I learned quite a lot from the financial models of modern capitalism. I always found these models to be severely lacking in common sense (not that it’s a good reason to ditch them), and to be used in a malicious way, imposing laws and lowering protections for no good reason. A model is only as good as the assumptions that it makes. Any decision made based on the model results without considering them is ridiculous.
And I knew that politicians imposed some of these laws after a shock. We can see that after the terrorist attacks in Europe in the last decade, but I didn’t realise that their security laws were actually entirely part of the neoliberalism doctrine. Enters this book.
Sometimes in night photographies, we get some odd colors that are not natural but due to defects in the lens we use. These happen more with a wide aperture which is what we would use in night photos. A small trick is possible to fix this.
In the previous entry, I just stacked 58 photos without any additional thoughts to get a nice simple photo. It is time now to go one step further. What are the steps required to stack astrophotos together?
I’m a white, cis and athletic male, the archetype of a privileged person. Sometimes we thing that it’s being woke to try to figure out when we do have them. I reviewed a book about race, read others about gender, but I didn’t think about my build. Well, I was wrong.
Our immune system has been quite a central topic the last couple of years. When Philippp Dittmer wrote his take on the subject, I was interested, as Kurzgesagt is one of the best science Youtube channel there is!
I love photos, and I’m beginning to get into astrophotos as well. One issue I face is how to get long exposures from the sky when you have light noise. I want to see arcs in the sky, but the longer you expose, the brighter the background becomes. The same problem occurs if you are using a polar tracker, you get more light, but also more noise!
So I decided to get a small script together to generate images like this one:
It feels a little bit artificial because the noise is minimal and because there are not that many small stars, but it’s a good start. The script is very easy, it just reads all images from the command line pattern, and then gets the maximum pixel value for all pixels across these images. Saving in “result.jpg”, and this is it!
