A tourist, Tim Viltz, travelling through Ireland shows us just how beautiful our country is in this video created from drone footage shot by a Phantom 4. I don’t recognise most of the locations though. Only one way to fix that, travel!

Spots at f/22
It might be time to clean the sensor of my camera again. The circles in the photo above are the spots I removed in Lightroom. They’re caused by little specks of dirt or dust on the camera sensor.
Thankfully they’re really only visible when shooting with a closed down aperture like f/22. At f/8 I see nothing! The aperture of a lens describes how big the hole in the lens is that lets light in to the camera sensor or film. Paradoxically, small f numbers are big holes, so f/1.8 lets in lots of light, while f/22 creates a tiny hole and not a lot of light gets through.
Even if you never take the lens off your camera, you might still get spots on your sensor. A zoom lens has bits that go in and out. Air goes in and out and there’s a (tiny) chance that dust will get sucked in. Dust in the lens itself is nothing to worry about as it’ll never show in photos but if you shoot a lot at small apertures like f/22 you can clean your sensor.
It’s actually not that hard to clean the sensor. Last year I wrote a blog post on how to clean your camera sensor including a video and step by step instructions. I’ll probably get around to that this week again. Go have a look if you see spots, or go see a doctor if you’re not looking at a photo at the time …

I want this car to park for me
Tesla will include $8,000 worth of self driving equipment in every car, but you have to pay extra to “enable it” when the software is ready according to this article.

Samsung Galaxy Note 7 Blows Up
Well, that escalated quickly. So this is why they asked people not to use the Note 7 on my flight to Canada..
MacOS Sierra and Lightroom 5
If you updated your Mac to MacOS Sierra and you use an old version of Lightroom you may get a shock when you try to import anything.
The destination and rename panels are missing from the sidebar! Luckily there’s an easy way to fix it, at least temporarily, thanks to The Lightroom Queen who figured out how. Right click on one of the panel headers and you can enable the missing panels again in the menu that appears!
Unfortunately the change doesn’t stick and the next time you import photos you’ll have to enable those panels again if you want to check those settings.
I can’t imagine Adobe will update LR5. I didn’t think Lightroom would start to break down so quickly after an OS upgrade as the app isn’t that old but I guess we’ll all have to jump on the Creative Cloud bandwagon sooner or later.
Ages …
Well, look. At least it’s not like in Windows where it tells you it’ll be done in ten minutes and then five minutes later it’s gone up to twenty ..
I expect this will take a few days.
Find Duplicate Files in MacOS
In the past I’ve used FSLint or even some BASH magic to find duplicate files but I have a huge archive of photos and videos, some of which were renamed during import, and some were accidentally imported more than once, or moved about. It’s somewhat chaotic
So I was very glad to find dupeGuru! It’s a powerful application for MacsOS and Linux that allows you to scan one directory or more for duplicate files. It can search by content, or match filenames. It has modes for music and pictures, but I’ve stuck with the standard search as I want to only look for files that are 100% the same.
It found several gigabytes of duplicates for me, and it has a useful feature that symlinks duplicates to their parent. Even though the dupes still exist, they’re not taking up any space.
The developer is looking for help to maintain the project. You can find more information and source code too on the dupeGuru GH page.
