Actually I'm no longer posting because I'm tired of posts like yours. Im tired of personal attack. I'm tired of trying to help on my own time. I haven't been so silenced by anyone other than those of you that spew personal venom and vitriol instead of trying to talk about the issues faced in a logical and scientific way.

Why should I engage with people like you ?

Notice too that many other regulars aren't posting.

John, I hope I didn't post anything that annoyed you. I just got my UM46 and have a lot to learn about it. So far I am impressed with it and I haven't seen anything to alarm me other than there was some debris on the view finder display that would not shake off. So I had to send that back, but it and everything else is impressive.

John, as far as I remember you decided to stop posting when someone suggested that instead of you, someone from BMD should be answering the magenta issue. Before that there were posts, to and fro, on the issue and you, a prominent beta tester of UM46, were defending the camera. Some tempers could have gotten frayed in the process, but that happens in every forum. We all waited for this magical UM46 for so long and if some people have got faulty cameras you can't blame them for the frustration.
However, I sincerely apologise if I have hurt you personally through any of my posts, that was never my intention.

Now that someone from BMD has acknowledged that they are aware of the issue faced by some people and looking into it, I hope things would be solved sooner or later. I keep on visiting this forum to get that great news from BMD so that I can go ahead with my decision to buy the camera.

We get you JB, It's not your fault, and we appreciate you more than you know,
I'm not being sarcastic but you are acting as if
"The majority of us are guilty of attacking you" This is not the case (with some exceptions).

JB you're about as liberal and camera agnostic as one can be,
I think your problem is "Letting It" get too personal, you have an attitude that makes you look
short tempered at times, We know how this happens and it's not something anyone like you who works hard and succeeds should be ashamed of, You are a great DP and you are a great person who shares great knowledge with the rest of us, and it is always appreciated, but not always returned to you because people are frustrated or angry with Some BMD Camera updates and delays.

I agree you must be exhausted with the personal attacks, and tired of trying to help on your own time.
But we need you, and we do appreciate you JB.

FYI: This is in "NO" way me trying to make up or apologize for my own misdeeds with you JB,
I'm just in a better place in my life now,
and I look at you as successfully helping many other while on your own journey.

Keep up the good work JB, It will pay you back ten fold!

Personally I didn't engage any personal flame, nor tried to shoveling muck on the company, instead I tried to give all my help sharing my findings on this issue: I was the first reporting here that slow aperture past f8 increase the defect, and I discovered it spending a whole afternoon on set trying different lens and cameras in a controlled light environment.
I'm really always on the side of propositive-collaborative-let's help finding a solution together, but I'm keeping getting answers like "the camera works as is intended to be", when I would just read two lines as "We are sorry for this inconvenience, as for today we didn't found a solution for this behavior in certain situations. The clips you showed us are absolutely ruined and far from BM desired IQ. We're working pretty hard to understand why this happens, meanwhile we hope you can still enjoy your great camera while waiting for our fix very soon. Thanks for understanding"

But then, if other customers got their cameras replaced for the very same issue, why I can't? I've waited more than two weeks (and camera not shipped back yet) just for them to try it. That's unacceptable.

Sorry if my post above seems random: I wanted to test if my posts are still being moderated (new user) and if I could post URL's.

Anyway, I posted this URL

www.l-camera-forum.com/topic/153464-towards-an-explanation-of-the-italian-flag-phenomenon/?p=1758723

on p25 of this thread as well. It directs to a Leica forum thread, discussing what is called the "ITALIAN FLAG PHENOMENON" in Leica M9 cameras. As I have stated, I do not claim that the LEICA problem is Identical to the 4.6k problem, although there seems to be striking similarities.

The URL above will take you to the second last page on that thread (p10, where the user "denoir", with post nr196, offer - what seems to be - a plausible explanation for that problem via a quote.

Great find! Sounds like what others have said here already. Seems it really may be in the sensor design, which would also mean it's all of the sensors in all of the 4.6Ks. That's unfortunate, because the only fix would be a different sensor, which would take BMD quite some time to design, test, and start manufacturing in sufficient quantities. Guess it's time to give up on this one and look elsewhere...

That was a good read Jaco, thanks!

In the Bayer pattern the red "clots" of absorption dye are slightly larger than the blue&green ones. They're still "square" as in equal width and height, but slightly larger.

The sensor surface underneath however, isn't rotationally symmetrical. The ccd vias are slightly rectangular, the Y dimension of the active pixel surface being larger than the X dimension. This is the same in all of the Kodak 6.8µm sensors, dating back to the "original" in the Oly E-1, 2002. They try to mitigate some of this effect with ITO gates and metal masks on top of the sensor (to stop some of the colour crosstalk via pixel>pixel light spread), but there's also the question of angle/wavelength imbalance.

