Tools for image setting: Uber gradation curves and exposure adjuster

From the sound values collected by the sensor, the pictorial sound value of the subject must be used from the shadows to the lights and thus implemented in a RGB format that the desired image effect is achieved on the output medium used (monitor, paper image). So skin sound should appear in a matching brightness and color, shadow dark and full, or even well-tuned when interesting motive parts are there – but still it should look like shadows.

To gain an effective picture from the sensor’s linear raw data, requires different transformations.

Lights are to be reflected bright but not eaten. The middle areas should be contrasting, but it may be that you want to try to look from an interior through the windows, both details in the darker interior and in the brighter abs area recognizable and "Naturally" so that the interior and the subar area argue in the middle of the well-lost tonal values in the middle. An example is the recording in the Lindenallee – here it comes mainly on the tonal values of the faces in the shadow area, which has no full review between the tree in the background translucent in the background.

Many ways to the destination

In this recording in a Lindenallee, the center and skin sound of Duster and BlueGrun seem to arouse – despite "automatic female adjustment". Wedge-shaped manual corrections in the RAW converter.

On the user interface of the photo programs you will find two different models for controlling the sound value conversion: directly manipulated gradation curves, which represent a mathematical XY function in a two-dimensional coordinate system, and sliders that season or stretch the tone values on an imaginary horizontal axis (which is actually just one More comfortable way is to charge the shape of the gradation curve).

The approach with the gradation curve is very flexible for the expert and allows almost all manipulations in a tool. For the unchecked beginner, the effect is difficult but difficult. But the function of the sliders must first be understood, the name is not always clear, and there are now those who do something completely different than just the gradation curve!
