Check out this image by Jeff Schewe from wikipedia. It's a 2D slice of what's really a three-dimensional space, but it makes the basic concept clear: So: sRGB is a subset of AdobeRGB, which is a subset of ProPhoto RGB. You can also see how ProPhoto RGB extends outside of the curved shape which represents visible colors. And you can see how AdobeRGB is a ...

sRGB is the most common color-space used anywhere. AdobeRGB is a wider color-space which can represent more colors but with less precision when looking at the colors which overlap sRGB. Neither color-space really matters when shooting RAW. The embedded thumbnail or preview within a RAW file may be affected by the choice of color-space though, so keeping ...

sRGB is the default color space, which is way that RGB values translate to actual colors. In RGB, (255,0,0) means "full red", but what exact color is this going to be usually depends on the display or printer that's used for the output. As this is undesirable for professional purposes, people employ color management to ensure their idea of "red" will display ...

It's just the values from the sensor, which is a (mostly) linear counter. The different photosites on a Bayer sensor have different colored filters, and the value for each site represents the light which gets through that filter. The name "RAW" is meant to convey precisely that the values are simply that "uncooked" reading. In a sense, then, the RAW file is ...

If everything is working correctly, the difference should be subtle and you shouldn't generally notice a big shift. I have a suspicion: You may be working on a monitor which is not capable of rendering the whole Adobe RGB gamut. In this case, out-of-gamut colors are clipped or approximated (perhaps poorly). When you convert to sRGB, the colors are mapped ...

Actually, #E58C4E, if you mean the web color, is defined to be in sRGB. However, if you didn't mean that particular convention but rather "red:229, green:140, blue:78", it's a different matter, because the extremes (the "primaries") of each channel are different in different color spaces, so those numbers actually do represent something different in each ...

If you have a Mac, you can visualize differences between color spaces in 3D - run ColorSync Utility, and select a large color space (like ProPhotoRGB or AdobeRGB). Then click on the arrow at the upper left corner of the plot, and select "hold for comparison". Then select a different space to see it plotted on top of the other one, you can rotate all ...

To add to @mattdm's great answer - but unless I missed it, there is no explanation to the file size - I would speculate that when shooting aRGB and then transforming to sRGB with an intent that saturates the overflowed color (relative colorimetric), then since in the range of the aRGB gamut that is not transformed (not clipped) there are less discrete color ...

sRGB is best for images view on screen, Adobe RGB is best for printing. These are color spaces, which affect the rendering of an image on the mediums. I found that sRGB will give you the most consistent result for screens. NB! No screens will ever give you the exact same result (even if they have been calibrated) color management can be quite complex to ...

Color spaces solve two problems related to color information: imaging sensors can capture a lot more data than can be displayed by any media or device - the data is therefore useless when transferring and storing images; color space defines the range of data that is preserved color space standardizes what each color should look like, so the ...

[afaik] Unless the display driver or application being used applies a color profile or similar to compensate for the wider gamut, the color codes you use in your application will be sent to the display as-is. And in the display a specific color value (say E5) is no longer interpreted in the srgb scale but in the wider gamut scale. So why does the display ...

The real key is going to be that you'll want true 8 bit color resolution rather than the 6 bits that most TN panels get. Off angle color changes is also a key issue when looking at choosing a good screen for any color sensitive work. Having a wider color gamut is helpful, but if I had to choose between a more limited color gamut on a S-IPS panel with good ...

There is no global color space. A color as you specify is just a triplet of Red, Green and Blue. Each component has a value between 0 and 255 (0 and FF in hex) which indicates how much power to give each LED for a given pixel (or phosphor in the days of CRTs). The scale is relative to your monitor and its current settings. This is why monitors need to be ...

If you are not using calibrated screens, then you will get this kind of issue. The Mac screen may be particularly bright and if it isn't calibrated to be comparable to the other screens, then you will end up mixing the image darker than in needs to be to look correct on the other displays. Building an ICC profile for all the displays will allow for the ...

It is very likely that your monitor cannot support the full AdobeRGB gamut. The best way to convert an image from one color space to another with minimum changes in color reproduction is by following the below process: Having set your workflow's color management to AdobeRGB (Photoshop, Lightroom, etc) Having your monitor profile set in AdobeRGB as well ...

sRGB was created by Microsoft many years ago to address the limitations of displays. The variations among displays, color depth, and gamut were far greater then than they are with todays display devices. The "s" in sRGB reputedly stands for "standard", which implies that displays that render sRGB relatively well are in conformance with the standard. Many ...
