separate purchase. Measured data from industry-standard
targets can also be manually entered in the software or meter. Upto ten camera profiles can be stored in the meter. Any number ofprofiles can be stored with the software. Once loaded, theSekonic L-478 series can make incident and reflected lightreadings that are precisely tuned to the dynamic range of the
profiled camera. A wide range of in-meter adjustment as well ascomplete exposure data input is also possible using the graphicinterface of the L-478 series.
