Thanks for sharing, those photographs are very clear and sharp (especially this one: https://pics.dllu.net/file/dllu-pics/boston-pcc.jpg) it seems to tickle my brain.

This reminds me of Wes Anderson movies for some reason.

His style is to shoot his subjects straight-on. Most other movies have the camera at an angle.

I'm a big fan of Wes Anderson's aesthetics and would love to shoot that funicular train from Grand Budapest Hotel (which actually exists --- the Buda Hill funicular) using my line scan camera.

I have three of those actually:

Technically, the photo could be twice the resolution, since the length of the line scan sensor is 4096. It consists of two lines, RGRGRG and GBGBGB. By interpolating the red and blue channels, it would be possible to get images 4096 pixels tall. The challenge is that the two green channels apparently have quite different sensitivity and also each pixel has some variation in sensitivity, which also seems to drift with temperature and settings, so it's quite annoying to calibrate everything properly haha.
