Few months ago I bought a Canon EOS 250D and after I took some shoots , some of them are unable to open with any program and when I puted the SD card back into the camera was the same ...
Somebody can help me please ?
If you can clarify a couple points I may be able to help:
Do some photos on the SD card open correctly but some don't? or
Do NONE of the pictures on the SD card open correctly?
When you say the files could not be opened with any program, can you tell me what programs you tried to open the files with?
Can you tell me what the file extension is for the files that wouldn't open? Are they like "photo1.jpg" or "photo1.DNG" or something else?
When you put the SD card back in the camera, are you able to see all the photos on the camera's view screen?
