I've been shooting a lot laetly using Singh Ray ND trio filters on my shots. I love being able to shoot with high power strobes in full sun, cut the ambient down to allow me to shoot at f/2 even at high noon at 1/250th sec. http://unnjscxjerx.com [url=http://nyugakuj.com]nyugakuj[/url] [link=http://vakedylydht.com]vakedylydht[/link] You can always tell an expert! Thanks for contirbuting.
