Finally, after two hours I found someone who shows what non-converted 40D IR photos look like and how much time it takes to make them. And the results are wonderful

I thank you and will keep your blog at close hand

Hey Ronald.. Looks like you successfully made it through part 1 of the process… to get round the the ‘red’ problem, you need to read part 2!

Thank you so much for this,

Im new to IR photography. I have the hoya filter few days ago and try the take some IR photography today.

I did follow all the instruction here. Im using Canon EOS 40d, Hoya IR filter, 30 secs f/5.6 ISO 100. Experimenting a few different exposure.

The results looks awesome on my Camera. However when I transferred that to my PC and open it with Photoshop and Lightroom 2, the color suddenly change to Red, all red. I tried to do some adjustments, etc but still wont give a good results.

Im not sure what I did wrong there. If someone could give me a hint that would be grateful.

Thank you in advance,

Cheers

Thanks. I’ll check out the link.

I have not ever had crazy long exposures and have successfully handheld all my exposures…but I’ll do some more research and leave you an update if I can determine anything.

Thanks again.

Hi Jenn, Thanks for stopping by.

Since I don’t have an unmodded camera, my only answer is ‘I have no idea!’.

From what I understand with the sensor filter removed the camera becomes more sensitive to IR so you can do the same kind of shots but without the ridiculously long exposures. You can even handhold at sensible apertures.

But I have also seen the crazy coloured pics taken with modified cameras. The most popular place for info about modified camera is over at http://www.lifepixel.com/ . These guys do the modification and have tutorials and examples you might find helpful.

So you’re still getting some ‘colore’d light then aren’t you?…shooting with an un-modified camera and only a filter on the lens…

I have a Sigma and so can remove the sensor protector and shoot essentially with a modified camera and a lens (R72 filter.) I’ve tried applying your tips for false color and yes did a custom white balance setting on a full frame of unfocused, sunlit grass.

My images did not come out anything like yours.

Should I try leaving my camera ‘un-modified’ and just use the lens filter? If I modify and use a lens filter should I be planning on monochrome images?

Thanks,
Jenn

Heh heh, I’d love to but I always delete em if I happen to forget… I’ll try and get one next time I’m out. Essentially you end up with all sorts of stage colour defects and hotspot areas – its not nice!

You wouldn’t mind posting some pictures of the differences with the eyepiece cover on and off, would you? Or, you can send me some pics. That’d be AWESOME as well.
