Understanding Sony’s SLog3. It isn’t really noisy.

Another interesting article by Alister Chapman about Sony’s new Slog3 gamma for the F55 and F5 cameras. Alister explains that even though the untouched footage may look  ‘noisier’ (unwanted ‘grain’ like structure) than the Slog2 setting, once both types of pictures are treated equally there is no more noise in one or the other, in fact there’s more details in the shadows with Slog3 in his opinion.

It’s been brought to my attention that there is a lot of concern about the apparent noise levels when using Sony’s new Slog3 gamma curve. The problem being that when you view the ungraded Slog3 it appears to have more noise in the shadows than Slog2. Many are concerned that this “extra” noise will end up making the final pictures nosier. The reality is that this is not the case, you won’t get any extra noise using Slog3 over Slog2 and Slog3 is generally easier to grade and work with in post production.

So what’s going on?

He does conclude that Slog3 does not give quite as much latitude in the highlights as Slog2 so it might not be the go-to choice in all situations.
