Hi Jeroen, I made several photographs with flash and without flash of what I think you mean, forgive me but google translator is not very good.
I think this is what you mean and painted, not stickers.
photos in different positions hope it serves.
I understand that it is difficult to do with a photograph, andalucia today is cloudy and there is plenty of natural light, and I hope that the photos are to your liking.
a big hug
