Which IR filter ~ R72, ELP, Hoya 25A? [limwhow]

[limwhow]

Hello, kuanwk.
Thank you so much for coming on board and sharing with us your comparison.
Have you any more comparative photos between these three filters? If so, may I ask if you could post some more here?
Would certainly like to see more examples for ourselves to discern the differences between them.

It is a bit hard to get the Hoya U-360 or U-330. You can try checking out Edmund Opticals but the size is an issue IIRC. The most easily available UV-pass filter is the B+W 403 but it leaks a lot of IR also. So you will need an IR-cut filter to remove the IR contamination.

Thanks big bro Francis247 for your info. Just to share my finding:

i saw an interesting read on "Dealing with the Infrared Contamination of Ultraviolet Photography" @ http://www.beyondvisible.com/BV3-IRcontamination.html

I also dug out 3 very interesting ancient threads discussed by you and other Infrared-Clubsnap seniors/members:

1.) thread posted by senior CS-member tomcat @ http://www.clubsnap.com/forums/showthread.php?t=211908

2.) thread posted by CS-member regit @ http://www.clubsnap.com/forums/showthread.php?t=127772

3.) thread posted by Wolfgang Steiner (he was deregistered but his blog about UV photography is very informative and interesting) @ http://www.clubsnap.com/forums/showthread.php?p=2471471

Hi Francis, there's a lot of equivalent filters available in China.
They got a complete range (more than Hoya) Here's a link with cross reference:

Some suppliers have different filter thickness available

Fantastic comparison! Well done!

My work place managed to get hold of a UV-pass filter from Schott called UG 300 (or something similar), I think. It came from RMIT University where they have a scientific photography department. It transmits only UV, and it looks like a rainbow coloured mirror, but unfortunately too small (below 52mm diameter) to mount on most lenses.

We modified a Nikon D70 for full-spectrum so that we can use any IR or UV filters, but somehow the UV images look very bland or washed out. Exposure times are also quite long. The ozone layer blocks out most of UVA, and glass blocks out most of UVB. In theory, mostly UVC gets captured but as you know UVC is commonly used in medical sterilisation equipment.

Just wondering why do one need so many type of Ir filter... Wat ever color we wan can alway get from the Photoshop... ist? Newbie question hehe :bsmilie:

 

[limwhow]

Hi bro fatigue, how about Goldie IR using the Nikon 056 and Nikon R60 filters?

Another interesting info by Bjørn Rørslett @ http://www.naturfotograf.com/irfilters.html

SurrealDreamWalker, thanks so much for coming by and posting this very interesting link.
Looks like you are exploring this realm of UV photography and I sincerely hope you would lead us again in this UV realm!

Fantastic comparison! Well done!

Hello, Jemapela. Thank you for your encouragement!
I will certainly need to tap you experience in portraiture photography. My IR portrait PP is a little too plasticky I feel.

Hello, Netbaby. Thanks for coming by!
It's a very very small comparison only. Nothing much.
I just hope I have not made too many erroneous presumptions here and as I have mentioned, I would welcome any corrections and/or added pointers like what Francis247, fatigue, kuanwk, SurrealDreamWalker and Jemapela have all given!

Hello, Lx3Chua. I agree with you that we certainly can PP on some colour. But if we use a high cut-off filter like a Full IR, it would have lost so much intrinsic colour that it may be difficult to regain some natural hues from the photo.
Of course, the other reason is the use of a filter that is appropriate to the user's own IR style will mean lesser time needed to do PP.

You are welcome, but definitely you deserve the compliment for your effort.

You give me too much credit. I don't consider myself fantastic at portraits, and I haven't done any serious portraits for a long time. I have moved away from the creative aspect to the technical aspect. Everyday I fondle DSLR cameras and lenses... I repair/modify them as a day job.

Anyway, I believe some post-processing methods are intended to look plasticky, hence it is up to the individual to not use it and change to another method.

Thank you very much, hkingx!
In summary, as a very general rule:

• If you would like your foliage to be snowy white - R72 (whichever brand) with a cut-off at 720nm will be your choice.
• If you like golden yellow foliage - then Edmund Long Pass ELP (again, whichever brand) with a cut-off at 680nm will be good for you.
• After you have played with IR for a little while, you may venture into IR filters with much more colours. Goldie IR, Hoya 25A, Fantasy IR, Full IR... all these are fanciful and very poisonous IR filters that all the experienced IR shooters in this IR sub-section are very well-versed with. They have much lower cut-off wavelength and are very useful in shooting IR portraiture as well.

Now there is addictional 12 filter types for colors infrared. It's make the post processing less tedious and you begin to experiment with post processing.

Thank you for these great comparisons bro. Surprisingly, while I'm dying to own an elp filter, looks like the r72 gives a nicer skin tone after masking. The 25A seems too be an interesting filter too but I thought it looks very saturated.

Most exciting, airforce1!
Certainly the more colours the easier to PP.

Well mabmy, I think the saturated look is probably the way I PP-ed them.

I have did a search on which IR filter and so far this seems to be the only one that did a comparative review between R72, ELP.

How about Corkin P007, Lee #87 polyester, B+W IR092 and IR093?

It seems like each gives a unique IR "colour" which is inclusive of the camera used...hmmm any suggestion? Right now I am using a D90.

Cokin P007 - More saturated colour

Lee #87 - BnW

Not too sure about B+W but I believe B+W IR093 should be BnW also

 

[tsk1979]

Wow, what a post. Thanks.
I am currently on a 760nm filter. I want "more IR effect" than the 720 gives me.
850 was a little too strong, but 760 should be the sweet spot.

They are certainly informative for us who are still playing with our various filters.

Thank you Francis247, for adding on more information for all of us here who are keen on trying out other different IR filters.

Thank you tsk1979.
Your 760 would definitely, like you said, give you lighter hues with more contrast.
