Low Key Lighting

Why Practise Low Key Lighting?

We decided to practise some low key lighting as we had not really had much experience or previous practise with studio lighting; also we were able to observe and correct OH&S issues in our own studio. 

Brief: To practise low key lighting and demonstrate that we are able to identify and handle OH&S issues on set. 

·      Equipment Used

·      Canon 500D

·      Tripod

·      Small barn doored studio light 

·      Back Drop 

·      Extension cord

·      Experience

            When filming low key lighting I found it very fun. I was comfortable in my environment, as everybody there were aware and knew what we were doing (because they were all participating as well). I also enjoy the footage that we ended up with and how we were able to experiment with the miss en scene more freely than we were able to do when on location. even though this does not completely fit in with new wave techniques, -such as natural lighting, real location and people used and innovative camera movements, to name a few- we did you innovate equipment and cheaply constructed equipment that we didn't have but needed, like a darker back drop made from large pieces of card being taped together; also by compiling all of this footage we were able to practice editing technique, like the Kuleshov effect.

Lighting

When we were filming the footage of Sammie and Will at the table the small studio light was to bright and lit the scene to much, not only defeating the object of lows key lighting but also the white back drop could be seen and this also took away from the effect. To deal with this problem we used a phone light to reduce the amount of light present and we placed it on the table behind the bowl in the subjects face, this help to light the subject only and not the surroundings like was happening before.

Back Drop

 To begin with we had a plastic back drop that was meant to be used for filming and photography like we were practising  however this back drop was to heavy for the stand and kept falling off the roll and causing the stand to become unstable. we fixed this by use a lighter white sheet that we found in the studio. this stayed up fine and did a good job as a back drop, but the sheet was creased and made some shots look unprofessional. when we wanted a white back drop we increased the aperture so that the background was not in focus and the creases were not seen in the shots. 

      Even though the white sheet worked as a back drop, in some shots it caused the scene to be too bright and the low key lighting effect was not accomplished. we tested different ISO settings to see if altering the amount go light entering the camera would make any difference, but this didn't work. So to concur this problem we taped together some black card that we found also in the studio and held them behind the subject when we were filming. this helped to darken the surrounding and helped improve and emphasis the low key lighting effect that we were trying to accomplish. 

 In this clip you can see how the black back drop causes the table cloth and bowl colouring to pop more and stand out. 

  OH&S on set 

       There where a few health and safety problems that arose but we were able to quickly and safety adjust and remove these problems to make the environment safe for the crew.

       The first OH&S was the back drop falling. this was dangerous not only as it was heavy and could fall on to the subject we were filming sat in front of the back drop but also because it caused the stands that were hold the back drop up to be very unstable and liable to fall also. we mended this problem by removing the heavy back drop from the studio and replacing it with a lighter back drop, that didn't fall of the stands or cause hem to become unbalanced in anyway. 

       The second problem was the cable from the extension cord not being secured down. We taped the cable down to the floor and around the chair leg that the cord was on. By doing this any excess cable, that could be tripped over, was removed from the equation in turn removing any dangers from the set, reducing any  harm that to a crew member may come across.

      Finally heat from the studio light was a problem. Most studio lights get very hot when left on for any period time, as we only used a small studio light the amount of heat produce was less than that of a larger studio light, but still needed to be taken into the OH&S account. We made sure that all crew members were aware of the heat from the light and when the light was not in use any more it was switch off and left to cool before packing it away;  this not only decreases the risk of injury and burns to the crew but also prevents and chance of a fire if the light were to be packed away into its bag before completely cooled.
