Summer research continued.

So as well as looking into the Red one, I also decided to look at DSLR cameras that were also becoming a popular choice for some short films. The camera that took my eye and had heard most about was the Canon 7D, which unbeknown to me, we can use this year (if it is ever available!).
The Canon 7D only shoots 12 minutes of film footage in one take due to European law stating that 12 minutes is the boundary between being a stills camera and a video camera apparently. So with that cleared up, the 7D houses an 18MP APS-C CMOS sensor and shoots full HD. It writes onto an SD card, (in case anyone is using the 7D get a good quality card, it’s been said that a cheap SD card may drop frames)

Anyway after a bit of research and watching the making of some short films shot with the 7D, there are a few downfalls to it, without going into too much depth, one of the main downfalls people have mentioned is that, sometimes the camera picks up what is called moiré, an artefact of an image which is highly unattractive. It is an aliasing problem, where a pattern (of lines parallel to more lines) can appear on the screen making an image appear with green and purple lines over it. This is common with walls, bricks, mesh on fences and that sort of stuff.

Here is a basic video of the 7D with moiré, overexposed so it is more visible

Below, however is a video of another Canon 7D with moiré (on the roof), but this time, stephen v2 seems to have a theory, where the moiré disappears when the camera tilts. So possibly if you really didn’t want any moiré, you could canter your shots to a level where the moiré isn’t visible and then re-orientate your shots in post. So there is a few things to think about if I want to use the 7D for my project.

So overall, the 7D is an amazing camera, and can shoot some great vibrant images but you have to be able to use it correctly, because mistakes with it are going to be clearly visible.
