Can anyone tell me the exposure latitude (range) of camera films in f-stops?
I've been researching this.. i've found suggestions that b&w negative film has a 7-stop latitude and colour slide (transparency) film has a 5-stop latitude, but am not sure if this is true or not.
If this is true, if I use my (colour slide film loaded) camera to take a spot-meter reading of something which is 18% grey (the grey that all lightmeters are calibrated to), and I set a 4 stop underexposure using the camera's exposure compensation feature, then the resultant slide will show that area to be totally darkest black. And likewise, the other way, if I overexpose the slide by 1 stop, this area should be brilliant white. Is this true?! This makes the 5-stop range for this film seem a little narrow from my experience. I am assuming here that my camera's inbuilt lightmeter is calibrated to 18% grey, and this is located 18% of the way between white and black, and not located at the midpoint (50%).
Ideally what i'd like to do, is to take a spot-meter reading of a tone, then shift the exposure using the exposure compenstion feature on my camera and be able to predict what the resultant tone will look like on the slide/negative.
I look forward to hearing any suggestions about this topic
