This is the “oops” list! A series of photographs of unfortunate aviation events. Here’s a dramatic example!

A9.com -Yellow Pages – Copyrighted Buildings?
Nice, the Yellow Pages on a9.com have photos of the places you’re looking for, as long as you live in the good ol’ US of A!
I wonder if they got the permission of all building owners to take their photos. The images of all buildings built after 19xx are proteced by copyright.
Ah, here’s the details. It’s all buildings built after December 1st, 1990. In general any building viewable from a public place is ok to photograph.
The a9 search engine is nice too!
Creating Panoramic Photos with the GIMP
Caoimhe asked me to elaborate on how I created the panoramic photo that currently appears at the top of this page. Here’s how. You can download all the images I used (although they’re much smaller than the originals!) but the techniques described will be useful for other photos too.
- Load dsc06627.jpg, dsc06628.jpg and dsc06629.jpg into the GIMP.
- Create a new 1920×640 RGB image.
- Copy/paste dsc06629.jpg into the new image and move it to the left of the frame.
- Look at the layers dialog and right click on “Pasted Layer” and select “New layer”.
- Do the same for dsc06628.jpg and dsc06627.jpg moving them over to the right before making them into new layers. No need to line them up right away.
- Now line up “Pasted Layer#1” with “Pasted Layer” as best you can. It helps if you select “Pasted Layer#1” and move the Opacity slider to about 50%. Concentrate on getting the right side of the layer lined up with the bottom layer. The left side is always overlapped by the layer above.
- Now set the opacity to 100% again! You’ll hopefully see the mountains in the background join up nicely!
- You’ll have to adjust the colour of “Pasted Layer#1” – Use Layers->Colours->Colour Balance, and Hue-Saturation. Don’t worry if the colours don’t match exactly.
- Do the same with “Pasted Layer#2”. Getting the trees lined up is a bit of a pain because of the branches, but if you clone out the branch tops after aligning it helps.
- When that’s done, you need to match up the layers using a layer mask and a gradient: select “Pasted Layer#1”, right click, and click “Add Layer Mask”, and click “OK”. Select the gradient tool (press “L” if you can’t find it) and draw a gradient from the top-left corner to the center of the layer. Click on the layers dialog again and “Apply Layer Mask” and then use another gradient on “Pasted Layer#1” to match up the right of that layer with “Pasted Layer#2”.
- Crop the image, remove the white background and get rid of the rough edges!
You can look at sneem-panorama.xcf to see the layers and effects I used.
As part of your digital workflow you should also use the Layers->Colours->Curves, Hue-Saturation and Levels tools, and Filters->Enhance->Unsharp Mask plugin to improve the final image.
Sneem Sunset – 3 photo panorama
The picture above is a panorama made up of 3 hand-held shots taken in Sneem, Co. Kerry.
Stitching them together in the GIMP was fairly easy – adjust colours and brightness, line them up using semi-transparent layers and then use a layer mask and a gradient to make the joins mostly invisible. The tree branches were a bother though – I had to clone out some of them!
I really should document some of this stuff as this was a good example – because of the sunset each photo had very different light qualities and it was important to fine tune and match those colours.
F-Spot mini review
I like F-Spot. It’s useful, it does tagging that no gqview and gthumb don’t. It has organisation features that they don’t have either, but it’s a little too buggy for widespread use yet.
It was really easy to use however. Just “import” a few directories of photos, create a few tags, and then select a few photos, right click and add a tag to those photos.
Unfortunately it crashed a few times after an import, and exif reading seemed to be completely broken but then I never checked if the proper library was installed. Except for rotating, I *never* use a simple photo viewer to manipulate images so I didn’t try out those features of the app. IMO that’s a job for the GIMP and I save modified files to a new directory.
I’m going to keep a close eye on it to track how it progresses. It’s shaping up to be a great desktop application!
A hint for Gnome users – if you haven’t got much room in your home directory move the “~/.thumbnails” folder out of the way somewhere else with plenty of space and symlink it back. Mine’s at 171MB and growing fast!
While we’re on the mono theme, a mono developer, zbowlin1 on #wordpress attracted my attention when he said..
