just imagine a camera app where
- all common hardware features and lenses are supported
- it has a pro mode tab
- it doesn't crash every minute
- it doesn't add weird filters that you can't remove to 87.123% of photos with weird obscure conditions (software magic AI ML bitcoin blockchain agile image enhancement)
- the UI isn't ugly as shit to the point of being barely usable

do I just carry a separate digital camera with me everywhere

@AgathaSorceress oh and

  • it lets me use the maximum resolution in pro mode (or support it at all but apparently it’s just vendors with their absurd >24MP cameras locking the higher modes behind the stock camera app with less features than the basic mode)

@AgathaSorceress there is like no reason why my 50MP camera cannot actually shoot 50MP images! unless they are just oversampling a smaller sensor which sounds like false advertisement to me

And no there is literally no reason why i would want 100MB raw files but i still want them

@AgathaSorceress from what i can tell my new phone’s camera actually has a smaller sensor than my old ones? the stock camera shoots smaller images in RAW mode

@AgathaSorceress what phone do you use now?

@AgathaSorceress I found Open Camera to be the best one on F-Droid.
https://f-droid.org/packages/net.sourceforge.opencamera/

FreeDcam has the most options. It's UI is a bit to clunky for me in day use. So I only use it, when I need it's features.

@charlotte @AgathaSorceress this is what my camera calls 40 megapixels bluefox_dicaprio_derp

I think they calculate the resolution based on that of the bayer matrix. That being said, I'm not complaining, I have plenty of resolution enough it's mostly color accurancy and (the total absence of) low-light capabilities that I'm less happy about
It's a screenshot of my photo g…

@miifox @AgathaSorceress a 40MP image sensor creates a 40MP image after debayering, yes it's calculating information out of nothing but this is how digital cameras always worked. Try shooting raw, the size in megabytes is 2x the amount of megapixels (a 12MP camera will shoot 24MB raws)

@miifox @AgathaSorceress your phone's camera app likely offers an ultra resolution mode that lets you shoot 40MP images, but it probably has less features than basic mode

@charlotte @AgathaSorceress my phone's camera app? Have you seen my phone's native camera app? I think in the prehistory they had bettter apps bluefox_rotfl

@charlotte @miifox @AgathaSorceress Though it is making up stuff in the debayering process it is not completely out of nothing so to speak, this is one reason why it is so hard to set a limit on what the comparative resolution of film is. e.g. if you believe the (de)bayering process looses no information at all a 4x5 sheet of film is about 100MP, while if the loss would be full the shame sheet would be 400MP equivalent, neither end is really true but the amount of loss is scene dependent (a scene lit by blue laser light would be closer to the 400MP end, while a grey scene lit by a white light closer to the 100MP end). Also with the advent of computational photography most phone cameras make up a lot more than just debayering (without computational photography a 20~24MP FF sensor + descent glass would beat any 50+MP phone sensor even with some generational differences)

@deetwenty @charlotte @AgathaSorceress yeah, my 2019 phone is comparable in quality to a 2012-2013 iphone (I know that because that happens to be what I upgraded from). I think the amount of processing it does is limited, I understand the argument of photographers to save in raw but that's not something that the stock rom of my phone's android supports (I think in forums I read about modding it but really, this camera ain't worth it). Film is different though, film grain depends on a great amount of factors and to compare it to display matrix resolutions is questionable at best imho

@deetwenty @miifox @AgathaSorceress i mean yeah, the individual color samples are taken from slightly different positions (due to the way the filter works) and generally a change in one color corresponds to a change in the other color channels so you can actually get a pretty good idea what the other colors *should be* behind samples from the wrong filters

That said i do wonder if they make mirrorless 3 sensor cameras (like video cameras with 3ccds)

@miifox @charlotte @AgathaSorceress Nyquist sampling theorem is still applicable, and that combined with MTF diagrams can give you an idea of what the equivalent resolution could be (of course this then gets into anti-aliasing, debayering, etc, so is not an easy thing to do)

@miifox @deetwenty @AgathaSorceress most phones have no hardware for processing images, i think only google pixels do

@charlotte @miifox @AgathaSorceress Not that I know off, though many mirror less cameras do offer a pixelshift mode that can replicate the effect of a 3 sensor camera (at least for static scenes)

@deetwenty @miifox @AgathaSorceress honestly scanning film at the highest possible quality and continuing to preserve the original as well as possible is good enough
