Lift Off

Emboss like effects.

Lift Off is a filter to apply emboss-like effects. The filter runs to more than just emboss effects (the reason for the variant name... it was called emboss but it does a little more than emboss and at times you might be wondering, this isn't emboss at all..). You can modify the direction of the emboss. It is limited to eight basic directions (left corner, etc), though it does have additional 'directions' that rely on the original image, so you can have an emboss on the emboss.. though the end results rarely look like much.

Please note that some of the controls have multiple purposes - the prime purpose is indicated. Also note that some of the controls will have no effect such as the X and Y if the (*) has not been set to on. Some of the options in the dropdowns use the X Y, or if no inverse option is set then the () will be ignored. Also note that the preview might not match the end result - especially if the setting is at less than 25% or so - to get a 99% accurate view of the end result please set the preview to 100%.

X - x coordinate. This is generally used by the spotlight (*). The spotlight applies the (*) factor to the current effect. By setting it to 0,0 the effect will be strongest in the top left corner - as you move the settings the spotlight will change position. Once the spotlight is past the edge of the picture the spotlight will just get brighter and brighter until it either obliterates the picture or completely darkens the picture (in most cases).
