This video explores increasing or decreasing contrast using a tone curve.
- [Instructor] The Curves dialog box is a powerful tool…for adjusting the contrast and the color in an image.…As with levels, curves can be applied non-destructively…as an adjustment layer.…So I'm going to come to my list of adjustment layers,…or I can just click on my Curve icon…on the Adjustments panel, and here is my curve.…Now I have currently a 10 by 10 grid.…If you don't see a 10 by 10 grid, Option or Alt + click…and you can toggle between a four by four or 10 by 10 grid.…
You can see that the curve, currently a linear curve,…is superimposed upon a compressed histogram…like we saw in the Levels dialog.…So you add a point to the curve by clicking on the curve,…dragging up to add light, dragging down to remove light,…this being an RGB image.…If you want to remove a point, drag it off the grid.…You can edit a curve with up to 16 points,…though typically you only need one or two.…
There are a number of useful presets.…If I choose Strong Contrast, we have what's referred to as…an S-shaped curve, where light is being added…
