Q: 5. Using flash outdoors (flash dialled 1 stop brighter than sun), id like to reduce the blue saturation of the ambient daylight (in a colour image, not B&W) will this filter reduce/mute/gray the blue saturation? If anyone has tried this, can you please direct me to an example image? Thanks everyone!

A: Colored filters are usually meant to be used to change the contrast in black and white photography. If you were to use a yellow filter while shooting color, the whole picture will have a yellow cast. The best way to reduce the blue saturation would be to either overexpose the sky, or ideally in post production you can under-saturate the blues.
