On one day’s shots with my Canon 70D, something occurred which I have not seen before or since. Shooting with auto (RAW + JPG) and having made no changes to anything of which I’m aware, the size of the CR2 pictures is 5472 x 3648 while the JPG size is 5472 x 3072, being cropped at the top and bottom. What could have caused this? With my Canon G16, both always have been 4000 x 3000.

For the Sony and Nikon and all other camera types definition of CR2 : "A file with the CR2 file extension is a Canon Raw Version 2 image file created by a Canon digital camera. CR2 files are based on the TIFF file specification, so they're usually high quality, uncompressed, and large."

I'm not familiar with that camera, but you probably have Menu choices for the quality/size/resolution of the image. Take a look and see how they're set. As for them changing on their own, strange things have been known to happen. : )

You may have inadvertently changed the aspect from 3:2 to 16:9.

Not sure this has anything to do with the question . . .

Thanks for the responses - perhaps I can explain this a little more clearly. I took a number of pictures with my Canon 70D, set on automatic, RAW + JPG – and with nothing changed from a previous shoot. After finishing, I downloaded the resultant files from the camera to my computer, using the Canon EOS transfer utility. The result – always - is two files for each picture, one CR2 and one JPG. On all previous occasions, and one since, the files, whether CR2 or JPG, have been 5472 x 3648 with that camera. This time the CR2 and JPG files were different sizes from each other, as noted. I know what a CR2 file is, and I didn’t change the aspect ratio at which I took the pictures – I never do. Had I done so I would have expected both the CR2 and JPG files still to be equivalent in size.

There was no processing involved, just downloading from camera to computer, then viewing with Irfanview – as usual.

Wouldn't the cr2 and jpg have the same aspect? With my mirrorless cameras they are.

Can you double-check that with a test?

Check what??? I can see the difference in size on the file list pictures, and the dimensions are shown on Irfanview as well as on the EXIF!!! The CR2 and JPG sizes always have been the same! (and are, again – with my having done nothing to make any change).

Just for further information, I just now did a quick save – with no processing – from the CR2 file to a “same as original size” jpg file in Adobe Photoshop Express. It is 5472 x 3648, the same as the original CR2 file out of the camera. The JPG file – directly out of the camera was 5472 x 3072. The ONLY processing involved was that which always is done by the camera in order to produce a JPG file, for RAW + JPG.

Yes, that is what I was asking to clarify - have they been the same in the past.

I understand your frustrations, but there are a sizable number of topics posted where the issue turned out to be something the OP changed without being aware. Hope the answer is offered or discovered soon.

Have you always used Adobe Photoshop Express? If so, could you have accidently changed something in the software? Have you tried opening the files using a different program? It might not be the camera.

AGAIN - DIRECTLY from the camera to the computer. I don't even have to use ANY software in order to see the difference. You can tell the file characteristics without ever opening it in a processing program or a viewer. I just saved (one time only) from CR2 to JPG using Photoshop Express because it was the quickest way to see what happened.

The only change would have been on the camera. I only turned it on and clicked the shutter. When finished, I turned it off. The next day, I turned it on and clicked the shutter. I would anticipate no changes having been made thereby.

Taking a second look at Gene's answer with calculator in hand, the numbers prove his point. So, either the OP changed something, somebody snuck into his room and changed something, or it has always been this way and he never noticed.

If the camera is doing the while exporting this images, maybe using a card reader instead of directly connecting the camera will make a difference.
