You might have come across of magenta lines or areas in your night shots at high ISO which are called amp-glow.
Final image with some basic adjustments in Lightroom.
100% crop. Before and after with exposure set to +3,68
With the Adjustment Brush and the settings as shown below I just painted over the critical areas. Make sure that Auto Mask is on and temporary set the exposure high, around 3,5 to better see what you are doing.
This are the setting which I figured out worked best for my camera. I think it should be a good starting point for other models too.
Removing Amp Glow is easy to fix. Once you figured out what works best for your pictures you can save a Lightroom preset and apply it whenever you need.
I hope this was useful. Please keep in mind that I can not do all this for free without your help. If you would like to support me you can do this by purchasing my images, posters or my book. Thank you very much!
