Topic: Lumia 1520 high-res no gps in EXIF

Ok, this is not the direct responsibility of the Photosynth team, but it is all Microsoft now. But maybe the Team has an internal shortcut. It is on WP8 Black, I have no WP8.1 Cyan yet. I have my Nokia Camera app setting to create both normal and high-res versions. (One cannot have high-res only.) The normal resolution does have gps co-ordinates in EXIF, but high-res doesn't. I find this utter stupidity. Especially since Lumia was not storing gps and I complained about it.

Smartphones are sensor rich devices and none of my Lumia 710, 920, 1520 devices stores picture heading in EXIF, while my stupid Nexus 7 does.

I would really love to see Microsoft consolidate its imaging products and move create a good seamless user experience. At this moment it is neither good nor seamless.

Of course I will try to give feedback to Nokia as well.

A couple of quick questions, Joscelin: 

1) By "picture heading in EXIF" are you referring to the camera's compass bearing at time of capture?

2) How do the filenames of the full resolution photos from a Lumia 1020, 1520, Icon, or 930 compare to the 5 megapixel versions?
Could you post an example filename list of the full res and low res copies for 10 photos as they come off the phone?

Christoph pointed me to ExifTool last month and it appears from this reply that it can be used to copy the full EXIF info from one file to another, but I don't know how to set up a batch script to correctly fetch the filenames of the different resolution files (so that they line up) and fix an entire set at once.

Christoph, if you're reading this, could you help us poor GUI-bound users out by telling us what the script should look like or just pointing us to a tool that could do this that has a GUI? My searches aren't turning much up.

1. "picture heading in EXIF" = "camera's compass bearing at time of capture". And why not record roll and tilt as well.

2. I am puzzled as to why you ask this. But, I'll get back to this and the rest later, as it is close to 2 am and need to get up at 6 am again.

Hi Nate, getting back to 2.
I cannot tell for other than the Lumia 1520.
File names have a standardized date-time stamp format.
Low res: WP_YYYYMMDD_HH_MM_SS_Pro.jpg
High res: WP_YYYYMMDD_HH_MM_SS_Pro__highres.jpg

Still curious as to why you are asking for this.

As for editing and adding EXIF data.

As far as I can recall Microsoft Pro Photo Tools has an issue with mapping gps co-ordinates, just like Photosynth 1.

On ExifTool. This seems to be the defacto tool. Also for professionals.
I am using it for several years now with the gui front end GeoSetter, which uses Google Maps.

It is easy with GeoSetter to get the gps data from the low res and put them to the according high-res for a set at the same spot. So, this gets more laborious for walks and walls, unless one uses a ExifTool with a script, which is not really my piece of cake, although I did it once.

I would definitely very much appreciate it, if Bing Maps Photosynth would provide a server based service for EXIF editing of photos on OneDrive with web, win8 and WP8 front end apps.

But, the better news is... Having updated my Lumia 1520 to Windows Phone 8.1 with Nokia Cyan firmware last night, I am happy to say that gps co-ordinates are recorded in EXIF of high-res now.

:-( focal length is still not stored in both low and high-res.
Neither is the compass heading. And this is Microsoft Nokia Lumia.

Sorry, I thought I made it clear above why I was asking for the difference in filename between low and high res.

I wanted to figure out a workflow that would allow you (or anyone) to copy and paste the entire EXIF metadata from all of the low res photos and paste it onto their high res counterpart.

That necessitates some reliable way of ensuring that I can correctly pair a particular low res image with its high res version, so that no errors are made, copying metadata fields onto the wrong photo.

I would have liked to have owned the 1020 and the Icon as soon as they came out, however I simply don't have the money for such things so I needed someone who owned a Lumia with a high res sensor that produced two resolutions to tell me how the filenames differed.

Re: Pro Photo Tools, it has a number of useful tools which work adequately but it doesn't have wholesale EXIF copy and paste from one batch of photos to a duplicate set.

Again, I'm not advocating Pro Photo Tools 2 for the task at hand, but since you brought up its mapping precision, here's what you said about it a few years ago:

:-) You must have quite a proprietary reference database Nate. Yes, I do recall all the confusion I ran into on this subject. The sure thing is that Photosynth 1 or the Bing Maps API it uses has a bug that never got resolved. There is something in the back of my mind that there is an issue with Pro Photo Tools too. But, never mind GeoSetter is a lot more powerful than Pro Photo Tools.


What definitely does amaze me while having sensor rich devices nowadays, is not putting all the info in EXIF. E.g. compass bearing, height, tilt and roll.
