Useful accessories
- I use many of the accessories illustrated on these pages to aid my close - up photography both out of doors and in the studio . Some , such as the striped cable release , plant clamp , filter wrench , filter holder , light meter , right - angle view finder and white Lastolite reflector , are kept permanently in my backpack which I use for carrying my equipment on lo cation . In addition , I also carry a set of watchmaker's screwdrivers , a lens clean ing brush , spare batteries for cameras and flash guns , glass filters in filter stacking caps and a pocket tape recorder.
When working on location I keep all my films - both exposed and unexposed in a double - layered cooler box with a freezer pack . If I cannot find a shady place for the cooler box , I cover it with layers of old sacks and boxes . In hot humid cli mates films should be kept as dry as poss ible , preferably by laying them on dry ( blue ) silica gel crystals in an airtight box .
In my automobile keep old plastic bags for kneeling on wet sand or boggy ground ; a large umbrella for protecting the camera and tripod during rain showers ; a pair of waders for walking out into rivers to photograph aquatic plants in mid stream ; and I find a pair of gardener's knee pads useful for protection on hard rocky ground.
If you are walking any distance out of doors you must find a convenient method of carrying all your equipment . When working only a short distance from the automobile , or any other base , I find a photographer's vest very useful for carry ing a limited number of lenses and accessories . When working on snow or a wet beach , or in water where it is imposs ible to put equipment down on the ground , a vest is invaluable . Everything comes easily to hand without having to return to base to change a lens or retrieve a forgotten filter . A shoulder bag with a single shoulder strap is not comfortable or practical when I am walking any dis tance over rough ground ; so I always use a backpack which cannot slip off my shoulders should I fall . Smaller packs attached to a belt are useful for carrying a basic kit including a camera with one lens , extension tubes , a cable release , films , filters and a piece of aluminum foil as a reflector . Some wide camera straps have elastic loops for holding up to three 35mm films . If you are doing a lot of tripod work , a camera strap can get in the way , so it is worth getting one with quick - release clips .
I have often found through bitter experience that it is the small item which proves to be crucial to achieving the desired picture . This is why I now use a fisherman's tackle box ( see p . 154 ) which is divided into compartments . This houses such essential items as multiple flash connectors , extension leads , slave units , inch to inch conversion inch conti bushing ( for converting a nental tripod socket on a camera to a 1 inch ) , flash ball and socket heads , lens socket heads , lens reversing ring , model ing clay , a pair of scissors , string , clear scotch tape , and 2 inch wide rolls of scotch tape in white and black for taping down anything from electric cables to flash extension leads .
Photographer's vest
This Bulldog vest has 15 pockets , including four large front ones , two of which are padded .
Ewa - cape rain cover ▷ This transparent PVC rain hood covers the camera completely . The lens flap folds back for photography .
Plant clamp A home - made clamp with two spikes one is pushed into the ground and the other steadies a stem .
Conspicuous cable release
I have lost many cable releases outside , so I now mark them with bands of colored scotch tape .
For use inside and outside
Interchangeable screens
Plain matte
Gives a clear overall image for close - ups .
Cross - hair matte
Good for photomacrography and photomicrography .
Matte with fresnel
Good for lenses with small maximum apertures - 120mm f4 Medical - Nikkor .
Ground glass with double cross - hair reticle
Gives a bright image in dim light . 1mm increments aid magnification determination .
Check pattern , matte with fresnel
Horizontal and vertical lines aid critical copying work .
Filter wrench
These plastic filter wrenches can be used on any sized filter from 48 58mm in diameter . One wrench can loosen a filter jammed onto a camera lens . while two wrenches will be needed to separate one filter from another or a filter from a close - up lens .
Gelatin filter holder
This filter holder screws into the filter mount of the lens . It has a safety catch which secures the gelatin and holds it flush with the front of the lens .
Meter mate
By fitting it into the lens filter thread , this inch disk of translucent white . plastic turns a TTL metering SLR into an incident light meter . Hold the camera so that it reads the light falling on the subject .
Luna - six light meter
This sensitive light meter is useful for metering . low light levels .
Mirror on stand
Sold as a still - life . accessory , this 2 inch . diameter mirror can be used to reflect light onto shaded parts of a tiny subject .
Viewfinder accessories > A right - angle viewfinder gives an unreversed 1 : 1 image of the full viewfinder field . It can swivel through 180 for awkward angles . but normally it is used in the upright position . The eyepiece magnifier aids precise focusing by giving a x2 magnification . For viewing the whole field , flip it up on its hinge .
Spirit level
This fits into the hot shoe to check vertical or horizontal levels .
Reflectors and diffusers The Lastolite reflector springs open from its twisted form , stowed in a compact 14 inch pouch . to a full 40 inches in diameter . Use a gold one for warming up colors , a silver one for cooler nues , or for normal colors , use the white one . which can also serve as a diffuser to soften harsh direct light . The faceted Balcar diffuser breaks down into two components : any number can be used to build a light box or even a complete wall .
For use inside Photo jack
This is a support to keep books level for copying , or for bringing a specimen . into focus for overhead photography .
Clamp stand
A clamp stand will support specimens , fiber optics , small flash guns , backgrounds , reflectors , etc.
Focusing slide
The dual axis stage of this slide allows front , back and sideways camera movements .
Intervalometer
This triggers a motorized Hasselblad at intervals from 2 sec to 14 mins .