<zbowlin1> I just did something really really cool. I have a much better version of php+gtk by calling the GTK and System.Windows.Forms (SWF/MWF) classes using PHP as a runtime and using the .NET/Mono invoking classes in PHP 🙂 <zbowlin1> I just made php as runtime and used GTK# like a runtime, and used my Gecko# port and opened a stream and used PHP methods like calendar and Smarty and stuff to generate the content for the page.. most php scripts should work and you can run them and render tables and stuff in gecko#/gtkhtml windows and the rest in lables and menus <zbowlin1> its like a much much better, cross platform (thanks to mono), PHP+GTK that kills the crap out of the need to make stubs and makes it gtk2 compatible and opens up billions and billions of possibilities for people who only write PHP or people who want to code one set of common functions for like an application version and web page version.. and it can work on the fly <zbowlin1> humm… i’m on the mono team and i’ve working on my C# based offline wordpress blog writer with a WYSIWYG interface and spell check.. this just made that idea like 3923501235 * better <zbowlin1> i don’t have to rewrite interfaces. I can use built in php xml-rpc support. AAAAH man it boggles the mind the amount of possiblities.. <zbowlin1> you can gain access to xpcom in mozilla so you can automate XUL with PHP… you could write Mozilla extensions php.. you can call anything, or do anything, on mac, windows, linux, freebsd, etc.. <zbowlin1> holly crap <zbowlin1> i’m mind boggled <Firas> XUL and GTK are pretty different toolkits? <Firas> * aren’t <zbowlin1> they are very different <zbowlin1> but xul will render with gtk and gtk2 if you have them <Firas> oh, right <zbowlin1> but it also render with QT, Win32, Cocoa, BeOS, etc <Navid> XUL is nuts. I need to pick up on that. <zbowlin1> you write everything mostly in javascript and xml <zbowlin1> you could write the blogging interfaces and menus into my interfaces… if you have local access to the database it should work that way but you could automate it with some work and make it work with XML-RPC
zbowlin1 is at zacbowling.com and go-mono.net
I always want to create cross-platform applications, if .net and mono can do that I need to look more closely at them!
Photojournalist Student Kicked Out Of Dorm
A student at San Francisco State University has been kicked out of his dorm for taking “pictures of partying, binge drinking, oral sex and, in particular, an alleged car burglary”. Here’s the latimes story and a thread started by Omar Vega himself.
What would you do if you saw someone breaking into a car? Take their photo or stop them?
F-Spot – Picasa like application for .net, mono and Linux
Liam’s going on again about how great the combination of “picasa + hello + blogger + ftp” are on IRC but unfortunately Picasa is a Win32 application so it’s not something on my radar.
He says that F-Spot is a similar application, developed using Mono so it’ll probably make it’s way to Windows .net too.
If you want to install it on Debian Testing you’ll need to install the unstable port using the following:
Add “unstable” to your /etc/apt/sources.list:
deb http://ftp.somehost.com/debian/ unstable main
Then edit /etc/apt/preferences and set the “pin priority” of unstable lower than testing. This means that “testing” packages will be installed before “unstable” ones.
Add these lines to /etc/apt/preferences:
Package: *
Pin: release a=testing
Pin-Priority: 650
Package: *
Pin: release a=unstable
Pin-Priority: 600
Thanks Niall for that last bit!
Now, install f-spot:
# apt-get -t unstable install f-spot

Winter's Day at Iniscarra
The sun set slowly last Sunday. It was a cold but glorious day!
Why Focus-Recompose Sucks
I use this technique, as do most photographers I’m sure, but it can make the subject of your photograph blurry as the auto-focus is focused on a slightly further back point. It makes sense when you think about it but it’s still useful when you have a long depth of field. Anyway, here’s the explanation why it’s not good for portraits and other close-camera work.
The Job of a Photo Journalist
Mark Hancock, as a photo journalist, is exposed to situations that many of us never see. A police warrant roundup is one such occurance and he describes it well.
He has several things to say in his accompanying post about what PJs do:
Before I continue, PJs mostly cover tax dollars at work. When we cover wrecks, fires and such, we focus on what the police and firefighters are doing. This is why we are there. We also cover the people affected by the event to get them help from the community. Lastly, we cover the people who may have caused the commotion in the first place (hostage takers, etc…).
