Digital IR

Am I the only one who photographs with IR at night?







Obviously, there's very little IR light from natural sources available then, but there's often a lot of IR light from artificial sources bouncing around...

Well, I have never considered doing this, but you have shown us that things can get interesting! I will definitely give it a try.

Here is a shot I made with a full spectrum camera using a 680 nm filter. Plants often go completely white with 720 nm or higher conversions, and in this shot the leaves of the plant would have had no vein definition at all.

The camera I used was a Sony a7r 11 converted to full spectrum.

Very nice Sandy! My next conversion has to be full spectrum!

These two images were made with the 720 nm filter, using the same Sony a7r 11 conveted to full spectrum camera.

My approach to use of IR is a bit different from most as I tend to avoid the very high contrast of sunny days and photograph in low contrast situations which gives e the opportunity to selectively increase contrast.

I've been one of the 'full sun' IR shooters. I might have to re-think that! Nice images.

That's a very gentle, smooth effect, Alan. Well done.

Thanks Ari!

And here I am, using a very expensive Heliopan IR Cut filter on my Blackmagic camera to keep infrared from messing with the colour of my footage, not to mention pricey Panavision/Lee Neutral Density filters with IR Cut for the same reason

Horses for courses!

Question for 'full spectrum' folks: Can you live view focus through an R72 filter?

I must admit that being able to choose a different IR filter for different conditions is highly appealing.

Yes, if your camera is mirrorless or has live view.

Attached is a brief article about full spectrum conversions.
