M10 GPS with smartphone?

Does anyone know if it's possible to GPS tag images by using a smartphone's GPS? In theory it should be:

M10 connected to iphone via Bluetooth

iPhone sends GPS info to M10

M10 adds this to the exif of each image

 

I bought the EVF solely for GPS; but now I'm thinking of returning it, because it blocks the shutter dial partially, and just isn't in line with how a rangefinder is supposed to be used (and I would never use the EVF), in my opinion.

 

But connecting through a smartphone makes sense and is far more elegant.

With iPhone: gps4cam. I use the Pro version and export the gpx; later import them in Lightroom.

 

I use this sometimes when I don't use the evf. But mostly I use the evf for gps.

I use, gps4cam as well. You dont need to export as gpx, you take a photo of QR code at the end of your trip adn run it through the app on your computer. It automatically adds time and gps info to the exif. You can use this setup with multiple cameras, with each camera you need to take a picture of the QR code.

 

Gps4cam with iOS10 has a small bug on iphone6 and iphone7+. After you start the recording, you need to quit the app and restart again to make the screen work, otherwose you cant hit any button. Thats all.

 

Cheers,

I haven't been able to use gps4cam with wide angle (28mm) or my Noctilux, for the same reason: you can't get close enough to fill the frame of the image with the QR code. Anyone else tried gps4Cam with these types of lenses and been successful?

I use it with 50 and 35 without any problem, I don't think you need to fill the frame. The program finds the picture with the code and analyze it without any problem in my case.

The problem with the 50mm Nocti is that the min focus distance is about 1 meter.  GPS4CAM doesn't work at that distance, at least not when I tried it (once).

With the 28mm, also didn't work - the QR code was just too small relative to the overall size of the image.

 

Can someone who uses their iPhone to record time stamps explain how they merge this data into the exif image data in LR?

 

Thanks

Before you start recording be sure that your camera-time is the same as in your iPhone. With gpx-export this is important! If you use QR-code not really (then the software will correct this; in LR it's not really possible directly...)

 

Export gpx-file 

Import your pictures in LR

 

In "maps" you can load a tracklog (your gpx-file)

mark all your pictures

"tag your pictures"

 

I'm not sure if this is all the same in english-verison. I could show some pictures - but I only have the german version of LR. So are some words are different.

I use an app called GeoTagr. It can upload the gps tracks from iPhone to Dropbox (needs an authentication the first time). From Lightroom I locate the gpx file in my Mac's Dropbox folder (and it remembers the placement the next time). This is a very handy way to transfer the files.

 

If you make several gps recordings in different places before you geotag the images, you can upload all at once in an overall gpx file, and geotag all at once in Lightroom.

Isn't it a simple solution to use a longer/closer-focusing lens? After all, you only need to photograph the code before you start your trip.

I can heartily recommend GeoTag Pro to add GPS data to your Leica photos. It has a phone app and a desktop app. When you start the app it continuously tracks your movements. When you sync that file us with a folder of photos it looks at the time data in each photograph and matches it us with your location log. The EXIF data is updated and now your photos have GPS coordinates - simples!

I use it with 50 Cron and Lux without any issues. You don't need to fill the frame, just a clear picture in a reasonable size.

I am thrilled that such a solution exists.

 

Just 2 questions:

 

1) I presume that you have to photograph the QR code at the beginning and at the end of your trip. Is this correct?

2) Which so,ution do you recommend? Two are mentionned here. Which one is simpler in conjunction with Lightroom on a Mac?

It's much simpler than that actually.

 

At the beginning of the trip, you run the app, it needs to be keep running at the background. End of the trip, you stop recording. It will create a QR code. You take a photo of the code, put the card into the computer, run the gps4cam app for mac or windows. It will read the QR, get the GPS data plus time of the stamp, write it on the DNG.

 

The beauty of this is, it works through different time zones, you don't need to sync the clock of the phone with the camera and you can use 1 phone to record GPS data for unlimited number of cameras. What you need to do is, to take the picture of the QR code with each camera, if you have more than 1.

I do not have the app, but the Lite version description states that lite has all the pro features, but captures only during the first 30 minutes of each trip.

Thank you very much. I did not read that far. But in that case the no-cost version does make less sense (to me anyway). I will try it out soon.

With gps4cam, you definitely need to sync your camera clock with your iphone clock. That’s how it tags each image.

 

That’s not really a big deal. What is a big deal is that with a wide angle lens, even with a 28mm, it doesn’t work. The QR code is too small. I suppose if you crop it and then resave and use the cropped image...but now the timestamp is wrong, so you have to change the time of the cropped image to match when the original was taken.
