IR Conversion.

Hi guys, need a bit of advice here from someone that has had the IR conversion done, have got D90 but have to wait till Santa time & i am now thinking about converting the D70 to IR, is it worth while doing this or is it just simpler to stick with the R72 filter, if doing the conversion what's the best one to go for & also i was thinking about the shutter as its never been done since ive had the camera do they do that to or does that have to be sent to Nikon, cheers simpbow

Re: IR Conversion.

Considering the amount of IR that you do, I think that a conversion will not be wasted.

I'm sure that in another thread Dave posted a link to a company that specialise in IR conversions. IIRC about 200. Not sure, but I think the link went to an e-bay advert.

If the shutter is working OK I think I'd leave it alone.

Re: IR Conversion.

The company who does this in the UK is:

Advanced Camera Services

I had my Canon EOS 20D converted almost 18 months ago. My 20D was in good condition I had owned it since new and less than 15,000 shutter releases. For a D70 it will cost about 250 plus VAT.

What they did with mine (though it was part of the standard conversion) was:

a. Remove existing IR blocking filter
b. Move sensor back 1mm (or change the firmware)
c. Add the new 720nM IR pass filter
d. Give camera a general service

The removal of the blocking filter then means that you can use normal exposures. Moving the sensor back means that if you focus (manually or auto) on visible objects the IR will be correctly focussed so no need to worry about IR markings on the lens. Another colleague who more recently converted was told that they change the firmware rather than move the sensor. Whichever, the effect is correct for IR. The new 720nM IR filter blocks almost all visible light leaving near IR for the sensor to record. DSLR sensors are sensitive to visible and near IR light. With the 720 nM filter you can produce "colour" or B&W IR images but you could choose an 840nM which is OK for B&W but less good for Colour.

Please be aware although B&W IR has been around as long as I can remember, IR colour was quite rare for film and many find colour IR an acquired taste. You can see some examples on my website.

There is no comparison with just using an R72 filter. I gave this up very quickly because you had to use a tripod, cannot see anything in the viewfinder, shutter speeds were about 30 secs and everything moves in that time (clouds, foliage etc.) You can use the converted camera just as normal. If you go ahead, once you have your converted camera there is more useful information I can help you with. Some is on my website but I need to update it with additional things I have learnt in the last year.

Re: IR Conversion.

That sounds like a good deal if it includes a service too

Re: IR Conversion.

My 20D I just had done had about 80,000 fits of action on it, I didn't worry to much because shooting 720IR is in a short range of actuation speed and can be done quite regular in manual mode. Another point not answered is you will miss the long exposures for soft water as I have seen some of yours and extending your exposure time with a convert will burn out your picture with the 720. I haven't tried with my other one yet. I like the colour,,"see how I spelled it" but the 720 is my fav. I was able to convert a new rebel 10 mega pixel to 720, the rebel doesn't have all the bells and whisles but I haven't needed them. It's a great thing we can do to have an old camera converted and the prices or low right now. Go for it when the time comes and I hope you can pick the right filter for your needs.

I'm new to using these forums, so forgive me if I'm putting this in the wrong place....
I have acquired a canon 20d and was thinking about this conversion. I've played a little with the filters, but the tripods etc are all too much to carry so this option sounded good... My question tho, is, can you get some of the stunning effects you see on line, without having to play with photoshop? can it all come good with white balance etc?
Sorry if this sounds silly to you, but I don't really understand all the settings and photoshopping process. All bar one of my pics has come out just red and not sure how i change it.

Re: IR Conversion.

Hi and Welcome

You need to get your WB custom set. So if it is a normal IR72 filter then shoot grass in bright sunlight.

Set that shot as your custom WB. Then when you shoot another shot you should see it more orangey. The right custom balance is important. Also if you have a custom WB you will need to use Canon DPP to covert the RAW a photoshop is bad at this.

Some great tutorial on Lifepixel

Then you get the shot more like you see in some shots. Some post processing may help. To get the blue sky effect you need to channel swap.

Re: IR Conversion.

I just love this place,,. It sounds like you should get the pure B&W filter. I started with a little color and also love photoshop....I should say that I can get some really good black and white out of the camera by turning down the color. I Use an old green color filter under an expodisc and point my camera at the sun. I do this for every IR camera I have and set all to custom white balance, no red with that method. I would like to mention that I bought a new 400D and had the 720NM conversion. Very glad I did this because it is light and easy to use when you have two cameras to handle. To me the 720NM is the best one so a new camera was a wise choise for me. Good luck with your trek..
