Sony A7RII versus Nikon D850 – noise

Posted on By

There’s a lot of noise about the Nikon D850 right now but few direct comparisons. One problem I have with some early reports is that new D850 owners are most likely to be existing D810 or perhaps D750 or D5 owners. Any comparisons are therefore being made with earlier Nikon sensors.

Recently a Nikon ambassador whom I respect greatly placed some .NEF raw files into a Dropbox for fellow professionals to examine. Since this article effectively criticises Nikon, I will not reproduce anything recognisable. I naturally grabbed the files and processed them with my usual care in Adobe Camera Raw. This includes making adjustments to the Sharpness and Noise Reduction settings depending on the ISO used. My standard with Sony, Nikon and most other files is to reduce the radius for sharpening to the minimum (0.5) leaving the basic settings of 25 for sharpness and 25 for detail untouched, with no masking. I also don’t touch the Colour Noise controls at all, and usually only adjust the first Luminance control leaving Luminance Contrast and Luminance Detail at default. This first Luminance control tends to set to zero for ISO 100 (or the minimum for a given camera), 10 to 15 around 400 to 800, 25 at 1000 to 2000, 30 to 35 at 2500 to 4000, 50 at 6400 and never above this level.

ACR 7.2 and Lightroom 4.2 RC – RX100 compatible

Posted on By

The good news is that you can now download, free, the Release Candidate versions (expire October 31st) of Adobe’s Lightroom 4.2 and Camera Raw 7.2, as well as DNG Converter 7.2, which will give you raw conversions for the Sony Cyber-shot DSC RX-100.

The bad news is that no camera lens profile is included, and until someone creates one, the distortions and CA of the RX-100 lens are not corrected by these programs. Also, we can confirm that no further highlight recovery is possible, beyond that already enabled in Sony Image Data Converter. This has not always been the case with ACR/LR. They have often enabled clipped highlights to be recovered with useful detail from KM and Sony raw files. The RX-100 raw files are right on the edge of overexposure and you just can’t pull burned out highlights back in.

But against this, the high ISO performance of the RX-100 is superior to, for example, the NEX-5n. That’s surprising and worrying, as the 5n is better than the NEX-7. ISO 3200 images from the RX-100, processed through ACR 7.2RC, are about as good as any APS-C camera currently manages and not far off what can be expected from a full framer.

Shot at f/1.8 on the RX-100, 1/30th, ISO 3200 – about as dark as it gets for hand held shots.

100% ACR 7.2 clip with NO noise reduction at all and no sharpening

On the Canon 5D MkIII, 1/3oth at f/2.8 using the 40mm pancake lens – twice as much light as the pub scene above, gold Olympic letterbox in Edinburgh seen by night time street lighting

Sure, at 100% under the same process conditions it is better – but once you apply NR to the Sony image, the difference is levelled considerably. And this is the world’s best full framer for low light, right now, over 20 megapixels.

Here is your download link for Adobe Lightroom ACR 4.2 RC:

And here is your link for ACR and DNG Converter:

http://labs.adobe.com/downloads/cameraraw7-2.html

The results at speeds from ISO 80 to 400 are a match for any DSLR, with the exception of the issue of dynamic range above highlight clipping. There is no significant margin for highlight recovery. This is a marked contrast to the early KM Sony sensor such as the 8 megapixel used in the Dimage A2, which had almost two stops of clipping-free highlight recovery using the metered exposure in high contrast situations.

Image Data Converter v4 – download now

Posted on By

Sony’s Image Data Converter latest version – 4.0 – will handle all Alpha raw files from A100 to A77, and all NEX raw files. It offers improvements in performance and stability, but it also eliminates the need for the Lightbox application (found in v3) as a separate item. You simply browse for a folder of images, and IDC now shows a regular thumbnail browser with image information not unlike Adobe Bridge.

Double-clicking the thumb opens the image as expected in the raw editor. This has all the features of v3 are a bit more, but at least on a latest MacBook Pro with 2GB memory it seemed to crash and quit (normally after processing the file) rather too often.

One new feature, found when you save the file and not in the main processing controls, is a crop with Inclination Control and a grid:

Testing Alpha 77 raw files on the new software, the Bayer conversion seemed to be incredibly noisy and the noise reduction left fine detail heavily smeared much the same as for in-camera JPEGs, but the colour styles, DRO settings and some other aspects read from camera EXIF data are retained. It can not be recommended as a main choice for raw conversion, and certainly not for high ISO images, but it’s available and is a fairly small application to install on laptops or less powerful machines.

