Curves black eye dropper turns image white? Auto color turning image white?

[Jokellypff]

I followed a tutorial with curves and the curves eyedroppers that made me go into properties and change some settings. Specifically the black eyedropper settings. Ever since then every time I use the black eyedropper in levels or curves or if I use auto color, auto contrast or auto-tone my whole image will turn white.  Is there a way to reset these options in photoshop?

If I delete photoshop and reinstall will photoshop reset to its original settings?

I'm so frustrated with this. I can't find the tutorial I followed either so as to undo whatever it said I had to do....

Try open level or curves adjustment panel and click on the eyedropper on the right below optioons then enter the values as wanted…

I'm having the same problem and am a VERY experienced user (been a PSer since '95) - any fixes for this? I use the levels eyedroppers to color correct my images - or I did, anyway. 😞

Can you specify exactly which settings?
