Regions

The softness of the top, bottom, left and right of the region can adjusted from the controls around the blue display on the transport panel. Additionally, the region can be tilted and skewed. These controls will automatically appear when the region position is adjusted.
To ensure smoothest edges, make sure that the DCP track ball ring is fully wound up. This should be the default. The edges for the first three channels can be changed by selected one of four different slopes. (F, S, M and H) or (Soft, Soft , Hard, Hard on Platinum).
These can be used to make the edge slope very quickly and make a more precise region. Normally for real scene isolations the first F position is used. However, artificial shapes like ovals, and circles can be made on the M or H settings.

To make a circle...

• Start with a rectangular region.
• Apply equal softness to all four sides.
• Reduce the size of the rectangle to nothing. (leaving softness)
• Click on the F/S/M/H button for the current channel.
  On "M" you should have a perfect circle, with a fair amount of softness.
  On "H" the edges will be harder, but probably not so suitable for normal scenes.
• Adjusting softness on each side will give different shapes like ellipses and semi-circles.

A colour wash or tint can be made in two ways. The easiest is...

• EXPAND a channel. This channel will change the whole picture.
• Desaturate, then use the gamma to add in the appropriate colour.

Sepia and other tints can be achieved by this method. Obviously by programming this as a mix a gradual change can occur. Also, the channel region controls can be used to apply the wash to a part of the picture, and the edge softening used to produce a graduated boundary between the background and the region. In this way the replication of camera filters, corals, ND's etc, is possible.
