Can someone explain what curves are and how to use them? I know they can do anything that is on the sliders, but I'm still confused on how they work and how to use them effectively without screwing it up
>>

Curve go up brighter
Curve go down darker.

It's a tool that lets us map certain values, to other values. The line is the same thing as if you were to graph y = x, input matches output. By changing the curve, we change the output values of a given input.
In the bottom left, you have your darkest values, going up to your brightest values in the top left. The picker button lets you click on the image and add a corresponding point on the curve.

If you were move the bottom left point up, you are saying you want the darkest values to be brighter, and that's how you get that "matte" look. Same is true with lowering the top right point, gives a "matte" look to the highlights. As you move those points toward the center, instead you are saying you want a wider range of values to turn white/black.

Place points along the curve wherever you want to adjust. To add contrast, you make it look more like a slight S, lowering the bottom left quarter and raising the top right. Luma lets you adjust luminance without affecting saturation, and the individual RGB curves let you adjust color however you want. You can do basically all of your grading through just curves once you get comfortable with them.

Inverting a curve is also an easy way to turn an image negative.

Why are so many photographers retarded? Do you also need us to explain the exposure triangle for the 50th time?
>>
>>4517325
a good photographer doesn't need to use curves
>>
>>4517509
Yeah. A good photographers buys the newest sony for the incredibly accurate jpeg color and doesn’t need to shoot raw. Sorry you bought a panasonic/nikon/canon OP. Sony mirrorless is the future. Raw is for boomers.
>>
>>4517509
Bullshit.

Even high end film photographers touch up their scans in photoshop. I hate all ths SOOC bullshit. Every peak photographer you have ever liked edited their shots or had them edited by an agency.
>>
>>4517520
Skilled photographers correct everything on the camera. Selecting the correct jpeg settings before shooting is skill. Sony mirrorless has accurate colors and EVFs which allow photographic integrity and enable this skill, not touching up to match distorted memory. Touching up is dishonest and for DSLR users with no EVF. Stop being a boomer. Tiff, raw… boomer formats. Everyone smart and skilled shoots .jpg.

>Selecting the correct jpeg settings before shooting is skill.

ah so it is trolling
>>
>>4517332
Interesting, thanks for the explanation. In terms of editing hierarchy, would you edit them near the beginning or the end?
>>
>>4517528
Taking the correct jpeg on the spot is photographic integrity. Before sony mirrorless, everyone spent hours editing their photos just to have inaccurate colors and contrast.
>>
Why is the jpegcel having a melty again? Anyone know if he's ever posted any of his pics?

yes

no

>not touching up to match distorted memory. Touching up is dishonest and for DSLR users with no EVF
yes

post-processing is fake & gay.
getting it right in-camera is based and redpilled.
Shooting RAW+JPG might be necessary to work around the poor JPG engines of some cameras, but you need to record a decent image for reference, otherwise you are generating nonsense like pic related. You may as well be doing AI image generation if this fiction is your output goal.

Ken rockwell still posts on /p/? I guess p isn't dead afterall. Nice.
>>
>>4517540
Just depends on how you use them, but I tend to towards the end for more granular tuning. I prefer other stuff to set basic exposure and contrast, and C1 has great color tools, but towards the end I'll always come back to tweak.

>>4517528
It's obvious bait, safe to ignore
>>
>>4517551
Why do you lie? Sony has the best jpeg color. This was confirmed by tony northrup, and most journalists switching to sony for honesty and accuracy.

Raw is over. The century of the sony jpeg has begun.
>>
>>4517523
Can confirm. I shoot for vogue and vanity fair and we use SOOC Sony JPEG whenever we can’t use hasselblad’s natural color solution. Many hollywood films also use the sony venice cameras because they have more accurate color than arri. Sony is the color king, overall. If hasselblad made FF mirrorless or phase one pursued their trichromatic technology, only then would sony be #2.

Curves are dated tech. Modern cameras don’t need to shoot raw.

Is "honest photography" just gearfag cope in disguise now?
I've never heard a compelling argument against editing your photos outside of photojournalism/documentary style photography.
>>
>>4517559
All I ever seem to hear on board is some combination of
>I'm lazy
>I don't know how
>I can't figure out darktable
>I can't afford Lightroom
>>
>>4517562
To be fair, it takes seven years of computer science and a free month to figure out (read: fix) darktable.
>>
>>4517564
Only if you're tech illiterate and have little experience with editing in general
>>
>>4517565
Sure, thats why it needed forked into Ansel to fix its myriad problems. Go fix your spaghetti code breh.
>>
>>4517562
I mean editing your images has been an inseparable part of photography for its entire existence. It just seems ridiculous to go on and say it's wrong or bad now because of some arbitrary nonsense.
>>

>I mean artificial colors and flavors have been an inseparable part of food for its entire existence. It just seems ridiculous to go on and say it's wrong or bad now because of some arbitrary nonsense.
>>
>>4517571
So every single painting that doesn't use 100% accurate colors should be discarded as dishonest and bad? What about black and white photography?
>>
>>4517571
Your analogy is also kind of retarded. I think a better one would be like someone saying that adding salt or pepper to a steak is bad because the seasoning makes your steak taste different than it would be naturally. That the addition of seasoning to pure ingredients is dishonest.
>>

>>4517574
Ignore the literally soulless snoyboy. They’re so autistic they think scientifically accurate wavelength discrimination is a replacement for soulful color science and magazine ads and news photos are equal to art photography. Lol. Just lol.
>>
>>4517585
Dang. That's sad he needs to rely on objective metrics that scientists tell him are good when photography is an almost entirely subjective practice. I guess he is soulless.
I bet the poor guy can't even appreciate color stretching.
