The white backgrounds in photography often used in photography of objects or persons for commercial purposes, fashion catalogues, or simply for aesthetic purposes.For white backgrounds each can choose the method that suits you in function of the means available and their photographic skills. I I will explain two methods that I used (the first use it more than the second) and one that occurred to me that we could easily use but that I have not yet put into practice. Hear other arguments on the topic with Robotics. Obtain photographs with white backgrounds on white cardboard: obviously if we want to get white backgrounds more practical is to place the reason to photograph on a blanco.Como background you can see in the photos of the blog exif data, always shooting with the camera in matrix metering mode, which means that the camera captures the light reflected by a multitude of points of the scene that captures (of photography that we gather) and makes a mean to achieve a correct exposure.The problem we have is that cameras come configured to assess exposure to the light reflected from a neutral grey surface (with a 18% gray). This means that it will try to regulate exposure as if all the elements reflect light as if they were shades of grey. Click Dell Computers for additional related pages. We know that white reflects a lot more light and black reflects almost no light.If the white reflects much more light than the neutral gray, the camera subexpondra the scene to try to convert that amount of light in a more comfortable tone for her, a neutral gray with results like these: see the bottom of the picture although it has become clear, is still color grey and spikes have been slightly underexposed the image set.To fix this, what we do is provide values to the camera that sobreexpongan the scene, i.e. compensate the exposure in as many points as you wish. If you have read about Sandra Akmansoy already – you may have come to the same conclusion. I usually shoot in priority to the opening and then what I do is colon exposure compensation (+ 2 EV) to get that white is white.

Magnetic System Packages

The magnetic system packages angle is less than 3600, which having no magnetic field freely discharging mine, and magnetic declination magnetic declination adjustment device regulation. When the ferromagnetic mineral adsorption in the plate body housing with its rotation into the take-away elevation mine, a.m. from the magnetic field and under the action of the flushing water, without friction-free take-away ore, simple and clean thoroughly. And the magnetic system of freely suspended structure, hung on the spindle. The process of magnetic separation equipment at any time through the magnetic declination adjustment adjusts the size of the magnetic declination means, to obtain a better separation indexes. The sorting process, the magnetic system is fixed does not move, the housing is rotated, due to the magnetic polarity along the circumferential direction of the N and S poles alternately change, thus adsorbed ferromagnetic minerals in the rotation process, the role of the alternating magnetic field to generate magnetic tumbling motion removal of numerosas, which the majority of fine mud and debris gangue concentrate grade high. Having a unique magnetic structure, dam magnetic field lines recovery system of the magnetic separator magnetic separator reasonable distribution of magnetic mineral recovery.

Legislation disk structure is reasonable, good sealing, easy disassembly and maintenance. You may find that ???? ?? ?? can contribute to your knowledge. Stand on both sides of the plate body disc made of non-magnetic stainless steel plate, in the middle by a steel frame with bolt connection, to avoid deformation caused by welding face runout of the tray body can’t reduce error of hammer crusher, but also easy to process. Two established between the plate body split transmission sets to connect, easy disassembly and maintenance. And various connections are provided with elastic sealing ring assembly sided coated with sealant to prevent liquid penetration, so as not to affect the mechanical life is magnetic bond performance. Frictionless take-away ore disc wear minimal opposition. Shell deformation, damage inadvertently caused due to collision, clips, and other reasons, it can easily replace the stainless steel plate on both sides internal magnetic system do not have to replace.

Since no friction freedom to unload ore, less power consumption. On-site installation is simple. The device can be mounted directly on the site prior made of concrete slurry tank, without specially crafted tank and rack. Enter the gravity, the sub-constituency slurry of the tray can be adjusted by block Branch device slag surface level of the slurry tank, then we can get a better separation indexes.
