Dear panoramist,

I remember to all of you that I am a retail optician in Brussels, Belgium.

About graduate filters, you have to know that it's very easy to made some
yourself.

In any rx spectacles glass factory, who made glass (mineral and organic -
plastic )  for retail opticians, they made any coloration on organic
eyeglass, they put the plastic glass in some tinting liquid at 90-95
centigrade temperature for a few minutes.

 The tinting powder come in different hues as well neutral gray and is very
inexpensive, you can color a lot of glass in one liter of liquid.

 The coloration is darker as the glass stay more in the liquid.

They made easily graduate by immersing more or less some part of the
plastic sheet.

With some training it is maybe possible to made some central dark spot.

I hope to have give all off you some usefull informations.
