When the first preview appears, it looks just like it did on the camera, and then that disappears and it applies other settings. How do I turn that off?

The idea behind Color Management (CM) is to define colors in a device-independent way, that is: what you have on your screen would look (as much as possible) the same on someone else’s screen or printed on your printer. Think about the problem this way: the “most green” color on your screen can be quite different from the “most green” color on your printer, so how do we cope?

OK, I was very enthusiastic in my last entry to see my Spyder calibration device supported in ArgyllCMS. So much that I didn’t read any documentation and just typed the first command that I came across and behold, my Spyder started measuring patches. Great! However, typing the first command I came across didn’t quite produce a working icc profile.

Linux color management has the same goal as the color management systems (CMS) for other operating systems: to achieve the best possible color reproduction throughout an imaging workflow from its source (camera, video, scanner…), onto imaging software (CinePaint, Digikam, GIMP, Krita, Scribus ...) and finally its output (monitor, video projector, printer...). In particular, color management attempts to support WYSIWYG (What You See Is What You GET)) on-screen previewing (soft-proofing) ability for color work such as retouching prior to printing.

A little summary of where Linux stands as far as photography is concerned.

The issue is the color profile - the map of what color the monitor displays for a given pixel value. The standard for web graphics is sRGB, which describes a limited gamut of colors that almost any device can display. Professional imaging tools (like thos

Explanation on why some photos look washed out when published on the web.

Computers use varying types of display devices—ranging from small monitors to the latest large flat panels. Despite all of these displays, the internet has yet to set a standard for representing color and tone such that images on one display look the sa

Monica is a Monitor Calibration Tool.

Deb Richardson wrote up an interesting piece today describing color profile support in Firefox 3. The result of a color profile is a more-accurate mapping from an original set of colors to better match the intended rendering.

I'm not going to go into the full details of color management here. Basically, color management is needed because different devices conceive colors differently. For example, if you display a pure red on your computer screen, and photograph it, your camera

Today I finally got a Spyder2 Express monitor calibration kit, and calibrated my ThinkPad's laptop. I've known it to be shockingly badly calibrated (although it is an improvement over the X20), but was curious as to how much it can be corrected.

Explanation of how you can get great prints from digital photos with colour management.

To many people, colour management seems like a black art, almost the work of the devil. In fact, it really is quite simple and if you can follow the instruction manual for your camera you can certainly understand colour management.

Argyll is an open source, ICC compatible color management system. It supports accurate ICC profile creation for scanners, CMYK printers, film recorders and calibration and profiling of displays

In this page we discuss a critical step in setting up a digital darkroom: calibrating your monitor so it conforms to widely-accepted standards of image display. A properly calibrated monitor is essential for making prints that match the monitor image; it
