You're killing your blacks. I've seen a lot of photographers try to achieve the "light and airy" look by bringing up their blacks. "Black is bad, right? Black makes things dark, so if I want LIGHT, I have to get rid of my blacks!" Exposure and shadows make things dark, black adds depth and dimension. Let me say it louder for the people in the back: BLACK ADDS DEPTH AND DIMENSION!!!
Have you ever seen (or edited) a photo and it's just... flat? It can sometimes be the contrast but 90% of the time, it's because the blacks have been stripped out of the image. The photo looks flat, slightly hazy, and almost like you're looking through a white cloud. When you remove dimension, you're left with a flat, blah photo that's pretty but not wow.... PUT THOSE BLACKS BACK IN, BABY!!!!
Blacks aren't the enemy, they're the misunderstood, unsung heroes of dimension and pop! If you want that WOW FACTOR, pop in those blacks, my boo. Give your image what it's asking for and make it jump off the screen! *Shoutout to spell check for annoying me everytime I tried to spell "dimesion" without the n.
