+1 allows for warm reflective reading with included blue cards
+2 mostly in Raw mode only due to small size of grey patch
+3 designed to be used in RAW mode editing, grey card available in small and extra-small
+4 RMImaging uses a 33% reflective card.
+5 You need to move to subject position to evaluate the exact amount of light in studio setting
+6 The Kodak grey card needs to be changed for a new at regular interval. This card is inexpensive but failing to replace it will make the readings untrusworthy. |
