Seems effective.

Amazing setting/light levels
A great way to be able to make ISO 25600 usable

Great results.

The AI Noise Reduction is also introduced in Camera Raw now.

Very impressive.

This eliminates the temptation of DXO Pure Raw 3.

Another example with people (apparently more challenging); noise reduction at 50%; ISO 12’800

without

with IA NR

First quick conclusion: the NR IA generated pictures do not show the “cheesy” look compared to traditional NR treatment.

It is AI  and not IA.

An example with high ISO of 4000 with the D700 and two stops underexposed, so pretty dark.  Brightened in ACR.

Before - After

Looks satisfactory ? No ? And what is IA and what is not, might be a lengthy debate, I prefer to forego.  :)

To my eyes it looks just as unnatural as those others Extreme Noise Reduction software ;)  But I need to study in detail, this is just the first impression.

IA is the French version of AI? Like OTAN/NATO?

Yes: Intelligence Artificielle (IA). And speaking every day French (although not my mother tongue), I have a tendency to mix them up.

Looks like the AI is doing an admirable job.  The texture of the man's cap is very well preserved.

Again, the details seem to be well preserved.  I wonder if the AI interpreted the horizontal streaks as the characteristic of anamorphic lenses?

In my opinion (it's free so it's worthless) the racing photo looks better without noise reduction.  The noise/grain gives it a more realistic quality.  For the people photo, it's a toss-up.  I would probably go with the reduced noise photo but they seem close enough for the noise to not really matter for me.  The IA definitely helps the last photo and, if this type of scene was something I often encountered, I would be tempted to use this software.

Thanks for posting this.

D700 famous for its banding at higher iso.

When to apply noise reduction and at what extreme surely depends!

Thx. I consider this as an additional tool. But normally, I can live with noise. Maybe I will use this a couple of times. Opposite to the whole new masking tool set, which I’m using every day. Speeding enormously the process; essential for me as a sport photographer :)
