5D Mark IV raw files not keeping the original size

flogarzoli — Thu, 05 May 2022 13:04:26 GMT

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?

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.

Thank you. I am using a Mac OS Monterey 12.3.1 and Photoshop CC v 23.3.1.

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.

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.

I am not really sure whether Adobe assigns the arbitrary 72 DPI or Canon does. I use Photoshop/Lightroom 95% of the time so I don't know how other editors interpet. The bottom line is all photos you shoot from your camera are at full resolution and in Raw format. DPI is a printer spec it has nothing to do with your camera photos. The only thing that matters is the number of pixels.

Let's say you have a photo that is 800 x 1000 pixels. Now you print that photo to 8″×10″. You now have 100 DPI. 800 pixels divided by 8 inches equals 100 DPI. You now print a 24″×30″ so it is now 33 DPI. But the number pixels don’t change. DPI does not matter for your photos.

I figured it out! There is a checkbox that was marked in camera raw preferences that when you opened the file it would reduce it automatically. I didn’t know that was active I will send screenshots.

Good job figuring it out.

Would you please show me what you did? I'm having the same problem. I don't know where camera raw preferences are located... Thanks.

Yes, I'm having the same issue. I use Lightroom Classic, where is the checkbox to make sure it doesn't change. My clients keep saying they have low res images and I can't fix it. Thanks.

It is in the "Export" function.
