I will tell you about "how to take case photos of beauty care" in a series. This time, we will talk about "the best camera for taking case photos and the basic camera mechanism".

No matter how successful the procedure is, if you cannot record accurate before and after, it will lead to a loss of image of the clinic.
This time, we will tell you the points to be careful about when choosing a camera and the basic shooting method of the camera, which are indispensable for taking beautiful case photos at the clinic.

Three points for choosing a camera to take case photos

The first point to consider when purchasing a camera is where and how to use it. The right camera depends on whether you use it indoors, in the city, in the mountains or in the sea, or what you are shooting.

This time, there is a clear purpose of recording the before and after of the treatment, but the following three are important for that purpose.

1. Select a camera body that supports an external strobe

The camera body is large and can be divided into digital single-lens reflex cameras, mirrorless cameras, and compact digital cameras.
To briefly explain the characteristics of each, there are the following differences.

Digital SLR It is possible to shoot with high image quality, but it is large and heavy. A wide variety of interchangeable lenses.
Mirrorless Compact and lightweight with interchangeable lenses. Convenient to carry. The image quality is the same as that of a single-lens reflex camera.
Compact digital camera Small and lightweight. It does not require lens replacement and has a full zoom function, but it is not suitable for full-scale shooting due to its small image sensor.

Beautiful case photos can be taken even with a compact digital camera.
However, the difference with the camera function of smartphones is narrowing, and there is no merit to choose, so if you purchase a new one, you may exclude it from the options.

Furthermore, in order to make it easy to compare the before and after treatments, it is important to always shoot under the same light conditions. Therefore, it is necessary to shoot with an external strobe under the same conditions every time, but compact digital cameras and smartphones are basically not compatible with external strobes, so it is not suitable for taking case photos.

Mirrorless is recommended. Since it is not as heavy as a single-lens reflex camera, it is easy for women to handle, it can take high-quality pictures, and it can handle both natural light and strobe light.

2. Check the sensor size that affects the image quality

Before and after photos can be recorded as beautifully as they are taken with a high-quality camera. Therefore, check the sensor size when choosing a camera.

The camera has a built-in device called an image sensor that returns the received light to an electrical signal. Simply put, the larger the image sensor, the better the details of the subject can be reproduced .

Many people think that the higher the number of pixels, the higher the image quality, but it is important to select the camera based on the size of the image sensor rather than the number of pixels.

The main sensor sizes for single-lens reflex cameras and mirrorless cameras are listed below in descending order.

  • Full size (36mm x 24mm)
  • APS-C (23.6mm x 15.8mm)
  • Four Thirds (17.3mm x 13mm)

For example, let's say you took a close-up of your face.
If you have a camera equipped with a full-size image sensor, you can see each one beautifully when you approach the hair. The smaller the sensor size, the more ambiguous the image is for each hair.

Let's compare the image taken by a single-lens camera equipped with a full-size image sensor with the image taken by a smartphone.

The image is large even when taken with a smartphone, but the reproducibility does not reach full size.
Therefore, in order to take beautiful before and after photos, it is best to choose full size, at least APS-C .

3. Lens selection is important for taking case photos

When the purpose is to record before and after the procedure, it is actually more important to focus on the lens than the camera body.

Lenses can be broadly divided into two types: single focus lenses and zoom lenses, but when shooting before and after, standard zoom lenses from wide-angle to medium telephoto are the best . Single focus lenses are not suitable for recorded photographs because they are easily blurred.

With the standard zoom, it is possible to take pictures in the hospital. Even for photos that require facial parts such as eye-ups, you can take a photo with a zoom lens close to a certain extent and then crop the photo.

Difference between single focus lens and zoom lens

Single focus lens A lens that cannot be zoomed. You can take pictures with the attractive bokeh and brightness of the image of a so-called single-lens reflex camera.
Zoom lens A lens that allows you to freely zoom and adjust the angle of view according to the distance to the subject. The types of lenses are divided according to the zoomable range such as ultra-wide-angle, wide-angle, medium telephoto, and telephoto.

Furthermore, the zoom lens has the following features.

Main features of zoom lens

Lens type Focal length Feature
Super wide angle 24 mm or less Recommended for landscape photography, etc.
Wide angle 24-50mm Mainly used for snapshots
standard 50-60mm You can take pictures that are close to the image you see with your own eyes
Medium telephoto 85-100mm Recommended for portraits as it has no wide-angle or telephoto effect.
Telephoto 135-300 mm The feature is that it appears closer than the actual distance.
Recommended for shooting distant objects such as children's athletic meet and airplanes

Recommended camera for taking case photos

In conclusion, the camera for taking beautiful before and after records of the procedure is a mirrorless camera equipped with a full-size image sensor. Of course, if there is no problem with the budget and the size of the main body, a single-lens reflex camera is OK.
The sensor size is full size. For the lens, prepare a zoom lens with a focal length equivalent to 24-105mm.

