Earlier today, I wrote about AI and photography based on an interesting panel conversation at Fotografiens Hus in Oslo. During the Q&A session, a musician in the audience said that he felt that the AI systems he had tried behaved so properly and asked if an AI can be “drunk” and whether we could “pour some alcohol into the machine” to make it a little freer and less “stiff” in its creative output. That is a very interesting question, hence this little reflection. ...
Today, I took part in an interesting panel conversation at Fotografiens Hus in Oslo in connection with the exhibition What We Call Real by Camila Urrego. This was the first time they had invited a photographer to exhibit works explicitly made “with AI,” and I was invited to contribute thoughts on the potential of AI for creative practice (in this case, photography). As MishMash picks up speed, I receive many requests for talks and panels on AI and creativity, and I try to say yes when I can make it. I have found this to be an excellent way to think about various AI use cases outside my core focus areas and to meet interesting people. Here are some thoughts based on my preparatory notes and reflections after the event. ...
In this post I write about how it is possible rename all the photos in a folder based on the date and time information stored in the file. I mainly take photos with my mobile phone these days (a Samsung Galaxy Ultra S23) but occasionnaly also use “regular” cameras. As opposed to my phone, which saves the files with a filename that includes date and time (YYYYMMDD_HHMMSS.jpg), these cameras typically just use some random name (e.g. P43435.jpg). This is impractical when combining photos from several cameras, so I prefer renaming the files with the same filename schema. ...
I use a GoPro Max 360-degree camera in my annual #StillStanding project. That means that I also have had an excellent chance to work with GoPro files and try to understand their inner logic. In this blog post, I will summarize some of my findings. What is recorded? Recording “a video” with a GoPro Max results in recording multiple files. For example, each of my daily 10-minute recordings ends up with something like this: ...
For my annual Still Standing project, I am recording 360 videos with audio and sensor data while standing still for 10 minutes. I have started exploring how to visualize the sensor data best. Today, I am looking into visualization strategies for 360-degree images. I have written about how to pre-process 360-degree videos from Garmin VIRB and Ricoh Theta cameras previously. The Theta records in a dual fisheye format like this: ...
I have previously written about how to resize all the images in a folder. That script was based on lossy compression of the files. However, there are also tools for optimizing image files losslessly. One approach is to use the.jpgoptim](https://github.com/tjko.jpgoptim) function available on ubuntu. Here is an excellent explanation of how it works. Lossless optimization As part of moving my blog to Hugo, I took the opportunity to optimize all the images in all my image folders. That was done with this one-liner: ...
A quick note-to-self about how I managed to download a bunch of photos from an iPhone and convert them to.jpg on my laptop running Ubuntu 22.04. As opposed to Android phones, iPhones do not show up as a regular disk with easy access to the DCIM folder storing photos. Fortunately, Rapid Photo Downloader managed to launch the iPhone and find all the images. Unfortunately, all the files were stored as HEIC files, using the High Efficiency Image File Format. This format is technically good but practically tricky to work with. So I wanted to convert the files to.jpg. ...
This is a note to self about how to programmatically resize and crop many images using ImageMagick. It all started with a folder full of photos with different pixel sizes and ratios. That is because they had been captured with various cameras and had also been manually cropped. This could be verified by running this command to print their pixel sizes: identify -format "%wx%h\n" *.JPG Fortunately, all the images had a reasonably large pixel count, so I decided to go for a 5MP pixel count (2560x1920 in 4:3 ratio). That was achieved with this one-liner: ...
I often find myself with a bunch of images that are not properly rotated. Many cameras write the rotation information to the EXIF header of the image file, but the file itself is not actually rotated. Some photo editors do this automagically when you import the files, but I prefer to copy files manually to my drive. I therefore have a little one-liner that can rotate all the files in a folder: ...
Flickr has opened for uploading videos, or, rather, what they call “long photos”. As such, they are not trying to compete with YouTube or Vimeo, but rather making it possible to upload videos that are closer to a photography than a movie (i.e. with a narrative). I like this approach, and it resonates with how I am often recording a video as if it was a photography. The difference between what I could call a photo video and a movie video, can be seen as analog to the difference between music compostion/production and soundscaping. Composition/production is about organizing sonic events in time. Soundscaping and field recording is about capturing and reproducing sound. ...
