I have to do a 50 day timelapse of some construction work, the client wants the quality to be nice so I was going to use a couple of dslrs if I went with the Panasonic GH3 it has some kind of timelapse function built into it but I don't know how well it works. The problem is these cameras need to run almost 24/7 because the construction will be about 20 hours a day. The easy thing to do is use some Gopro HD cameras and mount them but from what I have seen video wise online the video will not look as nice as the dslr, the client wants the quality to be really good, what do you guys suggest? Thanks
