you can download the curve here.
+ this curve doesn't work well with dark photos!
to install your curves:
- if you're on a mac, open the photo you want to edit with photoshop, click on command + m to open the curves window, beside the option bar "presets", click on the little image of a drop down menu, click on load presets and open the curve in your downloads folder / desktop.
- if you're on windows, do the same thing above, except once you open the curves window, click on the load button, open your downloaded curve and click on 'ok'.
