That radiant glow

Until I used this photo in an illustration, I did not notice that the leaves glow. I swear that I did not do some special tricks in Photoshop to make that happen. I don’t know that much about Photoshop! And even if I did, I doubt I’d have the patience to draw glowing areas around each leaf.

The glow is just some natural lighting effect, God’s gift to this photographer.

Or maybe the sunflower is radioactive and I’ve received some as yet undiscovered supernatural powers from exposure to this thing?
