hehe the bee thing was funny. very good video by the way. thank you

[Khorask]

Great tute.. very informative 

[binarygraphite]

@Khorask Thank you for the comment, glad you found it useful!

I can see the queen mary

[m3g1]

i didnt know we needed to have full light, or daylight.. i tried taking pictures today at 3PM and it was to dark :S i tried shutterspeed 30secs and F5.6

[binarygraphite]

@m3g1 It's still possible to take pictures when it's not that bright out but you'll either need to increase your exposure time into the minutes or increase the sensitivity (or both). Also, consider opening the lens as wide as you can to allow as much light in as possible.

[m3g1]

@binarygraphite hmm.. i tried at 30seconds shutterspeed and f.5.6 lowest setting i had and went up to 800ISO, still didnt work as well.. got slighty light.. but to dark.. what can be wrong? im thinking about trying again tomorrow.. strange =( what can be wrong? do u always pics on Manual or Aperture mode? maybe i should try taking pictures of something else? i tried taking the ocean and some mountains.. there wasnt that much light comming through the clouds maybe? =S

[binarygraphite]

@m3g1 It almost sounds like you're describing an image that has high contrast; tough to tell like this. I always shoot manual when doing IR work. If you want, feel free to send me an email with a photo you took and I can give you some quick feedback that way. You might just need to punch up the shadow areas using PS or other image editor.

[m3g1]

@binarygraphite thank you for your time.. what is your email so i can send u one photo.. ive only got like 1 visible photo.. which is pretty bad =( ive seen videons on youtube with people taking with their 18-55mm lens and IR filter and their pictures look awesome.. =S

[binarygraphite]

@m3g1 Glad to help! My email is binarygraphite at gmail dot com

[m3g1]

does this filter fit a nikon d5100 ? original 18-55mm lens?

[binarygraphite]

@m3g1 This filter comes in a variety of sizes so it probably does. But check your lens to be sure what size it is (should be on the front); I'm seeing 52mm according to Nikon's website.

[m3g1]

@binarygraphite thats right.. i see a 52 with a round logo and a straight line over. i dont know if its the size of the lens? hopefully it is.. hehe.. im about to order one now if it is =D

[binarygraphite]

@m3g1 That should be the thread size. Have fun with the new IR filter when you get it!

[m3g1]

@binarygraphite thank u for ur time =)

[WG02451]

Great explanation!  I just bought an IR filter and am still trying to play around with it to get the settings correct. This helps a lot!

[binarygraphite]

@WG02451 Wonderful to hear! Best of luck!

[RANGER724]

glad i found this, just starting out, perfect explanation to ir photography, thank you for posting!!

[binarygraphite]

@RANGER724 Happy to hear you found it useful! :)

[nesquikADDICTED]

Just one last thing, we focus first, but then putting the filter its pretty hard to put it without moving the focus.. $:

[binarygraphite]

@nesquikADDICTED Depending on the lens it can be a little tricky. This is especially true with some zoom lenses that move with little friction and lenses that rotate the front element to focus (versus the internal variety). But with a little practice over time this shouldn't be much of an issue.

[Mypsychedelicart]

The best Ir tutorial ever! Thanks, mate!

[moviemyles100]

press 4 and he says poo

press 6 and he has a spasm

[binarygraphite]

@uxa1 Depending on how sensitive one's retina is, along with the frequency of the remote's beam, I wouldn't be too surprised; one day I'll give that a try.

[123kgpsai]

Mr.Imre, what is the reason that our eye can not see that infrared light that is coming out of remote control but a camera can?

Thank you

[binarygraphite]

@123kgpsai Biologically our eyes are not sensitive to IR light, more specifically the rods and cones on the retina do not respond to light beyond the visible spectrum; humans are capable of seeing wavelengths of light between about 400-750nm. On the other hand, even with an IR blocking filter in place on most digital cameras, the sensors can pickup some near IR frequencies of light, like that of the remote control.

[bigjohnhaw]

@binarygraphite, Thanks, I will check your blog.

[bigjohnhaw]

Hi, I am using canon 50d. I just bought a ir filter of 950nm. I am just wondering how to set my camera. I tried to take pictures but the effects are reddish and too dark. If you could help me about my problem. Thank you very much.

