         Naast foto’s die bij bepaalde activiteiten horen, kom ik vaak situaties tegen die ik de moeite waard vind om op beeld vast te leggen. Wist je dat ik de meeste foto's op dit blog met de camera op mijn HTC One S of OnePlus One maak? Geloof het of niet, maar zelfs sommige van de prachtige panorama's boven elke pagina zijn daarvan afkomstig. Natuurlijk vul ik mijn eigen foto's aan met exemplaren van anderen.
