Figure 4.2: ITP’s live image review system can operate in a number of analysis

modes. This diagram shows the eﬀect produced by each of these modes

on a sample image.

• Similarly, the shadows mode (S) emphasizes the detail contained in

the shadow regions of the image by expanding the lower values across

the entire range of the monitor’s display. This allows you to quickly

see the eﬀects of noise on the image and how much detail is present in

the deep shadows.

• Finally, the false colours mode (F) activates a special analysis func-

tion that recolours the image based on the exposure values at each pixel.

Extreme shadows are shown in blue, extreme highlights are shown in a

scale from yellow to red (red being fully saturated, yellow being on the

threshold, etc.). Pixels within the nominal region are shown in pure

green. As such, this mode allows you to see the distribution of light

levels across your image and see exactly where exposure problems may

occur - unlike a histogram, it provides context to the data and allows

you to determine if the at-risk areas are important or not. This system

allows a photographer to quickly glance at their studio monitor, deter-

mine exactly how their current exposure will eﬀect the ﬁnal image and

immediately make any necessary adjustments.
