I recently got a hand me down canon EOS rebel XT, however i did not get the software disk that comes with it and when i try and plug it up to my computer it does not upload any photos or do anything at all. And yes i put it on PC connection under the menu button. So after that i downloaded an image browswer for canon which seems to do nothing as well. That led me to open up iphoto in which i saw that it was indeed connected to the canon but could not up load the photos because it says the photos are in the wrong format. Any suggestions?

also i just went to the format button on my camera, and now i cant view my pics did it erase all of them?

Yes, format erases the card. Do not do anything else. You may be able to recover the images with some software.

As far as your original question, It is best to copy your photos with a card reader. It is faster and you are assured the files will not have anything added my additional software that is handling it, such as iPhoto. That has resulted in DQ's in past challenges.

I suspect iPhoto did not recognize the photos from the Rebel because they were probably Canon's .CR2 RAW files.

Here is a roundup of data recovery software, many of them free. These should be able to recover your photos if they data has not been overwritten. I don't think any of them are Mac programs, but a PC is easy enough to find.

i use iphoto to store my photos from my panasonic camera for DPchallange, didn't realize that they add anything. What do they add? I dident know what a card reader was researched it and found one for $12. I also found Stellar photo recovery but i am having difficulty figuring out how to work it especially since i already did not know how to scan the photos from the canon on the computer, the stellar wants me to scan it to recover it but i don't know how.

Iphoto adds information to the Exif info that says it has handled it. That would make an automatic DQ if your entry got called up for validation, since it could not be confirmed the original had not been manipulated.

I'm afraid I am not familiar with the Mac software. Usually there is something in it to simply click and begin the scan and recovery.

well maybe there is an option to keep it from adding to the extension or name of file.

I don't think there is, but someone who uses a Mac as their primary computer can answer that better than I can. The sure way is to use a card reader and copy them with the file manager.

Get the card reader first, then use the recovery software. Do not use the card for anything else until you do -- you should be able to rcover the files, although none of them are likely to be "originals" for DPC validation purposes.

iPhoto (and other programs) which "download" your files often make changes to the EXIF data which we use to verify that a photo is an original. We recommend using a card reader and your computers operating system to manually drag the files from the card to your hard drive.

when it manually drags the photos does that delete it from the card or just copy it?
02/12/2011 03:42:40 PM · #11
yeah looks like im going ot have to get the card reader first because the software is not reading the camera. Thanks for the help everyone.

It will copy the files. It's just like copying any other files from one storage device to another. For example, you could also put in a USB "thumb drive" and copy the files to that.

I try to always have two copies of the file on different media. I drag the files from the camera card to my hard drive, then, when I have about 500MB accumulated, I burn those to a CD, and only then do I delete them from the camera card.

when u burn it to cd is that considered the original?
02/12/2011 08:28:12 PM · #14
As long it has not been manipulated by any image editing application that can change the exif data in the file, so yes.

You don't necessarily need a card reader, and importing files directly into iPhoto is fine. A card reader is faster (especially the Firewire versions), more convenient, and doesn't use your camera's battery power, but there's nothing inherently wrong with connecting your camera via USB cable. I have a Lumix TZ5, and it's not a problem.

If your camera is not automatically recognized by the system, then it's one of these issues (in order of likelihood):
You're running an old version of the operating system (before Leopard). Camera support is OS-level, and simply running Software Update may solve the problem.
Your iPhoto preferences aren't set to open the app when a camera is connected. It's under the "general" tab in iPhoto's preferences.
You have a bad USB cable or connection. Try another USB port, preferably not the keyboard.
For lack of a better word, your software is screwed up. In that case, an Archive & Install of the OS may be required.

The only issue with iPhoto is that if your camera is set to auto-rotate files and you shoot a JPEG in portrait orientation, the software will automatically rotate the image 'right side up' as a modified version on import. The EXIF on that file won't be a valid original, however iPhoto always saves a copy of the original and I can explain how to access it if needed.

An original is a file that is unmodified, exactly as recorded by your camera. It doesn't make any difference what media it's on. If you're using iPhoto, you really don't have much to worry about since the software protects originals in a hidden file by default.
