do you mean profession? or experience in taking ir shots, digital or film?

AnCatDubh

Digital IR photography.

I know i need to use a custom WB from a paper or a green grass, do i have to use the filter when shooting the grass? should i use the same exposure as i will use in the original shot?

You'll need to put the filter on when you are taking the photograph of the grass. Once this is done, use that photo to set your custom white balance. Once the custom white balance has been set, you can continue taking photogrpahs normally, with the filter on, at whatever exposure you need.
You might need to take the filter off in order to recompose and focus but as long as the custom white balance remains set then you should be ok.

Your white balance also affects the length of exposure you require for a given brightness. Someone more technical than I may be able to explain just why.

Yeah i realize my mistake that i set the custom WB but somehow stayed set as white balance so the photos are crap, now i have to wait for a another sunny day (6 months maybe) so i will see and if the problem remains i let u guys know, tks a lot.

Or shoot in raw and correct it all later.

Personally I'm quite lazy... so do not do what I do: - buy a cheap IR filter, keep it on auto-white balance, shoot in jpeg...and sometimes if I'm super lazy - use Picasa to convert to b&w instead of photoshop.

On the other hand I'm happy with the results I get (mostly) - since I don't print them out and the laptop screen is only 1 megapixels large.

Just out of interest where can you get these filters?

AFAIK, they have SFX in Gunn's - But I could be completely wrong.

ebay - I got a "Kood" r72 filter - around 15 euro if I recall.

Of course like all filters you can get prices ranging from 15 euro to 50+ euro... it all depends on your needs.

The kood filter should be even cheaper now since I bought it on the UK ebay. I dealt with "surrey photography" - certainly can vouch for their effectiveness.

I bought mine from Surrey Phorography on eBay. I got the Hoya R72. I was out shooting with it today as the sun was perfect was IR shots.
