Photography Question

Rebel XTI users question


This isn't exactly a problem, but I was wondering why when I capture my images in RAW mode they automatically just save to the camera instead of the CF card? On page 60-61 of our handbooks it tells how many shots can be taken given certain circumstances, but nothing about it automatically saving to your camera and whether it's safe and ok. Makes it hard to know how many you can take in RAW mode that will be correctly saved to the camera. Unless I missed it in there?

Thanks...

  Sure you're not confusing the buffer that temporarily stores pictures until it has time to put it on the card?

According to the XTi's specs it's buffer can accomodate 10 RAW images, or 27 JPG images. The camera will then lock up while it streams the contents of the buffer to the card. It will be ready for the next shot after the buffer has been cleared.

  Buffer? not sounding familier, I haven't seen anything on it in the manual. It doesn't act temporary- and I found that out by putting my CF card into the computer as normal to download, found nothing, then went back to the camera to find them all (hold onto your seat) all 318 shots were stored in RAW on my camera.. I knew it shouldn't be happening like that because the manual tells you how many should go on the card and I never received any warnings or errors telling me that had happened . . It's happened this way about 3 times with large numbers of shots .. It makes no effort to store anything RAW on my CF card.

It hasn't locked up on me either to stream...

  Okay, first the buffer is a temporary storage space that lets you keep taking pictures while the camera is writing to the card. The camera takes longer to put 10 shots on a card than it does to take 10 pictures right in a row, quick like.
Second, if your camera is really doing that, storing 318 raw shots, maybe you didn't format the card.
I haven't heard of any cameras storing their photos in the camera. Where all 318 there and viewable?

  Yes, They worked like that was the normal process. They loaded right into my Canon Raw image software and I transferred them into Photoshop..

How do you format a CF card?

  I was under the impression that the CF cards came formatted?

  I don't think your camera can store that many raw files. Coule be when you took out the CF card and upload directly to the computer, the computer cannot read the files because it's of different format. When you put the CF card back to the camera and upload to the computer via the camera using Canon's software, it recognized the raw format. The raw images were always in your CF card. The computer just need the appropriate software to read them. Of course, I could be wrong.

Also be very careful formatting the CF card. You only do it for a brand new card or after you save all the images to the computer and other media and wants to clean up the card. When you format the card, you will erase all the images stored in the card.

  I agree, that sounds a lot like what's happenin. But I thought, as W said above and as the manual indicates, that the CF card can only hold a small number of RAW images? I took 318 RAW images and they were all there..

  I don't think you're saying everything that happened.
Did you look at the pictures in the camera without the card in it?
And and what size card is it?

  No I didn't view them w/o the card, That's why I think the response before last is sounding like what I've got happening, or close to. I had assumed they were stored on the camera because when I put the card in the computer's reader they weren't showing- only Jpegs previously on the card were showing.

then once I hooked the camera up (CF card re-inserted) to download the RAW images through Canon's software they were there and happliy downloaded on the computer for me.

Its a 4GB card

  I'm just going to shoot Large-Fine from now on, I get too much saturation with RAW anyway. . .
and when looking at the image recording quality it looks like the two are the same. (10.1 million pixels) .. less pain in the butt, or fear of lost images..
