    All we need now is a powerful GPU (i.e. the processor for handling video display), an SLR-like light sensor (to sense the environment), and a 4K pixel LED emitter array, each with their own lens, to produce an arbitrary beam pattern on demand.

      that's all i know. i've never dealt with anything over $500 when it comes to cameras.

        Ah yeah. I mean I used a budget Nikon D3100 for 7 years. It took significantly better photos than even the best phones 90% of the time, but the D7200 I have now is such a huge huge huge step up. Even though it's still APS-C, the photo quality just POPS.

          i've considered getting a really nice camera, my dillema though is that my xs-i is still fully functional, and has depreciated so hard it's hardly worth selling...

            I wouldn't recommend it unless you feel like your skill/needs exceed your current camera. I was using a D3100 for 7 years or so, and it's as budget as you get. Many mirrorless cameras easily outperformed it. But it suited me. I finally upgraded due to feeling I finally needed more, plus my birthday, plus a great deal was found.

              yeah, the only thing i really miss that newer/better cameras have is the higher capture rate.

                I never had a need for that, since I did mostly nature photography. I was missing mirror lock, exposure delay, auto bracketing, and a lot more stuff that budget DSLRs can't do or do poorly. Much of this can even be done by mirrorless cameras on the budget side.

                  A big part of the closing gap is how people look at photos. Most people look at photos at "phone size". The lower the viewing size of a photo the easier it is to get satisfactory image quality. Blow both photos up on a 50" 4K screem and the difference becomes apparent. But nobody besides geeks with more money than sense like myself do that.

                  Plus those cheapo Costco kits come with lenses that are so slow cameraphone lenses honestly put nearly as much light on the sensor. Cameraphone sensors also have tech that SLR sensors don't, further closing the gap. I still enjoy the versatility of multiple lenses, and my camera has a full frame sensor, but the advances cameraphones are making are hard to fault.

                    My Mate 9 has a Leica dual camera setup with optical image stabilization. It's incredible, not just for a phone, but overall. Still, my new 50mm f/1.2 makes me wet in the pants.

                        I highly doubt all this stuff can be implemented for aftermarket since OEMs use many microprocessors to make it all fully work.

                        All of a sudden HID seems so simple, haha.
                        Yep. There's some people trying though. But indeed, HID is extremely simple, LED offers so much more control and flexibility for lighting engineers.

                        A few unique LED optic designs are missing from this thread. Hint: Acura and Cadillac !

                          I thought I read somewhere that BMW was working on just that - the system is supposed to say, track individual raindrops or snowflakes and turn off the relevant "pixels" so that you didn't get that backscatter light, at least close to the car. Take that one step further and you could turn off relevant pixels for oncoming traffic, pedestrians, and so on and you could have "high beams" on all the time.

                          I also remember seeing a video on Audi headlights where the vehicle is supposed to detect pedestrians and flash a headlight pixel at them to get their attention to make sure the pedestrian is aware of the vehicle.

                            Yes on the latter, but I believe the first one, that can track individual raindrops, was a proof of concept tested against a "sheet" of rain. In other words, the particles to avoid (i.e. rain drops) are arranged along a curtain-like plane in front of the headlight. I'm not sure how feasible it is when dealing with real "3D" rain.

                              Right. Obviously it's an incredibly complex task. Suspect they'd only be able to pull it off for the drops within a short distance from the lens. Plus there'd be the issue with water ON the lens blurring the image. Still, if they could pull off 5-10 feet, that'd be tremendously helpful in reducing glare.

                                Ok I don't know if this has been discussed before. Why oem led setups are in range of 6500k+ kelvin? Maybe this color range offer better CRI in leds? Ofcourse currently cost is not a concern for good oem led setup. Maybe it also add to bling factor also? Cool color range offering exotic looks.
