    Posted: 21 March 2013 at 22:03
I am glad DxO was quick to come out with Sony A99 support but perhaps they were a little too quick.
I have noticed a nasty green cast when pulling out the shadows. Here are three pictures...

1. Out of camera jpg.
2. Adobe ACR conversion with shadow at 100 to lighten shadows.
3. DxO conversion with Smart lighting at 100 to lighten shadows.

If you would like to compare the files yourself here is a link to the Raw file.








Cheers,

Yeah, I haven't seen it that bad but I have seen it. I thought it was from my LEDs but it may not be. They had the same issue way back in DxO 5 I think with the A700.

One of the things I don't like about my A99 is the greenish/yellow cast to areas of noisy shadow

As the camera is basically a sensor that converts light into data, you can hardly blame it for the way software renders an image from this data. If the cameras jpeg engine is the problem then perhaps you can, but then you're not using the full potential of the sensor anyway.

i have not seen it with the a99 and DxO 8.

what settings did you use exactly when making the conversion in DxO (white balance, tint, rendering (camera or general), any colormodifications?

i was not able to download the RAW file because i need a account to do so...

have you looked at the white balance? if you compare Lr and DxO they will show a different temperature when just opening the RAW file - in other words: if the colors are the same the figure in K will be different!

to me it seems primarily a question of the correct WB and the green/magenta tint.

Try this link for the files.

I used the default setting with smart lighting set to strong.

Note this is only in the shadows. You can not fix it by adjusting the settings.

I see the issue. Last time I had it with A700. I dropped them a mail, and also many other did. they fixed that in next release.

the file exhibits indeed a very nasty green cast in DxO, that cannot be removed with just another setting of the green/magenta tint slider.

i tried to get a better result with the HSL settings. it pays to play around with the various settings there for the different color channels:



it is more like Lr, with perhaps a little too much contrast and saturation.

i have seen different renderings for Lr and DxO, but usually DxO is just a little bit better. I have never seen such a color cast with DxO in the about 5000 images i so far processed from the a99.

I agree that DxO is usually just a little bit better then ACR. I have long used it with my A900 with great results.
It depends on the picture whether the green shows up but I see it over and over in any picture that needs the shadows pushed and there is also a general slight green bias. It's Very disappointing compared to how DxO renders A900 files.

I'm not that happy with ACR either. It doesn't have the problem with the nasty green shadows but it sometimes tends to have a slight magenta bias.

This is the problem with being an early adopter. The A900 went through a long period before it reached the results it gets now.

For comparison purposes, here is a Capture One 7 conversion. I did absolutely nothing to the pic other than convert from ARW to JPG.

Thanks Ruttt, Of course the real test is to lift the shadows and see if the wood is the right color or if it's green under there.
I would expect correct color as the problem isn't the file but how DxO is dealing with it.
I have to check very carefully and compare to ACR because it's so easy to get an unnatural green tinge. I do not have this problem with A900 files.

A new update to DxO came out today. I anxiously tried it but the problem is still there.
