Right at the beginning you nailed the one thing I'd failed to grasp. Many people had talked about setting the white balance to the grass, but nobody had ever mentioned that you wanted to do it with the filter _on_...

D'oh.

WOW! very nice video tutorial. Great photographs with great results and explained very nicely. Makes me want to go out and try IR photography - if my camera will cooperate. BTW, love you accent!

Judi! You have a voice! Lol...I really enjoyed the tutorial not just for the IR information you provide but for the information you provide on post processing in general. It gives me a better appreciation for how much time and effort you put into the your images and makes me want to learn more of the PP stuff.

Thank you so much for taking the time to put this together!

Thanks heaps everyone.

21_F.gif TCGuru - Thanks heaps. It didn't take as long as putting together a written tut. I have 4 x 2 day courses printed in booklet form that I am hoping to put into video tutorial.

21.gif dknourek - Thankyou so kindly.

21.gif chimericvisions - Ahh yes...I thought they might help you.

21.gif Southern Gentleman - I hope you do have a go at IR work...it is certainly a completely different experience to normal photography.

21.gif Citadel - LOL...yes I do have a voice. I am please the PP was useful as I had hoped.

Excellent work Judi and i agree you have a great voice.

Brilliant tutorial.
Really cleared u alot of the questions i had about IR.

Thumbs up.

Excellent tutorial. It stopped loading about halfway into the tutorial, dodgy SA internet, so I'll try get the full version later. I've always wanted to try IR photography, but my lens leaves a big hot spot in the middle of the image. Good thing I made a filter out of E6 film to test before I forked out for the pricey filter. I'm planning on upgrading to a dSLR soon, so hopefully I get a lens that works for IR.

Wow Judi, you make it look so easy. Today is my day off from work and I know what I will be doing (if I can find some trees in Phoenix).

21.gif MichaelC - Hahahaha...I am glad someone agrees with me.

21.gif marbo - Thanks mate!

21.gif Ben - Hey, there's my Ben. If you have any other IR questions..just let me know.

31.gif Raziel - A lot of that can be alleviated by the time of the day and the angle of the sun. My Sony used to give the odd hot spot, as does the Nikon...but with a bit of experimenting it can be avoided. I hope you get to see the entire video soon.

21_F.gif BAMartin - Thanks Barbara....it is easy...just needs a little playtime. I look forward to seeing your results.

Great tutorial! This is the first time I have heard about Infrared Photography. Which cameras have this option?
03/05/2007 02:32:23 PM · #15
Great job!

True and false. Some bodies/lenses actually just have hotspots that are unavoidable. The Canon 18-55 kit-lens (when combined with the XT) causes nasty hotspots regardless of sun, but other lenses don't.

Some combinations are just unusable. I agree that Raziel should experiment, though.

It's slightly more than the odd hot spot, I can't get rid of it.

I've read somewhere (can't remember where) that some lenses has a hot spot due to the coating on the lens. They weren't designed for IR photography. I will definitely still experiment, but only once I upgrade my camera and try out another lens. The filter is fairly expensive and the camera's IR performance is not good enough to warrant it. The lack of any real way to manually focus also makes things difficult. I'm planning on getting a Nikon, and will try pick up an old prime that has the IR focusing marks on it. My theory is that if they give focusing marks for IR then it should work with IR.

Here are two quick examples of what I mean (straight from camera expect for resize and save for web).

f/5.6

As you can see the spot gets less as the aperture stops down. There is also a bright spot in the top right hand corner, though I suspect that has everything to do with my makeshift IR filter.

I just got back from a IR shoot, and I am a little disappointed to say the least. I set the custom white balance and the photos straight from the camera are no longer red.... but when I swap the red and blue channels, they are overwhelmingly blue. Ack, back to the experimenting for me. At least I did not have a hot spot this time, that might have been a function of the sun and the time of day.

Funny you should mention this. I was using my IR filter and that lens/camera last night. The hotspot was there but when I made exposure much longer it went away. I haven't seen it though with my other lenses.

21_F.gif daboardergirl - Welcome the IR. The Nikons are great for IR work as are a couple of other smaller digitals. Check out 21.gif Marbo for his cameras.

21.gif breadfan35 - Thanks heaps!

31.gif Raziel - Ouch!! That does seem harsh. I do agree that part of the problem is the makeshift filter. Is there any chance anyone nearby has a camera and IR filter that you can try your lens with, to try and alleviate if it is the lens?

21_F.gif BAMartin - Okay...you need to be positive here. It does take some practice and when you look at it...you have taken a step in the right direction. Can you show me the images. I have some meetings this morning but when I get back I can work on what you have and help you.

21.gif mad_brewer - Ok...so now you can see what I mean by expermenting....with this work, each image is different...it is a matter of trial and error.

Infrared can be very time consuming, frustrating and yet it drives you to keep going, because of the rewards at the end. Keep trying everyone.

I have just added two more IR images to the collection.

I don't know anyone down here who has a IR filter. Not even possible to test it out at a camera shop. Only one of the shops really knew what I wanted and they will have to specially order one for me if I want to buy.

I really doubt that the centre spot is due to the filter. The spot gets smaller as the aperture gets smaller, the aperture of the camera is also circular, just like the spot... The spot is definitely causing a loss of sharpness, two layers of E6 film sticky taped to my filter adapter can't do any good. Will keep using the film to test lenses until I have one that works, then I will buy a filter in that size.

If the colours come out looking weird you could always convert to B&W, the traditional way of doing IR. Colour is how we see the visible part of the electromagnetic spectrum, IR has no colour only intensity. The colours you get in IR photographs are just how the camera's interprets the light it sees. Once you get the hang of it you can move onto false colour IR.

nice tutorial, judi. very through...

actually... i got a lot of good photoshop tips from it out side of the ir work... worth watching even if you're not planning to do ir...

Thanks Kudzu....that seems to be the main positive of the tutorial. That's great to hear that it can help others.
03/05/2007 05:12:50 PM · #24
Thank you, Judi ... You are a true sharer. What a very nice gesture from you to share knowledge that must have taken you a considerable amount of time to accumulate. I learned a lot from this tutorial and not only (as mentioned here above) about IR photography but also general PhotoShop manipulations.

Edited to correct typos and grammar ...
