I think it is safe to say cRAW shows a negligible decrease in quality.

This compressed raw file will enable you to save even more images on one memory card without loss of quality.

It is a variation of the regular raw file format, but its about half the file size.

Using this compressed cRAW file format, you can store about twice as much images on your memory card.

This can be very handy, especially for the large files of the Canon EOS R5.

For the Canon EOS R6, it might be less important, because the sensor has only 20 megapixels, producing files that are between 20 MB and 30 MB.

With the cRAW file format, you end up with files between 10 MB and 16 MB.

I not only wanted to see if there was a difference between ISO levels, but also by correcting underexposure, overexposure, and with extreme post-processing.

In order to have a highlight in the setup, I placed a LED underneath one oak leaf.

I used the manual exposure setting and manual focus, although the latter is of lesser importance for this test.

It would be great if Canon allowed saving a raw to one card and cRAW for backup to the other one.

I decided to shoot a series of images ranging from ISO 100 up to ISO 102,400.

I dont want to bother you with the whole series; thus, I chose to compare only the ISO 100 and ISO 1,600 images next to each other.

Even with a large magnification, which resembles approximately 100, the images from the compressed raw show no visible decrease in quality.

This has been corrected in Lightroom Classic by increasing the exposure slider to resemble a correct exposure.

I did this with both the ISO 100 and the ISO 1,600 images to see if this exposure correction had an effect on the quality of the cRAW file compared to the raw file.

As you can see, the leave that is lit by the LED light is clipped.

Lets have a look at the result, both at ISO 100 and ISO 1,600.

For this comparison, I took the images that had a three-stop underexposure and corrected this in Lightroom Classic again.

Besides that, I set the shadows to 100 and the highlights to -100.

I also changed the black point and white point and increased texture, clarity, dehaze, and vibrance.

Perhaps a closer look will show some difference, especially if something like a color checker is photographed.
