  • Are you using something to hold your camera, like a tripod, and some kind of jig/fixture to hold the film in place? Ideally you wouldn’t need to touch the camera and the film would be positioned consistently between shots. Without some kind of setup scanning will be very fiddly as you need to be perfectly centered/squared/etc.

    Could the camera possibly be moving some between shots? Are you shooting wide open?

    As for focus changing with lens rotation, that would indicate something in your lens lacking axial symmetry. An uncentered/decentered element, an element that’s not ground just so, etc.






  • Some level of rotational play on lenses is normal, but one wouldn’t normally put enough torque on the lens for it to be an issue. It sounds like the focus ring is a bit stiff? It might loosen up some with time, but I have not ever used any TTArtisan glass.

    Simply rotating the lens relative to the body shouldn’t impact focus. Focus is all about the distances between elements relative to the sensor and rotation shouldn’t change that.

    If you’re looking for opinions it might be worth popping over to something like Fred Miranda or DP Review if no one else here can chime in. Sadly, the fediverse is somewhat small and those sites have big/active forums.


  • Same, but I do have some level of worry regarding portability. My solution isn’t local or self hosted, as I was looking for easy and works across Linux/Windows/Mac/Android/iOS. I do not look forward to needing to change to a new password manager in the future, but given the way everything seems to be going it seems likely that I’ll have to at some point.




  • So much the same. In this market I would rather stick around with the devil I know beii have a good reputation and network. I don’t want to be the new person somewhere else should things go sideways. Grated, I am very much on the chopping block at my current employer given the waves of layoffs and “performance frings” that have been happening…


  • I saw the title and community and thought it was you. Then I saw the user name and was surprised.

    There are a bunch of us lurkers out here I suspect, so keep up the good work! I appreciate the design/engineering that goes into things like knives and flashlights, but I don’t really have a need to collect a bunch. But content like this, and yours, makes it much easier to choose which things to try vs which to skip.

    I mean, I’m happy to post a “but sure recommend me an x” post. I could probably make two: one for a knife and one for a multi tool.





  • I got curious and will attempt some math and duckduckgoing.

    A forest can remove between 4.5 and 40.7 tons of Carbon Dioxide per year per hectare during the first 20 years of tree growth. Sauce

    Humanity is currently generating around 40 billion tons of CO2 per year. Sauce

    So now some simple math: it would take between 1 billion and 10 billion hectares of forests, depending on their maturity, to keep up. 100 hectare = 1 km2 sauce, so this means 10 to 100 million km2 of forests.

    Earth’s total surface area is 510 million km2. sauce.

    Of that, here’s a quick breakdown:

    Sauce

    So 10ish percent of the 510 million km2 of land on earth, or around 5.1 million km2 is a good candidate for tree planting. That’s not enough if we want to sequester all the carbon produced by humanity. Without getting to net zero global warming will continue. The best we can do is slow it down. More disconcertingly, our appetite for energy is only increasing. The good news is that we’re really starting to see large scale wind and farm operations ramping up, but there are still a lot of power plants scheduled to come online in the next two decades.
