[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]I have a Lumix DMC-LX5 that I bought from a LUG member. It?s ISO goes up to an apparently ridiculous ISO 128,000. The picture I recently published (Cat Bed) was shot as ISO 32,000. It was noisy as hell and I had to apply much LR noise reduction to it. On New Year?s Eve I took a bunch of shots in a dimly lit restaurant at 128,000. They showed absolutely no noise when viewed in LR at 1:1. When I discovered this, today, I took a set of test shots from ISO 8000 through 128000 at the same aperture. The shutter speed doubled at each step as it is supposed to. Again, when I examined the shots, the noise peaked sharply at ISO 32000 an fell off at either side of it. I?m delighted to be able to shoot at 128000, but I ask: ?What the hell is going on?)