Basic camera installation 4 points

In order to take good pictures with a digital camera, let's know the basic mechanism of the camera. There are four points to keep in mind.

  1. Lens aperture (f value)
  2. shutter speed
  3. ISO sensitivity
  4. White balance

While explaining each one, let's check the settings when taking a case photo.

1. Lens aperture to adjust bokeh

The hole in the lens is called the "aperture" or "f-number". When this is fully open and vacant, the amount of light taken in is large, and the most blurred pictures can be taken.
The smaller the hole in the lens, the smaller the amount of light that is taken in, and the less blurring the lens becomes, the more the focus becomes.

For example, there are f-numbers such as f1.4, f5.6, and f11, but the smaller the number, the more blurred it is, and the larger the number, the more the focus is on the whole.

Image taken with f1.4
Images taken with f1.4 have a large background blur
Image taken with f16
The image taken with f16 has an impression that the whole is in focus and crisp.

When taking a case photo, first take a f-number of f8 and check it.

2. Shutter speed to adjust the brightness

The shutter is normally closed, but when you press the shutter button, it opens and closes, and this opening and closing time is called the shutter speed.
When the shutter opens, light enters through the lens, and the longer the time, the brighter it becomes.

For example, shutter speeds include 1/15, 1/60, 1/125, and 1/500. The smaller the denominator, the longer the light transmission time, and the larger the shutter speed, the shorter the shutter speed.

The smaller the number, the longer the shutter will be open, which may cause camera shake. Therefore, when taking a treatment photo, it is recommended to take a number larger than 1/125 .

Comparing the two pictures below, you can see that 1/125, which has a faster shutter speed, has a clearer outline and less camera shake than 1/15, which has a slower shutter speed.

Image taken at shutter speed 1/15
Images taken at a shutter speed of 1/15 will have some camera shake.
Image taken at shutter speed 1/125
Image taken at shutter speed 1/125

3, ISO sensitivity that determines brightness

ISO sensitivity is the sensitivity that determines the brightness of a photo from the light stored in the camera with the aperture and shutter speed.

For example, even if you set the f-number of the lens to the brightest and fully open and the shutter speed to 1/125, which does not cause camera shake, in a place with little light such as a dim place, it may become dark.
If you increase the ISO sensitivity number here, the photo will become brighter.

The basic ISO sensitivity is 100, and from here it doubles to 200, 400, 800, and the higher the value, the higher the sensitivity.

Comparing the photos below, you can see that the higher the ISO sensitivity, the brighter the photo.

Image taken with ISO100 set
Image taken with ISO100 set
Image taken with ISO200 set
Image taken with ISO200 set
Image taken with ISO400 set
Image taken with ISO400 set

For case photos, we recommend an environment where you can evenly hit the place where you want to take a bright light such as a fluorescent lamp. In such an environment, that is, when taking a case photo, try taking it with the basic ISO100 and check the brightness .

4, white balance to adjust white things to white

White balance is a function that adjusts white objects to be white.

Have you ever seen a photo taken under a light bulb appearing orange or a photo taken under fluorescent light appearing blue-green?
In such a case, adjust the color with white balance.

If it has an auto white balance that is similar to that of a single-lens reflex camera or smartphone camera, it will automatically reproduce the correct color.

If the color does not look right, try changing the white balance settings such as sunlight, light bulb, fluorescent light, cloudiness, and shade to balance the color.

When taking a case photo, set "Fluorescent light" if the room is illuminated only by fluorescent light, and set "Bulb light" if the room is illuminated in orange .

Set the white balance according to the type of lighting in the room you are shooting.

Easy setting to take a case photo without a mirror

I briefly explained how the camera works, but operating all of this manually is quite a hurdle, isn't it?

So, let me tell you how to take a simple and beautiful mirrorless camera that is suitable for taking case photos of the procedure.

Utilize "Aperture Priority Auto"

That is to utilize a mode called "aperture priority auto".
This is a mode in which the camera determines the shutter speed once the aperture is determined.

In the case of indoor fluorescent lamps such as case photos In the case of natural light such as sunlight
Lens aperture (f value) First shot with f8. Adjust the value if the subject is out of focus.
shutter speed Set to "Aperture Priority Auto" mode
ISO sensitivity First shot at 100. If the shutter speed is slower than 1/125, increase the ISO sensitivity and adjust.
White balance Set to fluorescent light (or light bulb) Adjust by looking at the balance

First try shooting with f8, and adjust the aperture value if the subject you want to shoot is out of focus.

If the shutter speed becomes slower than 1/125, increase the ISO sensitivity and adjust.

Basically, you can shoot beautifully with this, but if you can not shoot with the desired brightness, use a function called "exposure compensation".

Consider the brightness automatically measured by the camera as 0, and if you think it is a little dark, you can add exposure compensation, and if you think it is too bright, you can set it to minus.
