It is a film photo. There is no mistake. It came from a source which stated that. It really doesn't matter whether it's a photo of a painting or not, the point remains that purple/blue colors are quite normal when photographing animals with black coats in natural light.

The characteristics of the purple/megenta - green blotches of Foveon are very very different from what you are describing with other cameras and the animals. This has been discussed before. Mysteriously enough those blotches of Foveon have shown in rock, buildings, and others with virtually the same pattern.

You obviously have no idea what the discussion is about. The question was raised concerning an image Laurence posted which depicted Black Angus cattle in a field. The slight bluish color on a couple of the cattle was precisely what is found in normal images of black coated animals under natural light with blue in the sky reflections.

This isn't a subject issue, it's a Foveon issue and it's very characteristic. Of course, you never recognized this with the Merrill, so at this point after wide spread recognition by the likes of Quentin and others who were applauded for their Merrill love and work, I think it's pretty safe to say perhaps you either lack the skills to see it or just plain out deny it.

I think it's pretty safe to say that you see color issues everywhere you look.

Nope. There are some images I have pointed out do not have them.

A perfect example is the very first DP2 Merrill image I posted where you complained about "blotching" in the asphalt which was due to reflections from oil impregnation.

Nope, the pattern was rather obvious and it wasn't just in the asphalt. The funny thing is that instead of keeping the original you decided to change it after the fact.

I removed it just to shut you up and you have been on a crusade about blotching since.

Nope, I was pointing this issue out well before you showed your image. It really has nothing to do with your image.

I live where the image was made. I look at the pavement every day. I know from first hand personal experience what the cause of the color was.

Yes, there is sometimes blotching in low light. There is also normal magenta, blue and purple colors in nature. You seemingly don't know the difference.

I do. Like I said, there are several image areas and other images I have pointed out the phenomenon does not occur or is small enough to be of concern.

My skills are quite equal to your skills in photography Ricardo and I've been doing it a LOT longer than you.

I don't thin you have prevent that. Not even remotely close. If they are you sure come very empty handed with hardly anything to show. Me on the other hand I post images constantly that I am taking, well, constantly.

See, it's easy to say a bunch of stuff on the internet with nothing to back it up for. I even said, if you have an awesome gallery somewhere with your photos by all means post it, but if you come empty handed and that's all you can do, doesn't seem like you have proven anything.

My clients for many years were art galleries and museums who required as close to perfection in colors, lighting and reflection as humanly possible, and I have never had a complaint.

Again, all words on the internet. You have shown nothing in this regard. It's all your word.

The difference between us is that you do not recognize the differences.

I believe your assessment is quite mistaken.

Now if you want to discuss this, go back to Laurence's image and look again because I don't believe you have a clue about what is being discussed. It's just another example of your jumping on the color blotch bandwagon in my opinion.

It is certainly possible I jumped prematurely in this particular sub-thread. I will give you that much. See? I am capable of admitting if I am wrong. Never seen you do that and you are certainly not perfect unless you aren't human.

The other points I mentioned still stand.

Never mind that others like the snow example with magenta stuff has been show before next to a DP2 sensor that shows what it should- white.

Snow reflects blue sky light Ricardo. I live in snow country. I probably see more snow in a month than you've seen in your entire life. You simply haven't a clue.

I have been in Minnesota for a while. Quite a while, to know that in good daylight snow should look white, and not magenta. The issue was raised by *someone other than me* comparing his Merrill with previous Foveon. He posted the shots side to side. It was pretty clear.

Of course, he did one thing you haven't done- post pictures, post evidence. All you post is a bunch of words. I post pictures. Where are yours?

Let's see them. You claim you have equal skill, come on, show it. Where are your photos?

Update: There were many images being reference, not just Laurence's cow shot. But yes, those cows do show some rather typical Foveon botching.  Yes I am aware of animal furs creating color patterns but those say "Foveon blotch signature" from a mile.  They are not has horrible as some other situations though. So look at that, I wasn't even wrong after all, but I do agree I should have verified more of the subthread first.

But still, let's see your photographs. Let's see the proof of skill here.  I more than welcome to be surprised, I always like good photography.
