Step 1: The Elements
adjust the size depending on the type of application your working on.
The Flare will be composed of the following:
The Main Shiny Thing (MST)
The Other Shiny Things That Make The Flare Look Even Cooler (OSTTMTFLEC)
These Will Be Explained In Depth Later (TWBEIDL)
Step 2: Main Shiny Thing
The MST is a simple radial gradient.
Step 3: Other Shiny Things
Then duplicate the layer and smush again! (make sure you adjust the layer order so that the duplicated layer is on the bottom)
Duplicate twice more, then squish them even thinner, place them slightly over and under the middle, slightly offset.
continue with the duplicating, resizing, and repositioning untill you are satisfied.
Step 4: Making It Look Cool
Create a new layer and label it clouds.
Then apply the effect, guess what, CLOUDS!
You Have the CLOUDS! now,Apply a radial blur.
Step 5: Making the Actual Cool Part
then right click and feather it.
right click again and select Layer Via Cut
delete or hide the layer clouds
Step 6: Completing the Flare
If the definition of the light streak is too faint, then adjust the contrast and brightness
Step 7: Coloring the Flare
Create an Adjustment Layer called photo filter
(the reason were using a photo filter instead of anythin g else is so we can change the color of the whole flare and not have to tweak ech layer one by one)
Step 8: An Extra Tip
That way, you can select only one layer but move the entire flare.
Step 9: The End!
tip:save as a photoshop format to change the flare position and color later
EXPORT IN PNG WITH THE BLACK BACKGROUND
you can drop that on a photo or video and change the transfer mode to SCREEN or LUMA and you have a great lense flare! (only export without the black when you are not using the light streak element)
(Feel free to be creative and add more elements)
