The image output by digital camera is sRGB mode, and the color gamut of sRGB is within the natural color range, so this mode is very close to CMYK mode. After sRGB is converted to CMYK mode, the brightness will be reduced and the contrast will not change.

Canon's film is gray, which is related to Canon lens. The coating of some Canon lenses will affect some yellow wavelengths, and most portrait lenses will affect yellow and blue. The mosaic problem of yellow and blue in the picture is related to this.

There is also a key problem, that is, although the pixel of 60D is large, it is not fine enough. 180,000 pixels is obtained by interpolating 6 million pixels on the basis of CMOS native pixel120,000, which is equivalent to enlarging a picture of120,000 pixels /300dpi to180,000 pixels. The reason is that 1 meter can only become 1 popcorn after heating, not two meters.

If you use high-end printing drawings, it is best to use Nikon equipment. Nikon generally produces 300dpi and Canon 72dpi. Nikon is very strict in the details of film quality. The details of the image are obvious, sharp and saturated in color, and it doesn't need much later stage. The output of 300dp is more suitable for printing requirements.
