p.1 #1 · Yet another alternative to ExpoDisc

This NOT to start an ExpoDisc vs. Prangles war. It just to show that a good, white, BLEACHED coffee filter can be a great and dirt chip alternative.

The photo was taken under mixed fluorescent/incandescent light with a 50mm f/1.4 lens. Actually, I like the way the coffee filter balance rendered the colors, I think it's better than either gray or white card.

Yeah, I can just see the looks you'll get putting a coffee filter over the front of your camera...

Seriously, however, it really looks like it does the job.

Hey, I might have to keep another filter in my bag. Great idea and the result looks good.

THicks, I'm glad you liked it. I guess, the next step is to decide which brand of coffee filters is better - Hoya or Maxwell House. Or Hoya is not in it yet?

I was using IGA, btw.

Works great. You can buy a lot of coffee filters for the price of an expo disc.

Be sure to use decaffeinated, or else you'll need a tripod.

Being new to this WB thing, what is the process you use? Point towards subjet/light source? Set custom WB prior to exposing, or change it in PS or other software? tks.

Ed, it's very simple. Put a cone filter on your lens (or double cone if you feel adventurous) point it toward the subject and snap a picture. Doesn't matter if it's in AWB or CWB. Then go to Menu, Custom White Balance, and set the pic as your reference WB. Don't forget to switch to CWB (if you're not already in it) before taking photos. Hope it helps

Do you think cutting the center out of a 77mm lens cap and fitting the filter paper to it would work as a poor man's expodisk?

Well, that proves the point: Canon AWB = Automatic Waste Basket. It's a sad day when a coffee filter beats the AWB algorithms...

After this, there's no doubt a product niche: 'L' coffee filters...

Harold, actually, I tried it too, it works. Put two layers if in doubt.

How perfect, they're even white!

I think I'll get out my Magic Marker (tm) and put a red ring on mine.
Or maybe a green ring for "DO" (decaf. optics)

Very clever idea and the best part is how small, light and cheap the solution is.

Thanks for sharing this one!
