Question digital IR

Anyone know much about shooting infra-red on digital? I have just borrowed a filter and wondered if anyone had some advice about what kind of things work well?

Re: digital IR

Plant foliage works well, so grass , trees (although leaves gone from most now)

Steps to start out.

1) Ideally set WB with filter on. Due to darkness of filter you need to set ISO1600 & then set custom WB by pointing at grass.
2) Return to low ISO & set to shoot RAW if possible
3) Due to long exposure needed you'll need a tripod
4) Turn to manual focus
5) Take filter off & compose shot. Put filter back on being careful not to change focus
6) With camera in Manual mode choose something like 20 sec exposure at f/8
7) Either through remote cable or self timer , take shot
8) Once taken , view histogram of shot. If too dark, increase eposure & vice versa
9) Voila , IR shot

Note the IR focus point is different from normal light focus point. Older lenses used to show this position, but I always put to infinity position & play it by ear.

Have I missed anything fellas & lasses ?

Re: digital IR

Sounds good Dave, except I haven't used a tripod yet I would find some kind of other subject to have in the picture besides foilage, houses signs and old woodin things. Don't know where you are, but pampas grass makes a great shot, and most grasses are going to seed this time of year,,have fun Jaime.
