About a year ago I resolved to take a picture at the same time each day for the whole of 2022, and stitch them together into a timelapse.

Setup
As I didn't have a dedicated camera or any special equipment, I couldn't set up anything permanent. I simply marked out a rectangle on my window using masking tape and placed my phone within it every day to take a picture.
Very quickly I realised this was a stupid idea; even if I managed to align it perfectly each day, my phone's camera was always making tiny adjustments to stabilise the image. Granted, they were only slightly off - but when compounded 365 times, I began to wonder if I was even in the same room when I took some of the photos.
Still, I had already started by this point, so I resigned myself to fixing it in post.
Editing
Towards the end of the year, I opened up Affinity Designer and began the arduous process of aligning the photos. This was something I wish I'd done as I went along, I now had hundreds of them that all needed to be manually straightened, cropped, and aligned.
Once I got them reasonably consistent, I stitched them all together in iMovie to make my timelapse.
When played back at high speed the pictures still looked woefully uneven, so I used iMovie's built-in stabilisation feature which was just good enough to finish the job.
Result
Below is the finished timelapse, although I missed 37 days. Seeing things sped-up is always fascinating, there are so many details we miss living in real-time!
