Monitor brightness while Editing photos in Lightroom

Unfortunately there is not one specific setting, it is the complete process from your camera to paper.

Please have look at this video

You can also search on YouTube for "photo editing monitor color calibration"

As a simple start you have to use always the identical conditions.

• Identical color profile for all process steps (camera, Lightroom, fulfilment house)
• MacBook always connected to power, because the screen often gets darker as soon as you run on battery.
• Lighting conditions in your room must be the same, sunny day and night with lights on will change how you see colours and brightness.

Check with your fulfilment house if they print 1:1 or if their system will do any automatic adjustments, most print 1:1 but it is better to know if they really do.

Then create 3 versions of the same set of photos.

One too dark, one what you thing is right and one too bright. Then see if the final prints match what you want to see.

Yes it will cost time and money, but at the end you get the prints that you want.

Sounds like you need to calibrate your monitor to match the colour profile you are working in, and, if needs be, be sure you and the fulfilment house are working in the same colour space.
