Photo

   It’s expensive to manufacture small lots of the device, because its price includes the cost of scientists and designers work, advertising, and trade mark-ups. In short, one has to put up with a high price. Moreover one should prepare for the fact that the brush will be repaid not at once. That’s why I consider a brush light a tool for enthusiasts, who seek in photography satisfaction of aesthetic needs.

   I worked only with one type of light brushes – halogen source of light. There are also brushes with pulsed light source switched to stroboscopic mode of operation. I have little experience of work with such kind of brush, and I didn’t like it: there were too many difficulties with exposition determination, too acute boundaries of a light spot remain after a flash.
