I do not know why they built in the camera of the smartphone the ability to take a photo with the effect of "negative", but I like this. I sometimes play - take pictures with the effect of "negative". Photos are fabulous. I do not have a field of application of such photos. Just indulging for the soul. Today I decided to post it here - negative and positive for comparison.
How beautiful flowers in the "negative." And let the green petals are not inherent in the flowers, I like to look at these photos.
In the original, of course, flowers are also beautiful.
