After becoming a full-fledged time-nut (I’m compiling a new Linux kernel on my second NTP server as we speak), I have started to use the statistics that I usually install on a server just to keep a check on it. Sure, when installing something like MRTG, it’s great to see if something is clogging the system, but mostly, it’s unused. But when working with an NTP server a lot of factors start to make a difference. The temperature of the processor (the whole computer actually, mostly due to crystal drift), the load of the CPU’s, etc.
To be able to tag your DSLR pictures with GPS information is both fun and practical. But to date, most DSLR cameras don’t have GPS built-in or is an expensive hardware add-on option. That includes the Wi-Fi iPad you might own. The last couple of years I’ve used a lot of different solutions to track GPS data while I’m out taking photographs. My first way was to use a Garmin GPS unit and then transfer the information to my Mac, but now, with mobile phones like iPhone and Android, there’s no reason to tug along yet another device.
My weapon of choice now is an app for iPhone and iPad called GeoTagr, a universal app for logging GPS tracks while you photograph, and then tag images with location data. For me, the pictures I want to tag are the RAW images that I import into Adobe Lightroom 4. And with this app, it’s straightforward to accomplish.
Geotag DSLR images using an iPhone and a Mac
One of the nice things about modern camera phones and even some regular cameras uses GPS to tag photos and embed the coordinates in the pictures EXIF data. But wouldn’t it be great if you could do that with your fancy DSLR camera photos as well? Programs like iPhoto, Aperture and Adobe Lightroom 4 can show you your pictures on a map. Many online photo sites like Flickr also uses the GPS data in the pictures to display them on a map.
