Working with aquaria
Aquarium fish , as well as small invertebrate life , can be photographed in aquaria very successfully . Glass tanks are better than plexi glass ones for photography because they do not scratch so easily . Make sure there are no blemishes scratches or air bubbles - in the pane through which the photograph is to be taken . As well as using ready - made aquaria , I make tanks by getting glass cut to order and bonding the edges with a special adhesive .
Photofloods quickly warm up water in a small aquarium , so I always use electronic flash , which also freezes the movement of active animals . Depending on the subject , I may use one , two or three flashes to light it . The color of the background and the position of the lights are selected after I have observed the subject for some time . A major problem with tank photography particularly when using a black background - is the reflection of the camera and hands in the front glass . This can be eliminated by attaching a matte black mask to the front of the camera lens . Small active subjects can be confined to part of the tank by inserting a vertical glass partition .
Portraying a moving fish ▷ I watched the behavior of this red liontail goldfish observing that it swam round in circles near the top of the aquarium . I then set up an electronic flash on a stand ( see above ) so that it shone down from the top of the tank and I pre - focused the tripod - mounted camera a few inches inside the front glass wall . I attached a matte black mask to the front of the lens to eliminate all reflections in the front glass . As the fish swam into the field of view I quickly checked the focus , before releasing the shutter . Fortunately , the flash recharged before the fish completed its next circuit . Lens Hasselblad 150mm + 42mm ( 21 + 21 ) extension Mag . on film × 0.3 Mag . on page × 1
Revealing the anatomy of a water snail A I waited until the flattened shell of this freshwater ramshorn snail was parallel to the film plane so that I could get the entire shell , the head and the tentacles in sharp focus . By using a pair of electronic flashes , each angled on to the back of the snail , I was able to show how the mollusc's body spirals round inside its shell . The dark patch is the snail's heart . Lens 55mm micro - Nikkor Mag . on film × 2 Mag . on page × 6
Dramatizing a writhing worm
The only way to show the long writhing tentacles and the red feathery gills of this marine worm was to place it in a shallow dish over a central hole in a small table so that I could light it underneath by means of dark field illumination . I used two small flashes angled up from below to arrest the movement of the tentacles ( see set - up in diagram on p . 55 ) . Lens Hasselblad 80mm + 97mm ( 55 + 21 + 21 ) extension Mag . on film x1.25 Mag . on page × 5
