Memories - Short Film

Though this isn't a typical romantic genre of film, it was a video suggested to me which I watched. I liked some of the techniques from this , such as the fast-paced fading between frames to represent time going by and especially the still pictures coming to life in the film reel and photo album.
There is no description of the narrative behind this short film, but personally I believe that the central protagonist is remembering memories when he walks around the city he is in (hence the film reel to play the memories) but when he reaches his home he forgets the memory. I wondered if the message behind this was related to dementia and raising awareness for the disease.
The film follows an Active audience theory because each member of the audience will decipher this film in a different manner.
This film follows a multi-strand structure as the male protagonist has flashbacks or memories when he picks up the camera reel. It can be considered to have an open narrative at the end because there are no answers for the flashbacks or what has happened since then. Also, the ending is a fade to black so the audience ask what has happened to the male protagonist, has he died? has he fainted? has he lost his memories?

Sound / Music:
A single track is played throughout the film which is mainly piano to create a soothing and easy-going mood to the film. When the film reel is blowing in the breeze however, that sound is dubbed in so that the audience are aware of what has attracted the male's attention.

Cinematography:
Establishing Shot, Close-Up, Long Shot, Pan (sideways and up&down), Handheld, Upward Tilt, Profile, Zoom, Extreme Close-Up, Medium Shot, Point Of View Shot, Over The Shoulder Shot, Stationary.

Editing:
Fade, fade to white, fade to black / transition of eye closing, cut, fade in.
Overlap of clips, showing passing of time and how many film reels he's found.
The colour seems faded / quite grey and dreary looking for reality. The memories have a fuzzy edge around them to show they're memories and have a sepia tint to them to suggest they're old. Also have an old film effect with lines crossing the picture.
Shallow Depth Of Field - when the man is walking towards the film reel, we see what he is walking to / has his eye on.
His home doesn't have a colour tint, this possibly represents that he is at home and feels welcome there and belongs there, unlike in the city.

Mise-En-Scene:
City is represented as dreary and deprived. Busy city. Grafitti, yobs (male with jacket up in the background), busy working people (woman walks by in office attire on mobile phone), lots of traffic. Set in an English city because of the pedestrian crossing. Establishes it's English.
Home - has a cosy fireplace, representing English again? Solid dining table, net place-mat on table - suggesting the male has traditional values?
