I had a lot of fun experimenting with the chemicals. I discovered that mixing a little of the potassium permanganate with the citric acid/sodium bi-carb mixture, it created a purple effervescent ball that looked amazing in macro. The footage I captured of that is definitely going to be in the final edit.
Also, the potassium permanganate had another usefulness. I was thinking of doing another time lapse of an ice cude and had the idea of sprinkling some of the crystals on top. As the ice melted, the potassium started to dissolve as well and as a result, purple started dripping down the sides. It looks almost like a melting candle. Another shot I got was of some kitchen roll absorbing the potassium solution and turning it a deep red/purple. It looks fantastic.
Reflection – I am extremely happy with the results of my experiment with these items, I managed to get some really stunning macro and time lapse footage that I know will work very well into my project.
Actions – Next I am going to be burning things, for example splintered wood, wire wool and also the malachite and iron filing that I have.
The editing process is coming along quite well, I have around two minutes completed with two and a half still left to go. It seems quite promising that I will be finished on target. As the deadline is now getting extremely close, it is my development folder that needs the attention now.
This is my finished time lapse with titles added. I used After Effects to create the titles, for the text colour I used the pipette tool to take the colour of a dark area of background in the time lapse shot. I did this because I feel the titles needed to be quite subtle, as one of the main ideas behind this project is opening your eyes to the usually overlooked. I felt that this resonated with the overall vision of the video.
Reflection – I am really happy with the final outcome of this time lapse. As it was my first attempt, I was not expecting such a good result. This experience has inspired me to use more time lapse photography in the video and I will be shooting more over the next week.
This is the end product of my first time lapse. I edited it in After Effects under the tuition of Peter Waiting, as I don’t have a lot of experience on the software. After a quick demonstration from Peter, he left me to experiment with colour tones and changes in scale.
The finished time lapse has had the saturation slightly increased to make it warmer and a gradual increase in scale as the time lapse progresses.
Reflection – I enjoyed getting to grips with After Effects as I do not have the software on my own Macbook which is where I mainly edit. I became quite familiar with the program and I now feel more at ease with experimenting within it.
Actions – I intend on having this time lapse as the title sequence for my finished video. I will add the titles, again, in After Effects.
So I have acquired some basic chemicals, nothing dangerous, to experiment with and film the results in macro and maybe time lapse. Below is a list of the things I have.
Potassium Permanganate – KMnO4, when added to water it breaks down and causes beautiful purple streaks.
Iron Fillings – Fe, when thrown into flames they cause sparks. Not sure if this will be easy to capture in macro.
Malachite – CuSO4, this turns the flame green when burned.
Magnesium – Mg, this burns a bright white when put to a flame. I don’t think that this will be practical to film, let alone in macro.
Citric Acid – C6H8O7, this stuff reacts to water in an effervescent way. When mixed with sodium bicarbonate and a little olive oil to bond, it creates a sort of bath bomb which will be interesting at a macro level.
Reflection – I am looking forward to experimenting with these items and I am hoping for some good results with filming them too.
Actions – I will film the experiments and post the results at a later date.
This site was extremely helpful with starting out in the field of time lapse. It gave me a lot of information that I wouldn’t have thought of myself.
Finally, the intervalometer that I ordered around two weeks ago has arrived. There were some issues with postage which hasn’t left me with a great deal of time to experiment.
I decided to start with time lapsing the melting of an ice cube, using macro, because after some research online I discovered that the main advice being given in photography forums was to start with something indoors so you can control the lighting conditions and the environment around the subject. After spending a while getting familiar with the intervalometer, I began to understand its functions and how to set the device up to shoot time lapses. Again, after some research online, I found that you can not just set the intervalometer to any random setting and watch it go. There are calculations that must be made to ensure what you are shooting will be captured with the right exposure, intervals between frames and how many frames need to be captured.
I figured out that an ice cube takes roughly 30 minutes to melt at room temperature. The rest of my footage is shot at 30fps, so if my time lapse is to run at 30fps that would make 10 seconds of full speed footage. To get 30fps for 10 seconds that would mean I need 300 frames shot, 300 frames over 30 minutes means 10 shots a minute. So I need to set the shot interval at 6 seconds to get the 10 shots within each minute. Below is couple of shots of the time lapse in progress.
Reflection – As this was my first attempt at time lapsing, I was slightly sceptical of how it was going to turn out. And until I have pieced it together in After Effects, I’m not positive it was a success. But I am happy with how the shoot went and I think that the knowledge I have gained about DSLR photography and filming over the past year proved extremely handy in the time lapse process.
Actions – Next I am going to piece together the photos in After Effects and I will hopefully have a decent time lapse that can be used in the final video.
