ISO




Due to the fact that I wasn't able to alter the CANON EOS 1100D's ISO or shutter speed, the picture was grainy and the lightness of the image changed immediately after it drifted into different light level of the room (pardon the mess, by the way). Therefore, my media teacher recommended that I use the CANON DSLR EOS 600D (which also had a flippable screen which was more practical for shooting). With it, I decided to tamper witht he ISO and found that less noise and grained was visible in the footage if compared with the former. However, a lot of the light was lost.




Here is me toggling through different ISO settings. The shutter speed is kept on 30 so that more light can enter the lens, as it's exposed to the scene for a longer time. If the shutter speed was higher, there would be flickering lights in the video where the lighting is pulsing as the shutter speed tries to quickly take it in.


If I choose to use a low ISO for my filming, I will have to make sure that my set is well lit. This may be an issues if I wish to film in The Pit due to the darkness of the building. If I did, it would be wise to consider investing in floodlights and borrowing the LED rotolights from school.
