Sagebrush posted:i think i made this point before, but it's funny to me how photographers are all about having the most perfect unaltered image from the camera, perfectly circular bokeh with a gaussian falloff, reduced dynamic range capture, zero flare, zero grain, no chromatic aberration or vignetting or pincushion or blown highlights or any other image-making artifact related: i noticed that when doing 3d stuff and the image looks off somehow, my first instinct is to mess around with the lighting and do everything “in camera” with minimal processing with photography my first instinct is “eh, i can probably fix that in post”

those new dji cameras with the gimbal built in have a lidar focus system that looks pretty neat

Sagebrush posted:it's neat, but what's the purported advantage of this over phase detection? i dont really know but it looks neat. the only thing ive seen anyone say about it specifically is for video, it lets you see different potential focus points on a top down 2d view and drag on the touch screen to manually pull focus to exactly where you need it

Sagebrush posted:here's a cool article i read about how smartphone photography works these days. there are far more computational techniques going on behind the scenes than i was aware of. obvious stuff like exposure bracketing and color correction, but also poo poo like focus bracketing, subpixel stacking, shutter coding, computational depth-mapping, ai convolution. it's nuts. barely scratching the surface here, but these guys did something kinda like that. they did something vaguely similar to these techniques on an original iphone camera's pictures to "compare" that to a new iphone https://www.youtube.com/watch?v=_gXSLJfwfwk

echinopsis posted:what I want to generate is raw camera data and achieve everything camera end by taking a different picture that article professor sagebrush posted up there talks about plenoptic cameras that basically use a bunch of microlenses behind the main lens to capture a "light field" instead of an image. kind of like taking the same photo from a bunch of slightly different angles at once, optically. he says given a light field you can calculate any possible individual image within that field, which allows you potentially to change the angle, focus, aperture, etc to a limited extent. these would be real optical changes as a post processing step, not just faking it with blur filters and crap

maybe good enough for the blurry crap photos you take

echinopsis posted:the way that values clip at the top of the range is where I kind of got inspired for the principle behind that led code of mine, but in a very hosed up way this sounds like what they call convolution in audio gear. is it the same thing?

ive got a question for u camera nerds. i want to take some hdr shots, i have a new camera on a tripod and it has a fixed aperture. i can lock in the iso at 100 the whole time, so i figure the way to do the bracketing is by taking several shots at different shutter speeds right. if my "normal" exposure is 1/20th of a second is there a simple relationship to like +1 EV being idk 1/10th of a second and -1 EV being 1/40th of a second? or is it more complicated than that? assuming there is a simple relationship im gonna guess its double the exposure time is +1 EV but im pulling that out of my rear end

echinopsis posted:have you looked to see if your camera has bracketing already? it does, but only in the otherwise full auto mode where its gonna be messing about with the iso and white balance and i dont want it to do that

well the auto bracketing function messes with both the iso and the shutter speed, which dont want to do. i want to keep iso constant. but anyway yeah i think i can do it pretty easily since it has a phone app so i just set it up on the tripod and click button on phone a couple times also unfortunately its a weirdo back to back wide angle custom lens thing for taking spherical pictures and afaict they dont make nd filters for this particular one, they make them for some of their other model of camera but not the one i have. its this one and i got it for free https://www.insta360.com/product/insta360-x3

tef posted:the insta360 x3 says it supports HDR shooting? yes but it does 3 shots and then automatically tone maps it for you in camera. which i dont want. i tried a few of these on a trip last weekend to quanzhou and only 1 really turned out any good because i didnt know what i was doing. next time i do this i'll be a lot better because ive started to figure out my mistakes only one that ended up good (warning, 183 megabyte 32 bit hdr file): https://mega.nz/file/oVAglDAK#7pD0OhKY9IlcNxkHMp2pjvJj_wZ3ctAW14cYhWX7Tj4 my main intent is to be able to load these into blender and use them both as a backdrop and as lighting data for making renders:
