In my point of view, it is smart and easy method to shoot window as a topic related to observation. I quite like Quentin’s this video not only he records both inside and outside reflections as a interesting frame, but also it present different perspectives from same device shooting, which is also relevant to my personal research that provide additional approach into the core.
There are two suggestions that Quentin could be consider. Firstly, if the point is focus on both side view, I think the sketch can be shot longer to capture contrast images via the window. Secondly, Quentin named this title as ‘coffee’, but as I mentioned above that the sketch is focus on the window or reflection instead of one specific object ‘coffee’, which readers could misunderstand the content of shooting from the title link.
