Re: PESO - Blue Snowflake
Interesting way to get a yellow gradient background. Can't explain the blue color, but it looks nice.

Re: PESO - Blue Snowflake
Interesting observation - in a sense the droplets (rime) could be acting like additional lens elements and altering the refraction of light. I am hoping to work with the yellow filter a little more and if this turns up again I'll turn off the mufti white balance to see if that affects it. I have never seen this with red filters in the past. Mark On 1/28/2015 10:52 PM, Igor PDML-StR wrote: Mark, Your guess about the auto-WB compensating for the yellow light is very plausible.

It looks like the blue color is where there are some sort of "droplets" on the snowflake. I wonder if it's the interference on the two surfaces of those "droplets". Nice image, as usual.

PESO - Blue Snowflake
We had e a little snow on Sunday but it was mostly rimey and poorly formed. I took the opportunity to try using a yellow filter, just to experiment. In this shot the background is yellow but the crystal itself is mostly blue - maybe an artifact of having the multi while balance featured enabled. At any rate - it was something different : http://www.markcassino.com/b2evolution/index.php/blue-snowflake Watching the weather reports - I hope to try some more yellow snow shots soon...
