Excuse me, is this a photographic lamp? What's the effect?

This is a photographic lamp, which does not need a special lamp holder, and is no different from ordinary lamp holders. Generally, E27 copper lamps are nickel-plated (rust-proof).

But the genuine photographic lamp should be marked with the excellent temperature value. Usually, this kind of lamp should be 5500K, which is close to the color temperature of natural light. Do you have an excellent temperature mark on this lamp? Please check the back carefully. Anyway, the front can't see it.

note:

What is color temperature? Color temperature refers to the color change that human eyes feel under different energy light waves. Generally speaking: to what extent a piece of black iron is heated, the temperature value is the color temperature value, which is expressed by K! When sunlight shines 40 degrees above the horizontal line in a cloudless atmosphere, the color temperature is 5500 K. In 1983, the World Organization announced the ether sunlight as a standard to measure the color reproducibility of camera lenses.

By the way, I attach some common sense of photography for your reference:

1. "Is the brighter the photographic light, the better?" Many customers require to shoot products with 100W 150W 300W bulbs. Think that the brighter the light, the better. This is not entirely correct. The brightness of a photo depends on the aperture size and shutter speed of the camera. The brighter the light, the faster the shutter speed, and the camera will not easily blur the picture because of camera jitter. But you are shooting a still life. You only need to fix the camera with a tripod, and the effect is the same. So the light is bright enough. Two professional light bulbs of115w or135w are enough for general small product studios to shoot. Of course, if you want to take a portrait, or need to hold a camera for special reasons, it is recommended to shoot with a brighter light bulb.

2. "The picture is not bright enough, and the picture is too bright. Is it because of the brightness of the light bulb? " When all cameras encounter light-colored backgrounds or objects, there will be errors in metering, resulting in underexposure and darkening of the picture, which has nothing to do with the brightness of the light. Therefore, it is necessary to use the exposure compensation function of the camera to add one block or more. On the contrary, when encountering dark background and objects, it will cause overexposure, as long as the exposure compensation is reduced. Is the coordinate, "+"tone is to increase the exposure compensation, "-"tone is to increase the exposure compensation. The general symbol is "EV+-0".

3 "Are the three primary colors photography bulbs?" Tri-color lamp means that the fluorescent powder inside the lamp tube is composed of three kinds of fluorescent powder that can emit red, green and yellow light, and the light emitted is close to white light, which is more "comfortable" visually than ordinary ones. Therefore, most of the current energy-saving lighting bulbs are tri-colored, which is the case in most local small commodity markets and supermarkets, but the color temperature of this bulb is generally 6400K, and there will be color difference, such as white, which is light blue. You need to adjust the white balance of the camera or later. Professional light bulbs don't. This is mainly a matter of color temperature. The color temperature of professional light bulbs is controlled at 5400-5500K K. Professional light bulbs are only available in the professional photographic equipment market. So ask when you buy it.

4 "How to use the reflector well?" The reflector is very useful for shooting products. The black reflector will produce beautiful reflection. The reflection is obvious and beautiful. The white reflector can reflect light, and at the same time, you can get weak reflection, which makes the bottom details of your product better displayed. Many sellers shoot reflectors, which are either overexposed, the products have no details, or the exposure is not gray enough. Hehe, actually, the reason is the problem of exposure compensation. I only know the second point above. In addition, the reflector is easy to scratch, so use it carefully and don't drag anything on it. Cover with plastic wrap after use and keep away from other useless light sources, including windows. Illuminate with a photographic lamp, so that the reflector and your products are in the brightest position, so that other messy things will not appear on the reflector.

5 "Why is my picture unclear and so blurred?" The shake of a handheld camera will blur the picture, so a tripod is needed. It's best to use the camera's self-timer mode again, because the camera will shake when you press the shutter by hand. Try the self-timer mode, that is, if you press the shutter, the camera will shoot automatically after a few seconds, so as to avoid blurring caused by shaking the camera when you press the shutter by hand. For shooting small products, the camera can use macro mode and point focus. This will make the picture more detailed.

6 "How many pixels does the camera use to shoot? Is the higher the pixel, the better the picture? " The picture taken by the camera is composed of pixels, which are the number of color points in the unit area that constitute the image. The higher the pixel, the more color points per unit area. Therefore, the larger the pixel, the finer the picture will be and the more it can withstand magnification. It's not the more beautiful the picture. When shooting, we suggest shooting with the largest pixel, so that your picture can stand the later cropping. But the pictures used on Taobao are usually taken by cameras with more than 5 million pixels. There is no need to pursue high pixels, according to their own economic strength.

7 "Which is better, a square studio or a round studio?" According to our usual use, we generally recommend using a circular studio. The shutter in front of the circular studio can be removed, and the size of the opening can be adjusted according to your own needs, which is not available in the square studio, and the opening can be photographed up and down, which is also impossible for the square studio. Light: the circular shed has no edges and corners, which can better refract light and make it shine evenly on the photographed items. However, the square shed is mainly square with too many edges and corners, so the light refraction will be affected to some extent, and the uniformity of the light received by the goods is not as good as that of the circular shed. Portable: A circular shed with a diameter of 50CM can fold six faces into a circle with a diameter of 50CM, and after being folded again, it is only 1/3 with a size of 50CM, which is very convenient to carry and collect. The square shed is 50CM on one side, and the length and width are 50CM after folding, so it can't be folded again. This is a big board of 50×50 cm. The bearing capacity is not as good as that of a circular shed. And the freight is more expensive.

8 "The picture is better after taking pictures with a SLR camera, and PS photos are not needed?" In fact, SLR cameras need PS more. The photos taken by ordinary civilian cameras are called finished products, which are already very beautiful, especially Sony cameras. The photos taken by SLR cameras have a lot of post-production space. This kind of picture will be very nice after PS. Of course, SLR cameras can change the corresponding lenses according to different needs, which is impossible for civilian cameras. Professional lens imaging is not as good as civil integrated camera. In addition, professional cameras need photographic knowledge. If the technology is not good, the photos taken are not as good as ordinary civil integrated cameras. If the lens is average, the effect is similar to that of a civilian camera. Therefore, when buying a SLR camera, it is recommended to consider your ability to bear the lens first (the price of the lens will be more expensive than the camera! ), the place where the picture is used, and your own photography knowledge and PS level.
