When you look at colors next to each other, they blend. This is the foundational knowledge of the Pointillism movement as well as how modern printers work. Because 99.999% of people don't need to zoom super far in pictures their camera phones take and 99.999% of people who do need to zoom just use real cameras, you can save storage space in the phone and simultaneously make a shitty photo look good by using the principles of Pointillism and just having people's eyes blend the colors naturally. There's no big cover-up here, camera phones record quite a bit and the lack of a decent zoom is only going to affect people doing nature photography of dangerous animals or working as spies — both of which, again, use real cameras for their jobs.

Pic related is a classic Seurat painting that demonstrates Pointillism, printers, and JPGs. Back away several feet from your screen and let the colors blend, then look really close and let them separate.

Seurat, like the painter

I give you egghead discount

froooooo knoows pho to

>PSA: dont save as JPGS.

so how do i save as anything better?

Okay, /p/ here, I actually have extensive training/experience in photography so listen up here welps.

Tiff, tga, jpg, png (to some extent, png is absolutely fantastic for vector art), gif are all PIECE OF SHIT image filetypes because they are usually made with the sRGB colorspace. For evidence, check the image. The solid part represents sRGB (the colorspace widely used on the web) and the outer wireframe represents Adobe RGB (or RGB 98). As you can see, the color space of sRGB is much smaller than the colorspace of Adobe RGB. This basically means that you're never going to get the same color fidelity out of sRGB as you will with Adobe RGB.

Now, of course some of the filetypes above are more than capable of supporting Adobe RGB, but here's the problem: images don't always look the same on every monitor you fucking morons. Why? Well, other operating systems have different ways of displaying color, as for why that is go talk to Apple/Microsoft/Linus Torvalds and ask them why they can't get along when it comes to color. Additionally, browsers use the sRGB colorspace for compatibility. So, to help out the average idiot user who doesn't know how to convert colorspaces, it becomes much more useful to have simple, ubiquitous devices like cameraphones shoot with compressed, widely used (and therefore highly compatible) image types like jpeg and save the recorded data using the sRGB colorspace. Using this method, the image is going to look EXACTLY THE SAME on every monitor and every device.

Think about this, you take a picture of yourself and send it to your grandma. Then she says that your face is absolutely pasty white and wonders if you're doing ok. Of course you probably fear the sun (just like I do) but you just sent a picture to your grandma over the internet using the Adobe RGB colorspace and her browser/image viewer/whatever downsampled it to sRGB for compatibility. The sRGB colorspace makes sure this doesn't happen. To further explain, if you try to "enhance" the colorspace of an sRGB image, you're basically a fucking moron becuase the sRGB colorspace was, again, not designed for fidelity but rather compatibility.

Furthermore, cameraphones have extremely small sensors. If you even believe for a second that a small sensor is going to get anything close to good color, you're fucking insane. This is why real photographers actually use DSLR's, not because they want to look like a prick but because that's really the only way to do it, unless if you wanna whip out even more bulky and expensive equipment like fucking view cameras. DSLR's have much larger sensors and therefore have much more colorspace fidelity.

Additionally, real cameras are able to shoot in RAW formats. This means that when shooting a picture, the output is an EXACT duplicate of the data attained by the sensor. No downsampling, no resampling, no colorspace fuckery, absolutely nothing happens to the image quality in between shooting and storing. Usually this functionality is not present in cameraphones because honestly there's no reason to shoot with raw with such a shitty sensor. Also when using RAW, you can use tools like Adobe's Camera RAW plugin which attaches metadata to a RAW file so that the image can be altered without fear of resampling the original image.

Even still, cameraphones are just completely fucked because they don't have a shutter. That's the "single lens reflex" or SLR in DSLR (Digital SLR). This means that you're going to have to trust an algorithm to judge when to start taking recording data and when to stop recording data. Sometimes things are moving too fast for the camera to pick up, which will cause vertical tearing (pic related). Sometimes the signal to the processor to stop the recording of data can get caught up with other processes and the signal to stop recording data comes late. In photography, just like in computing, every millisecond counts and being late or early can really fuck things up.

>b-b-but muh megapixels

MEGAPIXELS ARE WORTHLESS unless the image actually has a good colorspace.

man… I've owned my DSLR for over a year and have looked into various photo websites before for tips, but I have never heard about this difference between sRGB and Adobe RGB before, aside from some people saying "it makes no difference"

I'm going to have to experiment with this shit now

>images don't always look the same on every monitor

display calibrators can help overcome that. I've ordered prints before and the colors were thankfully just right
