Infrared with a Digital camera ?

This fascinates me- I bought a second hand Nikon D70 a while back and discovered that it is used a lot for infrared photography. So Ive ordered a Hoya IR filter and am doing some reading up. Does anyone here do IR with their digital cameras ?

Re: Infrared with a Digital camera ?

I do not do this but I know some people who do. From what I understand there is an IR filter already built into digital cameras in front of the image sensor. To get the camera to take IR photos this has to be removed. I was told that the cost for this can be quite expensive. The images we were shown straight from a converted camera had a strange bluish cast and so had to be processed to convert them the the B&W you normally see although you could also play with the channels to get false colour effects.

I was also told recently that the bare sensors can detect IR up to about 1150 nm which is a long way into the IR range. If that is so there should be the possibility of changing the IR filter in the camera to take images with a different part of the IR spectrum.

Boofers and Simpbow do a lot of IR so ought to be able to give you advice.

Dave bought a camera that was converted to IR and got good results with it - there might be some images in his gallery.

Re: Infrared with a Digital camera ?

Simpbow would be the one with your kind of set up. I use a converted camera with thousands of pictures under it's belt. For me it was a good investment. I still have the same truck I bought 37 years ago so I will have some cameras to convert to different light later if I so choose..life is good when you have taken good care of the cameras you have. You don't always have to sell them. Good luck and read alot of information and ask questions.

The D70 is better than more modern Dslr's for infrared BUT be prepared for some very long exposure times so a sturdy tripod will be needed most of the time

Re: Infrared with a Digital camera ?

No expert in this but try me best, filter am using at the minute is HITECH 85 only cost £10 new,as i just wanted to try it out to see how i went, like yourself i use D70 with 18-70 kit lens on that has done very well so far with the filter attached, use a custom W/B [on bright green foliage] most of the time use F8,11 OR 16 depending on what it is, even at F8 or 11 expect long exposures then all conversions done in PS, you'll have to spend some time in trying to get a setting that you you like, that's about all i can say, you'll find a few images in my gallery to give you an example

Re: Infrared with a Digital camera ?

Remove the dustfilter on my Sigma SD10 and it becomes IR sensitive, so I tend to go for IR + visible results as I can see through the viewfinder and I like the duotoned results. Stick an R72 on the front and that blocks visible (so no view through viewfinder), becoming just IR (but exposure/meter works as per normal - no long shutter speeds necessary - one of the advantages of the Sigma SD10)

Pure IR


IR + Visible
