Colour correction gels, (like filters. The main color correction gels are CTB (color temperature blue) and CTO (color temperature orange). A CTB gel converts tungsten light of 3200K to 'daylight' color. A CTO gel performs the reverse.

Nice ones Gary, well captured, would love to see some.

Fabulous Stained Glass and capture of by you Mr Trout, nice ones!

Most of these emit fairly high levels of both UV and IR, but generally are always shielded. The probability of any UV damage/degredation only really occurs when the lamps/housings are damaged.

As far as skin damage is concerned it is the UVA (longer wavelength) and UVB (medium wavelenght) and a lot more damaging than UVA. This spectrum is between 100 and 400 nanometers.

UVC is the serious one, (Atmosphere screened) - this is where a lot of the Ozone layer, or lack of it, gets some bad press.

Your flash will have a colour temp rating of 5200- 5400k [Kelvin], (cool colours - bluish white - near daylight), where you should get consistent colour results.
Tungsten is around 3200k

Metal Halide lamps are nearly always around 5000-5200k but tend to be a little expensive and generally dont hot start.

You can buy Tomato grow lights which would give you the needed range.

Wrong Mr Riley, he's just careful with his coin......

Of mine: -
Some Pentax, some Third Party.

Some of each have and some havent. Significance - No idea.

Hi and Welcome to the Forum.

Have a look round on sites like these: -

http://www.ebay.co.uk/itm/2X-New-Battery-for-PENTAX-K-5-K5-K-7-K7-645D-645-D-LI9...

N.B. Th ebay one is for 2 batteries!

I have some of these and they are equally as good as genuine.

Good luck

Nothing to 'prepare your bile for'!!

AS JR says nothing more than incomplete reporting, quite typical of todays Media as a whole.
