Anonymous users2024-01-24The illumination of the 40W ceiling lamp will not be higher than 50LX, which is very dark for photography, and the exposure is extended to 1 2 seconds in time, although the granularity will be reduced, but there will be a color cast. So it's best to use a flash or a high-powered incandescent lamp.
See the article below.
Portrait photography under fluorescent and incandescent lights.
According to the characteristics of our Chinese skin, there will also be a piece of paper, light blue in front of the lens white balance adjustment as a benchmark, so that on the photo taken, the human skin (especially the face is ruddy) slightly color looks spiritual. In terms of determining the exposure value, if the light is evenly distributed on the set, and the brightness of the subject and background is about the same, the exposure is also automatic (with a bias towards the center average metering). If the average time distribution at the shooting scene is more accurate than taking automatic exposure, you can use the following three methods:
Zoned metering. Second, metering when in use. Third, use 18% gray board.
Use zonal metering.
The digital camera shoots a certain regular N partition of the picture, each measures the exposure value of these partitions, and the digital camera calculates the appropriate exposure value according to these exposure values, this exposure value is actually an automatic exposure, which is more accurate than the average metering.
Metering while in use.
Partial metering is about 2% in the center of the photographic frame, and spot metering can also be used instead of partial metering for some digital cameras. Partial metering of about 10% of the center of the image is about 10% of the local photovolt shooting, which can be used by photography enthusiasts for most of the shooting contents. When metering with spot metering and metering of local people's faces, the correct exposure value is obtained.
If your digital camera is zonal metering, spot metering, and the local area is also close to the subject, the face of the person captured with the digital camera is locked and the metering exposure value is returned and the place is shot.

Western restaurants all over the country basically have one characteristic: dim lighting. In this environment, either longer exposure times, wider apertures, or higher sensitivity ...... are required >>>More
In fact, it doesn't matter, mid-to-high-end machines + fixed focal heads, such as Canon 80D+50, 6D, 5DIII are better. Full width +35 fixed or macro is OK.
Because it is an indoor environment, it is recommended to set the ISO to 400-800 first, and the aperture should be opened as wide as possible (do not use the maximum aperture, shrink one gear), the shutter is automatically adjusted by the machine, and it is best to use a tripod under the conditions.
3 situations: 1, I just suddenly had the urge to capture... You can put it on a clean floor (flat or slightly up), use manual focus to focus in the middle of the depth of the furniture, measure the brightest and darkest furniture with spot metering, choose a compromise aperture (between) according to the brightest and darkest area, adjust the ISO to the minimum number, then cover the viewfinder (don't leak light from the back) and shoot 3 shots in a row with bracketing and go home to sift >>>More
When the camera is stained with oil fumes, it will absorb dust, which has an impact on the photo quality and the electronic parts of the camera.
