Important please read -
My aim was to match the raw as closely in post to the H.264. The raw could have looked even better had I graded it more artistically (see DNGs on the blog) but the purpose of this test was simply to see how each perform in low light.
In the ISO 800 shot I could get approx. ISO 3200 exposure out of the shadows in the raw clip, which is why they are slightly noisier than in the ISO 800 H.264 shot. Huge dynamic range in raw.
The areas to watch out for are -
- Highlight roll off and latitude around lamp and candle
- Shadows and noise
- Crushed blacks
As you can see Magic Lantern's raw is not just cleaner than the already fantastic performing 5D Mark III was in low light, it is several fathoms above in terms of tonality, colour, highlight roll off, latitude and shadow detail. There's massively more data in the image.
This is a performance worth raving about. The ISO 6400 is easily as clean as the Canon C300, the current $15,000 low light king and ISO 12,800 exposures are perfectly doable! Yet with the power of raw you have full control over noise reduction in post, dynamic range, white balance and highlight / shadow retention unlike on the C300.
