Using off-camera flash for macro

1.    Setting up

Description: setting up

Mount your camera on a tripod and set your flashes in place, either by mounting them on the lens or positioning them off-camera. Using two flashes is ideal for an even spread of light.

2.    Manual exposure

Description: Set your camera to manual exposure

Set your camera to manual exposure and choose an aperture no wider than f11. Use a fast shutter speed and fire off some test shots to check how the light is falling.

3.    Be precise

Description: Be precise

Focusing often presents a challenge at such high magnifications. Your camera’s autofocus may struggle, so focus manually instead. Precise focus is absolutely vital with macro.

4.    Check the shot

Inspect your shots by using the magnification button to zoom in to check that you have a correctly exposed, pin-sharp image. If not, check your focus and try a faster shutter speed.

Add a background

5.    Get gardening

Tuck or clip any unruly stems or leaves out of view. Unless you are in your own garden, do not pick any leaves or flowers – hide them out of view without destroy them.

6.    Insert a backdrop

Now select a piece of card and place it around 10cm behind your subject. You could also use fabric or a piece of board - just ensure it has a matte finish to avoid any nasty reflections.

7.    Add depth

Now set your aperture to around f11 to ensure your subject remains in focus and the background melts away into a blur, tinted by the colour of your piece of card.

10 expert shooting tricks

Macro-pro Dale Morris shares his secrets for bagging top shots.

1.    Shoot at the right time 

Insect and plant photography can be particularly rewarding in the early morning. The air is usually calm and cool, which means that plants are not swaying around and insects tend to be slugging (they only get going when things warm up).

Dewdrops are also prevalent in the morning. Harsh sunlight can ruin a photo so bring along a piece of card to create nice, eve shade over your subject.

2.    Use a polariser

Use a polariser

A polariser helps reduce glare from flower petals and also help boost colours in your shot. Just remember – it reduces available light, so you’ll need a longer shutter speed and a tripod.

3.    Lens hood

Remove the lens hood when photographing flying insects such as wasps and bees. It reduces the chance of your subject feeling threatened and either attacking or flying away.

4.    Your outdoor studio

Achieve a white background by creating mini studio on location. Light some white Perspex or transparent material from behind your subject. Then light your subject from the front with a reflector or flash for a perfect macro shot.

5.    Depth of field

Description: Depth of field

Use aperture priority and depth of field preview button to check your focus. It’s tricky to see depth-of-field preview when stopped down as the image in the viewfinder is very dark. Use a mini LED flashlight to see what’s going on.

6.    Use fill-in flash

Description: Use fill-in flash

To retain some background, set your flash to the slow or rear-curtain sync mode. It allows the camera to expose for the correct ambient light while illuminating the foreground with a small burst of light emitted just before the shutter curtain closes ( the end of the exposure). This will give your photos a more natural look.

7.    Make a macro lens

Join two lenses together, front-element to front-element with a simple macro-coupler adapter ring. The reversed lens should be a smaller focal length than the one attached to the camera. Turn off autofocus to reduce strain on the lenses’ mechanisms.

8.    Vary your lenses

Don’t limit yourself to just using macro lenses. Wide-angle lenses such as a 15mm or 24mm will still offer a minimum focusing distance of under 20cm, while giving you the opportunity to shoot your subject in more of their natural environment.

9.    Use a cable release

Description: Use a cable release

Minimise camera shake by using a cable release. Pressing the shutter can have ‘earthquake’-including effects on your shot so remove yourself from the camera. You can also use the camera’s self-timer as an alternative.

10.  Back away from your subject

Remove yourself from your subject’s ‘zone of awareness’ by using a longer-focal-length lens. Combine with a teleconverter a larger working distance and higher magnification.
