Boggled!

Could be simple and I'm being doltish, but I've never experienced this before. I haven't run any tests with other equipment so bear with me here. I am attempting to transfer RAW (DNG) images from my SD Card shot with a Pentax Q-S1 to my Windows PC. The files should be 4000x3000. For some reason, my PC is reading them as 1920x1440. However, if I process one of those RAW photos in camera, making no changes to file size, save as JPEG, then attempt to transfer to the PC, it comes over at 4000x3000. What the what?

Here's an example of what I mean. IMGP8023 is the DNG and IMGP8024 is the in-camera processed JPEG. I am stumped. Note, this is my laptop I use at work. If I recall, my MAC mini at home reads the DNG appropriately. Any ideas?

It looks to me as if Windows is looking at the low resolution, highly compressed JPG preview in the RAW file.

BTW, IME it is always a good idea to force the operating system to display all file extensions - e.g. .JPG, .RAW, etc.

Apart from anything else, it minimises the possibility of accidentally opening e.g. a virus, which might be named filename.pdf.exe . Some ransomware uses this tactic.

Yeah, that's so weird. I wonder if it's a card issue? But if my Mac Mini reads it fine.... I appreciate the file extensions tip. I've enabled that.

Reading what someone wrote to my question in a different forum, I plugged in the SD card, started Photoshop Express, then navigated to, and opened, a RAW file from the SD card. It opened at full resolution.

I have always thought Windows File Explorer would list, and allow transfer of, all files in any given storage drive, regardless of whether Windows could actually natively read them - to allow for Windows compatible programs that can (Photoshop for latest camera body raw files, for example). There must be a setting in FE I'm missing.

WFE can only display what the file hands it. It will copy/transfer anything, even files that it cannot read. It's not a WFE problem, it's an operator problem ... 😉 .

Try opening the file in a "proper" program that can read the native file - e.g. DxO, Lightroom, Photoshop, FastStone Viewer, PIE Studio or similar.

IMO, using WFE to upload files from a card to your computer is not the best way to do this. You should ingest files using a program that knows how to do this properly - e.g. as above.
