Its quite easy to do with an IR filter--you will have to compose and focus and then add the filter, but that's not a big thing.

(having major problems with a dialup of AOL--arghhhhhhhhh!!). I wanted to add the D30 test.



If you want to use your camera for anything else BUT IR, it is doable--altho' I would much prefer using my D30 to D60--quite a difference in shutter speeds.

for iR stuff...as much as I love the D60, I can't shoot any iR with it. What takes the D60 like a 30 second exposure is like 1/10 sec. on the DiMage 7.

I enjoy it enough and I think it's th eonly sacrifice I made on the switchover - which I don't regret for a second.

Yep, just my thought ... a D60 is too expensive for most of us to be a dedicated IR cam.

The G1 might be a cheaper alternative. I heard that it is possible to remove the internal CCD filter and use the G1 with an external IR pass filter, so that freehand IR shooting becomes possible. It should also be possible to use an external hotmirror for normal color shooting.

But this also isn't a job for do-it-yourselfers.

Nice comparison ... a big difference.

I'm curious about your next IR works, especially if you come out with an IR color image again :-)

Filter is fused into a frame which is mounted on the imager which
is buried in the camera. Many hard and flex boards need to be
removed which involves soldering. If the imageer is not mounted
correctly the camera will not ficus properly, if the wrong size
filter is mounted or if the filter isn't mounted correctly it will
damage the shutter. If the old filter isn't removed properly the
new filter cannot be properly mounted.

I've taken apart cameras before I successfully modified a G2 to take IR pictures, though its AF performance is rather weak when going through an 89B IR filter.

Help me out. Did you use a gel filter or a glass filter? How did you remove the old green filter?

Pictures are welcome!

Peace, Rolland

Diane,

It is true that after such a modification the camera only shoots in IR. My reasoning is as follows:

I love and hate my D60, The reason I love it is the image quality. THe reason I hate it is that I have bought a 10D...which I unconditionally love!!!

I wouldn't sell my six month old D60 for the $1000.00 it is now worth, nor did I want to shoot it as it cannot perform as well as my beloved 10D. By converting the D60 to IR it now has a new life in my camera bag! Anyone who has a D30 or a D60 which they don't use but can't part with would welcome a new and unique use for the thier old camera. Also, used D30s are easily bought for a song and a dance and with this mod they can shoot IR without any of the previously necessary liabilities involved in digital IR photography.

I need both my cameras to be able to shoot color, so it won't work for me. For those who have the extra camera, then your approach would be reasonable.

Hi,

though the D30 is nice for IR, it's sometimes not sensitive enough. In such cases the G1 still does a good job, especially because you can see a great real time IR preview on the LCD.

Here's an example:



Windmill
IR Channel-Shift Version
Canon Powershot G1
Shutter: 1.3
Aperture: F8.0
WhiteBalance: Custom
ISO: 50

BTW ... as I heard, it's possible to modify the G1 for IR too by removing the internal hotmirror. Then you can use an external IR pass filter for IR or an external hotmirror for standard color photos. I think, this is a great advantage compared to a modified D30/D60.

Yep and maybe there are people who are interested in the modification but only have one camera.

In this cases it might be worth a thought to replace the internal hotmirror with pure glass. Then it should be possible to use an external IR pass filter for IR works and an external hotmirror for standard color work.

But I'm not shure, if it's possible to remove only the internal hotmirror ... as far as I remember the CMOS filter is a combined filter. The second question is, if any of the available hotmirror filters is good enough to compensate the lack of the internal.

Roger,

The bayer filter is removed. If I left it in then the "blue" and "green" pixels would not be accurate. By removing the bayer filter every pixel is recording true IR.

By using CWB the image is recorded in B&W IR.
