Hi everyone, My Gossen Starlite lightmeter died in a heavy downpour yesterday and I just purchased a Pentax digital spotmeter to replace it. After reading the manual online I observed that there is a table in there advising the user to adjust the index number based on the reflectance of the colour being measured. According to the manual, yellow has the highest reflectance and thus should be placed at '8' on the index number scale: leaving it at the standard index would result in underexposure. For purple and indigo colours the index should be set for 2 or 3. I wanted to know if anybody actually does this as I have not seen it mentioned in any thread that I looked through. I will be using the meter for Velvia as well as for b&w film exposures. Thank you everybody!