If you balance the QE so that you have one "correct" whitebalance for perfectly perpendicular incident angles, the Kodak construction will by construction default unfortunately not have the same WB for incident light with lower angles. If you shine a white light source with perfect collimation (all light travels in perfect, parallel lines in space) on the sensor - first at 90º angle, and then at 30º angle - you wouldn't get the same WB result... Even though the light has the same CCT in both cases.

This defect is aggregated by the use of quite thick (not the best materials...) colour filters and assymetrical cell structures (the blue cell is even more assymetrical than the other cells, red is almost square) and you get angle-dependent colour faults.

PREDICTABLE colour shifts, if you know the lens chacteristics, but even so.

To get the filter layer to work properly with light with high incident angles, the "normal" case you need to deposit them fairly centered over the active pixel areas. Unfortunately this means that they are DE-centered in the case of light with lower incident angles, due to the assymetrical nature of the CCD cell construction Kodak uses.

This decenterig means that you get one dominant colour fault in one direction from the image center, and the opposite colour fault in the opposite direction. And since the blue channel has the smallest active pixel surface, it has the lowest asymmetry. R-G shows a lot more deviation from corner>opposite corner.

The colour filters are not placed exactly over the center of the pixel (that's square), it's placed over the center of the active pixel surface (that's rectangular, and not equally transparent for all wavelengths).

So it's just as much a question of non-equal vignette as a question of colour "leakage". And the sensor is asymmetrical in construction, it isn't even mirror-symmetric in the horisontal direction if you look at a FEM side view. Red wavelengths have a much higher penetration capability, so it can go straight through a passivation layer, but not a metal. So one side of the "blocking" parts of the active pixel surface is transparent to red, the other isn't. The "red" transparent window in the pixel surface is pushed over to one side of the square containing the entire pixel, while the blue "window" is centered on the square.


In that thread people speak of "italian flag" issue.. And looking at white wall shoot with saturation/vibrance +100 .. I can see a little of my country

If the problem lies with the sensor design, yes, then it is unfortunate. Hopefully it's not and a more benign cause like coherent interference of light waves from the cover class is to blame. Regardless, I know BM is burning the midnight oil (in fact, I think they are working around the clock in shifts) trying to solve this issue.

When the pocket camera exhibited the white orb problem, many believed that the sensor was "blooming": that the charge from a saturated pixel over-spilled into neighboring pixels. However, BM was able to fix the problem with a calibration adjustment (whatever that means). So, for now, all explanations or theories are speculation at best.

I think Kristian Lam's post is a step in the right direction.

I can understand John's frustration. The best word ever for this is GATVOL. A word I use quite often.

from urbandictionary.com:

" gatvol
Pronounced: gaaat-fall. Meaning: very fed-up or irritated.
It is a South African word, derived from the Afrikaans language, but widely used in English (and some indigenous langue conversation.)
Literal translation: gat(ass or hole) vol(full)
Probably intended to mean a dug hole full to the brim (“up to your neck with…”) , but given a slant by the double meaning of the word “gat”.
I am gatvol of the way my boss treats me. "

I have been gatvol of this forum many times.

Referring back to the Leica forum, reading through the whole thread, what struck me most was the "civil" manner of communication. I don't spend that much time reading forums and apart from a few posts on Apple's support forum, this is the only forum I have ever posted on. In comparison then to other forums, I don't really know how the BM forum compares in regards to mutual respect. I also have made comments on this forum which I retrospectively thought were childish, which I regret.

But respect goes both ways. Asking a question or stating a concern - regardless of how stupid it may seem - needs also to be respected.

John, I'd really appreciate if you would not stop posting here. I've always enjoyed reading your postings and/or having a discussion with you. I think some people here are just frustrated with the current situation and have projected their frustration into your online appearance in the lack of BMD officials here posting.
I am sure in real life if we all would sit together we would have a beer or two, a lot of fun and some fine discussion.
Saying "Thx for help!" is not a crime.

This is true. Since JB is seen as probably BM's foremost ambassador in the cinematography fraternity, what people perceive is John Brawley = Blackmagic Design.

Tarek, this is the million dollar question, isn't it? If there are, then the solution to the problem should be easy: simply correct the cameras with problems to replicate the good ones. Then also, it can't be a sensor design problem.

Having said that, I don't believe you will find a truthful answer to your question any time soon. I still want to buy this camera [although it will cost me almost twice the price of what it would have cost since when the camera was supposed to be released due to my country's falling currency] and really hope they succeed.

See when you say this, I take this as a personal attack.

You're saying I'm some kind of attack dog. I'm attacked for not posting and attacked for explaining why I'm not posting.

