If you do not require a large glow, consider using the spot glow object instead. Unlike the rest of the objects, the glow object requires full-screen drawing and is therefore computationally expensive. Glows are generally placed first in the stack. If the lens flare is blowing out too much, it is encouraged to use screen mode. There is no right or wrong choice, rather what is more appropriate for the image.

Depending on the image and the lens flare, the artist should select the more visually compelling mode. Perhaps the most important controller in this section is the blending mode controller that defines whether to composite the final lens flare using additive mode or screen mode. These global parameters are meant to be used as final adjustments for compositing the lens flare on the image. For instance, the global scaling controller will scale all lens flare objects while the global flare center controllers will adjust the center-point of the lens flare that affects all objects. These parameters affect the entire lens flare as a whole and therefore they are not saved.

In addition to the object-specific parameters discussed above, Ultraflares also has global parameters. Most triggering values range from 200 to -200 but the scale triggering value ranges from 1000 to -1000. Each objectРІР‚в„ўs trigger value is located to the right of its controller value and the trigger mask can be displayed by clicking on the Display Trigger button. Triggering is an extremely powerful tool for creating ultra-realistic lens flares. For instance, an iris can scale up as it moves towards the screen edges, a glow can become brighter as it approaches screen center, or a streak can flare up when it leaves the screen altogether. Triggering opens up an infinite number of possibilities. A trigger mask is a gradient that defines how objects behave according to what position they are at. Adding a multi-iris object will unlock an additional set of controls that affect the sub-objects in the multi-iris object such as intensity, sizing, positioning, etc.Р”Р‡inally, each object also carries its own specific trigger mask. The multi-iris object is the most complex object Ultraflares has to offer. By combining various movement ranges together, lens flares can be designed to behave in very realistic ways. Some objects may be free to move in all axes, while others may be locked to horizontal or vertical axes. This describes how the object moves in relation to the lens flare light source. Additionally, each object may have its own set of transformation parameters. Each object can be meticulously adjusted using these parameters to reach the desired look intended. For instance, a glow object will have a gamma parameter (among many others) while an iris object will have a number of blades parameter (among many others).

When the lens flare is applied to the image, the stack is essentially flattened into one pane and placed over the image.Р”В®very object dropped into the stack holds its own unique set of parameters based on the type of object that it is. You can adjust the order of the panes by deleting, duplicating, renaming or disabling them. Each time a new object is added, a new pane is placed on top of the previous one, combining the images on the panes into a lens flare. It is helpful to visualize the stack as a number of transparent, glass panes.
