You haven't been in Istanbul yet if you never spent time in Taksim, the center of businesses in Turkey.
That place is the busiest area of Turkey. I am not doubt to tell you that you will always missing it when you didn't go there for long time. But be careful, Taksim is also known as one of the scary places of the world. You can be spammed there if you didn't watch your self.

Actually at the time I was waiting for a concert of a music band in Konya city, Turkey. As a private photographer of them I had to ready for their moments. Along they were doing the sound check on the stage, I walked around at the yard and fell 'click' with the yellow flower when it met my shoes. Then here they were. :)

Was just walking around enjoying the nature at a residency.

Was getting bored to wait for a flight at the Soeta airport. #AcerLiquidJade

Just my casual style.
