I mean, the monitor is not to be set based on you camera / printer is it? It should be just right for the colorspace you use. Then why should I pay for a calibration tool, shouldn’t it be set right when I buy it? Or at least, shouldn’t I be able to download the calibration settings somewhere?

By the way.. the process is (correct me if I’m mistaken)

calibrate the screen (does it depend on the color space you’re using?) load your photo (mine are adobeRGB took froma canon 350d) Load the printer profile to see how it looks like when on paper (an agfa printer on agfa papaer)
print it out

no calibration needed for the camera, right?
Please help me out I’m full of stuff I can’t understand how to join together

thanks

You’re applying common sense to the situation, which is hard to do and unusual, and you’re very close to correct. Manufacturers want their product to fly off the shelves of the retailer. Every marketing person knows that, whether its vegetables, fruit, clothing, or monitors, bright and saturated colors sell better. Therefore, monitors, especially LCD monitors, are way too bright and saturated .

Once you get your monitor home, you want to tone things down a bit so you can look at photographs reasonably well. In general, this means reducing the brightness a bit, making things a bit more yellow-orange (reducing the color temp), and knocking back the colors a bit. You can do this is with your eyes – load an image that you know has good looking skin tones and tweak away until the image looks good. You can also spend about $150 on a device such as the Eye One display, or the Spyder Pro, and have the job done automatically. Your choice.

By the way.. the process is (correct me if I’m mistaken)
calibrate the screen (does it depend on the color space you’re using?) load your photo (mine are adobeRGB took froma canon 350d) Load the printer profile to see how it looks like when on paper (an agfa printer on agfa papaer)

More or less, though problems can creep in at each step in the process camera->Photoshop->monitor and finally Photoshop->printer. Many people have spent many hours and many dollars trying to get the kinks out, and still remain dissatisfied.

Of course there are reams of discussion of how to do just that. If it can capture or product an image, it can and has been calibrated to the max. Ignore camera calibration for the time being, and hopefully forever.

Ever notice it’s the people who stay in the five star hotels who are usually the least happy with their accommodations? You and I are happy if the apartment we rented for 40 bucks a night is free of bedbugs, and if the rats have the decency to at least stay in the walls. Ok, maybe not that bad, but close, right? Five star people, OTOH, expecting to pay top dollar for the very best, and all they can think about is how the maitre’d brought them the wrong kind of olive in their Manhattan, or that the OJ had pulp in it. It’s the same with color calibration. The harder you try, the fussier you get, and the less happy you are.

Here’s how to get good, solid three star color:

1) set up your monitor so that a few known good images look the way they should. Do a google for "calibration image" and look for something with lots of skin tones and gray step charts. It doesn’t matter which one it is, though it should be an sRGB image. Open it in Photoshop and use Convert to Profile to verify that the image is sRGB. If not, use Photoshop’s convert to profile to make it so

2) print a gray step wedge, using a one inch sliver of paper. Make sure you can distinguish all the squares, and that the squares are more or less neutral, particularly the highlights and midtones (don’t worry so much about the shadows). Your printer may work right out of the box, or as an sRGB printer. If not, adjust the color settings of your printer to accomplish this.

3) after the step wedge is set up, print your test image. Look good? Great, you’re ready to experiment with one of your camera images.

4) I suggest you stick with sRGB as your working space in Photoshop. Yes, people swear by other color spaces, and they do excellent images. These are things perhaps to explore in the future.

No, it is not set right when you buy it.

There are two things that interfere. The first is that different brands of monitors will show the same color in different ways; an untagged RGB color will look different on different brands and models of monitor, and may even look different on different monitors in the same brand.

The second is that when you buy a monitor, you are probably shopping at some place like Best Buy or CompUSA. These places are brightly lit and crowded, and you will walk past rows and rows of monitors. Which one will catch your eye? Probably the one that is the brightest and the most colorful. So monitor manufactures set their monitors to be as bright and colorful as they possibly can.

On top of that, once you buy the monitor and get it home, it will change over time. If youlook at your monitor when it is brand new and then look at it a year later, the colors may have shifted.

So no, you can not count on your monitor being calibrated correctly when you buy it–and even if it is, you can not count on it staying that way.

Well "Snaggy"? How are your color prints coming out?

Thanks for the answers, they cleared out quite a bit…
Now, I had this Idea. What if I print a few photos with the lab’s printer (the printer which is used for serious works) and then calibrate the monitor looking at them (through the printer profile of course). I thought I could use those images for color calibration etc found on the internet. Is that sufficient and possible? I’m asking just because it takes at least a week to have those prints made and money too, and I wouldn’t go without knowing if it’s possible.

I don’t think you got the whole idea yet <bg>

– Monitor calibrating is to calculate the color base on the lighting situation around where and when you calibrate the monitor. Or it has nothing to do with the photolab, printer profile. Well, a little but it’s more than that.

– Now, after you have the monitor calibrated then you know the color should match the lighting condition better… or red won’t display orange, white won’t display gray etc.. this will give you a better chance to get better print.

– Then your printer profile and photolab printer profile may and may not match your monitor profile, so there is a chance that the print won’t get a correct color display on your monitor. This mean either your calibration is wrong, the printer profile is off .. and you need to study the difference to do some fine-tuning at your end.

Once again you’ve come up with a new idea that involves actually using your eyes to match one thing to another (in this case, a print to Photoshop’s soft proof of the print), and improve the adjustment of your monitor.

Though many would say "how dare you?", my answer is yes, you can improve things this way, but there are some warnings. One is that your printer profile is not very likely to be a good match for the online printing service’s printer.

You have presumably already adjusted your monitor so that these test images have good skin tones, as well as shadow and highlight detail. If the prints are different from what you see on the monitor, then either the images are not good references after all (unlikely), or the printer screwed up (more likely). For this reason, I would not adjust the monitor based on the printed images.

It’s always a good idea to check your color settings in Photoshop. Ian Lyons has a good discussion of this for various versions of Photoshop – plus he’s got some gorgeous images
at his site, and that’s what this is all about in the end. http://www.computer-darkroom.com/new.htm

It might be helpful to note the difference between "color correction" and "color management". Color correction is, I think, getting "pleasing color", for which you don’t need any color management if you are the only person who has to be pleased. You make a print, then make a corection to make it look the way you want it and you’re done. On the other hand, Color Management is needed to get "predictable" rather than "pleasing" color especially if more than 1 computer system (including monitor and printer) is involved.

If you are just making prints yourself, by yourself, then I don’t see the need for any color management, the first step of which is calibrating your monitor. On the other hand, if you are going to have someone else(or some lab) look at or print your files, then calibrating your monitor to a known standard is needed.

You have a point. I have read somewhere that LCD monitors don’t change their colors in time as much as CRT monitors; thus it makes more sense to make a monitor model specific color profile.
