Very disappointing for you. Not like LCE in my experience I have to say.

Is it possible it's a full spectrum conversion?

Theses are the test images I took....

Don't look IR to me... Surely full specturm would not look like this?

Did you try a hot object in a darkened room?

This is an image taken on my IR converted 720nm K20D of the same flower in my garden and converted in PS, no editing....

No.....

Is full spectrum like proper IR then? Shoot only on sunny days?

Hope I haven't done owt stoopid....

Also.... on the invoice it stated "Pentax K10D IR Conv?" When I called then they said they didn't test it and they also said the widow of the chap who owned it brought in it and she claimed it was IR.

I've never tried IR, UV or full spectrum photography (or X-ray or gamma ray :twisted. But as far as I understand these things, full spectrum means that the sensor gets IR and UV as well as visible light. What the image looks like must therefore depend on the balance between the three. If IR and UV are much less intense than visible, the image ought to look more 'normal' than an IR or UV image. There's also sensor sensitivity to take into account, if it's more sensitive to a particular range of wavelengths then the image will be biassed towards that range. The only way to be sure is to systematically eliminate certain wavelengths and see what happens. A suitable cutoff filter on the lens would do. Alternatively, eliminate sources of all but one of the types of radiation - hence a hot object in an optically dark room.

But as I say, I've never tried it myself .

That's what i read a short while ago...

To be honest... i dont want to buy more filters. I have a case full of them. I much prefer the fact that I can just grab my K20D and go... if i wanna shoot in IR. Think I prefer it that way...
