Editing on your laptop?
The benefits of editing on a desktop computer is that you can properly calibrate your screen, with the computer in the same location and usually the same lighting conditions. Whereas, each time a laptop is opened the screen will be at a different angle, and chances are you may be taking it to various locations and in different lighting conditions.
There's nothing more frustrating than making a print and it's come out darker than the screen - it just feels so disappointing and we've all been there. The first step to solving this problem is to turn down the brightness to around 45%. We are so used to seeing our screens on maximum brightness, and to begin with 45% will seem so dark, but just go with it and see the results.
