When starting out, be easy on yourself. Choose an object that remains still. Yes, those insects make really cool shots and maybe they are the whole reason you are looking for a Macro Lens. But your first shots should focus on something like fruit, flowers or coins. Nothing with legs or wings.
Certain subjects you’ll want to keep your distance from. To avoid getting stung by a wasp but still get that intense close-up shot, use a lens that is 100mm. 50mm lenses are perfect for still objects like coins or flowers.
You’re not only magnifying your shot, you’re also magnifying any motion. If you’re outside shooting foliage, even the gentlest wind can mess up your picture. Simply putting a stake in the ground can help keep your plants rigid and in focus.
It’s tempting to chase that dragonfly through the gardens. It won’t work though – after all, it has wings. Be patient. Some insects are as interested in you, as you are interested in them.
Sunlight in the morning can help you capture the minutest details, like the little hairs on an insect’s legs.
Be aware of where you’re standing and make sure that you and your camera don’t cast a shadow on your subject.
Keep your composition as simple as possible in order to limit distractions. Keep the focus on your soon-to-be stunning shot.
