Production: Experimental Footage to Project
Today we were able to successfully film experimental footage in order to project over the devil and angel characters in the studio. We did this because we were interested in capturing more projection footage in order to cut away from our narrative and establish the intentions and persona's of the two characters within our narrative successfully, aesthetically and easily. Rather than use existing footage, we were interested in capturing our own as we felt it would give us a greater amount of control over the aesthetics and because we were unable to capture more footage of the warehouse during the day. Before we began, we collected the Canon 1100D and Manfrotto tripod that we had arranged to use. As a trial, before setting up to film chemicals such as potassium permanganate  and inks such as paper dye, we noticed a lava lamp and asked if we would be able to film it. We chose to do this for two reasons; firstly, we wanted to practise setting up the camera and familiarize ourselves with filming small subjects behind reflective surfaces, as we were moderately concerns about how successfully we could film ink because of the fact that the glass tank would be reflecting light, and secondly, because we liked the colours of the lava lamp and felt that the movement of it could be used to project, allowing us to capture interesting, unique and aesthetics projection footage.
We stood the lava lamp on a desk in front of a perfectly white wall, and set the camera and trip up so that the camera was at the correct height for the subject. The camera was relatively close to the lava lamp, but we had the lens zoomed in so that none of the room is visible in shot. We focused the camera, before realizing that the reflections on the glass were incredibly noticeable. Below if a gif I made to illustrate the prevalence of the reflections in the first piece of footage that we captured of the lava lamp. This piece of footage was shot with the correct exposure settings, meaning that is captures the lava lamp as it was, pink, with a white background, however, this meant that the correct amount of light was allowed into the sensor, meaning that the reflections were also captured. This is particularly noticeable in place where the lava lamp fluid is in the shot, as the reflections blend into the white background in the negative space.
In order to counter this, we firstly tried holding a black coat around the set-up that we had, with the intentions of blocking out reflected light. This worked in part, but then we tried completely underexposing the shot, which changed the pinks to red and the white background to a very dark brown colour, as seen above. We felt as though the red was much more appropriate for the sequence, as red has connotations of danger, and thus filmed the above clip.

We liked the footage of the lava lamp when filmed with the camera set-up to underexpose the subject as it, coupled with the holding up of a black coat, meant we were able to remove the majority of reflections. However, though the red fluid was more appropriate to propject than pink, we did not like the brown colour the background had become. Thus we opened the clip into preimere pro and used the ‘RGB curves’ and ‘contrast’ effects to correct the colour in the background to black, as seen below, which we feel is overall much more aesthetic. We will be projecting this clip.

After filming the footage of the lava lamp, we felt confident that we could film the footage we had planned to. We found a technician named Ken who retrieved for us the tank we had agreed to use and the chemical that he had said may work well. At this point, we could not find the portable studio and thus we set up in a similar manor to previously, with the tank filled with water with a white piece of card behind it and the camera, on a tripod, set-up so that only the tank was in frame. We had to set up in the colleges darkroom, with the lights on, because it was the most convenient free room we could use that had a tap in it, to re-fill the thank with.Â

Above is an example of the footage we filmed with this set-up. Reviewing the footage now, it is clear that this shot is not particularly successful and thus cannot be used in a sequence that will later be projected over our characters.While filming, it was not clear that, once again, as the tank filled up with chemicals and the water was thus darkened, the reflections were prevalent. We had filmed this with the subject underexposed by 1 stop and with the black coat held up around the set-up.as a precaution, but clearly that did not prevent the camera from capturing reflections. While the reflections are not as bad or noticeable as they could have been, there are other aspects of this footage that make it, to me, unsuccessful; there are water droplets on the tank, in clear focus, and thus the camera is not focussed on the chemical. This detracts from the aesthetic of the potassium permanganate. The colour of the background works to the same affect and overall gives the shot an unprofessional and un-aesthetic tone. The movement of the potassium permanganate is perfect for creating the footage we envision, but the chemicals tested prior were thin, lacking in pigment and overall did not move in the water in the appropriate, slow manor. We will not be using this example in the sequence for projection.
We then moved up to the colleges art department, were we found the portable studio and collected the paper dyes in order to film the majority of the footage we were able to capture on the day. At this point, Julia and I had massive concerns about the trouble we were having with reflections on the glass. Thus, we took a moment, while setting up, to look up ways in which we could minimize the number of reflections visible. We found this video:
Above: Shooting Without Reflections
The tips the the video offered us included holding up a black coat, shooting face-on, shooting without flash, and shot without the sun on the glass, of of which we were doing. Thus we decided to set up in the back of the room, so that the lights were in-front of us and were consequentially blocked by the back wall of the portable studio. Secondly, we cleaned the tank thoroughly. Thirdly, we tried pushing the lens up against the glass. Unfortunately, because of the small size of the tank, this meant that the camera would not be able to focus on the subject. We tested this by putting a pen into the tank, with the lens against the glass, and attempting to focus on manual focus. Because of the focal length of the lens, this was impossible. When we tried to rotate the tank so that the camera was looking down the longer end, we found that we were unable to zoom in enough to block out the side walls of the tank, meaning that in the background there was vertical lines, detracting from the shot. Thus we travelled to the photography department to try and find a macro lens or macro filter (to help with focusing on close objects) or polarizing filter (to reduce reflections.) Unfortunately, we found neither and thus went back to the media department were we collected the Lumix G1, as a teacher recommended we try and different camera. We set this camera up as we had done with the 1100D and decided to begin filming. We were able to push this camera closer to the glass than the 1100D, so we chose to attempt it once and then decide which camera we felt was more suitable.

Overall we found the Lumix G1 challenging to use and thus switched back to the 1100D. We felt we had wasted a lot of time with setting up, but were finally abe to film, dropping paper dye (a powerfully pigmented powder) into clean water using a small paint-brush. Below is an example of one of the pieces of footage we were able to capture. This particular example is successful, though the the bottom of the tank fills with darker pigment the reflections begin to show. Other than this, the colours and movement of the dye is successful, aesthetic and is perfect to use as a piece of footage to project. We liked the organic appearance of the shapes the dye formed into and the slow, hypnotic movements it made in the water.
Overall, filming with darker pigments meant capturing greater, much more vivid reflections. Within this example we were able to crop the footage so that we removed the bottom of the frame, where the camera was beginning to become visible. As an experiment we also reversed the speed of this example, in order to see how the movement created interest. This is clear in the gif below.
Above: Reversed, Cropped Example
There are some examples of footage that were so dark that the room we filmed in is visible in the glass. These pieces of footage cannot be used. However, in some examples only small reflections can be seen. We hope to use these example as footage to project over the character of the devil, who wears black, because the projected footage will not show up over her clothes. This means that we can save some footage. Overall we feel this was a successful use of our time; we had to solve problems throughout the day, but feel we were able to capture enough footage. We have begun and will complete a sequence of the the experimental footage that we can later project onto our main characters.
