hi everyone,
i found this rare texture in my image today, i dont know what it is, i found it before but real sutil and only in a little part of the image, but this one is like 1/4 of it and that freaked me out .
i made lots of pictures today, like 10 in whit different sutups and locations, and the strange thing is that only those had that textures, i made o couple of one whit the same exact setting an no problem and the wierdest thing is that i return to the same exact spot and take one picture again and the texture apear so? what do you think? please help!

I'm so sorry, but I haven't seen anything like that before. It's not like your typical noise or noise to an extreme.

My husband was wondering if you were near anything that could be giving off a lot of interference, like a radio tower. (personally, I can't see how that would affect anything...)

That's bizarre. It seems to be a write problem of some sort, interference actually seems to be a reasonable possibility to me, but I'm no expert. I am gonna contact Kirbic to come look at this, he is very knowledgeable...

OK, I sent a shoutout to Kirbic, give him some time.

I have seen radar on a boat affect a Sony handicam in a similar manner, but I was standing on the radar bar, about 5 ft from the antenna.
The only other things that I could imagine that would do that would be moisture, a glitch with your card, or shooting a printed item that was printed with a dot style printer. Our eyes don't see the individual dots, but the camera can, and if the dots nearly line up with the sensor cells, it can cause all kinds of squiggles and dots.

Bear in mind it's a holiday weekend in America and he's (I think) a family man, so he may be slow to respond...

I was an intelligence photographer in the Navy and when onboard ships would get a texture like that in photos when they had certain radars on. If you only got the texture when shooting from one location I would have to say it is some sort of radar interference.

I've seen it a few times, usually interference from outside sources causes the issue. I'm trying to dig up a couple of older posts in another forum that shows it as well. Likely the Radar or some other frequency caused it. I remember one that was caused by a cheap wireless flash trigger.

oh, come on now! Are you saying that my husband was right?

I hate it when that happens!! (but he's a physicist, so I shouldn't be surprised.)

lol, indeed! to much radation!

I think y'all are on exactly the right track... radio interference from some nearby source. The 5D is moderately susceptible to it, seems to be a little more so than some other models; or maybe I've jsut noticed more examples because I read more 5D threads. The latter is certainly possible.

I was doing an astronomy shoot with my 30D last year where I was coordinating lighting effects with two others using handheld walkie-talkies. I got a clear interference pattern on the shots (4 minute exposures) when I transmitted on the radios within a few feet of the camera. After that, I stepped about 15 feet away before transmitting and the interference went away. I'll dig up one of those shots and post an example.



Here it is:

hmm two threads that complain about Canon cameras, maybe I should look into Nikon exclusively. ;)

Cell phones emit quite a lot of RF too. Hold your cell near your computer when you transmit, and you can probably hear the interference in the speakers on the computer.
