GoMA Queensland Gallery of Modern Art

One of the cool things about living in West End is that it’s only a short walk down to the Queensland Cultural Centre.

The Queensland Cultural Centre is a multi-venue centre located at South Bank, Brisbane, capital city of Queensland. It consists of the Queensland Performing Arts Centre (QPAC), the Queensland Museum, the State Library of Queensland (SLQ), the Queensland Art Gallery (QAG) and the Queensland Gallery of Modern Art (GOMA).

Timelapse DSLR, Ubuntu 10.10 gTimelapse and eeepc how to

I’ve played around with gphoto2 quite a lot and I knew there was a simple way to get my DSLR camera to take a photo every 10 seconds and copy it to anywhere I’d like. When googling how to do this I found a really nice application with a gui call gTimelapse. It amazes me that programmers just decide to write these programs and share them openly on their websites including the source code. gTimelapse is written by Tim Nugent, its a really nice program for doing timelapse, really simple to set up and easy to use. I like the preview and thumbnail preview of all the images it captures as it goes along in real time. Big thanks to Tim for this awesome program.

I thought I’d document the extra packages I needed to install to make it easy for other Ubuntu users to compile the program. Basically download it from the link on the page at Tims site then extract it somewhere and run the following commands.

$ sudo apt-get install build-essential libgphoto2-2-dev libwxbase2.8-dev libwxgtk2.8-dev gphoto2
$ configure;make;sudo make install
$ gtimelapse

The program will start and the rest is fairly straight forward. You probably want to change the max frames to 0 so that it records till you press stop. The other tip I would suggest that if you stop and start capturing make sure you set a new “Working Directory” in-between otherwise you will just overwrite the images you just captured.

I was pretty lazy and left a comment asking Tim for his mencoder command to put together the images at the end, his response was really quick which was nice.

Hi Chris, I think there should be a script in the src directory with some decent mencoder settings? Ah here we go, will make a 720p HD vid for Vimeo etc:

mencoder mf://*JPG -vc ijpg -mf fps=8 -vf scale=1280:720 -ovc x264 -x264encopts bitrate=5000:keyint=30 -o timelapse_1280x720_x264_8fps_5000.avi

Though I found that too jerky for my needs, Im sure its fine for his party video but I wanted moving clouds in mine so I changed the fps=8 to fps=25 and it was fine.

The other thing was that I shot in jpg normal which is 2144x1424px and I wanted my video to be 720p so I used David’s Batch Processor Gimp plugin to resize, crop and sharpen them a little before using mencoder. That gimp plugin worked really fast, its great.

It seems time consuming to capture the images, when I captured every 5 seconds for 30 minutes then encoded at 25 fps it only gave me around 14 seconds of video. So be prepared to spend a few hours to get a decent video. I think with my eeepc and nikon d90 with battery grip going outdoors I can capture for around 6 or 7 hrs.

When I went out to try this the weather was really crappy but it didnt turn out too bad, you can watch my video below or watch Brisbane Morning Time-lapse Test on youtube.

GNU/Linux Extract JPG from RAW, NEF, CRW using terminal, Nautilus, Digikam

[youtube_sc url=http://www.youtube.com/watch?v=jGeHGTuOJy8 width=640 rel=0 fs=1]

A common question by photographers who shoot in RAW is how to get a jpg the same as the one the RAW image file produces from the camera by using the RAW image file and a software package. In the screencast I talk about how to do that. Watch it above and you can also watch GNU/Linux Extract JPG from RAW NEF CRW using terminal, Nautilus, Digikam on youtube.

Geotagging, Ubuntu and Nikon NEF with Digikam


I haven’t made a screencast in a long time but I decided to share some info mostly about geotagging. I own a Nikon D90 and plan to buy a GPS unit that will write the global position system data to the exif metadata of my photographs and make them more manageable for me and allow me to do some cool things for visualising a map of my photographs.

I’ve been using a lot of programs to manage my photos but Im starting to settle for using DigiKam at least while using my best computer. The other program I talk about in the video is geotag.

A platform independent program to geotag images(use GPS data to store location information with the image).Uses external maps to fine-tune locations.

Anyone can use geotag to tag their photos very easily. Watch my video below.
