manaGinG exposure – usinG hiGh dynamic ranGe tool
The bulk of image adjustments can be done with the exposure slider and the levels/curves tools.
There are two scenarios where the High Dynamic Range tool may prove to be essential.
In certain situations, image contrast is such that clipping may occur at both ends of the histogram.
In such cases the HDR tool provides a means of optimizing the image to deal with the extreme
contrast and prevent the clipping of highlights and shadows.
High Dynamic range also provides the means to make use of images that have been accidentally
over or underexposed to an extent that render them unusable with conventional exposure tools.
How to optimize the dynamic range of an image
The dynamic range of an image is optimized at the shooting stage by adjusting exposure to capture
the maximum amount of data. This may result in an image that does not look optimal on the LCD
display.
Bear in mind that around 1/2 - 1 stop of additional data can be recovered from overexposed
highlights.
Once the image has been opened in Capture One, it is optimized by using the various tools within
the software to adjust the data. The High Dynamic Range tools can help with ‘difficult’ images, where
contrast is extreme. Applying a soft-proof profile for the output should be configured in order to edit
for this output device.
