I do all my photos enhancing on my home PC using Photoshop. I do all the contrast, colors, etc., save the photo and that's it.
I go to work, open that same photo (just to view it) and it looks either too dark, or too light. How do I set my monitor so that when I do Photoshop enhancements I get the same results. I don't want to enhance a photo and then print it and have it look different. How do I keep this consistant? Do I set the same Brightness on my monitors? How do I know the photo will look good when it prints?
Marina, welcome to the world of calibration! You are expeiencing the reality that no two monitors look the same given the same data, and monitors rarely givve the same colors as printers when both are fed the same digital information. I won't delve into the technical reasons for this - it's just a reality.
What you need to do is calbrate your monitors and printers, using equipment from Colorvision (the Spyder) or Gretag Macbeth (Eye-One) or something similar. These are software and hardware suites that measure the actual colors being displayed by a specific monitor and then altering the computer's internal profile for that device for future use.
That is, there is a table in the system that converts the signal 245,0,150 to some shade of purple (245 red, 150 blue). But that same 245,0,150 might cause another monitor to display a different color purple, again, due to a variety of factors. The calibration device is placed over a spot of this purple on one monitor, and it reads the exact shade being displayed. It can compare this to the other monitor and put a correction in the "translation table" so that next time, the second monitor will output the same shade of purple as the first.
I hope that made some sense - you may want to look into some books on the subject, like Real World Color Management by Bruce Fraser.
