Default Seeing Red Amaryllis

The Bayer Array which many of our camera sensors use have 50% green, 25% blue and 25% red pixels, which is modeled after the human eye. It may be both the mechanical equipment and our own eyes that have problems with red.

I have two monitors, one which gives a close rendition to one of my two printers. The other printer bronzes a horrible green/brown cast to the shadow areas. I think problems with red are more than just with input devices, output devices have problems too.

Took this last week, used a flashlight to paint the light in a completely dark room. It took several tries before I came up with something acceptable.

Gorgeous shot! And I agree with you 100% about the output device. Your flowers look beautiful velvety red on my large monitor but completely washed out (almost brown) on my laptop!!!

I've got a tablet viewing this and I must aagree the red does look a bit brownish.
Generally the reds from this flower are really brilliant red.

No printer can exactly duplicate what you see on the screen. The screen uses red, green, and blue to build the image. The printer uses cyan, magenta, yellow, and black to create the image.

This image is understandably dark but also rather soft. If you used auto-focus, the low light may have affected it.
