I was a third shooter at my daughters wedding and always shoot in raw. Even slot II is duplicate in Raw. My camera was unattended at times during setup and somewhere between decorating tables and before the first look and formal shots my cards went from Raw to jpg. Is there any way of switching without going into the menu? Was it a semi sabotage from a photographer "friend"? Has this happened to anyone else?

If you accidentally press the QUAL button instead of the ISO button and turn the dial, it can change the camera from RAW to jpg or tiff.

If you're pretty sure you didn't do it, then perhaps someone picked up your camera and was playing with the buttons and dials.

I thought success was a result of buying a full frame, mirrorless camera. After all, you taught me everything I know.

Look at the supposition of the OP: the human did nothing wrong, the equipment failed. And yet, some group of humans decided to place a very dangerous button on the body exterior. A danger encountered regularly in the daily discussions of the community. You seemed to have missed the lesson on the importance of the brand of mirrorless full-frame digital camera and how that correlates to success.

Your body assuming room temperature usually brings learning to a halt.

Anything is possible like that. I never leave my cameras laying around where someone could handle them. And certainly not at a wedding or party with strangers. I don't really shoot those sorts of projects these days anyway. Never much did since I am a hobbyist.

No idea about your specific camera but all my Digital Pentax cameras have a programmable button or two. The factory default for one is RAW>JPG - JPG>RAW. But even that is only for one exposure then it reverts to the menu selected file format and quality. I have reprogrammed the button to something else. There may be buttons with programmable functions on your D750 that persist for an entire session until you change the setting back intentionally. Check your manual or yes, someone here may know. Hopefully you got good JPGs. Good luck.

My camera goes from Program to AUTO sometimes all by itself. At least, that’s the way it seems. At times my fingers do their own walking.

I understand what you're saying in your cryptic way. That scares me.

THANK YOU! That was probably it. I was adjusting ISO with my fat fingers around that time as I had just stepped outside. Luckily I still got the images I needed.

YES, that makes sense. I just stepped outside and was adjusting ISO while walking....

You're welcome. By the way, I've used two Nikon DSLRS. My D810 had the QUAL and ISO buttons on the left. My D850 has the ISO button on the right, just in front of the little LCD screen on top of the camera. You can adjust the ISO with two fingers of the same hand.

The OP may have been a victim of the Law of the Perversity of Inanimate Objects.

Rather than quote the law (I'm not sure it's written down anywhere), I'll give a simple example. You have a bunch of cables (audio, HDMI, various flavors of USB, etc.) that you don't need immediately. You find a box or drawer and carefully place each one, neatly coiled, in storage. The next time you go to use one, you find that they are all tangled up with each other, and each individual cable has several kinks. How did this happen? Blame the Law of the Perversity of Inanimate Objects.

Keep the camera in your hands only.
