hey someone tell me why the sensors in digital cameras dont have a set up where every second pixel had a neutral density filter on it, and using the pair to increase bandwidth and capture far more information from the scene. like this idea can't be new, somewhere someone has experimented with this, and there is a reason why sensors in cameras dont have it. its the coolest most baddass idea for creating true high dynamic range images. so why doesn't it work

um no it would be equivalent to taking a photo and then taking an identical photo with indentical settings but with a ND filter over the camera, and then using those two images to create a single image with a higher dynamic range. use the filtered one to recover information in blown out areas in the non filtered one but this is done by having every second pixel on the sensor having a filter on it

echinopsis posted:um no Wouldn't that just cut your resolution in half? I don't know much about how sensors work but it seems like all the pixels are currently used to render an image. What you're suggesting sounds more like auto hdr bracketing in theory.

It shouldn't cut resolution in half if you take every second pixel and every (2nd + 1) pixel and used [algorithms] to decide the exposure of both pixels. I suppose the best way to say it is, it would be a full resolution photo with "half resolution" exposure (or something like that?). hope and vaseline posted:What you're suggesting sounds more like auto hdr bracketing in theory. I think that's basically it. Given what some people say about megapixels not being important, I would take that to assume that even though you're basically taking two (total megapixels/2) photos, you should still be able to use the details of all of the megapixels for the final photo.

Just make a sensor that has a thousand stops of dynamic range and boom problem solved.

xzzy posted:Just make a sensor that has a thousand stops of dynamic range and boom problem solved. You jest but I think this is the actual answer to echi's question. It's probably unfeasible to make sensors the way he described (afaik sensor wafers are already extremely difficult to make which is why full frame cameras are still $2k+). So it's literally easier and cheaper to just improve sensor dynamic range than it is to add special minuscule ND filters on half the pixels.

surely thats a goal though. like no necessary reason why sensors have to be similar to film as far as dynamic range goes I deal with proper high dynamic range images coz of what is produced with 3d software is hdr. the cool poo poo you can then do with it drat

Doesn't film have a greater dynamic range than even full frame sensors? I remember reading that somewhere but I'm not sure how true it is.

it probably has a better profile or curve when it comes to blowing out but yes come on make them better or add a filter to every second sensor

 This whole situation seemed kinda dodgy and gritty to me, so I figured a B&W treatment might be fun!
