Rolling shutters and CMOS sensors

A warm welcome to all. Here we talk about films, which people put onto YouTube or Vimeo and embed here. The idea is to allow useful, friendly discussion.

Rolling shutters and CMOS sensors

Post by tom hardwick »

I've often talked about the pros and cons of CMOS sensors that have now almost completely taken over from their CCD fathers. There's a good page here that explains some of differences:

Thanks Tom. Good article.

All we need to do is ensure that we shoot static subjects with locked down cameras under perfectly consistant lighting, ten.

Perhaps it's just as well everyone is ditching camcorders for for 5Ds and 7Ds as when we all realise we can't shoot moving stuff anymore at least we'll have decent stills cameras. :D

Good point Tim. When I shoot movies of static subjects with my static 60D it can look pretty good, but if the trees move or my camera twitches slightly the fine detail in the image sets up horrible moiré patterns. Nothing to do with the CMOS chip in the Canon, more to do with the camera's down-conversion.
