Today there are four families of digital cameras, each corresponding to a different user profile and growing budget. From compact to SD card bridge camera to hybrid, they are all easy to use thanks to preset automatic modes. The digital SLR is reserved for the very informed amateur.
Four main families of digital cameras
The compact camera stands out, as the name suggests, by its small size. It fits in a pocket, has an optical zoom that magnifies from 3 to 15 times and costs no more than 150 €. Also you can go for the canon g7x mark ii screw now.
The SD card bridge camera is larger, it costs between 150 and 350 € but offers a more powerful optical zoom (30/40 x) while remaining easy to use. These two types of devices are intended for users who do not want to bother with technology. Position On, automatic mode, successful photo. Hybrids and SLRs that are more complex to use require a higher budget not only when purchasing the device but also to acquire new, interchangeable lenses.
The centerpiece of a digital camera is its sensor. There are two types, CCD and CMOS. The second is replacing the first because it allows better shooting in low light and consumes less power.
An entry-level compact camera will offer 12 MP (mega pixels) or 12 million points per photo, a semi-professional 20 MP camera.
The difference: the ability to enlarge the photo and zoom in on details. The optical stabilizer is the other important option. Indeed, the more you use the zoom of the camera, to photograph a distant subject for example, the less the photo will be sharp, the stabilizer allowing to attenuate perfectly the blur.
Focus
It consists in adjusting the sharpness of the image, so as to obtain the desired visual result. Focusing can be done manually but many cameras offer an automatic approach to get your shots for sure. The latter can be set specifically for an object or more broadly for an architecture.
The focal length
This parameter is similar to the viewing angle of the lens: the smaller the number (in millimeters), the wider the viewing angle, and vice versa. When photographing a room, we generally rely on a short focal length (between 16 and 22mm).
Isometry
This involves measuring the sensitivity of the digital sensor; the higher the value, the more sensitive the sensor to light. Ideally, the sensor should be set to a low isometry of 100 to achieve better photographic grain (or digital noise). On the other hand, if there is a lack of brightness, the ISO parameter is increased (to a value greater than 100).
The source file
It is better to shoot as a RAW file rather than a JPEG. The difference mainly occurs in the editing, since the RAW file keeps all the information of the shot where the JPEG compresses the image. However, these are large files (around 20 MB), useful for working, but which should be converted to JPEG later.
Colors
In the context of real estate photographs, artificial colors should be banned, in favor of more realistic colors. This adjustment can be made automatically, which is sufficient most of the time. If necessary, it can also be done via the box; to do this, we will adjust the white balance using the “WB” button on the device.
