  • The r50 can do electronic shutter or second curtain shutter, but it doesn’t have a global shutter or full mechanical shutter.

    So, some ELI5 background on camera sensors. Most sensors read the data from the sensor pixel by pixel, line by line. So what that means is that a small amount of time passes between reading the top lines of the sensor and the bottom lines of the sensor. Most of the time, this doesn’t make much difference. But for fast moving objects (or if you’re panning the camera really fast) it means that the scene can change during that passage of time, which is what gives you trains that lean to one side and propellers that look like they’re made of rubber.

    To get around that, you can use a physical shutter. Cameras with “second curtain” shutters physically close off the light to the sensor before they start reading data from the sensor. This means that even though time passes between reading the top and the bottom of the line, the light captured by the sensor does not change during that time, and so the wobbly subjects don’t happen.

    A camera with a full mechanical shutter puts a physical shutter at the beginning of the process and the end, but the gains over second curtain only are negligible.

    In theory, there is also “global shutter” which is a camera that reads the entire sensor at once, but in practice, this technology doesn’t exist at the consumer mirrorless camera level.

    Electronic shutters aren’t all bad though, because they let you do faster shutter speeds than are possible with physical elements, and they let you do higher fps when shooting in burst mode. And electronic shutters are also silent


  • The way I see it is the rules exist to improve the experience of the community. They set guidelines to help us achieve that. The rules aren’t the final source of truth though, the quality of the community is.

    So, if you see something that breaks the rules and is pulling the community down in doing so, use the report function, and highlight it.

    If it’s breaking a rule, but not harming the community, then just let it fly.

    I have no interest in enforcing rules for the sake of rules. I see them more as guidelines for fostering a better community, and that’s the lens through which I moderate.








  • Can confirm

    Image description: A screenshot from a birdpi, a device that identifies birds by their song, and catalogues their activity vs the time of day. The image shows a small amount of activity from a Barn Owl at 10pm and 1am. It also shows a very large volume of activity at 7am from crows, and other Australian birds






  • I scored the highest tertiary entrance rank in my school without studying a day in my life and had my pick of any university course or career. I went to university, and excelled at exams, but because I had undiagnosed ADHD and had never learned time management, I couldn’t cope with assignments that couldn’t be thrown together at the last minute in my lunch break. I was academically excluded.

    So there was that. Basically, my life has continued to look like some variation of that experience since then :P
