Advice needed on Infrared photography
Discussion
I've had a Cokin infrared filter for just over a year and have hardly used it. However I decided to use it in the lake district recently and got this....
I was bracketing all over the place and checking the histogram for exposure and after tweaking in Rawshooter I am reasonably happy with the above.
I know that polarisers work best at certain angles to the sun, that low angles of light at start or end of day is better/less hazy etc etc etc, but rather than just getting lucky as I did with the above shot I need to understand the theory of infrared techniques a bit better. So...
1. what are the best conditions / times of day etc for infrared?
2. I understand that you should manually select slightly out of focus, but should you focus infront or behind of subject?
3. If using a wideangle with greater depth of field is the focussing less of an issue and it's ok to focus on the subject?
I'm away again in a couple of weeks so hopefully someone can help me before then!!
Cheers, Longers

Guess you have found: http://www.naturfotograf.com/index2.html by now?

Sunny, but cloudy will work too I believeLongers said:

In the good old days the lenses used to have marks alongside the depth of field marks. IIRC used to be about the f5.6 nearer focus pointLongers said:

Wide angle and stopped down a bit will do the trick Thank for the comments

I have now you should find this very useful:

if you wish to go a tad further, i could possibly loan you either an olympus C2020-Z or a minolta dimage 7 c/w necessary filters.
i hope you find what you're looking for .... IR is very rewarding and sometimes most surprising.

Great link - thanks for that!http://dpfwiw.com/ir.htm

dAlso, thanks for the loan of the kit but I think I'll be ok with what I've got once I've read up on the techniques to use!

not sure how much effect a CP will have on IR light worth a try to see the difference.
This surprised me too ....dfwiw site said:
Supplemental Filters
Atmospheric scatter is seldom a concern in IR work, but unwanted IR reflections may still warrant a polarizer. I also can think of a few snowy IR scenes where an upside-down Graduated ND might have helped, but the naturally dark skies in IR photos generally make life easier on the excess contrast front. At altitude, your IR shots might benefit from a UV-cutting haze filter.

Maybe try a less extreme "infra-red"? I have yet to try out the D2X (and not really expecting much), but the D70 gave quite acceptable images with a "deep red" filter, not necessarily a true IR one (I suspect - since you can actually see through it even if it is a deep red) from SRB Griturn that is labeled the R72...
