Banding? Fine with me.

Maybe you could elaborate a bit more on that "demosaic" theory... why would it have more impact on banding than the interlaced blooming caused by the multi-channel reading in opposite directions?
Ok then, is there some other forum you could tell us about where we
can read better analysis of this artifact? (and others)
what exactly are you interested in about banding? please put your
questions.

like as if canon doesnt ahve banding issues of their own i saw a link some forum where chuck westfall basicly acknoledged that the 5d has banding issues too
This topic has banding... I can see it... it's definitely defective.

Totally unrealistic and unecessary. You show very little
understanding of what people are talking about here. It's sad :(

I'd really like to see everybody just getting along fine, trying to
help each other. Isn't that why we are here?

Muhammad Ali in his boxing prime was a lightweight compared to you. :)
I enjoy your comments. Thank you.

It is so good that your managed to give the whole discussion the right direction.

Now we all understand banding clearly.

I never said that "it have more impact".

What I said is - greens are read into the same direction. Green channels exhibit "normal" blooming. Demosaic based on the fact that green channels contain higher resolution data and that they are not affected with artifacts to the same extent as red and blue channels is the preferred method. It is true in respect of many other artifacts, like moire, too.

Let's cut to the chase here. What I'm getting from this discussion is that blooming and banding are both caused by demosaicing algorithms used by the camera while moving the image data off the sensor. Because the D200 is doing it in two seperate directions and one side is getting the green channel that catches different light frequencies than the opposite side that is getting the alternating red and blue channels -- that's what causes short banding. If I understand this correctly than it makes sense to me (although it's all technically over my head).

Now, regarding the blooming versus banding issue. Blooming is the same issue only because the blown color channels are all being read in the same direction, so they bloom instead of band (all the "bleeding" goes in one direction). So, my question to Sergio is this: have you done your lightbulb test on the D70 and has it bloomed? If so, than it would appear that the D200, while not perfect, is an improvement.

I thought you would have figured out what I was saying, but apparently not. Oh well, it isn't the first time that I was wrong.
 
Yes, other cameras just bloom where the D200 bands... my D70 does it, and you can look here for a D100 example vs D200:

julia, you are like water slipping thru ones hands, oh how we want to understand that which enchants us, please explain more for us what do you mean.
 
That since you returned your D200 and happily kept your D70 that you will return to the D70 forum? That way, they would get the benefit of your vast knowledge and experience.

Vulture, maybe. Cultured, probably not so much.

I've never left the D70 forum. You wouldn't know a lot about where people spend their time, having just recently popped in here in December. I may either repurchase the D200 at some point in the future ("ifs" listed in other posts), buy a D2x, or await an iteration on one of the two. In the meantime, I'll do what you do...go where I please. I've never made any pretension to "vast expertise" (or ANY expertise) so your sarcasm (weak, by the way) is wasted. Anyone smart enough to attempt sarcasm should be capable of skipping posts they don't like, and dialogue with people they disapprove of. Are you? We'll see.

From what I have heard, much of the banding disappears when prints are made while blooming does not. It is also my understanding that the D200 bands less often than the D70 blooms. So, while I would consider both of these to be a problem; banding is a minor one in the D200 while blooming is a much more significant one in the D70.
