Profoto D4 power box can be used in almost all shooting situations. Without sacrificing image quality. Digital control can achieve extremely accurate color temperature and aperture output stability. At the same time, for users of high-end SLR cameras and digital backs in Quan Huafu, D4 can perfectly match the accuracy of cameras and become the first choice power box. The technology adopted by D4 is far ahead of other brands and other models of Profoto products. Leading technology helps photographers to work and meet the demanding requirements of customers. It is precisely because of the extremely wide power adjustment of the power box (8 apertures, taking 2400 boxes as an example, 19, 36, 75, 150, 300, 600, 1200, 2400) that the photographer's creation is more convenient and relaxed. This is the height that other brands of power boxes can't reach. But at most, four lamp holders with completely unbalanced output can be connected and can be adjusted independently, so that a power box can complete a large part of shooting tasks. Figure 2 and Figure 3 above respectively represent the color temperature stability curve of D4 and the color temperature stability curve of two lampholders flashing continuously 10 times in the global energy output. In icon 2, the ordinate represents the color temperature and the abscissa represents the energy output from maximum to minimum. The green curve color temperature of the Profoto D4 power box is slower than that of the traditional red power box, in other words, the change from the maximum output to the minimum output color temperature can be ignored in the picture.

Chart 3 shows that when a power box uses two lampholders at the same time, the red line and the green line represent the two lampholders respectively, and they blink 10 times at the same time during the test. In terms of the color temperature of the ordinate, the two curves of the D4 chart almost overlap, reflecting that the color temperature of the two lamp holders is not basically constant. On the other hand, the color temperature changes greatly between flash heads in the following traditional processes.

Features of Profoto Pro-8 power box:

This electric box adopts many industry-leading technologies such as pipeline technology, so that the flash head is always on standby. The flash of 20 times per second makes the photographer more confident about the time to call back when shooting. What is worse now is the shutter continuous shooting speed of the camera. The friendly user interface makes the photographer's job easier, and he can master the control and use of the electric box in just a few minutes.
