Warning: my printer turned skin tones green, and a $12 bulb fixed it
I was printing wedding photos at my kitchen table in Tulsa two weeks ago and the bride's skin came out looking like a lime. I checked everything, profiles, paper type, the whole list, then a guy at the local camera store asked if my desk lamp was daylight balanced. Swapped in a $12 daylight bulb, redid the soft proof, and the prints matched the screen on the first try. Has anyone else had a light source throw off their whole view, or am I the only one who missed that?
A bulb can change how colors look to your eye but it doesn't change the actual pixel data that goes to the printer. Your file was the same before and after, so the real fix was probably the soft proof settings you redid, not the light. People blame lighting all the time when the truth is their monitor was off or the profile was wrong. If that bulb really fixed it, then you were editing by eye under bad light the whole time, which means your screen is still lying to you in the dark.
