Cool Spooky infra red!

Here is a sneak-preview of my forthcoming DPNow article introducing infra red photography:


Taken with our infra red converted Olympus Pen E-PL1 (processed in LR and PS CS4 to mono). Notice that my sunglasses have become completely transparent - even the dark plastic of the frames.


And here is the normal visible spectrum view taken with an unmodified Pen E-PL2.

Ian

PS I hope to have prices for hiring the IR E-PL1 available by the end of today

Incidentally, there is an infra red post processing challenge currently running on DPNow if you are interested:

So those adverts for X-ray specs on the back of comics were real! Just thirty years before their time ...

Re: Spooky infra red!

Years back before drug testing was done by TLC (thin layer chromotography) the reading of the plates under UV long and short and sometimes Infra red was a mixture of art and science, certain drugs fluor or absorb light diffrently under set wavebands so, as most of it was memory work to help new staff members I managed by removing lens from SLR and we did a sort of pin hole and it actually worked, I have the slides somewhere.

Back when I experimented (not very successfully!) with IR film, and had to keep it in the fridge, I used to tease my sisters that it could see through clothing. It didn't take much to persuade them that it was true

With no blocking filter and the right IR pass filter, it would be possible now, didn't Sony have to modify a whole range of camcorders because the Nightvision could see through clothes as it used just the right band if IR?

Re: Spooky infra red!

By the way, is it really worth having a body converted to IR compared with using an IR filter on the lens ?

Well, my take on that would be that it depends on the type of pics you want to take.

Its difficult to take pics of people or other moving objects with a filter because the shutter needs to be open for so long, also I found I had to focus, set up the shot, then add the filter and take the pic 'in the dark', sometimes it works fine but screwing on the filter sometimes moved the focussing ring and it was difficult to get things sharp.

A converted body gives you the same freedom as visual light photograhy and you use the camera in the same way. This means you can have much shorted shutter speeds and you can see what you are photographing as you take it. I am enjoying IR photography so much more than I did with a filter and I use it much more, I take it with me whenever I go out and often get it out simply to experiment. I certainly dont regret buying a converted body.....! Now how many women have you heard saying that!

I hope all this makes sense, I am at the very beginning of yet another steep learning curve and I am sure there are others with much more expertese and experience than I have, who will be able to give you a much more technical response.

Re: Spooky infra red!

I take your point, thanks, I had not thought about moving objects or people. Personally, I'm only interested in IR for landscape, so I feel that my Hoya 72R is sufficient. Still, I put an IR converted body on the list, just not the priority one.

If you were interested you could always hire Ian's camera and see what you think before buying one yourself.
