weird artifact with 24-70ii/6D

Awhile back, my friend shot an image that resulted in this artifact.

Heya,

Time for a new SD card.

Very best,

That is a corrupted image file. Could be a faulty card, a faulty connection when downloading to the computer (cable, card reader etc.) a random glitch in camera or other possibilities. I had a single corrupt image shortly after getting my 5D3 three years ago, didn't recur for two years then I got one more, nothing since. That is 2 occurences in around 60,000 clicks so I don't worry about it.

If it happens more frequently you need to start ruling out causes. First check the image on the card in the camera, if that doesn't show the corruption then the problem is probably going to be somewhere in your downloading or computer, so try a different lead or card reader and redownload the set of images where the corruption showed up.

On the other hand, corruption showing up on the camera display, reading the original file on the card, has occured prior to download so is going to be a fault in the card or possibly the camera. So try a different card.

It comes down to trial and error to locate where the corruption is taking place.

I had something a bit like this on my 500d. Once, and it never happened again! Some form of corruption.

I used a brand new card reader that did that to a bunch of my photographs. It was the first time I ever used a card reader to transfer files to my computer instead of plugging the camera into the computer with the USB cable.

As stated above . . . it is mostly like the card, the reader, or the cable. The camera itself is probably just fine.
