Next to the D5 its the best performing ISO camera on the market. Not sure what your after as its the best technology available

I did consider the D5 but I have spent a lot on canon lens' so it did not make financial sense.

Until my computer sorts itself out I'll post a jpeg which has had the exif removed.
This was shot at iso 2000.

The grey of the wing looks particularly mottled. Is this the best I can expect?

The lens was a 100-400 mk2.

I mostly see jpeg compression artefacts when zooming in, so a crop of the wing, preferably hosted on an external site, would be a useful (bypasses the forum's resizing and recompression).


Camera, some lenses, too little time, too little talent

I don't have a hosting site.
How do I post a 100% crop from the original raw and include exif data?

Thanks in advance.

Also:

The picture has no commercial value so, I am prepared to mail the full raw to anyone who wants to help find out what the problem is (if any)

ISO 2000

This is the most noise reduction I can apply.
As can be seen, the details are already mushed.

I have sent you both a raw file.
I'm not sure if it's the exact same one but it is from the same shutter burst.

Thanks, fordmondeo. For whatever reason, this was a difficult photo to deal with. I don't have the answer for why that is, but here is what I looked at.

This is the full photo from the raw file as exported to 1200x800 by Lightroom:

IMAGE: http://www.lj3.com/1dx2/typhoon0.jpg

This is a 1200x800 crop. No adjustments made yet.

IMAGE: http://www.lj3.com/1dx2/typhoon1_noNR.jpg

This was processed in DPP. Luminance = 12, Chromiance = 6, Unsharp Mask Strength = 7, Fineness = 3, Threshold = 4. The details are definitely getting hammered.

IMAGE: http://www.lj3.com/1dx2/typhoon2_dpp.jpg

This is exported from Lightroom. Sharpening = 32, Mask = 50, Luminance = 74, Color = 18. It's better than DPP.

Here are my results.
For me it is not a matter of noise but a matter of dust.

Am I imagining the noise or not?
I can get useable results up to about iso 800, after that it's in the lap of the gods.

For sure, at iso 3200 on pictures of trees birds and bushes etc the noise is not noticeable. On flat colours it's iffy at best.

In my opinion, it is noise. I can't see it in the full images, but it's very visible in the 100% crops. I did notice that the photo was underexposed by nearly a full stop. In theory, that would make the noise a little worse, but I don't have any data to show whether that's the case or not.

I am headed to an airshow later today, so I'll see if I can duplicate the scenario.

Yes, I mean atmospheric dust. I am out of the discussion about noise in this kind of photo.
Have fun with that wonderful camera?

Thanks in advance.

In Lightroom you could crop to (e.g.) 1280x1024 pixels, then export as a JPEG with no resizing, choosing to keep all metadata.

Similar for Photoshop: but load the raw via ACR, crop, then save as JPEG. Off the top of my head I don't know what that does with the EXIF data.

Perhaps it's a camera setting.
I have to say, the rendering of flat areas of colour is falling short of expectations.

Should I reset everything and let the camera sort out the technical stuff?

Anyone got any suggestions as to settings for this type of photography as i am back at the mach loop in a few weeks?
AF mode?
ISO?
VR Mode?
Exposure compensation?
Auto noise reduction, yes/no?

Anything else?
