Godox TT350

I decided to get a better flash for better portraits, and with the Godox TT350 being available for only $120 at the local photo store, I took the plunge.


Puluz 45cm Round Diffuser

I knew I wanted a big diffuser to go with my Godox TT350. The salesman at the camera store recommended a $140 Joe McNally Ezybox Speed-Lite 2 Plus, but given that the flash unit itself only cost $120 I balked.

Would a $25 diffuser do the job? Turns out it did, and very well indeed.


Backblaze B2 Cloud Storage

The same low price as Amazon's Glacier, but with instant retrievals and a cost structure that you don't have to be a superhuman AI to understand? Backblaze's B2 Cloud Storage has a very compelling offer.

Signs of Spring in Hansta

Spring is here - and it's the blue siblings of the wood anemones that are first up through the layer of last year's dead leaves.


Blindsight by Peter Watts

I think Peter Watts is trying to tell us that he isn't conscious. Besides being a science-fiction version of The Ego Tunnel by Thomas Metzinger, Blindsight is a story that sets out the author's argument that consciousness is an evolutionary mistake and that we would be much better if we would just let our unconscious get rid of that slow and unnecessary awareness.

The book is good enough that I'd be willing to buy that argument if he'd reveal that it was written unconsciously.


Sigma 70-200mm f/2.8 EX DG OS HSM

This lens was as close to an impulse buy as I'll ever get. When going from crop-frame sensor to full-frame I had to upgrade not just "normal", day-to-day lenses, but also the ones I use for dance and concert photography. I think I did a single search on Prisjakt and then went out and bought this lens.

It was a good buy.


The Ego Tunnel by Thomas Metzinger

Theories about what consciousness is tend to disintegrate into either hand-waving or mysticism. While Metzinger's attempt falls into the former category, he does manage to put up quite a good fight before going down: the goals he sets himself are the right ones, and when he finally does start to become vague it is only because empirical science hasn't yet reached that point.

The Needle Dam on the Reuss

A needle dam across the Reuss, maintaining the level of Lake Luzern. It consists of many small planks, called "needles", that can be added or removed to restrict the flow. The needles don't block the flow completely - and this is not the purpose: it's to manage the flow, not stop it.

JYC P9 Flash Diffuser

When shooting with flash you may have observed sharp shadows or bright highlights on people's skin. Those are both caused by the flash being close to a point light source. Point light sources give rise to sharp shadows, since, as seen from the shadowed object, the light source is either completely visible or completely hidden. They also result in very bright highlights for the same reason - either the beam bounces completely back to the observer, or it doesn't. A flash diffuser alleviates this by expanding the area the flash beam originates from, and therefore the different angles the light strikes the object.
