Hello everyone,

following all the messages and polemics regarding the DP3 Merrill's colour rendition and whether it is different or not from the DP1/DP2 pair, I proceeded to a controlled test that should put this discussion to rest - I shot colour charts under controlled flash light, using different WB, computing all colorimetric values in PS, etc.

In short, the result is that there are in fact differences; especially so if you use Auto WB or WB Presets, where the DP3 is much better than the DP1/DP2, much less so if you use Custom WB in which case, actually, the DP2 and DP3 are very similar, versus the DP1 which stands alone in this case.

I posted the whole test, colour charts shots included, on my blog HERE for your reference.

Hope this helps to clarify things on this heated issue

Best,

Vieri

I think it was a very revealing test.  I think you did a very good job. I don't recall any controversy in the Sony forum about color accuracy between all its plethora of 16.1 mp Nex cameras.  Each camera performs differently, each newer generation shows improvement and better color accuracy. So if I'm to understand this---we expect Sigma to revamp the DP1M and DP2M cameras to have the exact color calibration as the newer generation DP3M? and in addition Sigma should do extensive costly firmware updates of the DP1M and DP2M to bring them up to the color accuracy of its newest generation DP3M?

So I should post in the Sony forum and complain that Sony isn't doing anything to improve its older model"s color accuracy and expect a new firmware update to bring all the older models in line exactly with the newest model because these camera have the same sensor etc?  Is this a realistic expectation of a camera manufacturer?

Seems to me that that the lesson here is that if you are going to be out shooting with all three cameras hanging around your neck--you better do a custom white balance.

When shooting wedding with different camera models in the same brand---I always did a custom white balance.  Saves headaches later.

Each model is clearly an improvement over the earlier one in the auto balance performance---I can see a difference between each camera release based on the color charts that you shot. Its good to know that there are difference in performance using Auto WB between the three cameras.

Not sure how heated this issue is or how big a controversy this really is, but I appreciate your hard work and write up!
