There's some very good advice here. My I add something? Sometimes it's the monitor. What monitor are you using? Few monitors are color accurate. You may want to visit a print shop and ask what monitors they are using if you are not able to sort this out with the basic calibration procedures.

White balancing means making the neutral color of the scene (like a grey card) have a particular color temperature and tint in the output picture — to simulate color adaptation of human vision to the conditions of lighting in the scene. If we take a hyperspectral photo of a grey card in a room lit by incandescent light bulbs, spectral radiance of the ...

The ISO of color negative film is derived by the formula you posted. Further, the published ISO is derived by trial and error tests based primarily on the green emulsion which is the slowest layer. Internegative (intermediate)film has radically different curve shapes than pictorial film. The intent is: Avoid the use of cyan filtration in the set-up and self-...

What you have shown appears to be an example of a simple overlay. A semi-transparent mask is combined with a photo. There are many online "apps" that offer such functionality. One uploads a photo, the site adds the overlay which is displayed on the sender's screen and can then be saved to use as the sender wishes. More advanced apps interact directly with ...

To rephrase my question in a more specific way; looking at the three dots on Lindbloom's animated 2D-->3D gamut, the upper dot is out of gamut while the lower dot is in gamut (despite the fact that all three dots appear to be in gamut on the 2D view. How would I know which lightness (Y) values would be in gamut for any specified (x,y) chromaticity? In ...

Also noted is the fact that the Y tristimulus value, corresponding to the CIE 1931 photopic observer, represents lightness due to the choices of the XYZ tristimulus values. Y in the CIE 1931 2 Degree Standard Observer is the CIE 1924 Photopic Standard Observer: there is no such a thing as the CIE 1931 photopic observer. Note that the CIE 1924 Photopic ...

I have noticed a similar effect. I have both RX100 IV and V models and the difference in the colours between cameras is quite striking, particularly unwanted magenta tones in the model V. I've tried to counter that by resetting the White Balance. I bumped up the temperature to 6000K via Menu > Camera > 5 > White Balance > C.Temp/Filter. In the same menu ...

If you look at any color wheel, you have two axes on the wheel: To correct any color cast, this is usually enough. You can correct the main source of color shift in natural light on the temp axis (blue/yellow), and then do the fine tuning on the tint axis (magenta/green). Tint most often occurs through artificial light. magenta red | ...
