Digital Photography For Beginners - Explore The Larger Than Life World Of Macro!

Macro is an extraordinary twist on photography, involving tiny subjects up close and personal yet larger than life. This could be a small creature in its entirety, such as a caterpillar, or just part of one, like the wings of a butterfly. You can study diminutive subjects in a way you never could with the naked eye. You see the subject stopped in time and in microscopic detail. Seen in this way, you will be amazed at subjects you encounter daily yet hardly notice. There can be considerable challenges to meet in order to conquer this genre of digital photography, for beginners especially so.


To take successful macro photographs, you will need a digital single lens reflex camera (DSLR) with a macro setting. A point and shoot camera will not enable the lens to clearly focus on a tiny subject at the very short distance from the lens that is required to take a macro photo. In addition, most point and shoots do not allow you to add macro lenses or magnifying lenses to the existing lens on the camera.


A fine way to learn macro techniques is to practice with subjects that cannot crawl away or fly off. Insects make incredible subjects for macro photos, but they are difficult to capture. Instead, start with small objects, such as the parts of a flower, the detail on a coin, or a piece of jewellery.


The macro setting on a DSLR camera will give you a reasonably good macro image. Certainly, it will enable you to focus the camera on the subject much closer and with a much shorter focal distance than at other settings. Utilising the manual focus option will also enable you to capture detail other settings will not.


However, to truly appreciate the beauty and amazement of macro photography, you should utilise lens attachments that will allow you to get even closer and capture even more detail. A diopter - or close-up lens - that is threaded and can be screwed onto your existing camera lens is an excellent investment to take your macro photos to the next level. These close-up lenses come in increments such as +1, +2, or +3, meaning you will be able to see and photograph the subject 1 time, 2 times, or 3 times closer than without this lens.


The lenses have threads on both sides, so they can be combined by screwing them together, as well. This lets you stack them to obtain even higher-powered close-up effects. For instance, combining a +1 and a +3 lens will result in a +4 effect. Macro photography experts recommend you attached the higher-powered lens first and then add on the other diopters in order of highest power to lowest power. So in this case you would attach the +3 close-up lens first and then the +1 close-up lens.


One factor of macro digital photography for beginners to consider is that you may also need to use a teleconverter lens, which allows you to slightly back away from the subject and still get your shot. With insects that may move or fly away when you get close, this item will be invaluable. A teleconverter essentially magnifies the subject. A 2X teleconverter works well. At higher levels, there are mixed opinions about how effective teleconverters may or may not be, but a 2X allows you to gain the working distance you need. It also enables more light to fall on the subject without being blocked by the camera and lenses.


Macro photography requires good lighting, but on-camera flash is not the best source. It is better to turn off the on-camera flash and photograph the subject in a well-lit area. Photographing outdoors or near a brightly-lit window can provide good lighting. Alternatively, you can utilise lighting from other sources to supplement the ambient or available light. Practice in bright natural lighting before you invest in special lighting equipment for your macro photography.


The road to excellence in macro digital photography, for beginners, is not an easy one. But digital photography encourages experimentation, so practice mixed with perseverance should produce more than satisfying results.
