1. Plan for success
Plan trips and become familiar with that work at different times of the year and for different types of species. Insect habitats include wetland, woodland edge and scrub mosaics with bare ground. Birch and willow often support larvae whose presence is given away by partially eaten leaves. Scan vegetation slowly for resting insects and view the same patch from different angles to double check.
2. Set the alarm clock
Insects are difficult to approach in hot weather so shoot during the cooler, early part of the season and get up early in high summer to find dew-covered specimens and adults emerging from their larval cases. Searching for butterflies that have settled to roost before sunset can save time the following morning. Use low back light during the ‘golden hour’ light to reveal wing-and-body translucence.
3. Stay local
Staying local means you can make the most of good weather. Become familiar with local nature reserves and research your target species beforehand to prevent wasting time searching unproductive habitats when conditions are ideal for photography. Gardens make excellent photographic studios: establish nectar-rich plant species, dig ponds, make habitat piles and leave rough unmanaged corners – all are great habitats for insects. Invest in a moth trap!
4. Watch the weather
Keep a close eye on weather forecasts and look for high cloud with light or no wind. The lighting in such conditions reveals surface detail and texture well, and you will also be able to use faster shutter speeds and smaller apertures for greater depth of field. If the sun comes out and you need fill-in flash keep it subtle; use low manual power because auto pre-flash can disturb wary insects.
5. Aim for clean and simple compositions
Shoot from a low viewpoint and frame your subject against a clean background wherever possible. If you need to move vegetation out of the way do it carefully and reposition plants afterwards so the insect remains hidden. As a general rule, align your sensor with the plane of your subject to get as much of it in focus as possible. A tripod enables precise adjustments; focus manually, use depth-of-field preview or use live view for critical focus.
6. Always aim for critical sharpness
Keep shutter speeds high (around 1/250sec) to ensure pin-sharp shots. Aim for reasonably small apertures – f/8 is a good starting point on a full-frame camera – but not so small that diffraction softening becomes a problem. Wind can cause subject movement, in which case increase ISO, use a wider aperture, or stabilise vegetation by using clamps on a small second tripod or ground spike. Alternatively get creative and shoot with a shallow depth of field through vegetation to create out-of-focus effects.
7. Try focus stacking
If the wind is light try focus stacking if your subject remains still. Some cameras have automated stacking functions that make this type of work easy from a tripod; alternatively shoot overlapping shots by incrementally rotating the lens barrel by hand. Stacking allows wider apertures, which can result in cleaner backgrounds. Process images with specialist software such as Helicon Focus and Zerene stacker; both are intuitive to use.
