skimage make light spots lighter and dark spots darker

You now still have the option to reduce the opacity of the Curves adjustment layer if needed, to decrease the severity of the lightening effect you've applied.What this will do is apply the curves adjustment only to the darker colours in the image. Then in the Blend If section, leave Blend If set to Grey, and drag the white slider for This Layer to the left.

Set the Blend Mode under General Blending to Luminosity, you'll see a bit of colour pop-back into the image where it was pulled out by the curves adjustment in step 3.Select the Curves adjustment layer and choose Blending Options from the Layers panel menu.The entire image will start to lighten up as right now all the pixels will be affected. Ive been on Meladerm now for 2 wks w/o much change. The melasma has lightened a bit but the area under my eyes (on orbital bone) is much darker now Ive been trying all the non hydrquinone products w/o results. Note: you can also use the on image adjustment tool (the icon with the point finger), and click on it then drag upwards in a shadow/dark area of your image, this will automatically add a new point on the curve.įocus on the shadow areas of the image and ignore anything that happens to the light parts of the image as you are adjusting the curve in the Properties panel. Im 8 weeks post 4th PicoSure focus treatment Ive had 4 picosure focus treatments for melasma around eyes. Next in the Properties panel, add a point to the curve and move it upwards.Choose Layer > New Adjustment Layer > Curves (you should see a new adjustment layer added in the Layers panel above the Background).Here's an example (not the best pic I know, but hopefully you can follow along): There are a lot of different techniques you can use - hopefully other people will share their techniques as well, so you get an idea of the different approaches.
