Canon 6D shooting in RAW only and using the Canon Camera Connect software on an Android phone. I saved some photos to the phone like i always do so I can show people their images, etc. so i know i had the images. But when i downloaded the photos i noticed some, including the ones i downloaded on the phone were not on the card. By the image numbers its missing like 50 files! YIKES!! i 2x checked the card, since i havent formatted it yet, and there are 50 files missing, and you can tell by the time date theres a half hour missing. I knew i had them on the card originally since i downloaded some onto the phone. I do remember changing cards as i was asked to do video once i got there but it was too dark, and i wasnt hired to do video anyway. I checked the other cards i have and no luck.

Could a card drop files? If i didnt have them on my phone it would not be such a mystery, but i know i had them originally.

have an important job this weekend so i am not using that card, and hope its not a camera issue...
thought appreciated.
thanks!

If you reinsert the card into the camera body, can you see the images that you think are missing? Also, what brand/model card? Many card manufacturers have card specific recovery software. Often the recovery software is free but you likely need an "activation" code that came with the card. That is the case for Lexar's Image Rescue software (http://www.lexar.fr/im​agerescue (external link)). Sandisk's RescuePro can be found at http://www.lc-tech.com ...pro-and-rescuepro-deluxe/ (external link).

There is also something called Recuva (http://www.piriform.co​m/recuva (external link)) that some people use.

i had the same happen with my 6D. In fact, maybe I'm dreaming, but it seems like I saw someone else post about it too.

I downloaded Image Rescue 5 and was able to locate and pull all the missing files off of the card.

I had 99 or a hundred missing files, but, to the best of my recollection, had not been messing with my iPhone before doing it.

edit: actually, it looks like i pulled 111 files off the bad card and the time stamps show they were shot within an hour (mostly 5 shot brackets) one morning.

i stopped using that card too, and haven't noticed anything like that since.

fOUND THE PROBLEM! i put the card i switched to back in the camera and the images were on another card, BUT they did not show up in Windows Explorer until i sorted for date. There were other images on the card from an earlier date and initially Windows File Ex. only showed images from the previous date. I dont really know why they wouldnt show up in File Explorer until i sorted them for date, seems like they would have shown up without doing that. At least i know nothing is wrong with the camera or the cards.... NOw if i can only get that 600 ex rt to fire 100% of the time LOL!!

Glad it was sorted out. But a question, actually a few. Where you trying to view jpeg's or RAW and were you looking for file names, icons, or thumbnails?

Do you have the Microsoft Codec for the 6D installed? See https://www.microsoft.​com ...oad/details.aspx?id​=26829 (external link).

Not sure you understand since you use the word "effect". If you go to the link I provided the basics are explained.

The Microsoft Camera Codec Pack enables the viewing of a variety of device-specific file formats.


Codec is an extraction from "code" and "decode". Basically as a new camera is brought to market, the camera maker may possibly change the format of the image, very often the RAW format. The Microsoft Codec provides the tools for your Windows based PC to properly see the image. The alternative is to use the camera maker provide software, Digital Photo Professional for instance in the case of Canon.

JPEG images rarely give problems since the JPEG format has been well defined for many years and remains relatively unchanged.
