Colour correction
Hi all Just been asked by a wedding photographer to do some colour correction work. Can anyone tell me, do you do this by eye or is it a precise technical process? Also, should I be callibrating my monitor to any specific value? (As you can tell, I flying a bit by the seat of my pants on this one. Grateful for any advice. Best wishes Chris |

Re: Colour correction
I have been negligent about it, but calibrating one's monitor is said to be very important for the sake of consistency from one computer to another. What I do is use the gray black and white droppers in either the levels or curves box to establish gray (preferrably) or black or white. I will then if still necessary use curves to adjust the individual channels. Depending on where you live, you should be able to find a book at a local bookstore that deals with color correction in photoshop. If you have access to photoshopuser.com you search for more information. ADOBE PHOTOSHOP STUDIO TECHNIQUES by Ben Willmoree has extensive chapters on color correction. Hope this helps. |

Re: Colour correction
Calibrating your monitor is important as different monitors will vary in the actual colors that you will see. Take a look a several monitors playing the same image in a computer or TV store, and you can see a big difference. But you can get around this by using the info palette in photoshop, and can also do many color adjustments by using the eyedroppers in the curves or levels adjustment windows to adjust for black, white, and gray levels. One thing about calibrating though, is that you can also calibrate your printer and scanner, as well as the monitor, and set up profiles so that all devices will see and display/print the same colors. At the very least though, you should use the adobe gamma calibration that is installed when you install photoshop. You should be able to find it in the control panel, and there is plenty of information on the web as to how to use it. ![]() |

Re: Colour correction
I have a little device called a huey, made by Pantone. It costs around £50/$80, and sits in front of your monitor checking ambient light. Once a week or so, you hang it on your screen and it calibrates it. Well worth the price! |

Re: Colour correction
If the colour correction needed is the same on all photos, it would be worthwhile setting up an 'action' so you don't have to spend ages on each photo. Just remember, work on copies not the orginals, incase something goes wrong. |