[binarygraphite]

@bigjohnhaw Hi! This may sound odd, but you're actually on the right track. Having a red toned image is normal (similar to what you saw in this video and part 2); the filter blocks essentially all visible light except for the near IR spectrum. And since the image is too dark, that's because the image is underexposed. You could do a few things here, such as use a longer shutter time, open the aperture more, or increase the cam's sensitivity (i.e. raise the ISO) (or a combo of these).

[binarygraphite]

@bigjohnhaw I'd also recommend a visit to my blog as you can read the supplemental post there (there's an episode guide link off the main page). If you don't like the red tone you get on the cam after taking an IR photo, you could set the WB to compensate for it and I've written a little about it there. I hope this helps, good luck.

[nesquikADDICTED]

@binarygraphite I have a 950nm to and with F/4, 30 sec exposer, and 3200 iso Still doesnt look that perfect.. And if it did thats a pretty long exposer and pretty High Iso.. $:

Please repply.

[binarygraphite]

@nesquikADDICTED The one thing that comes to mind if you're not getting a great result with your camera and you require very long exposure times is that the IR blocking filter on your sensor is very strong. Therefore, the sensor just isn't picking up much IR light to develop a good enough exposure. If possible, you could try the filter on another camera or try a different filter altogether to see what result that provides.

[LaNiSgOkU]

what kinda lens do you use for these kind of photography?

[binarygraphite]

@LaNiSgOkU You can basically use almost any type of lens for IR photography. Some lenses may produce a "hot spot" or brighter circle in the center of the image, but for the most part the majority don't do this. I personally use my Zuiko lenses with a 67mm thread size (14-54mm and 50-200mm).

[wxb200]

What about presetting a white balance using a patch of grass?

[binarygraphite]

@wxb200 I'm not sure if a patch of grass would work or not as I haven't tried that method. In my blog I suggested setting the color temp as low as it can go (e.g. 2000K) which may help reduce the red tone; I neglected to mention in the blog that the green/purple color adjustment can be pushed into the green area, which should produce a more neutral looking image vs. that harsh red tone.

[JamesGreen321]

Another great video! I was wondering though, what difference in image is there between a 720nm and 950nm filter? Thanks :)

[binarygraphite]

@JamesGreen321 Thank you again! Based on what I know and seen the difference would be fairly small. Using a 720nm filter means you're not cutting out as much of the near IR spectrum; in other words, you'll capture light that has reflected off of things starting from 720nm and up. Whereas with a 950nm filter, you're deeper into the near IR range, thus you won't "see" light reflected off of things under 950nm.

[JamesGreen321]

@binarygraphite Thanks for the information Imre, I shall search flickr, I also have a flickr account if you use it also, my name is jamesgreen321 so feel free to add me if you wish! Keep up the good work :)

[binarygraphite]

@JamesGreen321 If you search Flickr for "720nm" and "950nm" you'll see the images look overall quite similar. Although I'm pretty sure that if you had two photos of the same subject, but one with the 720nm and other with 950nm, you could liikely pick out some differences.

[hairyferry]

Imre!!! Great Video! I prefer the unscripted versions! This is a great video, I'm really looking forward to the next one! Keep up the good work!

[binarygraphite]

@hairyferry Thank you muchly! Ha, I'll probably be doing more unscripted stuff as I get into Photoshop tutorials.

[hairyferry]

@binarygraphite When is the second part of this one coming?

[binarygraphite]

@hairyferry Hopefully in the next day or so.

[KennethKramm]

Useful. Your humor is similar to mine.....I like it!

[binarygraphite]

@KennethKramm Ha, thank you sir!

Another amazing video :) Very informative as always, Keep up the good work :)

[binarygraphite]

@robheald1 Thank you Robert! I'll do my best!

[seanyyg]

I'm glad you made this video. I was looking into this type of photography just the other day! Very informative, as always! Thanks :)

[binarygraphite]

@seanyyg Awesome and I'm glad you found it useful! I think you'll enjoy IR photography; has a different feel to it and makes for some very unusual looking portraits too.
