Forest Overflowing

If you walk on from the chapel in Gougane Barra you’ll come across the Gougane Barra National Park, which was the first national park in Ireland when it opened in 1966. It is a beautiful place to walk, and well worth a visit.

Christian Radich in Cork Harbour

The Christian Radich is a beautiful sailing ship that’s in Cork Harbour this weekend. I took advantage of a foggy morning to get some photos of it and the surrounding docklands.

Christian Radich is a Norwegian full-rigged ship, named after a Norwegian shipowner. The vessel was built at Framnæs shipyard in Sandefjord, Norway, and was delivered on 17 June 1937. The owner was The Christian Radich Sail Training Foundation established by a grant from an officer of that name. Wikipedia

Light Painting with the Moon

The Moon over Lost Lake, Canada. A long exposure shot with a series of quick movements of the camera to draw a W for WordPress, of course.

Thanks Dennis for the help drawing it in the right direction. 🙂

The Sky was on fire

Sometimes you look out the window and see an amazing sky. Sometimes the sky is on fire.

Now when I say that phrase I think of the sky as it was in Neal Stephenson’s latest book.

Samsung Motion Photos for Street Photography

The Galaxy S7/Edge can take photos with a few seconds of video before the photo. iOS and Windows Phone devices can do the same, as I’m sure many other phones can. I was curious about how well it would work on the street, as it might be useful to show how a shot came about. Surprisingly, it worked well! I could even take two photos in quick succession, and the phone would record overlapping video for each. I didn’t notice any lag.

The phone records the motion photo as a regular jpg file. It’s much bigger though, as there’s a mp4 video files appended to the Jpeg image. You can find some technical info about the file format here.

Yes you can manually do this is 10 seconds with a hex editor by opening your original Photo and searching for MotionPhoto_Data then select everything above MotionPhoto_Data and copy and paste it as a new file and save as a JPG. Do the same for the MPG BUT this time select every thing BELOW MotionPhoto_Data make sure for either one you are doing not to copy the MotionPhoto_Data text. Also the hex for the MotionPhoto_Data is 4D 6F 74 69 6F 6E 50 68 6F 74 6F 5F 44 61 74 61.

Technically the JPG ends at ÿÙ or FF D9 so the ÿÙ SHOULD be included too.
Technically You really want to delete all this “……..Image_UTC_Data1458170015363SEFHe……… ..#…#…….SEFT..0…..MotionPhoto_Data”
But if you leave all this “……..Image_UTC_Data1458170015363SEFHe……… ..#…#…….SEFT..0…..MotionPhoto_Data” in the end of the JPG you can easily merge them back together and have the display and play on your phone

I was going to create a shell script to extract the image and video files but I found this Ruby script that does the same. Saved me searching binary files and splitting them. 🙂

For this first test of motion photos I just used the phone to extract the images. Here’s what I did:

  • Load up Samsung Gallery, and select all the motion photos. Then tap the share button, and a popup appears asking to pick picture or video. I picked video, so it worked away for a few seconds, up popped the list of sharing applications and I hit back. The videos were now in my Camera folder next to the Jpeg files.
  • Copy files to computer, but rename videos (add “-1” or something to the end). Lightroom stacks jpg/mp4 files and it’s not possible to edit Jpeg files when they’re stacked like this.
  • Backup Jpeg files, run them through an optimizer to remove embedded videos. ImageOptim will half the file size.

  • Import into Lightroom.
  • Edit Jpeg files, upload mp4 files and have fun!

Sometimes ImageOptim messes up and Lightroom shows the image as a sort of double-image with interlaced lines like this:

If you don’t have any backups, I found I could fix the problem by loading the image in GIMP and saving it again. Then I’d have to update the EXIF data or overwrite it in Lightroom.

Using the Ruby script above is even easier. Point it at your import directory and it’ll extract any images and videos it finds, appending “_Extracted” to the filename. It’s probably worth renaming them in some deterministic way to avoid the stacking problem I talked about above. Since it extracts everything, you can delete the original jpg file. I should modify the Ruby script so it does the rename step..

I doubt I’ll use this feature much but I’m sure I’ll use it from time to time.
