In the case of a photo canvas, the photo is printed on a canvas and pulled tight on wooden base frame. This canvas differs from painting one usually being smoother. The print on photo canvas is very detailed.
There are 2 types of photo canvases: satin and matte. Satin canvas glosses a little bit but is more resistant to physical injuries, touches, etc. You can also choose the thickness of base frame. The more common one is 2 cm, but you can also get 4 cm thick frame.
It is also possible to get premium photo canvas as satin and matte. Photo on it is even more vivid and detailed and the surface is very resistant.
