For anyone wanting to try infrared on a budget, I recommend to get an old (20 years) Sony DSC 707. You can find them for almost nothing second hand. They have a nightshot mode that allows you to take infrared images without modification to the camera.

Apparently also the 717 and 828 have this capability, but my experience is limited to the 707. The 707 can use 1/60 s as shutter speed in nightshot whereas the 828 is limited to 1/30 s.

All you need further is a ND8 filter to be able to take infrared during daytime, and a RG780 (or r72) infrared filter to block visible light.

Put a small piece of tape on the build-in IR emitters, put on the two filters, switch the camera to nightshot mode and off you go.

The picture will have a green tint but can easily converted to B&W.

I'm intrigued -- can you show us the original color and infrared?

I will do this in about two weeks from now. I don't have access to my archive at the moment.

Cool! Thank you for sharing!

I tried infrared using my Olympus C-2100UZ with mixed success at about the same time as you shot those.

I still have both the camera and the infrared filter (if I can find the filter) but the camera can't connect to modern computers and I can't find a card reader that takes SmartMedia memory cards.

Great atmosphere in your shot. I like infrared ... well, often anyway.

I still have my old x-drive which is a card reader for 5 different types with an internal harddisk. It also connects to a PC. It does smartmedia as well, so could be a solution for you (ebay?)

I appreciate the advice, but our postal service is so unreliable that I'm not prepared to buy from foreign sites right now. Well not unless they have a courier service anyway. I had a parcel shipped to me in early March, arriving in South Africa on March 13. After many complaints I received it in late May. By that time the seller had shipped me a replacement which has now been lost somewhere in South Africa since 10 May. I hope it stays lost for another few weeks because the Covid situation is really bad right now and I don't want to go to the post office.

My favourite camera shop was recently selling a used Canon DSLR (650D?) adapted to shoot infrared. If it had been mirrorless I'd have been tempted.

Hi Wendy, here are the two originals. One is a normal color image and the other is an infrared image converted to black and white.
Images were shot using a tripod with short time in between, trying to get a pixel perfect match except for the moving parts (clouds!!).
I think I also did not re-focus in between, but it is a long time ago.

' ' . substr('//images.dpchallenge.com/images_portfolio/0-4999/4008/120/Copyrighted_Image_Reuse_Prohibited_1262849.jpg', strrpos('//images.dpchallenge.com/images_portfolio/0-4999/4008/120/Copyrighted_Image_Reuse_Prohibited_1262849.jpg', '/') + 1) . '

The IR image was layered on top of the color image in photoshop and the blending mode was changed to luminosity.
As a result you get the colors (and light) from the color image with the light effect from the IR image added on top.
It worked especially well in this image in my view, which is not always the case. To be used selectively.

Thanks -- do you remember how you did this step?

The IR image standard has a green tint. I just applied levels correction and a simple B&W conversion. No further tuning.

Thanks! I appreciate it!
