Small Mammal Photography

Most small mammals; mice,voles lemmings,jumping mice and shrews, are generally nocturnal. To photograph them they must be confined in some sort of "studio". The studio or enclosure could be a fish tank or a similar object. I built mine using Plexiglas made for the picture framing industry. The advantage of using this grade of Plexiglas is that it is clearer than the standard grade. If you decide to build your own be advised that assembling the tank requires a special glue that works with Plexiglas. The glue is generally available from paint, glass and hardware stores. The studio, or mouse tank as I call it, can be any size you want. The dimensions of mine are 8" wide x 16" long X 6" high. I would however recommend a height of 10". The first deer mice I captured were easily able to jump out of the tank before I could get the cover in place. My cover is made from the same Plexiglas as the rest of the mouse tank.

MOUSE TANK & VICTOR TIN CAT MOUSE LIVE TRAP

To obtain small mammal models you will need to live trap them. I have found that the Victor Tin Cat Mouse Live Trap is a perfect piece of equipment for the job. I spray painted mine with camouflage paint to make it less obtrusive when it is located in public areas.

Next you will need to research both the required habitat and food sources for the targeted species. The trap should be placed in the proper habitat and baited with a suitable food source. The trap should be secured to a log or tree trunk with a length of stout wire to keep larger predators from running off with an occupied trap, although it isn't likely. The first time I put out my trap I found muddy weasel tracks all over the top of the trap the next morning. I've wired my trap to a solid object ever since. Further camouflage the the trap with leaves and pieces of bark.

I put my trap out late in the day and check it early the next morning. I pick up the trap even if it is empty, then put it out again in the early evening so as not to confine the small mammal for too long a period. Once you have a "model" in your trap, cover the floor of the mouse tank with materials from the surrounding area. You may also want to include some preferred food sources for the model to eat. Transfer the small mammal to the tank as gently and quickly as possible and get the cover in place. I open the cover of the trap slowly over and very close to the top of the mouse tank. This method will force the small mammal to jump into the tank, then quickly get the cover in place. The mouse tank should be placed on the ground with similar ground cover as was placed on the bottom of the tank, as a backdrop.

Now for the final step, the photography. Before photographing allow some time for them to settle down. Flash will typically be required to stop the motion of these fast moving small mammals. I have the flash positioned off camera and a diffuser on the flash head. I tried using a 100mm macro lens but quickly discovered the field of view was too narrow when keeping the front element close to the side of the tank to prevent reflections from showing. After trying a few different combinations I found my 24-70mm lens coupled to a 12mm extension tube to be a just right. This combination allows me to zoom in and out to frame the composition I want while keeping the front element close to the side of the mouse tank. Setting the camera's exposure mode to manual while keeping the flash in auto mode, you can set the aperture for the desired depth of field while adjusting the shutter speed for the desired ambient light. Since most small mammals are typically crepuscular or nocturnal a slightly darkened background is appropriate.
