Why am I getting blue spots when using flash
Dec 5, 2013 17:14:45 #
Last night I took some pictures of our new snow. I took some pictures with flash and some without. The pictures with flash contained some blue spots on the bushes. Anyone know why?

I have been experiencing a lot of trouble posting this. It may appear several times. If it so, I apoligize.
This was taken using a Canon G 12.

Yes, judging from the two pictures, they are shadows from the flash...why they came out blue, I don't know.

Looks like the color temp of the ambient and the flash are different.
Thanks rpavich. What does that mean? I have taken pics with a flash before but have never seen blue shadows. Are you saying the outside temp causes this?

No. :)
All light has a "temperature" think "blue -to-orange" sort of...and everything is a shade of the range.
Flashes tend to be a bit cool...and for the most part, lighting tends to be a bit warmer...so when you use flash, your flash "color" or "temperature" is going to be more blue appearing than, say, a table lamp or a light.
Some folks (me included) put a little piece of plastic over the flash that's a bit "orange" colored to "warm" the flash color to more closely match normal lighting so that the flash part of the exposure "blends in" with the ambient light part of it.
Make sense?

Yes, it makes sense. Thank you very much for the explanation.
Is this true when using film. I am relatively new to digital and have never experienced the blue shadows when using film. From you explanation, it seems film would be affected the same way.

Thanks for the tip on filtering the flash.[

You're welcome!
You can get the gels at Amazon, B&H, or Adorama, they are about $8.00 us for a book of a few hundred different colors...very handy.
Just ask for a Roscolux gel swatch book.

I bought a Skin Glow Bounce Card from Hanson Fong that attaches to the back of my flash attachment with Velcro. It's reversible -- "white" bounce for indoors and "warm" bounce for outside, which makes sense considering what rpavich said.
Now, if we could just have some snow here in Austin, I'd let you know if it'll eliminate the blue-snow effect!
