I can finally use curves!! I am so excited because I have been trying to find a way to use curves without Adobe Photoshop for around a year by now. Thank you so much to Snapseed for finally releasing their curves!
This is a really great Photoshop tutorial on how to use curves and it was super helpful because it explained both the RGB curve and curves for separate colors. This video does contain some information that isn't applicable to the Snapseed curves because you can't select colors, but overall, it was really great!
Here I tried out using curves. It definitely takes a bit of getting used to and sometimes is easier just to use the normal adjusters, but I like using curves because it's a great skill to have! I used a photograph of my dog and lightened it up a bit, but the curves can also be used to change the colors like the red and teal photo
