Itis questionable which is to be preferred ;the former is the most powerful and moregenerally employed, but many workersmaintain that the incandescent system,properly used, will give softer and betterresults. A good deal depends upon thecurrent available, and the whole subjectis one for consideration not only from a POJITIIAITURE. 475 photographic point of view, but in thelight of advice from a practical good ariangement of the arc light forstudio use is shown by Fig. 606; themethod of swinging the concave reflectorto any angle, and the counterpoise whichbalances the arrangement at the desiredheight, will be noticed. Another excellentform is shown by Fig. 607. At A (Fig. 608)is seen a. rackwork contrivance whichadjusts the angle of the reflector.
