I assume you're speaking about JPEG (.jpg) files. No, the colour information can't be restored. If the image was converted to greyscale it doesn't contain the original RGB data. Some programs just fail/omit updating included thumbnails in JPEG files. You can sometimes also see the full image prior cropping in a thumbnail which can be pretty undesirable in ...


Want something like this ,just figured by chance that you can use (linux only)GPick go to tools -> Palette From Image ... -> pick the image and set number of colors to one this will give you the exact color if you try @clabacchio solution.


There is no detail because the red channel was clipped (too much exposure). White Balance (Daylight and Flash and Cloudy and Shade) shifts the data to the right in the histogram. These shift red right and blue left, which can cause bright red to clip. It's just kinda how things are. You can monitor this result in the camera histogram, specifically looking ...


Red has the lowest of the color temperatures. Back in the days of film, it was possible to use a red light in a darkroom, because the color temperature was so low, the paper didn't pick up on it in the time it took to expose and process the photograph (sometimes up to several minutes). So it's very easy to blow out your reds. Too easy, even with 47 years' ...


In my opinion, leadership, creativity and flexibility are not best conveyed by the backdrop color of a headshot. Note that I said headshot, as that is what I would typically recommend for any resume/CV image. Instead I think that it is important to consider your audience. Are you(or the user of the image) applying for a position as a manager in a ...


This question is tagged "history" so, some history -- Photographs (of course) don't have to be literal captures of a scene. Plenty of photographers (past and present) have manipulated the image to reflect their feelings about the subject (or other stuff). Pre-digital (and really, before desktop computer image editing -- which pre-dates pure digital ...


White balance is applied while processing raw data. The purpose of white balance is to reach R = G = B for neutral (grey, non-colored, achromatic) areas of the image. The whole problem arises from the fact that color channels of the sensors (for typical Bayer, those are R, G1, B, G2) have different "sensitivities", and the responses also depend on the ...


Here are some of the ways: I use a monochromator, light sphere, and a photodiode. You can find most of those supplies at Edmund Optics and similar shops. You ...


Yes, color sensitivity is often measured and specified in bits. DxOMark provides one example and incorporates this into their camera ratings. From the description of their "Color Depth" test: Color sensitivity indicates to what degree of subtlety color nuances can be distinguished from one another, often meaning a hit or a miss on a Pantone ...
