Better Light 7 manual Static Spot Meter Location Readings

against the left (zero) side of the histogram, the image is probably underexposed, and will be dark. Likewise, if a signiﬁcant portion of the image data is above the desired value for highlight detail, the image is prob- ably overexposed, and will be bright. Data concen- trated near both ends of the histogram implies a high- contrast image, with little midtone, while a histogram with a narrow spread of data indicates a low-contrast image.

Whenever the spot meter is active, an indicator in the histogram display shows the position of the data value for the spot being read relative to the overall histogram; this feature can quickly relate speciﬁc areas of the image to speciﬁc regions in the histogram.

Static Spot Meter Location Readings

Whenever a spot meter location is saved, a set of circles in the preview image marks the location, and a color coded line in the histogram display marks the relative data value for this location. The circles are static and will remain in the same locations for sub- sequent prescans, until the meter is cleared. However, the color coded lines in the histogram will move to reﬂect any changes in data value for each marked loca- tion.

The data values for the marked spot meter loca- tions are displayed in the Color and Tone tab panels. The RGB values for each spot meter marker are listed next to their respective colored circle.
