Anchor Points

As the transition point moves more left, the darker points of the image become more and more washed out. While some of this is desirable, we need to be able to control the effect a little more precisely. For this exercise, set the transition point at about 23, and add a new control arrow at about 13. This placement has the effect of anchoring the curve and allows us to control the stretching of the darkest shadows. Like the transition points, the placement of the anchor point(s) needs fine tuning.

Anchor points can also be used within the Sabattier effect area to control the effect, as well as in other places to limit unwanted ide effects of the transform. Do the basic manipulation first, concentrating on the transition points, then add and adjust anchors to control the effect within the transition points.

Some other points to be noted with this transition point setting

• Sky gradient has reversed and been exaggerated
• Seat and bike are now outlined in white
• Front mudguard/fender have reversed and become liquid
• Oil tank has become a little dull
• Highlight at front of fuel tank has become a black star outlined in white, very similar to a solarisation effect.
• Grass now very light
• Dark trees at the back of the bike have whitened, helping to give the bike shape as the saddle bag no longer blends into the trees. In my versions of the image, I removed some of these trees to better delineate the bike.
