for xmas i’ve gotten my son a 550d

it was $250 and it’s come with a tripod and that 18-something lens which is poo poo but he can borrow some of mine

what I love about this day and age is the low barrier of entry. like bloody says, can still take a great photo. biggest bummer is the lack of low light ability but still, he’s only 12, he’s so fortunate to have this kind of thing to play with





yps: at a beautiful cottage with gf for weekend but I have zero ability to take interesting photos lol. i would love a decent photographer to show me their workflow because it depresses me a bit how I can’t do something with this as beautiful as it is 😒

i need to think, how can I somehow put the viewer there and make them feel idk something

yah. i have the gear but not the skill to take good photos

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

and meanwhile cg artists are like gently caress yeah, give me all that poo poo, i want hexagon bokeh, donut bokeh, flare everywhere, halos and ghosts, tri-color chromatic aberration, ultra grainy, film scratches, motion blur, contrast blaster, micro depth of field, hunting for focus, just give me every poo poo thing that cameras do to gently caress up an image. because that makes my cg look realistic

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”

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

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.

https://www.dpreview.com/articles/9828658229/computational-photography-part-i-what-is-computational-photography



in essence, good smartphone cameras (iphones, google pixels) don't necessarily have better optical hardware than other phones. they take the same relatively crappy input that other phones capture (physics is physics) and do extensive computational image synthesis to make the output look great. most of the improvements in phone camera quality in the last few years are just from having enough ram and processor power to pull this off.

i wonder what would happen if you combined these techniques with a full-frame sensor and a big lens?

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

what I want to generate is raw camera data and achieve everything camera end by taking a different picture

i want to play around with individual computes afterward

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

ok that’s interesting. the use case I wonder about is lens on a the back of a phone.

and I always wondered how that lytro camera actually captured the info. very interesting

thanks for sharing


this stuff is interesting from a purely interest sake perspective. in real life i’m more interested in taking better photos so that one day people think i’m ok 😩

they won’t think youre ok until you get that fancy plenoptic camera

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

I really like the idea of 3d luts because they should in theory be able to take the digital data, as long as it’s not clipped, and replicate the way film deals with highlights, including if it creates colour shifts. but if there are light bleeding effects in film which I believe there are, that’d require a bloom like filter which I am still in search for (a bloom filter that works with high dynamic range stills and has a shoulder not a threshold)

I enjoy the post shooting process as much as shooting so I shoot raw, straight to jpeg would take half my enjoyment away.

and whenever I take any raw image into photoshop or affinity photo it makes me “develop” it before using it so you can’t really play around with the high dynamic range, at least well maybe Im just too stupid to work out how to.

this sounds like what they call convolution in audio gear. is it the same thing?

when I was using the 100mm I never had the sense that I was standing away from the person, we just weren’t close, but this is definitely speak-up territory.

i’ve got the loaned 85mm to compare it to at the moment, but if I discover I prefer the 85mm i’ll be gutted.: not wanting to face purchase regret i’ll probably just avoid this conclusion

it’ll come down to, are the potentially better shots worth the extra difficult it working with the lens? time
will tell.




and mates I am excited to play with the flash. I reckon I need a filter to yellow/orange up the light because my primarily intention is for outdoor and white flash with outdoor light apparently looks like poo poo and understandably too.

you know what you must do now. buy a medium format camera to go with your long lens

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

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

the insta360 x3 says it supports HDR shooting?

albeit in 360 mode, not single lens mode

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:
