Ideal for photography

Tried lots of wordpress themes but they all seemed to display my photos very small – this theme actually allows me to specify the exact image width in pixels

Easy to set up, a ton of features in the customizer. Clean and fast.

Perfect and easy to use

I’m using WordPress for the first time and after trying lots of themes, this was the one I could costumize perfectly to my wishes. It was easy to use and I could quickly, and without much knowledge of it, create a child theme for it. Also the support ist really helpfull and fast, when it comes to questions.
I can really recommend this theme.
