I went to Photo London and had the chance to hear the conversation between these 2 artists:
Adam Fuss is a camera less photographer and Antony Gormley a sculptor and are interested in each other works.

The artists raised a few points that I found very interesting:

Does the artist need to represent everything or should it be guessed? the art work is a catalyst for the viewer to float, the artist must bring a deep and not superficial connection to the art piece. Adam Fuss prefers to reduce the apparatus , and works without a lens.
Do we want to know how it is done technically? It is sometimes because people don ‘t understand what the image is all about that they start focusing on the technicalities of how it has been produced.
Process: an accident happens in the darkroom, the artist recognizes it as a revolution , for example the pinhole camera was dusty so the light came at a funny angle. That leads to experimenting.

The artist must create the environment, the context, tools and maybe he can discover something.

we need art as a place we can free ourselves from determiners of the material, beauty is compelling, and in wonder we can engage.
Antony Gormley insists his statues are not portraits, but a place where a human body was, not him. He just put the statues in high places as more effective there.
He would like to make the viewer more aware of themselves and the environment.

Adam Fuss said he is controlling about what is right or not, in his best pictures, he found a clue by accident and followed it. He needs a reason to keep looking at an image. If the image is not compelling and just pretty for 2 seconds, it is not satisfying
