My Pentax K5ii can use its sensor shift capability to rotate the sensor to level the horizon, I also get a 2 axis level readout in the viewfinder or on the rear display. Some cameras do have the capability you describe.


My Nikon D800 had a digital artificial horizon, so yes some cameras do have this. However, rotating images in software is absolutely a last resort as it can lead to odd moire effects and you will lose some of the periphery of the image. Of course rotating images when using film photography at the print stage doesn't suffer from optical issues. As is the ...


You can use exiftool to remove the orientation tag: exiftool -Orientation= /target/dir/or/File Replace /target/dir/or/File with the files and/or directories you want to process. If run under Unix/Mac, use single quotes to avoid bash interpretation. To suppress the creation of backup files, add -overwrite_original. To recurse into subdirectories, add -r.


My Canon DSLR has an electronic leveller that I can enable on the LCD screen when composing an image. I'm not sure if that data gets written to the exif data of the file or not. I'm not sure if this is a mid/high end feature but it's not a new feature; it's in my 6D which was released in 2012. Software applications like Photoshop and Lightroom and probably ...


there is always the grueling task of orienting them correctly so that the horizon looks straight Setting the camera level doesn't necessarily make the "horizon" look straight. It works when the background is an ocean or a vast plain, but it's not uncommon to have a mountain or hill or the far shore of a lake in the background. Those may not technically be a ...


Let me start out by saying I'm an engineer not a photographer, the kinds of cameras I work with cost in the tens of millions to hundreds of millions of dollars, but I think for the purposes of this questions I might be able to help. Often "a sensor" is cheap, but "a sensor that is accurate enough, and provides the right information" is incredibly expensive....


Correcting an arbitrary rotation in post processing always means significant resolution loss and/or computational effort - unlike correcting 90° where you just swap the axes (and maybe even do so before compressing the image for storage - algorithms like JPEG are not totally agnostic of lines vs columns). It is likely that a manufacturer would not only have ...


Do all three by adding a “remember my choice” check box Boolean to the dialogue of the second option.


The answer of @bob-macaroni-mcstevens is wise, and a certain degree of editing before uploading is something I am considering adding to the features roadmap. However, I have discovered the problem, and I am answering my own question as it could be helpful to someone else. The orientation of an image is generally stored in the EXIF metadata contained within ...


In fact the mentioned exiftool command did not work for me. It rewrote the metadata, but did not remove the Orientation tag. I finally found this solution: exiftool -n -Orientation=0 /path/to/my/file


The format you choose is ultimately down to your personal preference. However, there are basic, and fairly obvious, design principles you can follow. If the vast majority of your images are "landscape", then choose a format that reflects that. The same is true if the majority of your images are "portrait". You then have to decide how to best fit in the non-...


Either that or Lightroom is writing the images rotated in the correct orientation, but leaving the EXIF tags in place, causing software to rotate it wrong. I would check what LR is writing using EXIFTool, and depending on what you see, look for options you can change in Lightroom to turn on or off exporting of whichever EXIF tags are at issue.


Unfortunately, the only way to know for sure whether a digital picture frame will automatically rotate images for you is to try it. To avoid problems, you can rotate your images prior to copying them to the frame for display. exiftran can losslessly rotate images based on the Exif orientation tag: exiftran -abip *.jpg jhead also uses the Exif orientation ...
