Sony A7 IV D- Range Optimizer

Should I leave this on or off? I shoot raw and jpeg. If I understand, it does not impact the raw files but I'm not sure. What about movie mode? Trying to understand the setting and the impacts. Any help is appreciated.

I leave mine off, but I only shoot RAW. It won't show any in camera effects on RAW images, so no point. Different if you shoot and use JPEG

I leave it off as I save to both Cards, one RAW + heif. I think It has no effect, unless you don’t save to raw.

I was just going to post something about HEIF. What kind of decoder are you using? Do you see a tangible difference between HEIF and jpeg? It is supposed to be lossless compressed with more information in a smaller file and might be a good alternative for those who want to produce an in-camera processed image. There isn't much real-world use going on, would love to hear how you use/view/etc.

Only had my camera since Nov and since Jan I’m just downloading and archiving in that format. It’s a native Mac format so it behaves like jpeg on my Apple devices and iMac using any app.

All the images I took in Nov/Dec were heif while I was on a trip to Czech Republic. These respond very well to editing in luminar neo, and display upon transfer based on the camera setting photo profile. I use V V.

The Sony imaging app provides limited support for the format removing most of the editing options based on its identification of the heif files as jpeg.

Worth a fiddle. The heif files are all 33Mb -same as the RAW file size from A7iv. I’ll see if it is lossless.
