| Just a question-- there's a function on my photo program that says you can more or less create your own lighting on the picture. You click on the function and move the little arrow thingies around to create the desired lighting. You're not actually doing it to specific parts becuase it affects the entire picture. Is this legal? |

I don't believe this type of filtering would be legal in an open challenge.

I don't think so either. Behind the scenes, it is creating some kind of gradient or mask, or some pixels wouldn't be affected more than others.
It might be useful, however, to get an idea of how you could change your lighting set-up and re-shoot your subject. |

I say no as well because it is essentially an effects filter and of those types of filters only the Noise and Gausean Blur are permitted.

Isn't this the same as the PS 7/CS/Elements Lighting filter? Which I believe is not legal

| I don't think this is such a good idea! But you've heard it before, experimental only! |

Would that not be similar to the curves command in Photoshop ?
With curves you can move each light level to a different value, for example you can make shadows darker and highlights lighter to increase contrast. Instead of a straight line in the curve diagram you then make a slight S curve. (You can also go totally overboard and create the wildest collor effects).
Although it applies the curve to the total picture , it does affect the individual pixels each in its own way, depending on where they are on the curve.
Curves is a legal command, it is specifically stated. If this thing here is similar but just with a different name in different software, it would have to be legal as well. |

curves is different, curnes affects the image as a whole, like contrast, aturation, some levels get affected more, but not individual pixels, as the lighting filter does. |
