DNGs upside-down

Hi guys,

I got my 645z last week and spend every minute I can spare familiarizing myself with it. So far, I love it, appart from a few kinks. One of those is the fact that all images I shoot appear upside down, when I copy them to my computer. There IS a feature in the menu that is called something like auto-rotate images. But then images appear fine on the computer, but are upside-down on the screen of the camera. Any ideas, what I might be doing wrong?

You didn't buy one that was destined exclusively for use in the Australian market did you?

Is it just with the DNG or it it across all the formats - PEF and JPG also? If you rotate the camera 180 degrees, does the rear monitor follow suit? If so, I would think that the camera does not know what orientation/direction is really up (although I like Kerrowdown's observation). There should be an internal sensor that detects orientation that may be a bit confused (usually detecting portrait or landscape orientation) - defective. I would contact Pentax about it.

That really sounds like the orientation sensor was installed incorrectly possibly right on the board

What software are you using on your computer?

If it's only DNG and not jpeg, it probably isn't the orientation sensor.

If you post an example file, I can test if it works in Australia.

Try taking an image with the camera upside down to test what orientation it has.

Does the same to me. And I have seen a few other reports of this problem. So don't think it is a hardware problem, but a software one. I have only tried Lightroom, so could be Lightroom miss reading the data or the data is being written wrong to the file. This is on DNG, PEF and JPEG

It would be interesting to also check the liveview level sensor (along with the ball level sensor - I don't know any other description - but its another screen other than on live view) and see what it reports. In particular the movement side to side and tipping up and down. Also, turn the camera upside down and do the same level checks and see how it responds.

I'll also bet dollars to donuts that there is a debug mode where this can be corrected in some configuration setup.

Just a thought.....

Hi everyone, thank you all so much for your suggestions. I found the problem. Under Menu - Image Capture Settings: There is the checkbox: 180 degree rotation info. This needs to be unchecked, no matter if DNG or PEF is the raw format. Seeing it rotated correctly in-camera I thought, that this feature would rightfully have to be checked.
My compliments to the author of the Australia joke by the way, made my day .

Cheers, John
