I posted this message in "Talk about Photography" and only today realized it was better placed in this forum, which I seldom visit... so here it is...
_______________

Some of you may know that I'm shooting infrared with a modified Canon G1 which has had its hot mirror (internal infrared cut filter) replaced by clear glass, producing a camera capable of normal shutter speeds with either a Hoya R72 or B+W 093 infrared filter.

Since I began posting photos from this camera on my website, I've had several people write and ask about modifying their own cameras.

Thanks to the technical knowledge and generosity of Tony Kaplan, the man who did my modifications, plus my own undeniable skill in creating a simple HTML file, the secret to converting your G-series camera is now online at www.kleptography.com/n​otes-irconvert.htm (external link)

Excellent info Don,

I just made this thread "sticky" and would encourage this to be the new home of -G- series infra red shooting info and tips if anyone has any to share...?

Hi Bruce... it's a pleasure... I hope it's helpful (I guess we'll know with a little future feedback). Don

Hi CDS,

That's kind... I hope someone finds it useful. Those who like infrared photography tend to be a little fanatical and this tutorial may help them reach another level of ease and performance.

As for tips, I'll start off with my best one:

The secret to escaping the magenta plague (which is interesting for only the first dozen shots and only infrequently thereafter) is to stop shooting in JPG.

1. Shoot RAW on P mode with AUTO white balance.
2. Convert to TIF in BreezeBrowser (for instance) using a CUSTOM white balance -- which is as simple as clicking the eyedropper in BB's preview screeen on anything that is a medium to dark gray (it really matters very little).

Using an unmodified G1 with a Hoya R72, you will often get localized pastel-green hues on foliage that are quite pleasing.

But in any case you will be rid of the pinks and magentas and oranges.

Cheers,

Don

Would it be worth my while to find a used G1 and modify it or just use my D-Rebel for IR photography?

Hi Colin,

What a late reply... sorry, buddy. Next time if you're on the verge of a purchasing decision, just send me a personal message.

I don't know how sensitive the D-Rebel is but I would think that it's not as sensitive as a G1... and even if it comes close, it's never going to be as sensitive as a modified G1, so that's what I would do.

On a technical note, your photos from the modified G1, especially with the B+W 093 true infrared filter, will be virtually black-and-white, so you won't have the opportunity to do any fancy channel swapping to create colorized infrared photos if that's something you long for (I don't).

There may be a tinge of color with the modified G1 and a Hoya R72 but, again, not enough to play with for any sort of dramatic colorized picture.

At first, I was disappointed when I modified my G1 and found no color, but that lasted about 20 minutes as I began to appreciate the benefits of not only handheld but high-speed infrared photography.

When I purchased another G1, I thought I would leave it alone and use it with an R72 to regain those colors. But after a day of tripod shooting, I sent that one off for modification and have never been sorry. In bright sunlight, even with the stronger 093 filter, you can expect shutter speeds up to 1/500th of a second.

So there's one man's opinion. :D

Let me know how you get on.

Don

The Glass Sandwich

One of the people who actually read the IR conversion instructions wrote to offer an alternative idea for the replacement clear-glass filter -- microscope slides.

They're easier to find and cut, so you might want to consider them over a single piece of tiny glass. I've added Hiroyuki Yoneshima's comments at the end of the conversion page, along with a picture of our Hiro on Half Dome.

G6 and Infrared

Oh boy!
am I an excited person now! I've been shooting IR (film) starting a few years back but recently aquired the G6 and have been having lots of fun. I was incredibly disappointed by the colour results, and thought perhaps it was an issue of the G6. As soon as I read your post Don, about shooting it in RAW so I promptly turned around (at work), stuck the R72 on and did a test shot.

It still looks brilliant orange, but I hope that will change when I get it back home. I use Photoshop7 though, and am not sure how to make those changes. I will play around and hope.

I've found that I can squeeze out shots that are fairly good at F2 and as fast as 1/15 seconds - ISO 50. As I have just got the camera a short time ago, and only bought the R72 a few weeks later, I haven't had much time to play with it. One day I hope to convert over an older G3 to IR... when they are cheap-cheap in about 4 yrs. ;)

Don, after joining here I found your website and have found it very inspirational. Thanks for all your hard work.:D

Thank you for all the info Don, but I really do not trust my skills to do this. Is there anyone that will perform the conversion? Been thinking about calling the local repair shop.
I played with a R72 filter with my G3 and the focus seems alright, but when I used the 20D it had a harder time. Do I need to manual focus, and if I do do I need to back off a little for IR?

Hi Zero,

Sorry for the delay... this sticky thread got lost when Pekka moved to new forum software and CDS was obviously kind enough to go find it and stick it again. Unfortunately, my "email" request for new messages was no longer there and I simply tripped over this today.

Photoshop 7 is fine... it's BreezeBrowser that you use the "custom white balance" technique to get rid of the pink, magenta or orange color. When the RAW image comes up in BreezeBrowser (Ctrl-K), just click your cursor on something that's medium or dark gray and take a look at the results. Play around a bit and try different areas to see the effect. When you see what you like, covert the image to 8-bit or 16-bit TIF (8-bit only for G1 users).

If you really want a converted camera, you might consider buying a G1 for the cost factor.

And you're quite welcome... glad you found my website and enjoyed it.

Good luck.

Don

Hi,

I'm sure there are people who will rip your camera apart. :D It's the putting it back together properly and checking it to make sure it focuses properly THROUGHOUT THE ENTIRE ZOOM RANGE. It definitely needs to be tested before it's returned to you and this is the first test you'll want to perform yourself.

Unfortunately, the man who did my conversion and several others no longer wants to do them, so I haven't got someone to recommend.

I'm sorry that I can't help you with the 20D question. I use auto-focus only on the G1, but it sounds like you're having problems with the 20D. Perhaps someone can jump in here and suggest something.

Good luck.

Don

Don, thank you for the information. I haven't played with the 20D and IR long enough, so it's probably user error.
I have a friend who said he can take it apart and put it together, I just need to get the glass :) I do trust his compentancy :)
Thanks for commenting on testing the focus at all ranges, I probably would of gloss over that.

Hey Don, I have a question about taking infrared shots. Is there a certain filter I can get for my G6 that can help create an infrared shot? I am so captivated by these that I want to take some of my own. Or is there a way in Photoshop Elemetns to change a picture to make it look like one?

You can try the Hoya Infrared filter found at www.lensmateonline.comexternal link

It's more for the G1.

You can also try some post processing using Photoshop. Here's an action you can use: http://www.nickgallery​.com/web_pages/technic​al%207.htmexternal link
