Come and see, everyone! This is a portrait sample of Nikon D7200 … Why is it a little gray? It seems not as good as D3500. What's the problem?

It is normal to put Nikon SLR optimization calibration mode in "standard" mode, and the photos taken directly by JPG are gray and have weak contrast. It was deliberately designed by Nikon algorithm. The advantage of this setting is that there is more room for adjustment in the later period. The easiest way is to set the optimal calibration to "bright" mode, or you can adjust the parameters such as contrast, sharpness and saturation according to your own preferences in the camera optimal calibration settings. In addition, if the commonly used metering method is matrix metering, you can adjust the matrix metering option to -0.3EV in "b5: Fine-tuning and optimizing exposure" in the custom menu, so that the exposure is more accurate and the color is better.
