skylight filters

I want to get a skylight filter, for 2 reasons: first, to protect my

lenses. Second, to warm up the colors a little.

The recommendations I get are to get a skylight 1-A filter, whose

effect is very subtle, so you can keep it on your lens at all times.

The problem is that each company makes other kinds of skylight

filters. For example:

B+W and Heliopan: KR-1.5

Hoya: 1-B

Tiffen: 1-A

 

The KR-1.5 is said to be like the 1-A, but its color is different.

 

Any suggestions? Is the 1-B really that different than the 1-A?

Does anyone know of a site where I can find some real data (i.e.

numbers - Kelvin temperatures etc.) about these filters?

I'm assuming you use slide film? If you use print film, you might as well have a clear UV filter as a skylight will make no difference to the colour of the prints. With slide film, try an 81 or an 81A first, as these are a more natural brown colour. The 81B is far too strong in overcast conditions and is best saved for open shade on sunny days or the studio.

<p>The KR 1.5 filter from B+W corrects color temperature from

3,400K to 3,200K</p>

mainly with Wratten filters, but you should find it pretty useful.</

Getting back to the original question: The skylight 1-B was intended to absorb a bit more green than the 1-A does. So it's alittle warmer. There's also a Nikon L1Bc, or something like that--I can't seem to lay my hands on mine. It's like Tide vs. new improved Tide.
