Infrared Help Please (2 pics with 5700)

I've seen some good looking IR shots on pbase, so thought I'd take the plunge. Purchased a Hoya 67mm R72 filter for my 5700 and used the Nikon adapters that I already had.

The first thing I noticed is that BOY, IS IT DARK with the filter on. Today, I went to friends house at the lake and took several pictures in the bright sunlight, and used exposure times of 1/2 to 1 second. I'm linking to one scene taken with regular lens, and the same scene with IR lens. To me the IR photo seems to be not in focus. Is that because the there was a slight breeze, or am I missing something else.

I've processed each photo in PS7, using only Auto Levels (on both), and USM of 100/2/1 on the 'regular' photo. I then resized them.

Oh, I also noticed, for the first time, that I have several hot spots in my camera.

Any suggestions, comments, etc are welcome. Thanks,
Ted

Re: Infrared Help Please (2 pics with 5700)

Hey Tevern, try this next time, focus your camera first with out the R72, once its in focus hold the shutter 1/2 way down to lock it in focus, now screw on the R72 and take your shot. That way its in focus. Make sure you're using a tripod and remote. If you don't have a remote use the 10 sec. timer. You may need to lighten the photos or contrast in Photoshop ......Richard L.

Re: Infrared Help Please (2 pics with 5700)

You can take sharp pictures with the R72. You have to be very careful about wind or vibration during the long exposures.

A tripod is manditory. I've found either the remote or using the timer is very helpful and avoids shutter press shake.

You can either prefocus as Richard mentioned or use the Mountain setting for landscapes (this seems to work well).

I usually take quite a few images of the same scene to make sure at least one comes out well.
Here are a few that worked.

Re: Infrared Help Please (2 pics with 5700)

Ted, I also use R72 with 5700 and indeed it is a difficult combination :). Your sample pic looks exactly like what I shot when I got R72. Somehow pre-focusing did not work for me therefore I try regular autofocusing if light permits. Or some times I also use manual focus (10 clicks backwards from infinity). You can also brighten the LCD to make the scene more visible when R72 is screwed on. Just couple of months ago I got 89b another filter which is not as dark as R72. Using this, I can also shoot IR in non-ideal light/situations.

You can see my R72 IRs at http://www.pbase.com/kmahbub/infrared and 89b IRs at http://www.pbase.com/kmahbub/color_infrared .

Hi Richard,

I certainly can't argue with you when you have shots like that. I'll give that a try tomorrow.

Thanks,

Re: Infrared Help Please (2 pics with 5700)

Scott,

You have some nice shots out there on pbase. It's encouraging to see what is possible.

I did use a tripod, but not the timer. I'll give that a try also.
Thnaks,

Re: Infrared Help Please (2 pics with 5700)

Kamran,

You've done a great job with your IR pictures. I'll be back with some more later. Thanks for the tips -- and sharing what is possible with the combination. I may try the 89b later.

Re: Infrared Help Please (2 pics with 5700)

Kamran,

What is the difference between the R72 and 89b filters? When I check http://www.pauck.de/marco/photo/infrared/filter/filter.html , I read that they are comparable. Another web site, http://www.wrotniak.net/photo/infrared/ , also suggests that they are similar. Yet your [very impressive!] pictures show quite a difference.

Can you (or anyone) direct me to a web site that had the transmission spectra for these filters? And, where did you get your 89b filter? And, what processing did you use to get those neat colours in your 89b-pictures?

Thanks

Re: Infrared Help Please (2 pics with 5700)

A couple of things I found helpful using the R72 and the 5700. Turn off auto contrast, reduce saturation and turn off sharpening. Take test shots of the same scene with different levels of contrast and shutter speeds to find what works for you. then process after. A washed out looking photo can be dealt with easier than a blown photo so seek to reduce the blowouts. Also I use a cable release and braket exposures. Here's some I posted in Samples and Galleries a few days ago. The first was taken in shade and the second was behind the first scene in bright light. In fact it is the bright area in the center of the first. All these are with this camera/filter combination. All required post processing. Good luck with your efforts.

A couple more.

Re: Infrared Help Please (2 pics with 5700)

BTW, I always use auto-focus with the filter in place.

One thing I didn't see mentioned is...

Use the noise reduction feature since your exposure is slower than 1/30th second AND use a smaller aperture. I would use f8 or smaller.
Why?

Well because Infra red had a mush different focus depth. The small aperture will help correct that.
Also avoid using much telephoto for the same reason
Good luck!

Re: Infrared Help Please (2 pics with 5700)

ookpik, I also read that misleading text somewhere on the net when I was buying R72 (and 5700). Anyway, now I use both the filters, and for sure they are different :). R72 is much darker than 89b and filters different wavelength.

Re: Infrared Help Please (2 pics with 5700)

Thanks, Kamran. This confusion between R72 and 89b shows up quite a bit. As your pictures show, there has to be more than just a label. The "R72" designation seems to be associated wit Hoya and it appears that it blocks all light below 720 nm ( http://www.besoptics.com/html/hoya_infrared_transmitting_fil.html ). But so, apparently does the 89b (

). Then,

shows a threshold for a "B&W 89b" around 690 nm. Is it possible that all "89b" filters are not created equal? Which reminds me, where did you get your 89b filter?
Thanks again,

ookpik

I guess it's very much possible. I bought mine from Harrisson & Harrison. The build quality of the filter is not as good as that of Hoya, but still works for me. They manufacture filters in their own lab (sounds a small company). Therefore it's possible that it's not actually 89b (They called it 89b so I call it).

Re: Infrared Help Please (2 pics with 5700)

Kamran,

Curiosity got the better of me, so I e-mailed H&H. According to one of them, Will Harrison,
"89-B: Absorbs visual below 670mu (Passes 30mu of visual)

"88-A: Absorbs energy below 710mu (Cuts all visual + 10mu of the near IR equal to the R72)
"87: Absorbs energy below 730mu (Cuts all visual +30mu of the near IR)"

Not sure of the units used by Will, but there appears to be a "50 nm window" between H&H's 89b and Hoya's R72. That would make the R72 more of a "true" IR filter but, as your photographs show, the 89b may be more suitable.

Kamran, could you give me a link to Harrison & Harrison. I have been interested in a 89b and can't seem to find one that will work. I have a 67mm lens adaptor for my filters. If I can't find the right size, I may have to get a step ring.

Thanks in advance.
