WB, go ahead and laugh

I'm anxious to try this, as auto white balance seems to be an issue with my K100D, and it is hard for me to get right indoors. Sounds great.

But my coffee filters are unbleached! And I've got a two-months' supply left!

Well, heck with it, I'm off to the grocery tomorrow to get a package of bleached ones. Bet it works fine and thank you for the tip, if you're ever in my neighborhood I'll buy you a cup of coffee!

I appreciate this forum.

You can buy lens cloths which are made to be 18% neutral gray reference color...

By the way, the fact that the auto white balance won't work in tungsten is documented in the manual. The range of auto white balance is specified to go from about 4000 K to 8000 K, and their tungsten setting is like 2600 K.

I'm okay with that, I wouldn't mind warm yellow pictures under tungsten if you don't adjust it... it can look nice and it can be tweaked later... what bugs me is that under compact fluorescents the pictures seem to come out a bilious green.
 
Fluorescents from different makers are so variable that no camera is ever going to match whatever you happen to be standing under, except by freak luck. You need more than one preset just to get in the ballpark of all the weird stuff that's out there.

Pentax could have given us 2 tungsten settings though, much more
useful than 3 fluorescents.

You want mor tungsten ? Average tungsten is how much 4000, 4100 Kelvin ? Use the three presets with a variation of 100K around 4100. You may even tweak it further. Now you have four tungsten settings in WB.

lock ( I use it for low light; 2500, 2700, 2900K)
 
...usually supplying you with sugar, would lend you a bleached one for sure ?
I tell you, it works. I mean, the girlfriend next door....

keeps camera from hunting for focus becasue the filter is covering the lens, i.e., too close to focus

Not all tungsten are the same either.

A Sylvania tungsten bulb is going to be very nearly the same as a GE bulb. One halogen is pretty close to another. And if they differ, they differ in temperature only. With fluorescents, even two tubes from the same manufacturer in a different year may have a significant difference of color, and the difference can't even be expressed properly in terms of temperature, it's outside the black-body color curve.

Not to mention the big gaps in the spectrum that they produce, which can cause everyday objects to seem oddly miscolored even once you have the balance right.
 
Mine are a generic brand. I hope I haven't over sold the idea. I just think its a neat trick that worked in my case. As artist we need many tricks to practice our craft...coffee filter?...check
 
I agreed. And it's simple enuff to customize the tungsten and fluorescent WB.

people just have trouble understanding AWB is NOT meant for indoors.
And Tungsten preset it set for "studio tungsten" which is bluer
though closer than AWB will ever be.
and custom WB is not that difficult

Average household tungsten would be under 3000K

The K100D hasn't got adjustable presets. You get what you get plus one manual WB.

Just half press on something far off, then put the filter in front of the lens. Since your only setting a white point, the image doesn't need to be in focus.

Judging a photographer on the basis of equipment is like speculating one's physique from a gym pass.

 
True. My mistake in adding 1000K to it. But the big point is: I missed the fact that he meant the k100d ! I think I replied to this hread a bit too late in the evening.
