It's a bit late but my semi calibrated CRT, (Hitachi SuperScan Elite 761*), shows them as blue. I thought it might be the screen being off so I tried it on my laptop as well, and the blue elements are blue there as well. On 6/14/2011 11:03 AM, Igor Roshchin wrote: Hi All! After taking

Thank you, guys for all the responses. I understand how fluorescence can be responsible for the color change. (I mentioned that possibility in my original e-mail.) My question was rather, - how can you deal with that... (if at all). Bill, thank you for your story about the wedding problems. So,

Two other considerations - the color of the ceiling you're bouncing the flash off of and the color temperature of the ambient light. A white ceiling may not be the same color as other white ceilings and it may not even be a white ceiling. The bounced flash is going to pick up some color.
