I hope I'm posting in the right area - I'm kinda new to this...
I took this macro of a Storm Lily, and overall I'm happy with it, but the petals should be a bright white, not blue. Any suggestions on how to fix this would be appreciated! I've played a little in Elements but I'm just learning how to use it, so there's probably something obvious I've missed. EXIF available on Flickr.
Any other suggestions - composition, framing or anything else - would be appreciated too.
