Hi, I bought custom preset long time ago and I like it very much. However it has one problem. It changes the yellow color to almost pink. Even when I set all setting and colors in Lightroom to default (except disabling the preset), it does not change. Is there any "hidden" option to edit the preset? Thank you!
Presets are nothing but pre-settings. They set sliders and other options that you can also set manually. So no, there are no hidden things in a preset, but it can be difficult to find all the possibilities. Check if the preset did not apply a different profile. That is one of those things that you can easily miss.
You can select the default profile and then update the preset with the current settings if you do not want the preset to apply that profile. You do that as follows. Take an image without any settings. Apply the preset. Change the profile back to what it was. Right-click on the preset and choose 'Update with current settings'. Select only the settings that the preset actually changes in the dialog that follows!
