[IR] Matilda Bay - Winter in Summer

[adam]

Went to Matilda Bay yesterday to take some photographs of my friends.

Had a chance to play with my infra-red-modified camera and am still very intrigued by it's effect (as when I first started playing with IR a few years ago).

#1


#2

Gorgeous tones in both shots. I love the composition & subject of the first, it's beautiful.

Would you mind sharing your PP technique for these? I'm an IR beginner and hoping to learn

Hi Rooboy

I did something very similar to the steps as described in http://khromagery.com.au/digital_ir.html under "Processing false-colour Images". I didn't need to change the white balance (as I shot in JPEG and had already set the custom WB), so I just changed the levels, swap the red and blue channels (to give that blue sky), slightly adjust the hue (on the bench photograph) and a slight change in the curves.

I saw your IR uni pics with the 12-24. I suppose you used similar PP steps? Looks good

[DaveB]

They're both very good Adam!
I do like the 2nd one a lot with the orange highlights (I presume those were blue sail covers in the original).

As for PP techniques, there is a direct link to the relevant section of that article. If you have Photoshop CS or CS2 you can download the action from there, check out how it does things, and try your own permutations.

I love both of these shots.

The clouds in the second shot are spectacular.

HolySh**** the first is fantastic. Well worth the cost of the camera conversion.

Is all this possible with just an IR filter on a DSLR?Rooboy I'll search yours I guess.

Thanks for sharing.

These are really, really cool. Really.

How come my IR shots don't look like that???

Nice work.

I've always loved the unatural look of IR shots .... In this case I preffer the first of the 2.

In most cases yes it is possible to take IR shots on an unmodified DSLR with the use of a screw on lens filter.

But how effective it is depends on how strong the IR filter on your cameras sensor is (this one actually reduces the amount of IR hitting the sensor).

So depending on your camera you may need a tripod even in bright daylight.

Glad to see you out having fun with the new toy.
I also realy like the way you have done #2. That is a great sky.

Wow #1 is fantastic, I love the surreal winter look. #2 is quite something as well. Post more

Woderfuuuuuul!

Is there a way to modify my D70s for ir shots?
(i have a hoya r72 filter)

Yes, you can remove the internal IR-blocking filter and replace it with R72-equivalent glass. This is a semi-permanent mod though.
For background information you should read around on the 'net, including this page at my site.

With DSLRs I'm not taking on any more R72 conversions, sticking to the B&W "87C" conversions. I suggest you look at LifePixel in the U.S.
You can send your D70s to them for conversion and calibration, or you can buy the filter if you'd like to try it yourself.

Last night on my way to Melbourne I realised that...
this is DSLRusers forum, and these pictures were taking with a compact camera...! I hope it is alright

Thanks for looking at the pics I'm enjoying this camera so much!

[Heath Bennett]

Great pics Adam.

Has anyone got any opinions on the Hoya 77mm RM90

I haven't used one myself, but I suspect it won't produce a useful image with an unmodified D70. It only starts transmitting around 750nm, and slowly ramps up, reaching 50% transmission at around 930nm.
The only reason the R72 works OK with an unmodified camera is that its transmission profile overlaps slightly with that of the internal IR-blocking filter, producing a slight "hump" above 0% transmission in the low-700s. With an RM90 I think you'll just get 0% all the way.

There's a useful interactive graph of the transmission profiles of many IR filters at http://www.eazypix.de/ir/filter/filter.html.
