NX70 low light test

One last video from me for this weekend:


It was a nice warm, clear night last night, so I decided to try some shooting in low light. It was an hour after sunset, and the sky was just about still bright. I switch on the lights later in the video, adding a 100W reflector bulb to the mix, with another 100W bulb round the corner also contributing.

The h264 encoding has gone a bit blocky on the darker areas; download the MP4 from Vimeo to get a 1920x1080 version.

Being realistic. this is pretty good performance from a single chip CMOS camera in very dark conditions. I wouldn't dream of shooting in this kind of low light normally, and certainly not without some proper lighting being added.

It's not a VX2100 or a DSLR, but it's not terrible!

Again not the best lowlight camera but it can hold it's own. Nice test.

Re: NX70 low light test

Not bad at all. Thanks for taking the time to put this together.

I couldn't quite tell whether the Low Lux mode introduced additional grain (i.e. whether it boosted the gain or not). Is that what Low Lux mode does, boost the gain?

Re: NX70 low light test

It looks to me like a gain boost (above the 21dB available in camera). It does make the picture a bit more grainy - the compression makes it worse.

I deliberately posted footage without any processing (Neatvideo noise removal etc.). I'm sure with a little bit of processing it could be made to look better.

I'm pleased with the performance; this camera is without doubt not a lowlight king, but it does give acceptable results that you could use as a last resort.

Re: NX70 low light test

I think the Low Lux mode on the small Sony's drops shutter speed ( it accumulates ) and boost colour. If you pan around you will see that you get motion trails a little too. I use a lot when on holiday etc to always get a reasonable shot. Not competition for an EX1 but better than my NX5U or my FX1 can manage.
