Image Intensity and Contrast
With the top part of the 'Tools' window, you can adjust the intensity and the contrast of any photo window or the
'Scrolling camera view' window.
Note; Remember that any modification of the 'Tools' settings for a photo window is ONLY valid for that window, where
a modification for the 'Scrolling camera view' window will be valid for the 'Scrolling camera view' window AND all
following recorded photos.
Just move the slider in the upper bar to the right or to the left and the image will become respectively lighter or darker.
The image contrast is increased if the slider in the lower bar is moved to the right, and the contrast is reduced if the
slider is moved to the left. Both actions will be applied to all the colors present in the picture.
By clicking the small arrows on top of each bar (arrows facing down), it is also possible to return to the default (=
original) settings.
Here is an example of how you can manipulate a picture by means of the Tools window:
In the above series, the left picture was set to its default color intensity and contrast setting.
By sliding the lower bar to the right, we have increased the contrast of the picture in the middle.
In the right photo we made the picture lighter, by sliding the upper bar (a little bit) to the right.
Click the tiny arrows on top of each bar to return to default settings.
Tip; We recommend to use the standard setting (both sliders as close as possible to the middle position) for the
'Scrolling camera view' window, for the recording of new races!
RGB Color Calibration
The Red, Green and Blue on screen color calibration is a tool for color fine-tuning of the photo-finish picture.
To select the RGB color calibration function, click the little arrow facing down in the tools window, and the extension in
the tools window will appear (see right):
As you have noticed, the RGB color calibration is divided in both 'Offset' and 'Gain %'.
Offset can in fact be compared with the 'Intensity' function, be it that now you can adjust the intensity per separate color.
You can enter a value between -31 and +31 (decreasing or increasing the color components).
Gain (in %) adjusts the color contrast per color. It is an amplification or attenuation of each separate color. It is valid for
the entire picture. The 100% gain is a default setting.
Suppose we would get the following photo-finish picture on our screen after recording and for example, we amplify the
red color contrast by 265%, the green color contrast by 150% and leave the blue untouched. Just fill in these values in
the rectangles under Gain%:
