Crop Area • With the crop node a ‘crop area‘ photo can be specified by the x/y-size and the origin of the crop box in relation to the original image. By selecting a projection aspect ratio (e.g. 1.66) in the ‘output format’ node the maximum appropriate ‘crop area’ settings are adjusted automatically and, if necessary, the image is auto scaled to fit into the chosen ‘output format’. By default the x-size of the crop box is set to maximum input image width and the image height is selecte

Crop box handling with the aspect unlocked: If the image should not be cropped in order to get the selected output format the ´lock aspect´ button photo can be switched off. This mode allows to only downsize the aspect ratio starting from the chosen ratio in the ‘output format’ node. The result is a horizontally- centered image with a letterbox on both sides. Check in the film view for the look. The projectable image height remains constant according to the chosen projection aspect rati

Deinterlace The ‘deinterlace‘ photo node enables the merging of two fields of video originated frames. There are no arguments required. • For quick comparison between ‘deinterlace’ on/off toggle key D in the processed view mode. Pushing down the key will disable the effect on the image and the color of the icon will change to black & white. For ‘effect on’ release the key.

CMS The Color Management system (‘CMS‘ photo) node is used to apply high quality profiles for standard devices such as Sony HD Monitor and Kodak Vision print stock projected by a xenon lamp in order to bring the colors of the film output close to what can be seen on the monitor. • In the ‘CMS‘ node a monitor profile (M) and a print film profile (P) is selected. For images with high saturated colors the soft clip can be adjusted by choosing one of the prepared soft clip settings from th
