No you don't need to calibrate every shot. Set white balance to kelvin and get it where you like it for the scene. (Never use AWB) If the lighting changes, also change the white balance and reshoot the card. If you never have to change white balance but go from outdoor lighting to indoor lighting, reshoot the card when you go to artificial light. That ...

Below is a note from EXIFTools documentation - "1) Some tags (generally tags which may affect the appearance of the image) are considered "unsafe" to write, and are only copied if specified explicitly (ie. no wildcards). See the tag name documentation for more details about "unsafe" tags." Also, see question 9b on this page: ...

Yes, Facebook does assign a different ICC color profile to the images which is an edited black scaled sRGB IEC61966-2-1 profile. More information and ICC download link for C2 here: https://www.facebook.com/photo.php?fbid=1522920917921431

The lighting situation is far more important than the lens. (Lens colour casts are really very minimal these days.) You can try to use a dual-illuminant profile, but that will not account for the illumination spectrum that's actually present when you're taking a picture; it's just a basis on which to make gross colour temperature adjustments. If you want ...

You would convert the image to the sRGB color profile. This profile is indended to match the color capabilities of a monitor. This is commonly used for images that are used in web pages, and for example offered as an option when exporting images for web in Photoshop. By converting the image to sRGB the color profile can be omitted from the file, which ...

Taking an image "Outside" does not guarantee you D65 color temperature, unless measured. Also without having drivers adjusted to provide a D65 simulation on your monitor, the results can not be accurate enough to be called calibration. Even with the cheap calibration devices available it is difficult to sometimes get an accurate match between monitor and ...

In theory, this seems fine, but a cheap color calibration device gives you steps 1 and 2 already done, plus 3 done with many, many more samples than a color chart, and 4 done automatically. I'm willing to bet that inaccuracies in the first steps plus the limited number of samples add up to less-than-ideal results. With a "real" colorimeter costing under ...

In theory, DisplayPort enables you to get the most out of your monitor. How much you will notice the improvement depends on a lot of factors; proper calibration, ambient lighting, your own colo(u)r perception and so on. Thath being said, the image certainly won't get worse. Maybe your pics will look worse, because minor details suddenly become more ...
