freaked out.. what is that?

[saravrose]

so, playing with my new lens took quite a few of these flower pictures which isn't something I normally do.. but, what happened here? what are those lines? did I do something here? this has never happened before.....

Banding... Ughhh... Assuming you wern't standing on top of a radar installation, time to send it to canon (the Body)

this is the only shot that I saw it on.. banding? okay.. new to DSLR's explain that to me please? without making me panic...

Ignore it if it only happened once. You could take out your batteries and put them in again, install latest firmware or reinstall it and format CF cards if you feel like it, just in case there is a glitch somewhere. What's the new lens BTW?

[saravrose]

here are a few more photos all taken within a couple of minutes of eachother... all i'm seeing on these is bokeh... tell me if i'm wrong..

28-105mm 3.5-4.5..... I'm really liking it so far.... so you don't think it's a big deal Dave??? what exactly is banding? sorry to bug ya I just don't know what it is and my searches aren't turning up any answers....

maybe your cell phone did it... ever think of that? huh? did ya? i just did, all by myself.. i did... lol

seriously, i have a nextel and this thing interferes with just about anything electronic.. tv, radio, computer, //// its a drag!
just a thought.. could be something else though, i hope its not the camera...that would be a drag too.

mine can be in my pocket and it interferes with stuff... its a nextell so its got that walkie talkie function and i think its putting out some type of strange signal... ill be driving and the car radio will freak out every now and then, or even better, ill be in a store, walk past the tv display and they will all start making this noise like a machine gun like chai-chai-chai-. its a hoot! i was just thinking that might have done it as it looks like some type of interferance to me. Perhaps it was just a "burp" in the camera system... stranger stuff...

What are your in camera settings? Some of those shoots look very over saturated. Banding can sometimes occur in conditions where there is high contrast and saturation, in particular lighting conditions, because of camera settings impacting on these, and when you do a big enlargement esp on your monitor. I'd do what I said above. Also, don't use your in camera settings, sharpness/saturation/whatever for 'post-processing' unless there is good reason to do so ... and shoot RAW if you don't already. This gives you best chance of the best IQ. Nice lens that one. Will get you some good results. Is your monitor calibrated too?

LoL... thanks, just had my first laugh today, and only awake for 15mins. Lovely! :D

no.. postprocessing.. nothing serious I was just playing around and obviously it's not a photo that I really need.. I posted the other's to make sure that the DOF that I was seeing wasn't actualy that banding issue.. I'm going to say that it was either my cell phone or a fluke because every other picture that i've taken on that day isn't showing anything icky... I was in AV with ISO 100 I believe... but it was a crowded area and these were in flower beds.. thanks for the advice I would hate to have to send my camera to Canon however long it'd be away would be too long...

Actually, that isn't banding. Banding is more a factor of the Digital rendering of your images. It can happen anywhere on the chain of manipulation that is done with Digital tools, including tools used merely to view the image.

It is when, instead of seeing a natural sweep of color, hue, and shading in your images; you see lines that appear to be more abrupt color changes. These lines will follow the pattern of the color changes. An easy way too quickly see banding is to change your display to 256 colors. This will limit the ability of your monitor to represent your image.

What you're seeing is electrical interference that struck at the time your camera was digitizing that image. It can be from many sources (so, so, many in today's world where there are literally thousands of electrical signals passing through your space at any given moment) including your auto-focus system and lens. I don't have time to find links, but in their have been products where this is a continual issue.

Obviously, what ever interfered with there cannot as it was taking that picture it was limited, so no need to sweat.

When you consider the millions of gadgets; radio, television and other broadcast signals,; microwaves; the electrical and telephone wires; and myriad devices generating he electrical fields that I haven't mentioned or even thought of - it is amazing that the issue isn't much more common. Hats off to today's engineers! Especially Canon's engineers!

thanks soo much for the information.. and that's a scary photo, did you manipulate it to get that effect as an example or did that actually happen?

What Hardcard refers to is banding or posterization.

What you have there is refered to as vertical banding and is usually caused by uderexposure in the shadow or high contrast areas of an image. There is nothing wrong with your camera.

This is certainly an very odd effect, but it is not "banding". It looks like posterizaton to me. Were you tinkering with levels or curves to make this example.

Enjoy! Lon

[wolf]

Yes, that is banding (posterizaton). saravrose's example is know as "vertical banding".

In your example from 123di.com the observable “banding” is in the display of the histogram (not the image). But, the observable effect in the images shown is posterization (not banding).

Enjoy! Lon

[saravrose]

okay.. so the final say is that nothing is wrong with my camera right?

[The Hardcard]

Well, I don't know if the term is used as such everywhere, but it is very common to for it to be called banding. Posterization is just very extreme banding. It is often much more subtle.

I am not familiar with vertical banding as you have defined it, Wolf. In the afflicted image, it goes pretty far into the light areas. Only the white areas of the petal are not very visibly affected. I am not sure it is an underexposure effect.

But practically, saravrose, it isn't a camera problem.

A good accurate read about posterization will reveal that it is also referred to as banding. http://photography-on-the.net/forum/images/icons/icon12.gif

Any way saravrose there is really nothing wrong with your camera.

... its a nextell so its got that walkie talkie function and i think its putting out some type of strange signal... A Nextel phone is nothing more than a normal phone as far as the transmissions go. The "walkie talkie" function is simply how one connects to another user - a function of Nextel's software, not any real change at the phone level - combined with hands-free audio. The phones do NOT directly connect with each other - it's all through Nextel's "cellular" system.

In other words, your Nextel phone will not cause any interference with other things that any other "cell" phone wouldn't do.

its funny, in the car, i can tell its gonna ring just before it does, the radio starts to stutter (for lack of a better word) and when im at my dest, the computer screen will sorta flicker every few minutes or so, and when i walk past a TV or radio, it will interfere with the signal. I had an under cabinet CD player/FM radio, and even if it was switched off, it would make the same noise... like a staticky sound, when i walked by it. Im thinking it was the signal from the walkie talkie as my wifes Verizon phone doesnt seem to have this problem and neither did the sprint i had years ago.. and this is my 5th. Nextel and they all did this. Although i have never had it interfere with a camera, i guess there is a first time for eveything.
