Welcome to Tech Talk, a weekly column focused on the gadgets we use and their functionalities. We aim to keep things straightforward so that everyone can grasp how and why the device in your hand operates the way it does.
At times, things might get a bit technical, as technology tends to be complex and intricate. However, we can work through it together to make it comprehensible!
Understanding how it works, presented in a manner that everyone can grasp. Your weekly insight into the mechanics behind your gadgets.
You may not be concerned with how any of this operates, and that’s perfectly fine as well. Your tech devices are personal and should bring enjoyment. However, you might just discover something new…
One to one
You might have a specific macro setting available on your phone; many phones come equipped with this feature now. This doesn’t necessarily mean you possess a macro lens, but smartphones often defy the typical “rules” of photography, making it effective. If you spot the term “macro” or a small flower icon in your camera software, you essentially have a macro lens.
But what does it genuinely entail? Probably not what you assume.
A macro lens configuration is a technique for taking a 1:1 photograph. This implies that the size displayed on your screen corresponds to the actual size in real life. It doesn’t signify that the subject appears enlarged or that you can zoom in excessively; it simply means that the display size is “accurate.” While it may not be exact, it’s not advisable to use a macro photograph as an engineering drawing; it is, however, close enough for our eyes to perceive it accurately.
Imagine photographing an ant. When you direct your phone at an ant, you’ll end up with an image featuring a tiny black dot where the ant is located. Now envision getting a closer look, perhaps seeing its head. A standard camera configuration won’t achieve that, but a macro lens can.
Keep in mind that “the same size” is relative. We are discussing the viewfinder of your camera in this context. If I take a macro photograph of my angelfish as previously mentioned, the size you perceive while reading this may not correspond to what I saw in the viewfinder. What’s crucial is that the details are maintained, even at very close ranges.
A macro lens is essential for capturing all the minute details and preserving them when the photo is enlarged.
How does it function? Can’t I just use a “regular” setup?
At times, you might acquire comparable detail quality using a conventional camera lens, but generally, you won’t. This is due to the fact that a macro configuration isn’t merely a standard lens with close-focusing abilities. It’s a tool specifically designed for extreme close-ups and to operate seamlessly at the limits of visibility.
You’ll require a few fundamental hardware elements to begin. On your phone, some of these are managed through software, yet as stated, smartphones can bend the rules. What matters is that the setup can focus at very short distances, has a flat field to ensure the entire photo is sharp, and the capacity to adjust the focal length while altering anything else. Certain cameras can even extend to high magnifications, such as 2:1 or even 3:1, functioning almost as a microscope.
Most importantly, all of this must be optimized. Whether you possess a large full-frame camera paired with a $2,000 prime macro lens or a Motorola Razr (which features an excellent macro setting in its camera), none of it is effective unless it creates an image with the appropriate color, sharpness, and contrast.
Macro myths
As we all began to recognize the presence of a good camera in our phones, most lacked a macro setting. This led us to learn to adapt in incredible ways.
Now that macro capabilities have become standard, there are some persistent myths we should clarify.
Myth 1: Macro lenses are exclusively for small objects. False! Their remarkable clarity and flexible focal lengths make them ideal for portraits and general photography. An appropriate macro setup can indeed focus out to infinity while retaining a 1:1 view.
Myth 2: You MUST have a macro lens for ALL close-ups. Not necessarily. Consider food photography as an instance. You do not want or need to scrutinize every crumbly edge of Parmesan on your spaghetti. You can create an appealing and artistic photo with a standard lens, even at close proximity, if you’re willing to forfeit some of those minuscule details.
Myth 3: More light is advantageous. Not always. The quality and direction of light are essential. A macro photograph is one of the few instances where you might consider using flash to freeze motion and manage shadows. It’s important for the details to be clear and unobstructed while also being sufficiently bright to be visible.
Myth 4: Small apertures (f/22+) always result in sharper macros. Incorrect!
