For the most part, you'll be using Additive colour theory in Photoshop. In this lecture we'll learn about the RGB colour space and the basics of colour correction.
I am getting my psychology degree and never understood additive versus subtractive color mixing in perception until this video! None of my psych professors ever made it this simple for me. Thank you!!
I have a makeup artist test for film tomorrow morning and I was really struggling with the additive and subtractive color theory portion of my study guide. This helped so much! Thank you!! So easy to understand than just reading a textbook on it. Thank you, thank you, thank you!
That section relates to doing colour corrections on photographs. The camera's Auto White-Balance saw the Magenta in Becky's sweater and incorrectly assumed that the image had an overall Magenta cast, so it added some Green (the opposite of Magenta) to try to colour correct it. This gave us an image with a greenish cast (hence Becky looking a bit greenish/sickly). In Photoshop, with the image in RGB you could use the Green channel to subtract some green and fix the image. If, however, you were working in CMYK (maybe preparing the image for printing in a magazine using a commercial press), you wouldn't have a Green channel, so you'd have to go to the Magenta channel (the opposite of green) and add some Magenta (the opposite of removing some green) to fix the Greenish cast. This shows the inverse relationship between the colours in the Additive (RGB) and Subtractive (CMYK) colour spaces.
on the right, where the layers are, you can see that the blend mode is set to "linear dodge/ add", if you do that with all the layers, you get this effect
Három fő szín létezik: piros, sárga, kék! Ezek a színek nem keverhetők ki más színekből! A zöld a sárga és a kék keveréke. 1.42- nél szereplő ábra rossz, hamis. Piros és zöld keverékéből nem lesz sárga, esetleg barna! Kék és zöld keverékéből nem lesz halvány kék, esetleg kékeszöld ! A piros és kék keverékét véletlenül eltalálták, az valóban lila.
Szia István. A művészek előválasztásaira gondolsz (amit néha átlátszatlan festékeknek is neveznek, mert ez magában foglalja az átlátszatlan festékek keverését), és valóban igazad van abban, hogy a sárga és a kék festék keverésével zöldet kapsz (és a vörös és zöld festék keveréke legyen különösen vonzó). Ebben az előadásban a fényképészeti primereket (más néven "adalékos" primereket) vizsgáljuk, ahol a tiszta fény (különböző elektromágneses frekvenciák) összeadásával foglalkozunk, nem pedig festékekkel vagy pigmentekkel, amelyek kivonnak (elnyelnek). ) fény. A piros és a zöld fény kombinálása valóban sárga színt eredményez. Piros és zöld festék biztosan nem. Hi István. You're thinking of the Artists' primaries (sometimes called the Opaque primaries, because it involves mixing opaque paints), and you are indeed right that mixing yellow and blue paint will give you green, (and a mixture of red and green paint will be particularly unappealing). In this lecture, we're looking at the Photographic primaries (also called the 'Additive' primaries), where we're dealing with the adding together of pure light (different electromagnetic frequencies), rather than paints or pigments, which subtract (absorb) light. Combining red light and green light will indeed give yellow. Red and green paint definitely will not.

As a first-year graphic design student, this was incredibly helpful and dug me out of my pit of confusion ;) Thank you so much!
If you liked this lecture, here's a great video by Captain Disillusion that takes a deeper dive: th-cam.com/video/FTKP0Y9MVus/w-d-xo.html

Wow, I was curious on printer colours, this I found this. Great explanation!
i always wondered this so googled it and ended here......... very interesting lecture... thank you !
That was great. Thank you.
This has been extremely useful! Is the video for an online course?
You're a great teacher. Thank you 😊
Awesome video, helpful for intro psyc too!
Excellent video! Surprised no one’s criticised it yet
They know better...
@@GregDanbrookeLectures mhm. Not everywhere though, people that deny evidence about colours exist, just like flat earthers
Amazing lecture
Great demonstration!
thanks! grateful for the overview, admit i started getting lost around "Becky".

Wow! How did you achieve to create the effect un photoshop?! 😱
on the right, where the layers are, you can see that the blend mode is set to "linear dodge/ add",
if you do that with all the layers, you get this effect
@@xx1simon1xx thank you so much! I’ll try to do it
@@mscximenacuriel4491 Linear dodge works on black. If you want to simulate the look on white, try Linear Burn.
Shout out to those fellow no-sleep art students out there!
haha me right now!
i wanna go to the app can somone send me link
