Vertical banding - what could it be?

[Geoff]

Although not hugely obvious it has become a little bit of a concern to me that in some recent shots I've seen some vertical banding.

here's the first shot where it's not so obvious: (shot with SB800, 1/60sec F4.5 and auto WB, ISO 250, focal length 31mm).



and the 2nd image where I've upped the exposure so it's more obvious to ppl here. Anyone seen this b4 or got any ideas? I think its' particularly obvious above the girls head on the left as you look at the photo.

I couldn't see it on my primary LCD but as soon as I dragged it to my 2ndy one the banding stood out like all buggery, and only at ISO 250 hmmmmm

[DStrom]

I have seen a similar type of banding in some of my shots, though this only seemed to occur when I had under exposed the shot and attempted correct it by PP the image. Not in normal shooting.

I must say that the original RAW file doesn't look to bad but I did want to up the exposure a little, as soon as I did I saw this horrific banding. Not too happy about it either.

vertical banding.

I thought the banding was usually seen horizontal?
Were these taken in portrait orientation?

[MattC]

Geoff,

I would call that horizontal banding - made vertical by camera orientation.

Yeah, that's what I was thinking.

I was sure there was some discussion about this banding ages ago but can't find it using the search.

I've also seen it in some of my underexposed macro shots.

Yeah...ok so horizontal banding and I made it veritcal

I also tried to find something about it in the search too, couldn't find anything. Oh well - something to look out for I guess.

Geoff,

This is the only thread that I recall on the subject.

maybe give maxwell a visit

[Glen]

Geoff, I remember some discussion and have had that myself in very dark areas of the image. Not actually sure if it is a problem or limitation of the sensor. It has happened to me in occasions just like that, a well lit foreground and a dark patch in the background usually using matrix metering or spot.


It really is one of you cameras just saying - replace me with a D200, I'm not up for this

Glen - hahahaha...u might just be right!! Yesterday I came soooo close I say that as I wait for a someone to to come with an airconditioning quote for our place Hoping it'll be a bit cheaper this time of year for installation/supply etc.

[Glen]

Airconditioning! Just get a metal garbage bin and you can have an open fire place. $20 from Bunnings, change can be used for D200

Geoff,

My D70 has exactly the same problem at the moment.
I took some night shots of the Oh last week or so and they all have horizontal banding on the top iof the image, in the same place as yours would be if my camera was rotated to portrait.

I don't know what it is either, but it;s incredibly noticeable

[Matt. K]

This banding seems to pop up occasionally....but very infrequently. It may be that the camera was affected by a source of magnetic radiation or some other electrical interference. If it happens often then obviously your camera is stuffed. Dont get overly concerned unless it keeps happening.

OK Matt - u can buy 2 x D200's for the price of one and give one of them to me? Timing is good

[sirhc55]

Does it happen at other iso values Geoff

[Geoff]

Does it happen at other iso values Geoff

There was another shot yes, with ISO 320 and it was as evident as that shot.

Might have to experiment a little more and see what makes it better/worse.

[DStrom]

with my camera it occurred at iso 200.

I guess you just need to determine if it is a regular occurrence and how intrusive it is.

None the less it would be a good excuse to justify a D200/D2x to your other half

She doesn't take much convincing - luckily for me

Some people have all the luck

[gstark]

Geoff,

Have you tried using fresher film?


Seriously, what about trying a different in-camera curve?

Might try a different in camera curve yes - will test in the coming days and let you know.

I find wearing a tinfoil hat whilst taking pictures can help prevent this - (it also keeps the aliens' voices in my head a bit quieter)

I tried that but the voices said they could still see the banding

[nito]

I see that type of banding tooo on some shots. Ignore it and it goes away. I attribute it to noise at high iso, because for me it only happens at 800 and above.

[Justin]

sunspots, sleets of neutrons burning through our sensors - that's what the banding is, the path of the neutron. If it's horizontal, you've got tachyons and vertical, you've got moryons

[Grev]

Like another person has said, I think it's the underexposed background due to flash and metering problems.

[stormygirl]

The same thing has happened to me too. I shot this at ISO 200 with the in camera noise reduction ON. I was attempting to capture some very distant lightning....and I know the horizon is crooked



I had taken about 50 images that night, and this was the only one that suffered the horizontal banding. I have since turned OFF the in camera noise reduction function and have not had the problem since. I don't know if the 2 are connected in some way....or whether it's just one of those things!!

I thought that this was how the Melbourne night sky always looked.

It usually does for me, after a few vinos on Lygon St, at any rate.
