Hi Terry

The same applies really but if they are very overexposed and there is little or no highlight detail, perhaps decrease the indicated exposure so that the white LED starts to flash. The meter will do its best to match the density range of the paper to the negative, and the neg will still contain a range of tones even if it's very dense. It's the density range that determines the paper contrast and the meter will choose the exposure to place the densest tone on the highlight. You then adjust the grade to place the least dense tone at the black end of the scale.
