vortex - my opinion, this is clearly a case of wrong WB.
Can do some salvaging, here's my try with one of your pics.

You are using a Nikon Coolpix digicam right?vortex said:
The pics don't look to me like they were taken with Preset WB. My pics when taken in Preset WB on my Coolpix 950 has a light pinkish cast and not such a dark pink-magneta cast.
Also for my Coolpix, even with Preset WB, the final post-processed IR images did not exhibit the kind of colours that could be gotten with the Canon DSLRs.
This is an example of the type of coloured IR I got from the Coolpix 950:

yea its taken on a coolpix.
for these pics...they were taken on sunny and auto wb i think.
i tried preset before....and they came out b/w looking.
i was reading the wratten 89b filters isnt as dark as the r72...do u think it might be better for the coolpix?
i hope i wont have to go the dslr (for now, at least) route to take ir pics, as i just bought the coolpix only. :sweat: :sweat: :sweat:
thanks again guys!
hopefully can learn from you guys this weekend. so is it confirmed yet?

The Hoya R72 is a Wratten #89B filter.vortex said:
The Wratten ratings are used as an accurate way of specifying the spectral characteristics of filters regardless of manufacturer. Other brands with similar spectral characteristics to the Hoya R72 ie Wratten #89B are B+W 092, Schott-Glass RG 695, Heliopan 5695/569, all of which are much more expensive and difficult to get locally than R72.
If you want to try a filter with is not as dark as the R72, you would have to try Wratten #25 (Hoya 25A), #27 & #70 in ascending order of opacity to visible light. I am not sure if this would help though as the response to IR seems to vary from one camera to another. Nowadays, some of the newer digicams are designed to be totally opaque to IR and so can't even be used for IR photography.
At least your Coolpix can still respond to IR at relatively fast shutter speeds. Worse come to the worse, you could still produce the more traditional B&W IR images with your Coolpix.
yes, I agree. It's brilliant idea. However, i found that the pix were not sharp and crisp as it had been taken with R72 glass filter, correct me if i am wrong. i heard that if we use two strips of processed but unexposed 110/120 slide film, it will produce same effect, had anyone tried that before ?
Might be 2 reasons for it.
Firstly I didnt sharpen the photos, save them and sharpen u will see the difference.
Secondly using this method if its not bright enough the camera will need a longer shutter time about 1/3-1/15 to get the correct exposure so you need a steady hand or a tripod. The second photo was shot at 1/15. I could have bumped up the ISO a little though.
Yes I heard that unexposed slide film also produce the same effect. The 5.25" discs are not easy to find though.

JaGr - interesting experiment that you've done using floppy disk to shoot IR, but like IRman mentioned, not too sharp. Sharpening may be able to make the pics sharper, but wouldn't it become more noisy? Could not save your 2 pics to try sharpening, don't know why :dunno:
tomcat - you must really be into IR photography. Having done so much read up on IR filters. If you're available, come on, join the group for the intended get together and discussion. We surely can learn from you.

Normally I set my ASA to 64, using RM 90, most of the time I got 1/30 sec f 2.8, pictures turn out good, clean and sharp crisp. Sometime due to its " too clean , too sharp " effects, it lost its creativity compare to films, that's why I shoot more on films to get the halos effects, and use 828 as standy option. Itried using higher ASA but seems like not much differrent in terms of gaining more speed.

Hi, teerex, tomcat and all.
Using a Fuji S602 and can't seem to get anywhere IR wise.
Teerex I have become interested in IR since I saw some of your takes a little while back.
Here is my try ...
If the S602 is too limiting for IR and not simply my lack of ability, let me know as I will change it :think:
Thanks guys.

Good attempt Pablo, IR effect is there. The pic lacks sharpness, especially the trees and plants. Looks like your point of focus is on the building.
What's was your aperture and exposure time? It could be a large aperture and lack of DOF that makes the building sharper than the foliage.
But still it's a good try. Keep shooting, use a smaller aperture for greater DOF. Look at the pic that tomcat posted in the other thread "Infra Red 20D", how sharp they are. Wish I could shoot IR as sharp as those. I'll keep trying too.
Nice to know that more people are getting interested in IR. Wish you could be here when the group meet up for discussions and shootings.
BTW guys, when's the meet up? Can we confirm this.
