most flower-work the medium isochro-matic plate is the most satisfactory. If the flower isvery shaky the quickest plates are best, and if whitefl