You see how idiotic that seems right ? Your kinds of posts are why I'm not posting just to re-iterate.

JB.


John, your information is quite valuable given the fact that you have spent time with the camera. Not because you worked for BMD on the project.

People will always seek a patsy to beat on when frustrated. In the eyes of the Jack Rubys you will be the one to beat on regardless of what you say in your posts.

Mind you, though that there are readers and posters here who are speaking to you from a the perspective of you having spent time with the camera and don't consider you a punching bag.

The minute you made that public film for BMD you crawled into the lime-light which we all know has its ups and downs. We tend to enjoy the ups and if not careful break on the downs.

Dont let the downs intervene with your objectiveness. Ignore the chatter and thrive on the things that matter ;-)

Jaco from what I understand if there is a sensor design problem so all the cameras are faulty above f5.6 or f8

Well, therefore non-alcoholic beer has been invented :)
At least here in Austria breweries are offering a diverse palette ranging from non-alcoholic dark to white and natural beer. During the hottest summer days I prefer some bottles of those as it gives the refreshing taste without the regret.

The issue of Magenta has been confirmed in my case.

The German Distributer quoted this after getting the information from Black Magic Design UK

The Camera was inspected and the malfunction was confirmed. On one hand they would like to repair the camera on the other they don't know how to do that. On top of that once again they have problems with bottlenecked supply. So a replacement could take just as long as a reparation


It has been 3 weeks since I returned the Camera for NDA and this is the information I have gotten since that date.

I'll update as soon as I get news.

@ JB: I have always found your posting insightful, John.

I hope my saying that I've noticed the beta testers haven't chimed in on this since it was confirmed to be an issue didn't offend. I actually understand why a beta tester wouldn't want to say anything until BMD figures things out (or maybe you're helping BMD figure it out).

I think it is good for both "sides". For you, as you now know your cam will be fixed. And for BM and the community as that will reduce the vacuum that filled by the rumors every day.

I am happy for you that your case is finally on it's way to be solved.

This thread and all posts within will remain on topic or there will be warnings/bans handed out. There is no place on our forums for personal insults of ANYONE. The reason for these forums is for assistance and constructive information/guidance on things related to the products.

In regards to the subject of this being a wide spread issue, we understand there are people with concerns about their cameras and we are working diligently to address this however there are a lot of cameras that are out there doing amazing things. We've had music videos and NY fashion week shoots done and have had amazing results.

At the end of it all, we want to do right by you as the owner of our products so thank you to those of you who's helped us by providing the information our support teams have asked for. We are forwarding everything along and will update you with more information when we have it.

Maybe, maybe not. We will see. My UM4.6k looks fine to me in any real life scenario. But Mortons was a bad one so it is good to see he got help.

Hopefully it's not and a more benign cause like coherent interference of light waves from the cover class is to blame. Regardless, I know BM is burning the midnight oil (in fact, I think they are working around the clock in shifts) trying to solve this issue.


It doesn't really seem like it though. It's been, what, a month and a half since this issue was reported on production models? Almost 6 months since it was first reported in beta footage? And they still don't have a clue what the cause is. They knew about the issue and shipped the cameras anyway. To me that seems like they don't really care about it that much. People are still buying the camera and a lot of those people won't notice most of the time and/or just aren't aware. I think BMD will keep shipping the cameras as is without changing anything, but will do a V2 sensor in 6 months to a year like they did with Ursa, maybe also finally including global shutter and may even charge more for it.

They haven't actually confirmed there's an issue. They've only said that they are looking at reports and forwarding them to engineering. That's all. That doesn't mean the agree there's an issue or that they are doing anything to fix it. It only means they are investigating the possibility. People are getting their cameras that clearly show a major problem returned to them with a statement that says it's operating within specs.

It's a real bummer, because this could be a really great camera. I am tempted to order one, hoping there are actually good ones since I have seen some great footage from it, and if there's any issues at all just return it for a refund. I rarely shoot above T5.6 and usually prefer to be a T2.8 and below so it may be just fine for me. I just don't want any shots ruined at the wrong time. But some of that great footage I've seen could be shot at 2.8 and so don't show the issue even though those same cameras do have the issue at 8 and above. Hmmm...

I got my replacement camera from B&H today. Sad to say.... Still magenta. BUT. It is actually better (believe it or not) than my last camera. Still, varying degrees of better or worse are not super exciting. I was hoping that what some of the BMD voices on here have said is true, and that this is a small issue that is being trumped up by folks on this thread. But what are the chances that several of us have gotten a "bad" sensor, after having exchanged our cameras, if the problem is in the minority?

