Original photo, no filter. I really like the photo here just because I take pride in taking original photos and adding zero effects. But if you look at this one it totally looks as though a filter has been applied.
It's something about the white rock based underneath the flowers you see combined with the glare of the shining sun. Gives off a hue of some sort almost like a filter if you will. I guess it really depends on how you look at it such as all things in life. A matter of perspective.
Don't let that take your focus from the beautiful flowers in the shot, a raspberry color really popping on a nice summer day a few months back.
