Flowers changing colors

[mjbpics]

I took some pictures of purple flowers. However, they turn out blue in the pictures. I changed white balance, aperture, and ISO but they all look blue. Any tips out there?

Thanks.

Are they blue in the camera or on screen? You might need to adjust your monitor, if the white balance didnt fix it that is the only other guess I have.

Purple is very hard for cameras to accurately capture and for monitors to accurately portray. It's a colour space issue. Purples are just hard to do.

Thanks for your thoughts. They come out blue on the LCD and the computer. I guess they are just a difficult shade of purple.

Here's a visualization of it:

The triangle inside the space represents the SRGB colour space that cameras and monitors capture and display. The weirdish triangle shape is the full gamut of colours. As you can see, the purple one is very small and skews to red or blue very quickly.

You'll have to profile your monitor, and your camera (under the lighting of the shot) to really try and solve the display problem of some of the more difficult gamut areas. Even then it's not a guarantee.

edit - you'll have to make sure that you can get that hue or a simmilar to fit within your monitor's gamut as well.
