Natural sequences
Two or more pictures can be used to illustrate the successive stages of a flower opening , a seedling or a toadstool growing , an insect walk ing or flying , or a sea anemone opening out its tentacles . You may come across some actions such as a predatory insect devouring its prey quite by chance , and there may be little time for you to set up the optimum lighting .
Many successful photo sequences will be achieved only by careful planning of the framing and the lighting of the subject . The bud of a flower is much smaller than a fully opened bloom , so if you want to take all the pictures in the sequence at the same magnifica tion , you must choose a magnification for the bud which allows plenty of space within the frame for the flower to expand into . The body of a burrowing animal , on the other hand , be comes obscured as it digs down into the sand . You should therefore aim to fill the first frame completely with its body .
Sequential pictures can be taken in the field . You may have problems though if they are taken over a period of several days or even weeks , when the weather and lighting can change dramatically . For close - ups , in parti cular , a studio set - up where the lighting can be controlled will often be preferable to working in the field . Flash will be essential for capturing fast movements - I prefer it to tungsten light for most sequences since it ensures crisp images with the maximum depth of field .
Recording a sequence which spans several days or weeks is known as time - lapse photo graphy . A subject such as a flower opening can be taken on a series of separate frames , or , if the camera has the facility for recocking the shutter without winding on the film , as multiple images on a single frame . The life history of a butterfly will take several weeks to record .
A predatory plant
The Venus fly trap has highly modified leaves which function as effective insect traps . The picture below graphically illustrates an open trap ready and waiting for an unsuspecting insect , in this instance an unlucky dragonfly . When an insect lands and touches more than one trigger hair inside the trap , the two lobes suddenly close tight on the victim . Dragonflies are normally fast fliers , but the one which has been caught by the trap in the bottom right picture had badly damaged wings which were unable to power it away from the predatory plant . Both pictures were taken by available light . Lens 105mm micro - Nikkor Mag . on film × 0.3 Mag . on page × 2
Burrowing down
To take this sequence of a plains . spadefoot toad burrowing into sand , I filled a baking pan with sand and placed it beneath an overhead copying stand . A pair of electronic flashes were set up on opposite sides of the tray . I prefocused the camera on a piece of wood the same thickness as the toad . As soon as the toad was placed on the tray it began to dig into the sand . I quickly checked the framing and focus before taking the first picture , and as the toad sank into the sand I had to adjust the focus .
