DP2 - Still green cast - worse than DP1?

Just for the record, IMO my DP1 does not create a green cast under
any shooting conditions. No problems with IQ whatsoever. It's so good
it's spoiled me for other cameras :)

Just for the record, IMHO my DP1 will look magenta moreoften than green if/when it's off in color tones. The sunlight wb makes mine distinctly more yellow (which could be termed green). Interesting that I shot the park series in a new custom white balance set on the camera and the whole series someone would say is more 'yellow-green' than similar Pentax photos on auto. But the greens.... really are new spring green after much rain yellow-green! The DP1 is being accurate on custom white balance. I set up the Pentax on sunlight white balance yesterday, the greens are much more yellow-green rather than emerald green. Emerald green is nice and looks pretty, but emerald green (rich blue green) is not 'true' color this time of year in Virignia. photos on http://www.flickr.com/photos/sandyfleischmann

Its obvious that since the white license plate has a green cast that
white balance is off.

I think the comparison between the two cameras is really more significant than whether either cameras get the license 'pure white' which might be hard to do with variable light with any camera. The right hand car DP1 Hyundai license actually seems greener on my Dell screen than the DP2 license. And look at that reflection on the left hand car in the lower photo! That light source is surely doing something to the color.

BTW, moreso than color, the biggest thing I notice about many of the DP2 photos on http://www.flickr.com is that most new users don't seem to have their metering and/or exposures well under control yet (new camera).

It's not the same picture it was. A new version has been uploaded where the DP2 version is now redder than the DP1 version.

I agree. The image has a completely different color balance than it did earlier. That is why there has been disagreement on the color. Originally, the color on the dp-2 versions looked really bad and much greener.

It appears it's more a case of Sigma not having their metering/exposure/AWB under control yet in their cameras. I owned the DP1 and now own a DL4 and the Leica can produce images out-of-camera that are accurate across the board with minimal PP. The DP1 and DP2, on the other hand, seem to require inordinately high levels of PP. This won't stop me from buying a DP2 but it would be great if Sigma could get the basics right.

well, I find that which metering mode makes a big difference. Take a person in front of a big window or big sky and if you're on matrix metering, the person will be underexposed ;-)

I'm still psyching out the best uses of which modes when.. on all my brand cameras. A lot of the new users I bet are just firing away on matrix mode..

My DL4 is set to matrix almost always and has no problem nailing exposure in a range of lighting conditions. There's also no justification for lousy AWB just because the camera is set to matrix metering. Exposure and AWB is really basic stuff in a P&S. If my iPhone can nail exposure/AWB then surely Sigma can do a lot better.

Huh? white balance and metering aren't the same thing, ie matrix metering doesn't cause 'white balance' problems but it can cause exposure problems.

Great, hope you enjoy your iPhone, seriously.

But I like to print 11x14 usually for walls; plus I've seen A0 prints from my Sigma cameras' photos.

My DP1 needs 10C+5M correction on every shot. It definitely has some

Wow, you processed every DP1 shot with the same colorwheel numbers in your Sigma DP1 gallery?

... I wish I could find one set of numbers (!)

... what white balance do you shoot, or if various, how do you select your white balance or do you do custom white balances?

If I set a custom white balance on camera, the 0 position on the colorwheel is pretty accurate.

Sandy,

I made an earlier comment the Sigma don't have a handle on exposure and AWB and you responded that new users just fire away with their DP's set to matrix. I agree, metering should not affect AWB.

And if the cheapest point and shoots can nail exposure and AWB with a high strike rate surely Sigma can do better with a top end unit like the DP1/DP2.

I also own an M8 and images captured with my DP1 are amongst the very best. But Sigma seem to make a mountain out of mole-hill when it comes to the basics like reliable AF, exposure and AWB. It's not my intention to disparage the DP's and I am not an endorsee for Leica, I'm just calling a spade a spade.

Sandy, that's a recent discovery; those were taken and processed before I figured this out. But most of them have some sort of correction. I went back and looked at a few of those, and applied that correction to the original X3F, I think improves some of them. They were all taken with Sunlight.

That correction applies to Sunlight WB, and photos taken under Sunlight. And it does need fine tuning sometimes, but I find it a good starting point - much more neutral than 0. And I know this because I've been shooting a gray card.

I took a picture the other day, under overcast conditions, and WB set for overcast. 10C+5M was a good starting point too, also for Fluorescent .

I tried a custom WB. The correction is not needed. 0 is correct.
 
FWIW, I just posted my DP1 dogwood photo links in the weekend thread http://forums.dpreview.com/forums/read.asp?forum=1027&message=31704400 shot the same scene with auto white balance, sunlight white balance, and custom white balance set at the scene. I put up the X3F versions, ie 0colorwheel no edits for all three, and then also edited sliders for the cwb version. Colorwheel 0, really only needed very minor edit of sliders.
Best regards, Sandy

.... or you guys also see that both pictures were shot from different locations?

It looks like Rick has shot'em from two tripods. One for DP1 and one for DP2.

Just check how Jeep is being parked on both pictures.

If he really has used two tripods, pictures shot from different angel can look different.

And this is, I think, what is happening here.

But magenta cast can be there anyway...

Just my 2 cents.

....or perhaps this is different focal lenghts of DP2?

I'm not sure....
 
Look at the space between the two cars. Using the DP2 shot as reference, the DP1 should also be looking down the middle of the two cars and see both sides to some degree. The DP1 looks shifted slightly to the right, relative to the DP2, which is why the side of the hyundai disappears.

It's a tough comparison anyways, as you have to make a choice between moving the camera or cropping an image to generate a similar view between the two focal lengths. Neither choice will satisfy everyone.
