What a great tutorial, you make it easy to understand & follow. You did an amazing job! Do you have any others on here? I'm going to look & see.
Thanks! |

trevytrev, thanks for the information...that's exactly what i did...use the histogram to check exposure...i just thought there must a better way of doing it than eye-balling histograms...
In the mean time, I don't think I would like to touch my camera just to be able to get a faster shutter speed for IR...ha ha...

Some cameras are better for IR work then others. The canon cameras have a strong hot mirror in front of the sensor that blocks a lot of IR light so the shutter times increase in order to compensate. I used a filter on my 20D and 30D and the shutter times were just to long with results less than satisfactory for my liking. Some Nikons handle IR photography much better b/c they do not have as strong of a hot mirror letting the user handhold the camera at much faster shutter speeds. As for the shutter lenghts and exposure, you are going to have to play around and expirement to find what works best for the situation. I would suggest you use the histogram to make sure you have a well exposed shot, not the LCD.
You can also have your camera modified by companies to remove the hot mirror, this enables you to use the camera at fast shutter speeds meaning you can handhold. I used Life Pixel for my camera and I am very happy with the results. One you have it converted your camera, it is no longer good for normal photography purposes, and it's a bit pricey. Hope that helps a bit. |

judi...that was a very nice tutorial. I learned a lot by viewing it.
I am new in infrared photography and recently bought the hoya r72 for my canon 1DM3 but do not know exactly how to use it yet. I did experimented a few shots and found out that at IS0 800 and aperture opening of f/5.6, the shutter speed is really slow as in 5 secs or longer. The image taken was a landscape and taken in a very bright sunny day.
What ISO do you recommend? How do you meter the scene with the filter on? Is the exposure done by trial and error? Exactly how long are your "long" shutter speed? 10 sec? How can you take a photo of a person (like in your example, the man with the motorbike, your daughter, the old man with the child) in low shutter speed and still expect these people to hold really still?
Any tips will be greatly appreciated. Thanks.

Dear Judi,
I appreciate your tutorial in infrared photography very much. This video helps a lot of people who want to learn infrared photography, but they don't know how to start. I am the one of them, either. I tried to shoot infrared photograph, but I found the result was different from your shoot. I didn't know why it was.
I didn't remove the IR cut filter, and I used Hoya R72 filter . I wonder how to set custom white balance. I set the custom white balance method that the D70s shot grass. Did it has something wrong?
The attached file with my infrared photography has sent to your E-mail ijudi@judigraphics.comj. Please help me to check what the wrong is. Thanks a lot.
Looking forward to hearing from you soon.
Best regards,
Tao

| Citadel - So far, I've had good luck with the kit lens (18-70) on my D70. I'll try to use my step-up rings and try all my other lenses to see how they fare. The next couple weeks are pretty busy, but I'll try to post some examples when I get the chance. |

| Lenses and IR are a crapshoot. Some very good lenses don't do very well for IR work, because they display a "hot spot" in the center of the frame that's caused by internal reflections. There's no easy way to tell what's good and what's bad except to rely on the experience of those who have gone before you. You've now tapped my knowledge, because I have not shot IR with my Canon glass. |

Just out of curiousity, is there a particular lens you get better results with? Or certain features of a lens that are desirable? (e.g. One with a large aperture) or will any lens do just as good of a job as the next one? (if said lenses were comparable in the regular world that is).

| Yep, the R72 has a much shorter-wavelength cut-off than the 093. It does let in some red visible light, though very little. On unmodded cameras, the R72 is definitely the recommended filter. |

| Thanks for the quick reply Judi. After looking up the stats and comparing the 2 filters, it appears that the Hoya filters out up to around 700nm while the B+W goes all the way to 1000nm. Since visible light stops at somewhere around 600nm (if my memory serves me correctly), your filter might be letting in some near red color that allows you to have some color on only certain subjects or parts of the image. Hmmm, I guess that means I'll be investing in another filter. |

I'm using the B+W 093 IR filter. I can't seem to get any of the color gradients you are achieving. Mine either some out red and black without white balance or completely black and white with it. This may just be due to the filter since it blocks out to 900nm of light and visible spectrum stops at 600nm. However, if you have any other ideas why it might be I'd love to hear them. Thanks again for posting the tutorial. |
That look awesome Tony. I might be wrong...but I have heard others speak of big differences between filters on the same camera. Maybe someone out there has tried both your filter and the Hoya R72. I personally am not familiar with your filter. Where I live we cannot see any products...everything has to be purchased online....so I can't even try it out for you. Sorry.
Bear....thanks...glad you finally got to see it. I thought all my work for you was for nothing when you didn't say anything.

Sorry Judi; I hadn't been following this thread because there WASN'T any way I could make sense of it. I happened to look in and saw your note :-) Thanks VERY much for taking the time & trouble to accommodate the hearing-impaired among us. Even if I'm the only one :-)
You did a very good job!
Robt.

| I have collected MANY infrared tutorials from the internet in order to learn how to do infrared. I must say that this is the BEST that I have come across. Judi, if there is some way, I would like to buy a copy from you. Congratulations on your excellent tutorial. |

Thankyou to Langdon...you can now download the text version of this tutorial. So Bear...that should help you.
Just a note...it has been typed word for word to match the video tutorial. The images are just based there as a guide to help you follow along with the tut. |

made it through some so far and looking forward to the rest soon judi. thanks for taking the time. Although i have gotten some nice images in Ir I still need to do it consistently. Yesterday I ordered some ND filters and the like with a Cokin system and I also got a IR filter for the Cokin system. I hope it works well. I am excited to now be able to take Ir shots in different focal lengths other than 50. (I also got a Tamron 17-50 2.8 yay) so this weekend = Elvis taking wide angle Ir shots and learning to use ND filters. yay!
for the record if the new filter works well for me I will be selling my current hoya filter. |

| Excellent job Judi,I've been waiting for this since I read the original thread,thanks. One thing I don't understand is setting the custom white balance if you have time could you walk me through the process. I assume the D70 and D70s both work the same when it comes to IR? |
