Infrared Photography

[PandaOng]

Hi,
Anyone got a copy of "Practical Photography" Nov 2004 issue? On Page 26 where Chris Rutter discuess on InfraRed Photography on Digital Camera.

After testing out if my camera has a IR-blocking filter with a remote control, I am sad to find out that it does. thus I am not able to create IR image on my camera

Anyone has other tips to get IR effects on DSLR?? help appreaciated.

What type of camera did you do the remote control test on? Most of the semi-pro DSLRs even though they may have IR blocking filters are capable of IR photography. It is just the exposure time used has to be longer, in the order of 10 -30 sec depending on the DSLRs.

Hmm,
is that so? Have try to capture with my Ixus 400, able to see the infrared after snapping. but on my DSLR, I cannot see anything. Maybe you are right. I will try on a longer exposure to be sure.

New to this IR thingy, Is there variation on the different IR filter?? if so, which one should I get? thanks for the help!!

There should not be a problem shooting IR with a 20D.

You will not be able to see with the IR filter attached to the lens, thus you will not be able to compose your shot. You should mount the camera on a tripod, compose, focus then fix the IR filter onto lens then shoot. This way after shooting you should be able to review your shot in the LCD.

Don't forget to do your preset white balance first before shooting.

A sample IR shot with the Hoya R72. There's some camera shake here 'cos did not use tripod.

i dropped my hoya r72 yesterday

the glass dropped out of the filter....is there a way to fix it back? or superglue?

There should be a retention ring to hold the glass. Did you lose that? If still available, pry that out and put glass in, then fit the retention ring back.

The different IR filters have different degree of opacities to visible light. As a general rule, the more opaque, the more expensive. For most DSLRs, the Hoya R72 which is the least opaque and the cheapest, would suffice. The Hoya R72 because it is least opaque can output coloured IR photos instead of monochromatic IR photos (with more opaque IR filters) if you so desire.

Also, just get the 58mm filter instead of the 72mm which is extremely expensive even for the Hoya R72. In addition get a step-up or step-down ring to fit the lens that you would be using. Because of the 1.6x multiplication factor on most semi-pro DSLRs, a 58mm IR filter can be used on a 72mm lens without any vignetting problem.

Whoowoo...You shot this with 20D?? Cool....IR...here i come. heehee

Sorry to have misled you, but the picture was shot with a D70. But you should have no problem shooting IR with your 20D.

Anyone tried Infrared on A80?

[aabels]

actually quite interested to get into this too, but heard that the Infrared Filter on some cameras, maybe can cause a bright spot in the centre area...something like an over exposure central portion right in the middle of the pic. anyone have experienced or came across this?...thks

This is done with A80.

[popeye]

huh? why the picture doesn't come out?

[tunster]

Saw it......how much you got your filter? Which brand?

[Witness]

so basically juz buy the filter ...put over then lens and take teh photo isit??

does metering still work in the d70 then???
haha....

looks cool le...

any ideal how much is the IR filter for a 77mm thread???

You need to do a Preset White Balance with the IR filter on the lens first.

Yes meteriing still works in the D70, but make sure you shoot is very bright sunlight. Take a look at my previous post in this thread, that picture was shot in Programmed Mode with a D70.

Here's another sample shot with the D70.
Nikkor AF35-70. Programmed Auto, 1/15sec, F/3.3, +0.3ev, ISO200, handheld.

hey nice photo! ive been trying to find pics of singapore in infrared. but cant seem to find them anywhere on the net.

i have attempted a few already so far....but results not there yet

care to show me (or the rest of us) more pics?

anyways i dropped my hoya r72...the glass is now loose...so i have to fix it or get a new one again

[Witness]

bring it to TCW and see if can repair...

so any ideas for 77mm thread... price...

and it seems tt doin IR require pretty long exposures ya..

Tnanks, I'm still learing to shoot IR.
As long as the glass is not broken, I guess it can be saved. As witness suggested, why not bring it to TCW, they may be able to help.
Here's another pic for your viewing, please comment

Witness - don't know how much the 77mm R72 cost, but as a gauge I bought my 52mm from CP at $35. So 77mm could be in the region of $50 - $55.
Yes, IR requires long exposures. That why a tripod is neccessary. Unless you trade off for a shallow DOF, then shoot wide open with very steady hands. Shooting at a smaller aperture will give you a greater DOF and the pics will be very much sharper. Wind conditions also play an important part in IR photography. If you shooting trees on a windy day, then your pics will turn out blur 'cos of the long exposure and the leaving swaying in the wind.

okie....thanks alot for the help..i'd probably get it when i am free....at least all my lens use a 77mm thread...so not so bad...

cheers..
