Often separated from amateurs, professional photographers are the lighting they master. Illumination can control the part of the image that draws your attention, or whether the appearance of an object is expensive or tacky. The lighting setup takes time and can even achieve the desired effect. An excavator rotating grapple is an attachment that can be added to an excavator to help with material handling. It is essentially a large claw that can be opened and closed to grab and hold onto objects such as logs, rocks, and debris. The rotating feature allows the grapple to rotate 360 degrees, making it easier to position and place objects in the desired location. This attachment is commonly used in construction, demolition, and forestry industries.

The era of digital photography has brought a new approach, known as "Lighting Design Computing." From Cornell University is still not easy, but the new software will give amateurs a good start, pros and cons save time .
This idea, mainly used for architectural and advertising photography, set the camera to use the flash on a tripod and walk around, firing it from many different angles to take a hundred or more exposures, each with slightly different lighting. Images in Adobe Photoshop are loaded into the "Layer" overlay, blended and layered to get the light you want.
Even for professionals, getting the right mix is ​​difficult, art is more than science, and sometimes it takes hours or days of skilled labor. Working with professional photographers - with amateurs - Kavitabala, associate professor of computer science, graduate student Ivaylo Boyadzhiev and Adobe research Sylvan Paris, later testing developed software, preloaded with many layers, divided into three A basic view, users can merge and modify. They described their work at the 2013 SIGGRAPH computer graphics conference in Anaheim, California on July 21 and 25, in Barra, California. She was inspired by such beautiful advertising photos and said: "You want your own product." The secret she realized was that it was lighting.
In the current version, the software will create three composite images, which the researchers call "base lights": edge lighting, emphasizing the shape of the object and its own shadow; filling in the light, illuminating everything evenly; and diffuse color light , bring out the color and texture of each object. The user can select the image, where applicable to different amounts of each area. For example, add more fill light to lighten the shadows. The results can be modified to focus sharper light in a specific area, or to simulate the effect of a diffuse filter on the light source. Advanced users may eventually return to the final adjustment with the original multilayer.