DxO plug-in offers Alpha-NEX HDR/multishot simulation

Posted on By

DxO Labs today announced that a DxO HDR plug-in for DxO Optics Pro 6.5 will be released in November. The new DxO HDR plug-in will enable photographers to merge several RAW shots effortlessly to either capture a greater dynamic range in the scene or to reduce noise beyond the camera’s sensor capability.
DxO was already known to be working with Sony, and offers in-camera firmware programs. This Plug-In closely mimics the multishot HDR, Twilight or High ISO noise reducing modes of the NEX-3, NEX-5, Alpha 33 and Alpha 55. It may be related and perhaps we will see it one day as part of Sony’s raw conversion software suite.
High quality HDR to capture a greater dynamic range from multiple RAW shots
Even with high-end digital cameras, the sensor dynamic range limits make the capture of extremely contrasted scenes difficult for photographers who wish to keep both highlight details and opened shadows in their pictures. With the new DxO HDR plug-in for DxO Optics Pro, photographers can overcome this limitation by merging bracketed RAW images into a single image file capable of handling a wider dynamic range than a regular RAW image. Specially designed multi-shot HDR Presets will let photographers render this new image effortlessly with a broad range of intents from the most natural looking image to extreme creative styles.
DxO Optics Pro’s best of breed RAW conversion and optics correction, ensures optimal image quality. “The DxO HDR plug-in also provides automatic image alignment, needed to compensate for camera motion when shooting hand-held, and ghost removal, needed to account for moving objects within the scene.” said Cyrille de La Chesnais, Director Sales & Marketing for DxO Labs’ Photography business. “Photographers can even decide which instance of the moving object they want to keep in the final image.”
Noise reduction beyond sensor capability, from multiple RAW shots: in situations such as handheld telephoto or low light where low shutter speed is not an option, taking a burst of RAW images at the same exposure and merging them together with the DxO HDR plug-in proves to be an extremely powerful way to reduce noise beyond the sensor’s intrinsic capability.
“DxO Optics Pro’s best of breed noise removal applied on a merged photo, whose noise has already been significantly reduced by the virtue of merging photos, produces an image of outstanding quality,” said La Chesnais.
Availability and pricing
DxO HDR plug-in for DxO Optics Pro 6.5 for Windows and Mac is scheduled for release late November 2010 from DxO Labs’ e-store. Final pricing is not available.
System Requirements
2 GB RAM minimum
400 MB available disk space
To process RAW images larger than 20 MPixels, a 64-bit operating system with 4 GB RAM is strongly recommended
Windows :
Intel Pentium 4 processor or AMD equivalent (Pentium Dual Core or higher or equivalent recommended)
Microsoft Windows XP 32 or 64 bits, Windows Vista 32 or 64 bits, Windows 7 32 or 64 bits
Macintosh:
Intel-Mac
Mac OS X.5 or X.6

