  • Intersecting curves of high resolution and critical focus 6k 8k

    As the megapixel per dollar goes up wit 6K and 8K cameras.
    The people who can afford focus pullers goes down
    The criticalness of accurate focus goes up.

    It's like a crash.

    You need way better focus as the megapixels go up.

    Without something like DPAF or a good focus puller, (some focus pullers aren't as good as DPAF), your image is out of focus.

    It becomes a bit of a train wreck of inverse returns.

    Most of the people affording these cameras don't have focus pullers, and most of these cameras don't even have focus assist.

    Suddenly you have a very high resolution image focused on the brides nose bridge instead of her eye.

    It's like having the fastest car in town, but it can only go in a straight line.

    Good point, but even in HD amateur full frame video is full of focus hunting that rarely hits the mark as if that is a desirable aesthetic.

    That's why I think super16 is so appropriate for the lo/no budget single shooter. There is room to move in wide shots but can still get nice locked down close ups with out of focus background. High quality full Hd is more than good enough for big screen narrative. Older actors will thank you not to use 4k and higher. If you have to use heavy diffusion to work at higher resolution, what are you really gaining.

        Or you could just stop down a little.

          He means there will be more people out there shooting who are operating on tiny budgets that don't allow for a Focus Puller to be hired. The insanely low price of these new cameras makes this a much more common scenario.

            Exactly!

              Narrative has always required manual focus, regardless of the format or resolution.

              Higher resolution cameras will highlight mistakes, but those are user errors that would have been there despite the resolution. There have been low budget video shooters since DSLR's got video capability, and since then the lack of a 1st AC has always been a problem for ultra low budget indie projects. Hell the no-budget-indie sector has been around since 8mm film.

              More pixels makes it easier to nail focus by eye. An experienced ENG shooter can pull for themselves.

              I think what you're observing is that with cheaper professional gear, you get an influx of amateur and novice shooters, and the wake of content that follows. Yes of course there is going to be a ton of poorly produced, poorly shot content.

              If anything it makes it easier to set yourself apart from that crowd if you know what you are doing.

                The invention of the printing press has made it easy to spread a lot more bullshit than writing by hand. Does this say anything about the masterpieces of literature?

                  Note: Focus on the brides eye, not her nose. You'll be golden with these hi-res cams.

                    If you can't see that extra resolution, then it doesn't require higher precision when pulling focus. So, this is only an issue as long as the extra resolution is showing in your footage. I have very good vision and with 4k vs 1080p this only happens when I zoom in on a clip: 1080p won't allow it, with 4k I can go 167% and it still looks sharp. It's that kind of situations that will require higher focus accuracy, and really, if the choice is between "only" being able to go to 167% or being able to go to 250% but only if I also nailed the focus, well, it's a small plus but it's a plus.

                    My bigger point is: you can either argue that higher resolution has very limited value in real life, or that it requires higher focus precision, arguing both is a contradiction. I'd go with the first one.

                      Yeah, it is strange that amateurs for over a century have been able to take pictures with 8x10 view cameras just fine but videographers think they aren't going to be able to use the tiny sensors of "full frame" cameras.

                      I enjoy photography forums so much more. People with experience give advice to less experienced people and help them mix chemicals, coat old school plates, and build cameras. Everyone chips in and tries to help people do the best with what they have. Videographers just sit around telling everyone "it's not possible, it's not possible."
