Gopros are great action cameras, but almost nobody would think that the gopro is good for shooting macro video. These include the Nikon Coolpix line, the Panasonic Lumix DMC-LX3 and FZ38 with Raynox lenses, the Canon SX20is with Raynox lenses, and believe it or not a modified gopro. The quality of the macro video on many of these models is mind-blowing, considering what you needed 10 years ago for the same shots. There are several cameras on the market that shoot great macro photographs and HD video. Often, camera companies pride themselves on particular line of camera models that shoots great macro (like COOLPIX). However, we present a few to help you get started in your research. Finding a Cameraīy the time you read this, these camera choices may already be outdated. When you’re shooting flowers, you’ll probably want the center of the flower in focus, but then again, it all depends on what you’re highlighting. Most of the time, you should focus on the eyes of the organism, because the eyes are what humans tend to look at first when we look at an animal. While it isn’t necessary to use a tripod when you’re doing macro-photography stills, you will need a tripod for video to stabilize your shot and make it look professional. However, the color of your background will be seen, so try to choose a color that offsets or compliments the color of your composition. Backgroundsįor the most part when you shoot macro video, the background will be blurred. If it was crawling toward you, chances are that only part of the snail would be in focus at any given time. For example, you might choose to shoot a snail as it’s crawling perpendicular to the camera. The composition of your macro video is extremely important when you are working against your shallow focus and trying to angle the animal to maximize the area in focus. To get around this we suggest using a ring of LED lights around the lens. Direction of light: Macro video is taken extremely close to the subject, so much so that the camera may get in the way of the incoming light.Doing this will decrease the glare that shiny objects might reflect. A great way to get diffuse lighting is to construct a paper cone around your subject and direct the light evenly toward the paper. Type of light: While many shots might demand direct, contrasty light, we like diffuse lighting.We had to get creative with that shoot by changing our light type to a cooler LED. We did a shoot once on tiny, endangered snails that couldn’t be exposed to the heat produced by intense halogen light. It’s not always possible to get the maximum intensity. Amount of light: The subject should have as much light as possible on it. ![]() Light is extremely important in macro video work when you’re trying to get the largest depth of field. This increases the depth of field but means you’ll need a lot of light! Small apertures mean you’re shooting through a pinhole. For example, f22 is more desirable than f1.4. How do you increase the depth of field? Decrease the aperture (the size of the opening in the lens) by increasing the f value as seen on your camera. To keep the animal in focus you have to be creative with light and composition. The aim is to get the largest depth of field possible at a small scale. While this can be a great effect, it may not be your intended result. For example, you may get only part of an insect’s eye in focus. The first major obstacle in shooting macro video is that the depth of field becomes extremely small. Things to think about with macro video Depth of Field That’s why I made this short tutorial on shooting macro video. Few have summarized the best cameras and techniques for the job. In our search for reference material, we found that the Internet is full of very bad information on how to shoot macro video. But thanks to new technology, the resolution of photographs and video are high enough to work around that. Purists will explain that you can’t shoot macro unless you’re able to reproduce the image 1:1. A photograph can be taken hand-held, but a video cannot. It’s extremely difficult to get the same amount of light constantly on a small subject. ![]() You need a lot of light to take a macro photograph, with big strobes. ![]() The main difference is in light acquisition. Filmmakers that come from a photography background will quickly learn the basics if they’ve spent any time studying or shooting macro photographs macro video is basically an extension of macro photography with only a few differences. Macro filmmaking is the art of taking video of very small things.