NEX, A33, A55 support – new ACR 6.2/LR3.2 final

Posted on By

The final release of Adobe Camera Raw 6.2, DNG Converter 6.2 and Lightroom 3.2 includes raw conversion support for the Alpha 33 and 55 models as well as the NEX-5 and NEX-3, Alpha 290 and 390 which were included in the Release Candidate versions. These August 30th releases are final version, RC versions are a form of beta test.
The bad news is that anyone using the LR3.2 RC as a temporary free solution for getting full profile correction without investing in Photoshop CS5 will lose their freebie. But Lightroom is eminently affordable, and it can function as a raw conversion front-end for any earlier Photoshop or Elements version. On its own, it is a mere 10MB of program data fatter than Adobe Camera Raw as a plug-in and runs with great efficiency on modestly specified laptops (etc). It’s a lean, keenly priced solution which offers many further benefits as a DAM (Digital Asset Management) library such as keywording, copyright control, metadata editing, version stacking and multiple catalogues.
http://www.adobe.com/support/downloads/new.jsp
I am informed that support is included for the 16mm lens on NEX (profile) but I can’t tell whether it is the profile I supplied to Adobe Labs, or a new one, because my profile has remained unchanged on my system – same names, same modification date. And there’s no NEX-3 version which might be expected if they had created new profiles. So it looks as if it could be worth sending profiles into Adobe after creating them.
It’s fantastic news that Adobe has released ACR for the new Alpha 55 16 megapixel sensor before the cameras even hits the street – mine is on order, waiting! Not so great for Nikon users; no D3100 raw conversion in this release. But Canon users get the 60D (despite Adobe missing it out from their front page list). Adobe did this Sony friendly pre-release once before, for the Alpha 100, getting the conversion into place before the camera went on sale.
The bad news is that the Alpha 580 and 560 models are not in the list alongside the fixed mirror pellucid, transflective (anything but Translucent, please…) cameras.
The instruction manual for the Alpha 33 and 55:
http://esupport.sony.com/US/perl/model-documents.pl?mdl=SLT-A33&region_id=1
is already on-line and shows a March 2010 publication date, which means that Sony has had these new cameras in existence since the beginning of the year, certainly well before PMA when mockups were shown. It’s likely that Adobe’s Thomas Knoll has been using one from the first bug-free pre-production model onwards!
Now all we need is the revised lens series with SAM or SSM motors fitted into the 16-80mm CZ, 16-105mm Sony, 18-200mm and 18-250mm Sony; the 11-18mm wideangle replacement, the 75-300mm SAL replacement, and a few other goodies. Hopefully all Zeiss glass gets SSM where possible. That 16-80mm CZ is four years old now as a design. A tweak to the maximum aperture, or the zoom range, would revive interest.

ACR 6.2 2010 Process – huge improvement

Posted on By

Before the launch of the NEX models, the last camera we reviewed here was the Alpha 550. The final review pages dealt with the high ISO performance.
Following the release of Adobe Camera Raw 6.1 and 6.2, the new ’2010 Process’ has replaced the ’2003 Process’ in conversions (you can select either option). The 2010 Process used with manual adjustment of the Noise Reduction controls can produce really exceptional ISO 6400 results.
This changes any previous conclusions about the usefulness of Alpha 550 high ISO settings, and indeed brings them into line with the results we have seen from NEX – which of course defaults to the 2010 process, and can not be processed using earlier Adobe Camera Raw versions.
Here is the old process, top, seen at a reduced scale of a 100% view at ISO 6400:

Click the Process 2003 image above to open the original 100% size screen shot.
Below is the new 2010 process, which is more than just a minor tweak – it’s an entirely different way of getting the data out of the raw file.

Click this image to see the Adobe Process 2010 result full size. All the settings were identical for these two conversions. The improvement is on such a level that ANY test reports on the Alpha 550 produced in 2009 using CS4 and Adobe Camera Raw 5.x are invalid.
The NR can be moderated to produce more detail on the 2010 process midtones at the expense of more visible grain (but it’s nothing like the 2003 pattern – it remains mainly a fine luminance pattern). I have used a setting which produced a clear comparison. Entirely different NR settings are actually better, with the two processes, but no matter how you adjust the ‘2003’ version it never looks anything like as fine as the 2010 one.
Should dPreview and others update their RAW sample images because the old process was so badly matched to the .ARW format? Nothing like the same difference is made for example to Nikon raw files, 2010 is better, but 2003 didn’t mess up the higher ISOs in the way it always did for Minolta/Sony raws.
Please note that if you don’t want to get CS5, you can still get the benefit of this new conversion with Adobe Photoshop Elements 8.

ACR 6.2 and LR 3.2 RC released – for NEX

Posted on By

Adobe has announced the Lightroom 3.2 and Camera Raw 6.2 Release Candidates, available for immediate download on Adobe Labs. The updates extend raw file support to 12 new popular camera models including the Sony NEX-3 and NEX-5, Alpha 290 and 390; improve on several of the lens correction profiles introduced as part of the Lightroom 3 and Camera Raw 6.1 releases; and add over 50 new lens profiles to help photographers automatically correct for undesirable distortion and aberration effects.
But they let Sony down in a big way by only including the 18-55mm OSS lens for NEX, omitting the 16mm which must be very simple to profile (after all folks, there are only TWO officially available lenses for NEX right now – you found time to profile no fewer than 15 lenses for the Pentax AF645, for the benefit of all two dozen worldwide users of this outstandingly popular digital option…)
