All it took for Matheka was a visit atop Nairobis landmark, the Kenyatta International Conference Centre, where he saw a different side of Nairobi that he wanted to capture for himself.
I was still an amateur photographer then. I wasnt on social media and did not even have a blog. I just took the pictures for myself, but later when I uploaded them, they went viral.
People have never seen the city looking like that, and they were pleasantly surprised, he says.
He agrees that the city needs to do a lot more to improve its image.
I did not take the pictures to change the perception of foreigners but for us as Kenyans. Everybody was pleasantly surprised. Online, the comments on the pictures range from they are photoshopped to that is not Nairobi, says Matheka.
Matheka, who started taking pictures just four years ago, has a philosophical look at his work. They offer hope and hope derives more strength than despair.
The pictures have proved a hit with foreigners, who are shocked when they see a different Nairobi from what they have heard or seen in the pictures.
They look at this city, which is in a third world country. You look at Paris, New York and Dubai and you just want to visit them, but when you get there, of course they are nowhere close to the pictures you saw.
