5D Mark IV raw files not keeping the original size


I have a 5D Mark IV, and selected RAW image quality 6720x4480, no JPG only RAW. However, when I download the photos to my computer, the image size obtained is always 1344x2016 300dpi resolution. This did not happen before, I used to see the images in the selected size. I did not make any changes to my camera, computer or software. Thank you for your help!



Welcome to the forum.

What software are you using? What operating system? Can you post a screenshot of display that shows the info?

What is the file size shown in the folder where the image is located?

Thank you. I am using a Mac OS Monterey 12.3.1 and Photoshop CC v 23.3.1. Screen Shot 2022-05-05 at 5.33.05 PM.pngScreen Shot 2022-05-05 at 5.31.38 PM.pngIMG_1637.JPG

It looks like there is some sort of resizing going on.

Not sure what software is showing, but the image size in the software is ~1300 pixels, compatible with the Image Size window at 1344.

What software is it? Edit - Just saw it was Ps. Let me try a file on my MacBook.

Have you cropped the image? Maybe inadvertently turned on cropping in camera?

I can get a display similar to yours when I crop the image in Ps.

I did not crop the picture, that is the original CR2 and I am viewing it in photoshop CC in my Mac. This is happening with every single CR2 I open. I can't figure out what is wrong.

Try resetting Photoshop preferences:

Also, you could download Canon Digital Photo Professional from the Canon support site and see how DPP opens the files (to see if it is a Ps problem).

Also, if you post that RAW file on Dropbox or One Drive I will open it and see if I can figure out what is happening.

Thank you. I will give it a try 


300 dpi is just a red herring. I believe that Canon usually uses 72 dpi, but it really does not matter, especially for a RAW.

It sounds like you are just getting the embedded preview, not the raw file.


Actually there is a placeholder for a number. Canon fills it with 72. It is meaningless. No matter what file size or format you select in your camera, large raw, to small jpg or anywhere in between, the camera captures at full resolution. Every shot is made at full res! It is when you tell the camera how you want it saved that something happens. 

When you copy or u/l to your computer you are using that saved file. It is transferred at that exact size. The only place any size change can happen is in your photo viewer or photo editor software. And, that is unlikely.

I never knew a RAW file could have DPI in its EXIF.  Maybe I have never noticed it.  If RAW and JPG files use the same EXIF format, I suppose a RAW file could have a DPI field.
