Yes
I think I probably know the answer to this question, but I just wanted a second opinion ...

I was taking pics today with the camera set up to save as raw and jpeg. I was shooting a bungee jump and had the camera set to continuous shoot. Firstly, I wasn't getting the normal fps and secondly, when I looked at the pics, some of the jpegs have lines down them, like they haven't written properly.

I'm thinking this is all down to the extra time it takes to write raw files... would I be right?
 
if you're saving in raw and jpg there is more information to be saved, so the cameras buffer fills quicker and the longer it takes to write to the card. Faster cards come in useful here...
 
Hiya
got to disagree with your analysis there old chap, the only time I've had images with lines on them it was the CF card on it's last legs corrupting the images. :'(

anyone else got a third opinion? :thinking:

The card is a Sandisk Ultra... the banding doesn't appear on the Raw files

I would doubt from what you said that it is the memory card ie ok on RAW but you can check the card out. Stick it in the computer and read/write test it there. Alternatively can you borrow a card off someone else or try your card in another camera.

Why are you shooting RAW+JPG anyway? Does your software not allow you to create the JPG from the RAW as it transfers them to your computer?

Erm, that was a mistake! I had a very traumatic experience. My partner had given me all her jewellery - including her engagement ring - in preparation for doing the jump. And I kind of lost the ring! I was in something of a panic, to say the least, sorting through my camera bag and all my pockets, wondering if I had time to retrace my steps before she was hoisted up in the crane. An old man standing close by must have noticed my panic and pointed to something on the ground ... about 8inches from the edge of the harbour wall was the ring! If it had rolled, it would have been on the rocks below and I would have been dead meat!!

By the time I picked it up and put it somewhere safe, she was getting in the cage to be hoisted up and instead of setting the camera on raw, I put it on raw and jpeg!! In the grand scheme of things, it seemed a minor error!!!!
 
better a messed up card than a lost ring!!!!!!!!!!!!!!

save all the pics then format the card and tart over see what happens then
 
Ah Ha! I've had this before.

Canon 400D

Shot a burst of raw files and then switched the camera off before the camera had finished writing the files to the card.
It sometimes takes a while to transfer the files for some reason, dunno, outside temp maybe?

I tried it again and the same thing happened. Now that I'm aware of it I now wait until the red transfer light stops flashing.
