I'm a dummy. I think I get it. This is not JUST the acrylic light diffuser, it is the acrylic light defuser and the respirator filter. The diffuser is just there as a handy mount.

Dave , here is the component list for the Hickspodisc.

I had to use two of my cheap crystal filters , one was a uv ( for the clear glass) the other was a polarizer for the ring,( i needed the depth) I put the uv glass in first then the respirator filter then the diffuser on the outside, then the little ring that held the glass in , the diffuser had no effect what so ever, it just protected and sealed the cloth type material of the filter. the filter is all that is really needed. nothing else.

I found another alternative, although an obscure one. Our Lindhaus vacuum cleaner has these little white rectanguar HEPA filter pads. I tried using one of those for white balance, and saw the same kind of difference between AWB (too yellow), coffee filters (too blue), and the filter pad as Tom was seeing with the 3M respirator filter.

I just researched this a little bit and discovered that, surprise, these filters are made by 3M. Probably the same stuff.

Tom,

Just when you thought you had answered every question on this topic . . . . .

Any tips on how to get the ring off that holds the glass in? I've been messing around with an old filter so I can give your L Series Hickspo Disc a try, but I can't seem to get that little ring to budge.

Thanks again for sharing such a great idea. You definitely get an "A+" for creativity and innovation! Hope you've already filed for a patent!

I posted my experience with the Hickspodisc in another thread but I would like to state that his thing works. Not only did it improve my postprocessing time it improve my knowledge of how WB works on the 1D.

With the T series Hickspodisc I was able to set up a custom white balance within a few seconds giving me dead on WB. It was so simple and effective that it is easy to use on all of your shots for that perfect WB.

Tom should receive the FM award for innovation and implementation of a very inexpensive and effective Custom WB tool.

Do you have any idea how much money he has saved everyone, who was considering buying the Expodisc.

Thanks Tom!

All this is good for us! I do own an Expodisc, but man would I have jumped all over the Hickspo Disc. Now all I need to do is keep reading for the new Hickspo Disc for all my big glass...300 2.8 and 400 2.8. Anyone tried it yet for these lenses?

I feel badly for the next person that tries to list an Expo Disc in the Buy/Sell forum. I can see the dozens of flames already..."$100?? Don't you know you can get a Hickspo for under $10"

Hi Tom

Test results from the UK.
Tested. Coffee Filters 1/2/3. Pingles Lids,1/2. Respirator Filters1, and from the snack bar whilst getting the Respirator filters a cup of coffee in a polystyrene cup. And the winner was the Polystyrene cup less the coffee.
Thanks for a great thread.

Mike.

Do you guys get your 'lens' filters in plastic cases? I just tried the foam material that comes with the lens filter/case, in the case (as a holder/proctector ) and it works great. You could put any material you like into the filter case, multi layered - coffee filter, printer paper, respirator filters etc, etc.

All of this information is great and the coffee filters work wonders compared to the AWB on my DR. Now I want to build the new and improved version of the Hickspo (??) Disk. The problem is that the respirator pre-filters appear to be a discontinued item. Neither Home Depot or Lowe's has them and Ace told me that they have been discontinued.

3M appears to be making new filters that are sort of rectangular in shape but tapered at one end. I am not sure if these can be cut down or if the optical properties are the same color wise (I can't believe I am saying that about a respirator filter). If anyone knows if these will work or knows of a source for the older ones, please let me/us know.

Tom,

This is the longest thread I've ever seen on this site. Can you write up an article on all this?

Respirator filters? Geez, you're already 2 generations out of date. The current fad is micro-filtration vacuum cleaner bags...

Because the colour adjustment is the opposite of the "filter". When I tested Piringles lids they were slightly yellow and introduced a blue cast - not sure what the coffee complement would be.

I dont want to throw a whole new wrench into the works, but I decided to do some searching on scientific glass figuring I would find something more suitable than a coffee filter (Though I do like the results of my bastardized Polarizing filter turned white balance tool - though a little blue with two layers for me).

This is what I found: http://www.edmundoptics.com/IOD/DisplayProduct.cfm?productid=1671

This seems to me to be the perfect piece of glass as far as I can tell. No color. Diffussing properties. Cheap 100mmx125mm piece is $16.90 plus shipping (they gouge on shipping).

What do you think.

I just might order a piece tonight.

The coffe filter produces a WB that is too blue. The two filter pads that use the 3M Filtrete material do not.
