Listen buddy, we all got problems!
Does it even work though?
Instagram is overflowing with that sort of content.

Ad companies have started to incorporate more disabled , older and different bodied people in their campaigns and it might just be too pretend they care but it has had me noticing ads on the street for the first time in years.

going through my grandpa's old camera gear and he's got some interesting stuff



left to right: an old kodak bantam rf and a ton of lens/filter adapters and filters for it. takes kodak 828 film which i'd never heard of before.

a viewmaster personal stereo camera. shoots 69 (nice) stereo pairs on a 36 roll of 35mm. he's also got a huge stack of viewmaster.. discs? of photos he took back in the day. really neat imo.

a waltax junior. japanese camera from the 50s, uses 120 film.

olympus om-1, plus a MASSIVE telephoto lens for it.

i dunno if i'll ever use any of it, but i'm taking it.

my grandmother has one of those kodak disc film cameras in her office closet and it makes me lol when I see it

alright skipping 81 pages of discussion to ask dumb questions:

i've got an iphone and it saves photos as .heics with the p3 colorspace. i've been pulling these into gimp do do some work (in this case i'm loving around with making some pixel art) and it pops up with a dialog about color spaces, which i always used to ignore.

for web poo poo should i make sure it's all in srgb? i found out pretty quickly that a bunch of the colors in the images i'm importing aren't in srgb space.

2nd part of the question: gimp has 4 ways to do the conversion. by eye it looks like the relative and perceptual methods add a lot of saturation to the image, whereas the saturation and absolute methods look almost identical to the original image. it's just confusing to me because the default method (relative) makes some pretty major changes to the image, whereas the saturation and absolute options appear to do a much better job at making an image that looks the same.

1st part: DCI-P3 is the color space that is used for digital theatrical projection. display P3 is a variant of it apple developed for computer displays. sRGB was the dominant display gamut for quite a while but it has been basically replaced by display P3 as a de facto standard and it encompasses sRGB. most older monitors and devices are calibrated for sRGB and can display most of its gamut (usually at least 98%); display P3 is a newer wide gamut standard that most modern (say, manufactured within the past decade) displays use. most of them can display most of if not the entire gamut. sRGB native devices can display P3 content, but it'll likely look a bit saturated and the colors will be dithered to whatever the color management system thinks its closest match is. but really that's typically not something most people will notice

therefore to answer your question about whether you should target sRGB: no.

imo you should target display P3 since most modern devices use it. the intention behind the standard is to ensure that content will look perceptually the same across mediums. even older ones not capable of displaying the entire gamut can use its ICC profile; most mobile devices made within the past decade do and every apple device regardless of form factor does as well. this includes older devices with sRGB displays running newer OSes

2nd part: color translation is complicated. that's partially why they are trying to standardize a single color space! my advice is to not worry about it and go with what you think is the best representation of your image.

that said the saturation and absolute methods look closest to the original image because they are really not dithering anything. absolute means that it is just using the next closest point in the color space. when you're mapping a narrow gamut to a wider one (i.e. sRGB -> display P3) this is usually ideal as the entire narrower space is encompassed by the wider one; all of the points can be accurately mapped. conversely when doing the opposite, colors outside of the output device's color space will appear too saturated. since your display is likely using P3, it looks fine

the saturation method is using color intensity rather than hue to approximate a "correct" representation of the content. since you're mapping a wider gamut to a narrower one, the main way that difference becomes apparent is through color intensity since they get clipped to the outer boundaries of the gamut, because that color can't be accurately represented in the output. the software simply varies the chrominance instead of mapping points within the color space to approximate what the output should look like

thanks i think that makes sense. this all came up because i was just rolling with keeping the display p3 color space in gimp, but when i was sampling colors to generate my palette it was doing weird stuff in the color picker (like negative values for rgb, which makes sense after i read up on the color spaces). so i wasn't sure whether i should strive to make my palette fit within the srgb space or if i should just say gently caress it and use the bigger space.

i just went ahead with converting to srgb and sampling colors after that, but it may make sense to just keep the original profile so i can mess with a wider gamut of colors if i'd like. the only hitch is whether or not any of the other apps i'd use to edit the pixel stuff would support using something that's not srgb.

anyway, here's the result:



i'm making a pixelly background for my web 1.0 site i'm slowly working on

yeah i'm sorry if that might be a little confusing but it's a pretty complex subject (if you have questions just ask). really mostly everything these days uses P3. most of my android devices use it and i think windows 10/11 do by default as well, but either way chromium based browsers (so chrome and edge) will also use P3 even if the system does not. so for web content in 2023 it is best to use P3 i think

that said it's not like sRGB is going to look bad, there just aren't as many colors to use. when talking about the differences between sRGB and P3 that usually manifests in reds and greens. the tone reproduction curve (gamma) of display P3 is intentionally the same as sRGB so overall contrast should remain the same, which other than saturation is the main difference people will notice

just use web safe colors and dithering

i'd have thought srgb was still pretty dominant for web/desktop even if p3 support has expanded.

colorspace chat had me nervous about an image i just turned in as a book cover, but they said they were fine with whatever ludicrous 25 megapixel bullshit I turned in in 16-bit TIFF in sRGB so I guess itís still fine. color representation was not a huge concern of mine for this, but it does entertain me that chromium browsers show the .jpg and .tif files in google drive with different color casts. the tif matches the lightroom display so ??? but at least nobody complained. i'll be interested to see what the cover looks like when it's printed versus what i see on my desktop display/s and phone.

for images produced with desktop apps it probably still is. i know at least older versions of adobe tools will convert to sRGB when using the web export options, i'm not sure if they still do (i don't have a sub anymore). but anyway, i was pointing out that the expanded support is pretty significant: that's including most new-ish mobile devices, most 4k tvs, all apple laptops from the past decade or so (plus other manufacturers i'm sure) and a whole lot of monitors ó a pretty significant chunk of web traffic. eeyo was asking if there was a reason to convert their stuff to sRGB instead for web use, and considering that support, i generally think that there isn't

i didn't realize they were talking about making pixel art though. i'm not really sure if that changes my calculus, but imo the wider gamut is worth it for photos at least. especially if your camera takes them natively in wide gamut as eeyo's iphone does
