It's not unsual, when taking photos that include the sun, where the sun is partially obstructed by tree leaves, the edge of a building, or other such things, that the resulting image shows sharp spikes shooting out from the perimiter of the sun. I'm trying to learn how to create those in photoshop when they don't show up in photos where I want them to show. I'm using CS6. I've learned how to do Sun rays, but these are different.
are these "spikes" you may be referring to:
Last time I did something like that, I found a similar photo, stole all the rays with a mix of manual and magic wand selection, 100% desaturated it to black and white, eliminated everything darker than about 90% to get only the light parts with the levels (output) tool. Then I duplicated it and selected the beams only then erased them and replaced them with a light yellow to match sunlight then set it on a screen layer mix. You can also use colorize in the hue/saturation tool to make the layer itself yellow. Then I merged them and pasted it on top of the other photo and set it to a hard light mix. You can even select individual beams and rotate them to fit better in the target photo
I attempted to draw them from scratch initially but it just looked far too fake and even. I would have had to do some weird gradient thing which wouldn't work too well because of the beams widening.
Normally I am against spam and don't promote my products here, but I have been informed by Adobe that if my own products can answer a question directly, there's no real restriction to posting info on them.
There are certainly ways to do this manually with the application of elbow grease, and possibly even other products available, but creating such effects easily in Photoshop can be accomplished through my commercial plug-in product called StarFilter Pro 2. I painted a round sun against a background similar to the one you've shown above then applied my plug-in several times so as to get the doubled spikes and extra color. This was the result, and can give you an idea of what's possible.
Great! As a tip: For the finest level of control, render the effects on a separate layer with a blending mode of something like Screen or Linear Dodge (Add), then you can manipulate that layer separately and mold the effects into exactly the look you want.
