It’s been a long time since macro photography (or close-up photography) is one of the schools of photography that allows photographers to be able to describe the little things in everyday life, making ordinary things extraordinary. often. This is also an art school that allows the photographer to freely create any small objects around us, conveying a non-wall message to each viewer.
Up until now, due to the nature of macro photography, it has to be very close to the subject, so photographers will need to have specialized camera lenses for macro photography with a minimum focusing distance of only a few centimeters (for short focal length lenses) to a few tens of centimeters (for long focal-length telephoto lenses). Macro subjects will usually have an aspect ratio of 1: 2, 1: 1 or 2: 1 (the ratio of object images printed to the camera sensor), even lenses can give magnification. to 10: 1 or 20: 1.
Specialized and bulky camera lenses for macro photography
Of course, that’s when we talk about using cameras and specialized macro lenses, and for today’s smartphone devices, the main method chosen by mobile photographers is to use a lens. outside with magnifying lenses. But that was before the Galaxy A51, and now, mobile photographers, or even the average user, can get creative with the school of close-up photography with ease. , all we need is a Galaxy A51 with a separate macro camera.
Recalling a bit about camera parameters of Galaxy A51. Galaxy A51 is equipped with Samsung 4 main camera clusters including:
– Ultra wide angle camera 12MP f / 2.2, focal length converted 13mm
– 5MP f / 2.4 telephoto camera cum macro camera (minimum focusing distance from 3 – 5cm), 40mm equivalent focal length
– Camera depth measurement 5MP f / 2.2
Galaxy A51 includes a separate macro camera
Overall with this cluster of 4 cameras, users can fully capture many different types of photos from landscape, wide-angle landscape, portrait or street. However, within the framework of this article, we will focus and macro camera of Galaxy A51, because this is one of the first smartphones equipped with close-up capabilities, promising to become a trend. photography in 2020 to come here.
Galaxy A51 with 4 main camera clusters
However, to be able to maximize the effectiveness of the macro camera on the Galaxy A51 as well as get the best photos, we will need to pay attention to certain points when taking pictures with this macro camera of the Galaxy A51 , because with Galaxy A51, when users take close-up photos, we will not be able to adjust the focus area, unable to narrow the aperture or change the focal length of the lens.

Determine the subject to capture
First, to capture any type of image, we also need to determine who the object to capture is, what is or what animal. Close-up shots, too, the subject of macro photography will usually be something small, as small as possible, such as flowers, leaves, water drops or even insects. With such small things, through the macro lens of the Galaxy A51, they will become bigger and more specification than ever, giving viewers a different look and emotion than when looking through the human eye. normal.
However, because the macro camera of the Galaxy A51 has a wide viewing angle and a focusing distance of 3 – 5cm, so for ease, users should focus and static objects such as flowers, leaves, … by opposing With small insects (such as bees, butterflies …), we can hardly get close in the distance from 3 – 5cm to capture.
“Set up” the environment and reasonable light
To capture high-quality macro photography, photographers will often have to set up a separate shooting area with adequate lighting (if shooting in studio space), or use a light emitting device like a flash. , LED lights or LED lights mounted directly on the lens … to illuminate the object to be photographed. Because when we take macro photos, we need to narrow the aperture to prevent the depth of field (DOF) from being too thin, which makes it impossible to focus on the entire frame.
Artwork of the macro photography environment, which requires a lot of light
However, with the Galaxy A51 macro camera, users only have a fixed aperture and fixed focusing distance, so when macro photography is needed, ensure adequate ambient light for the image to have a quality Best quality, because in photography, light is the most important factor that determines the quality of a photo.
The Galaxy A51’s camera app provides a dimmer bar, but we recommend not using it, instead setting up the ambient light to get good quality photos. Best.
If you are not in an ideal light environment, do not worry, we can fully take advantage of the available light sources. Galaxy A51 gives users the option to use the device’s built-in flash to illuminate objects. If the flash of the device is not enough, you absolutely can use the flash of another smartphone (or flashlight), to light from different directions.

Use a tripod or burst mode
When shooting macro photos, the subject to be captured is very small, as well as the focusing distance is only about 3 – 5cm, so it is inevitable that handshake phenomenon when shooting or out of focus (out focus), to avoid This phenomenon, you can use a tripod (tripod) fixed Galaxy A51 again.

However, if you do not have a tripod to fix your camera, try using the Galaxy A51’s continuous shooting mode (by holding down the shutter button) to capture multiple frames at once, then filter out clear images. definition and quality. This saves you the time of having to take photos when the camera is shaky or does not focus properly. You can also use the Galaxy A51’s continuous shooting feature to slowly approach moving objects such as insects (bees or butterflies).

The final and equally important step: Post-production
Of course, after we have done all the work to produce a macro image from the machine, we will still need another stage of image processing, which is post-production. This step will make the above macro photo come to life with different color effects better suited to each object.

Software you can use to post-process photos such as Snapseed, VSCO … (on the phone) or Lightroom (on the computer). The default camera application of the Galaxy A51 also provides some basic color filters that users can apply during the shooting process. However, to ensure the best quality, we recommend users to take the original image and post-production to have more options.
The color filters are available by the camera application
And here is the result from the macro camera of the Galaxy A51:
Overall, the Galaxy A51’s macro camera is of relatively good quality, the image is not too sharp and has sufficient detail. This is acceptable because the Galaxy A51 is just a mid-range A-series smartphone for young people, and the macro camera only has a 5MP resolution.
However, if you know how to take advantage of what you already have and set up an ideal lighting environment, the macro photos from the Galaxy A51 can be completely shimmering and eye-catching, featuring objects. tiny through the macro lens of Galaxy A51 and become extraordinary.
