The Development mode provides
effects that were applied in the darkroom when developing the film.
Clicking one of the preset
icons will activate the appropriate effect by setting the sliders below to certain
values. The same presets can also be found in Photography Mode, B/W Quick Mode
and Expert Mode. For more information about the presets, please read the Local
The Brighten slider lets you increase or decrease the brightness of the image in EV steps from -5.0 to +5.0. For many images you will only need adjustments between -1.0 and +1.0 though. It doesn't work like the brightness or gamma sliders that are known from many graphics applications. It doesn't cut off shadows or highlights and also doesn't change the contrast.
The Contrast slider does what its name suggests: It adjusts the contrast of the image. Values below zero can make some details more visible, but can create a more grayish look. Values above zero increase contrast and give the image more punch, but may make some shadow details less visible. If you deactivate the check box at the left, the Contrast slider is split up into two sliders, called S-Contrast and H-Contrast, for adjusting the contrast in the shadow and highlight areas independently. If both sliders have the same value, the effect is the same as that of the single Contrast slider.
The Amplify slider is meant to be used in addition to the Brightness and Contrast sliders. It offers further precision for brightness and contrast adjustments for difficult images. It performs a white point adjustment for positive values and a black point adjustment for negative values. Please use with care, because it can easily blow highlights or suppress shadows.
The two hyper links at the bottom let you switch to Photograph Mode or to Expert Mode. Alternatively you can also use the Mode combo box at the top for doing that.
