ir filters are here...

...arrived today.

it has been raining all week and will continue to rain till sunday (if the weatherman is accurate, bets anyone?).

iirc, the sun should really be out when shooting infrared film?

You'll get the best results when it's sunny out, yes. Technically there is, of course, sunlight when it's overcast, but then the IR effect is very slight.

maybe sunday if i'm lucky...sun that is.

Best time of day, best conditions, from what I have read and experienced : afternoon, when the sun is coming in at a low angle. You notice a red shift naturally, that means your IR film will also notice it. . . less blue light in the scene will increase the effects.

Clouds scatter the rays, block alot of it, etc. Wait till the sun is hitting the scene directly (without stuff getting in between).

Also shoot with your back to the sun - you'll notice a strong difference in your skies depending on where the sun is in the sky.

The IR effect is due entirely to reflected and transmitted near IR wavelengths originating from the sun, so on overcast days the effect may be minimal.

Some of the best IR shots are taken in late morning and early afternoon, whereas early morning and late afternoon are ideal for a lot of regular B/W and color. So if you combine IR with conventional photography, all of the daylight hours can be used to best advantage.

That makes sense, I guess. Perhaps I misread early as late. Late afternoon, you have alot less intensity, although more red end light per unit. Whatever unit that might be.

All my most effective IR was taken 4-6pm here in Seattle. Still light here till 9 or 10pm.

All afternoon seems to be good for IR here in the mid-Atlantic states. The effect, of course, is quite different at noon than it is a 5:00 PM. I just like to reserve the early and late parts of the day for conventional photography.

Also, I'm using a digicam for IR. My experiences would probably be different with film.
