Hello, I have a problem. Normally I shot in RAW, edit the image, save a jpg (with sRGB Color space) resized for an on-line printing service and another jpg in full size and resolution.
Recently I bought a Spyder express monitor calibrator, so I have my calibrating profile called ''spyder2express.icc'' and I configured in windows xp my display to read this profile.
I edit a raw file with lightroom, but when I export to jpg and I look it with another viewer it doesn't look like the edited raw file, but it is mure saturated and different.
The same thing happened with Photoshop, looking the photo with the software is ok, but the jpg looked with xp viewer, ot faststone capture, or irfanview the jpg is different.
I'm sure that the profile is sRGB, so why this difference?
Is there anyone who can explain me what to do, and how to configure my computer?
Many thanks in advance
What you're seeing is the difference between a color managed application (LR and PS) vs. non color-managed applications. There can also be small differences in how a JPEG appears when viewed in LR vs. its rendered RAW version, but these generally aren't noticeable unless the monitor profile is off.
Are your prints coming out all right?
Monitor Calibration %26 Lightroom 2Well but .... if I calibrate my monitor, and I configure my display with this profile, I imagine that every application is ''filtered'' by profiling, so I imagine that jpg seen in Lightroom and PS, and jpg seen in xp image viewer should be the same.
No?
Yes, it's completely logical one would think that, but it's not so. At the same time, a JPEG in sRGB should be fairly close in managed and non-managed viewers.
The image will be displayed correctly by any colour managed application. If the application you use to view a file is not itself colour managed then whatever profile is embedded in the image will not be honoured. In the case irrespective of wether your monitor is calibrated or not the image may look different. I don't know wether the app you refer to is colour managed . If you want to check if your browser is colour managed (firefox and Safari are both capable of colour management then have a look here.
Just to clarify above the explanation by the others. Monitor calibration consists of two parts. One part is the calibration of the gamma curve. Gamma basically corresponds to contrast. This part is picked up by all applications and is handled by a correction table (called a LUT for LookUp Table) that is sent to your videocard. The second part is the correction for the gamut of your monitor. The gamut is basically the range of colors it can display. The gamut is determined by the actual wavelengths of red, green, and blue your monitor uses to mix the colors. This is different for every monitor out there and often quite different from sRGB. Some monitors have a much narrower gamut (most laptops) and some have a much wider gamut (the wide gamut displays that lots of people have now made by NEC, Samsung, Dell, etc.- my guess is that you have one of these). So even if you use sRGB, you still have to correct for this in order to display the right color on such displays. ONLY color managed apps do this. Lightroom is color managed as are many other apps such as Photoshop, Firefox 3.5, Safari, etc. However, many apps on windows are not, such as internet explorer, image viewer before vista, etc.
So this means that, if you are to share JPEGs on the net or at least with other users (using non-calbrated viewing devices) you should not use the color profile from the Spyder, but rahter standard sRGB as defined by the computer?
The color profile from the Spyder is for viewing images on your computer it is a ''monitor profile'' and is specific to your monitor. If you change your monitor then you would need to create a new profile. It allows you to view JPEG, TIFFs, PSD etc which have a color space of sRGB, aRGB, ProPhotoRGB etc with true colors.
If you wish your JPEGS to be viewed by others on the net etc then you need to export the files from LR using sRGB color space, otherwise if their monitor is not profiled they will not see images with?aRGB, ProPhotoRGB etc color space correctly.
Yes, sRGB is the one. It's the best bet for web and e-mail whether or not your correspondents/viewers have properly adjusted monitors.
