Discussing with strangers in the train this is often an opportunity for a new blog post. The main issue I have with new comers in photography (read people buying a camera), they usually focus on technical aspect and not on the act of photography. But sometime, I have interesting questions and especially this one: "Do you think there is a real difference between taking pictures or videos?"

This question was in my head for the past days... Photography is very different of a video. Photography is the ability to stop time at an instant. To create a new interpretation of an instant and build a new timeline in your surrounding environment. Some still photography is just so intemporal that you cannot even define when it was taken. I feel videography as ensuring a continum where you extend time where you don't keep control of the time like in still photography.

While searching in my archive, I found a series taken in the Virton train station. Every picture is a moment but it looks like a movie. The paradox if you add all the pictures all together, this is like a video which is not.Maybe the impression is linked on how you dream, it seems you have the impression of each steps, these steps are just a moment of our lives.

One year ago, the opportunity of doing an exhibition helps me to experiment something new with photography. In some past exhibition, I had the impression that some viewers cannot be immersed due to surrounding sounds (e.g. noisy environment or people talking too loud). The idea was to enrich my artwork with a soundscape supporting the viewers' feelings. The soundscape will be there to limit the overall noise disruption from the exhibition. The experiment looks fun to do and I try to document my journey to build a soundscape to support my photographs.

My theme for the exhibition was the train and I already selected a series of photos. Based on this photographic material, I draw some indicators that could be used as key elements or references for the viewers.

• Sounds of train starts (1)

• Sounds of train stops (2)

• Environmental sounds of train (e.g. doors(3), railways(4), people talking(5), ...)

• Vocal announces inside or outside (6)

Having these in mind, I recorded sounds during some trips in various trains or train stations in Belgium. I had the luck to borrow a Zoom H6 Six-Track Portable Recorder from a very kind colleague. Recording in public spaces is not so far from photography. The difficulty is the sound framing. Where you need to highlight a specific element in the sound and discard the rest. I was not used to record sounds, so it was pretty new to me. Similarities with the act of photography are interesting, being alone, avoid distracting elements in your frame or record the right instant.

After 3 months of recording raw materials (don't forget to limit level and record in raw WAV/PCM format), I did a selection of the sounds (another similarity with photography 'select or die'). I classify the samples to use in loops and the others which are longer samples. What's the process to create a coherent soundscape for the photo set. I wanted to recall the train atmosphere were you have some kind of monotonous sounds but which shouldn't be boring and tend to be forgot after a certain number of repetitions.

So I started with the loops, this is an art in itself. While listening to the raw materials, I selected some repetitive sound patterns. From the each of the selected repetitive pattern, I cut some seconds that could be repeated to reproduce the original sound patterns of the raw sample. The seconds selected should be clear without distracting noises. Then you can create the loops, tests it (keep the loop playing and listen) and save it (still in raw WAV/PCM format or FLAC). For this process, I used Audacity which is a simple but advanced free software to edit audio samples. The software includes functionality like finding the zero crossing point to have smooth transition in the loops.

After the creation of the audio loops (4 and 4bis), I had long samples with some specific element like doors closing(3), train starting(1) or stopping(2), vocal announces(6). How can I play all these samples sequentially and find an accurate pattern for my photo sets? I tried some audio software to do that but these are often huge and utterly complex to use (e.g. you need to use a graphical user interface to shuffle a list of sample for each experiment). I end up using bash and SoX to do the composition. This approach helps to focus on the content and just write some lines of shell script to create my soundscape.

The whole play script used for the soundscape written in Bash shell and using SoX:

#!/bin/bash

looprepeat="7"
fadeout="fade t 0 0 3"
LONGSLEEP=40
SHORTSLEEP=10
VSSLEEP=5

while [ true ]
do
        play BelgianTrainLoopOK2.flac repeat $looprepeat $fadeout; play BelgianTrainAnotherStopOK.flac $fadeout
        sleep $SHORTSLEEP
        play BelgianAnnounceBruxelles.flac $fadeout
        sleep $SHORTSLEEP
        play BelgianNewLTrainStart.flac $fadeout
        sleep $SHORTSLEEP
        play BelgianTrainLoop2.flac repeat $looprepeat $fadeout
        sleep $SHORTSLEEP
        play Arlon-to-Marbehan.flac $fadeout
        sleep $VSSLEEP
        play BelgianTrainDoorClosing.flac $fadeout
done

I also did a quick visualization of each samples to find out any glitches or issue that cannot be directly spot by listening. The above script runs during the exhibition and based on the mood of the day, you can change the parameters (time between samples) or the order of the samples.

Not sure if my first experiment is a success but I had interesting feedback during the exhibition. An old lady told me that remembers her when she took the train with her parents. Some where indeed more attentive to the photos or came back when they started to hear the soundscape. And another funny discussion was a guy working at the national train company in Belgium who remembered the exact model of the train.

The overall soundscape including samples and scripts are freely available under a BSD 2-Clause License.

While doing photography, I became slowly interested in the old and abandoned places. I released some of my pictures in a small urbex album on flickr. But my interest for such place is irregular and especially with some peaks. These wanderings into a kind of decrepit world could be in contradiction with my work on the movement, nature and people in the street. I strongly think that is the opposite where these dirty and old places are there to show the evolution of life. There are not still pictures, the picture of the abandoned places is the key to the new or the next step in our lives or environment.

The quote from the photographer, Sally Mann might reflect this:

"Photographs open doors into the past, but they also allow a look into the future." -- Sally Mann

Urban exploration is not an adequate term as the main focus is made on the journey into old and lost worlds. And the photography is relegated as an inventory step. I don't feel this as a tourist but more as a method to ensure that we are still alive. My peaks seem to be a kind of fearless interests in decayed world to take picture of an ending world but showing the future. Photography is an act of living.