Scott, great to see the improvement. If all cameras were like that, we wouldn't be having these discussions at all. And I agree with Tony, and others, who have pointed out that there do appear to be good cameras out there, even using a 35mm lens. Understand the great frustration (and financial consequences) with delays or repeatedly receiving a bad camera, but one day it will be resolved. I think our expectations were that this camera was going to produce an image as perfect as one could imagine and only $5/$5.5K! Okay, for many it hasn't worked out that way but it is there already for some so we know it's possible.

As for accommodating the flaws, that may work for some, but it's not the right thing to do in the long run. You buy a 4.6K sensor so one day you can use all those photosites to create the best image possible. Sure in 4K/UHD and lower, the sensor is likely already there for nearly everyone. But BMD won't give up on this.

You should have read the post I posted earlier.... This info comes directly from BMD

The Camera was inspected and the malfunction was confirmed. On one hand they would like to repair the camera on the other they don't know how to do that. On top of that once again they have problems with bottlenecked supply. So a replacement could take just as long as a reparation


That is clear-cut confirmation !

Actually, that's your dealer saying that. What did BMD tell your dealer verbatim? A lot of context gets changed as word travels from person to person. BMD could have easily told your dealer the same thing they've been saying on this board to people who have requested RMAs, and that mistakenly gets taken that as BMD admitting there's a fault, when they've multiple times have said they are investigating the issue and will let us know when they have something to say about it. They've even sent cameras back to owners telling them they are working fine and to specs when they clearly are not.

you seem to know am awful lot for someone NOT being there and NOT even owning a camera.

The quote is as I said earlier - DIRECT from the German Distributor AFTER getting the info from Black Magic.

Exactly, that's the word from your dealer after getting info from BMD. They could be misinterpreting what BMD is saying as confirmation of the problem (like some on this forum to BMD's posts in this thread), when in fact, BMD has not said anything confirming the problem. Read BMD's posts in this thread. The words are carefully chosen to make sure they aren't actually confirming a fault.

If BMD service is saying they confirmed the problem then why isn't anyone from BMD here saying it? Why are no other camera owners saying BMD is confirming it? That quote you posted is from your dealer, not from BMD. If someone from BMD wants to come on this forum and say "Yes, there is a problem that we are confirming" then great. But they aren't doing that because they aren't confirming there's a defect. Everyone is saying that BMD is going to fix the problem, with nothing from BMD actually showing that they're going to.

This is simply not true. This conjecture keeps being repeated (regurgitated) yet there are cameras out there, including mine, which are working fine without any problems.

This may even seem to be a case of the voice of a minority being louder than the majority. I really think the majority of people have no need, or desire, to use forums.

I second that notion. I can't tell if this one has the dreaded Magenta corners or not. Please see if you can white balance this image with the global tint and re post.

I just got my replacement camera (2nd) but I am not in NY to test it till Tuesday. This image is actually giving me some hope but that remains to be seen..

At this point I can guarantee that the good cameras are the minority. I have gone through two cameras so far and I'm waiting on the third. I have friends/coligues who have returned roughly 6 cameras, not to mention other friends who returned for other issues, not involving the magenta issue (which I'd still classify as a bad camera). I mean, If good cameras were the norm the statistical probability that in just the group of individuals that I know roughly 10 cameras were bad is astronomical.

I did this quickly in photoshop with just a global adjustment.

I thought maybe there still looked to be some magenta on the edges so I pushed up the saturation very high.

It looks totally fine to me. What lens and settings did you use?

There is still magenta in the corners and sides not present in the middle. This camera while not nearly as bad as some, still has the issue.

You are reading my text with your eyes wide shut, my friend. I stated the German Distributor NOT my dealer.

A confirmation is NOT a confirmation just because it was posted on an online forum. I actually regard higher a confirmation coming directly from the office than some posting it on a forum. You can demand all you want a public statement on this forum. I regard what I received as a confirmation that something was indeed wrong with my camera. And given the nature that my camera suffered from the SAME issues all the others have been reporting... The conformation is real.

If BMD cannot pinpoint the issue - they can't very well address it in a public statement, can they. This very thread if full of BMD Official Confirmations. All you need to do is LOOK. They are confirming that they are looking INTO IT. They would NOT do that if there were NOTHING to look into. And until they find something there is nothing further to confirm.

If you are hoping or looking for a different kind of confirmation or statement, then that is your thing ;-)
IMO - until they find the shooter on the grassy knoll - I don't expect hearing publicly form them again.

Exactly, its better, but its not perfect.

It is usable, but I'd still like to know that BMD will stand by their camera. I'm worried that they won't say "hey everyone, no need to keep RMA'ing your cameras. Hold on to them, we will fix the ones not working right.
