I know there is an adjustment setting in the battery compartment of the meter but is there a specific method for calibrating the meter to the camera? The exposure seems to be so far off I'm not sure the meter can be adjusted enough to match the camera. Thanks for your thoughts about this.
One easy solution is to shoot a Photovision target using your camera's settings. When you shoot the target, you will get three peaks, one each for the black, gray, and white stripes.
I used my light meter settings to exposure. I then varied the exposure up and down in increments of 1/3rd É stops to maximum 1 É stop difference.
I loaded the images into Photoshop to see which exposure provided the most accurate reading. That is, which exposure had the gray peak in the middle of the histogram? In my case, the meter provided the correct exposure settings.
If I needed to use the "overexposured" image with a setting of 2/3rds É stop, then I would have known that the meter underexposed by 2/3rd É stop.
Hope this helps.
