Hi;

I have invested in a new Camcorder and I want to buy some filters, particularly a "Skylight" or UV filter to protect the lens and also some other filters to have a play with some efects.

Can someone recommend where I can buy or order filters?

Thanks in advance.

FotoFile should be able to help you.

Thanks for the tip - will go and get what I need.

As a follow up, do you have any idea where I can buy a Hoya RM90 or a RM72.

I want to do an analysis of some plants and use the Woods effect of the luminesance of the plants to predict what parts of the field are performing better than the other.

Why not call them up?

Thanks - I found out they are illegal in Thailand unless you are the Military. I don't like it, but they are the rules.

um...illegal...

i guess ebay will be a good source for Hoya filers

what size will you need?

I can get them from Singapore quite cheaply - in fact they are nearly 30% less than the USA. I suppose its something to do with Import Duty as the USA still make photographic Filters, and Singapore probably does not..

Ok, so I got my IR filters and they are not illegal, just very difficult to get someone to order.

For those who are interested, here is the sample of the Glow or Woods effect under longer wavelength light. This is using the rather expensive Hoya RM90. This is the full color

and here is the same Basil plant with the RM90 applied

Pay the extra and get decent multi-coated filters and remember that a PL filter needs to be rotated to the correct position to work

I get my filters at a shop in MBK as they have been the least expensive I have found. They are on the ground floor on the Phayathai Rd side of the building. The filters are just inside the door at the counter on the left.

(It is an excellent camera store and if I remember the name I will post it!)

Interesting to know that IR photography works in the digital world.

Astral; it sure does, and its a cost effective way of doing the projects. The pictures above were my first effort, however, the cost of film and the difficult techniques of handling and processing the film has really meant that IR was out of my reach. Now the digital world particularly as the CCD sensor is sensitive to long wavelength light makes it a viable proposition.

The fastest way to test is with your Camera or Camcorder. Point any IR remote at the lens of the camera and look at the result. If you can see the Remote flash brightly, then you know you are ready to put on a filter and start exploring. If you see a very dark red spot then you may well have a IR blocking filter, which can be removed by the service team. Or if you have a "Night-Shot" mode, turn that on and you can see the result.

As my project is to try to pre-forecast a Rice Crop yield with the variance of the Woods effect, I don't want to burn out my HD camera with too much IR radiation, so I am also using up to 12 stops of ND filters to keep proper control of the exposure.

Good lick, and hopefully soon I can publish some shots that look like it has snowed on a rice-field.
