| It's a bit Web 2.0core but functional enough.

| The style might be, but the CSS isn't, seems there is css

| "open source and open hardware cinema camera" that is, so like
| RED cam or something like it I guess.

| Red is neither open source nor open hardware.

| I believe the comparison was to the class of camera. I.e.

| I don't think RED is open source, is it?
| RobotToaster wrote:
| It's an interesting project, but EUR4k for a camera without

| luto wrote:
| Professional cameras often do not have auto focus, compare to
| some RED camera models. You either prepare your focus points
| ahead of time or you work in teams, where your camera
| assistants act as the "auto" focus.

| If it has a focus ring motor that's controllable via the API,

| Problem with any non-mass-produced camera seems currently the
| availability of image sensors. It seems that the only small-batch
| available sensors are for machine-vision and accordingly priced
| :/ The CMV12000 used here costs $2000-$2200 per sensor - more
| than many full-frame mirrorless cameras.
|
| Another problem is that there are no development boards as far as
| I'm aware. That's why this imo could be huge for anyone else
| interested in making an open camera, the apertus project seems to
| have a modular architecture and breakout board for components!
|
| That said, the sensor does have a globoal shutter which would be
| huge for cinema but not sure at what tradeoffs in dynamic range
| or color-depth eg.
| creer wrote:
| Are broken full-frame cameras becoming available? Where large
| sensors might be sourced from? I see quite a few sensors
| available on ebay. Problem then might be getting specs.
| immmmmm wrote:
| For a global shutter sensor that big that seems kind of
| reasonable.
|
| Been buying smaller sensors, building multi camera machines,
| for researching projects and I like that thing.
|
| Open hardware, i wish I was doing cinema to buy that thing,
| gorgeous!
| dorfsmay wrote:
| Do you write your software to use the small sensor from
| scratch or do you build on top of existing libraries?
| logtempo wrote:
| You're correct, but if a company invest money in this project,
| just like all big open-source projects, it can work.

| Here's another project using a more affordable full frame kodak

| Some people like ccd better than cmos for the color range.

| Back in 2019, I submitted a GSOC proposal for Apertus. They
| wanted to add frame serving capability [1] to their RAW image
| processing software OpenCine [2]. Even though my proposal was
| rejected, I ended up learning a lot from their coding challenge
| [3] which was mandatory for submitting a proposal.
|
| Reading research papers to understand Demosaicing [4], learning
| C++ coding guidelines, RAW file format, code reviews and feedback
| from Andrej and others at Apertus was really fun. At the time I
| was still a sophomore at college so I asked and made a ton of
| mistakes. Thanks Andrej [5] and team for being patient with so
| many of us! :)
