Remember when Adobe screwed up the Import dialogue bc they thought we were too stupid to use all that flexibility? Blame it on the millennials. Of course, I don't even know what generation I am. Pre-war? (your WWII -- The big one) Perhaps geezer? Maybe they will add emojis to their ratings?

My M3 (single stroke) is still my favorite camera to use but I can't remember where the memory card goes?

White balance is a poster child for RAW. Really there is no "correct" white balance. And it is a good learning tool. Take almost any photo without really familiar colors (Like Kodak yellow if you remember that) and drag the white balance slider around to discover different interpretations. Sort of a fun learning experience. Works for exposure also. If you need it smack on take a shot with your Colorchecker target included and make a camera calibration.

RAW vs JPEG should be added to the list of things not debated in polite company: religion, politics, truck brands, Canon/Nikon... Fortunately this is a place for debating some of these! I have come to only shoot RAW at least in part because I use Lightroom to organize all of my images so only see the undeniable improvement in editability. But that is just me. If color accuracy is of primary importance (scientific or advertising photography) you would use only RAW. (Helpful tip: Photograph the rare butterfly BEFORE placing your Passport Colorchecker on it!) Likewise, if you do volume studio photography where the lighting is well controlled you would pump out those perfect JPEGS. I have a hard time conjuring up a situation where I would would want to save both. But again that is just me. But then I don't do social media. I liken posting my best work like painting the Mona Lisa on the side of a pickup. Oh, I have read that National Geographic requires their photographers to submit the RAW files with their finished produce to maintain the integrity of the image. No Fauxshop cutting and pasting.

From the perspective of a retired engineer it is pretty simple-- If the camera/lens is mounted on a rock solid tripod then anything VR does is wrong so turn it off so it can't do anything. On the other hand if you fail to turn it on when removing from the tripod you lose something. My policy is to reset my camera to a ready to go state when stowing it. Do I do that? Rarely! Some have speculated that's it saves batteries but unless you are waiting for the volcano to erupt (in which case it should be on because the earth moves) the power drawn is minimal compared to that consumed actually taking a picture.

Bottom line it probably doesn't matter which is why we can't remember the reason.
