+1 Allows 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 intervals. This card is inexpensive, but failing to replace it will make the readings untrustworthy.
