Infrared photography
Old Nikon D90 is old but still works. 50k exposure on the body. Nikon believes 150k exposure life expectancy.
Thinking about having life pixel convert the D90 to infrared.
Has anyone done the conversation?

I haven’t had the conversion done myself, but I’ve got a 40D I bought pre-converted. It’s fun to play around with if you have the means to convert a spare camera.

doesnt infrared shooting change the way focusing works and it gets all jumbled up? whats with that? is it some meme from old geocities pages?
>>

Man that is a funky photo. Reminds me of miniature photography like for train sets. Not sure why. Probably because of color and lighting for those sets being odd and unnatural like viewing that image.

Damn, my camera won't last very long if that's all I could take. Like less than 4 years.
>>
>>3195048
Speaking of infrared photography is it easier to do it with film or a normal digicam with an IR filter? I tried with my 700D and the results were really meh, I'm thinking of buying some IR film and trying that out
>>
>>3195057
Don't bother with ir film.

Yes, infrared light focuses slightly differently from normal visible light. If you have an IR camera with live view, you can manually focus it using live view and it’ll be accurate. Otherwise, you need to either focus normally and then adjust to the infrared equivalent focus (higher end lenses will have a little red dot to tell you where that is) or get your AF system modified to focus to infrared with one lens and just use that lens.

You can try Owax IR film, it's a really good hand rolled IR film. And not that much expensive (22$ for 36 exp.)

Here's some picture I've done with a G7 and a 25mm 1.7

What visible light filter should be used?

These are beautiful. Well done.

>>3195057

I tried both the ilford sfx 200 and the rollei infrared film. They are fickle, fog easily, and aren't very fun. I didn't like infrared until I got a converted digital camera.
>>
>>3195293
When they convert a camera to IR, they usually replace the IR cut filter with a visible light filter right over the sensor so you don’t have to worry about that unless you go full spectrum (or you mean what filter to use for an unmodified camera, in which case Hoya R72 is what I used to use and it was fine).
>>
>>3195258

This is a hypothesis that doesn’t actually stand up to any significant scrutiny unless you’re high or a fourth grader.

No one ever wonders if the C# I hear is an F two octaves down that someone else hears, but that makes exactly as much sense as the “I wonder if the green I see is what you see as red” idea.

How did you get these colourised? when I tried doing IR on my 700D all I got was purple images. I used a 850nm IR filter.

850nm is too deep into IR for false color. Get the "standard" 720nm filter.
Oh wait, is this not a full spectrum camera?
>>
>>3195371
>>3195443
Because I'll likely forget all about this thread, if your camera is converted to full spectrum use something like a 695nm. This will still let in a bit of color giving you a lot of room to play in photoshop. If unmodified camera I *think* a 720nm would work better. Not sure how much visible light your camera will pick up with that.
Good luck.

>>3195325
People who are color blind, tone deaf, or do drugs kind of piss on that hypothesis. Lots of people wonder that. We will never actually know. We can only look at stuff like how cones and rods work in the eye, but not how the brain interprets that data.

>When they convert a camera to IR, they usually replace the IR cut filter with a visible light filter right over the sensor so you don’t have to worry about that

So, I just need to open the DSLR, remove the sensor glass.
Cut one visible light filter (would this Hoya R72 be fine?) to the same size, and replace it on the sensor?

Should try it with some actually good subject matter/shots and on a still day.

I would guess it’s more complicated than that. Google around a bit—I’m pretty sure there are online guides for how to do the conversion yourself.
>>
So does IR video work the same way then? Just remove the filter and you get IR?
>>
>>3196274
Was it film ?
>>3196291
Imo yes. Search infrared video you'll find some defiltred camera that shoot video
>>
>>3196305
I see more IR video with just black and white rather than the types of color I see here. I'm assuming that's due to security cameras that specialize in IR video. But what's the difference between security camera black/white IR versus IR from a converted camera Another question is that since the IR filter gets removed, is the digital sensor more prone to damage from UV light (as in are the IR and UV filter on the same filter and both get removed during the conversion)?
>>
>>3196305
No unfortunately, most of my other school work was black and white film.
Wanted to make my digital work more interesting so I chose to do IR and long exposure stuff.
>>
>>3195048
>>Has anyone done the conversation?
Man posted they got their cameras converted, none said who did the conversion

So has anyone done the life pixel conversion?
>>
>>3197681
I bought a converted one on eBay. No complaints. There's a $20 ir lamp by Kodak that you can get on Amazon. Works pretty well with it. I haven't made any art with it yet, but I did have a fun few days playing around.

These frames are black, but transparent to ir light.

Why would you need an IR lamp?
Just for indoor IR photography?
Is the light from a speed flash full spectrum?

You know what? I don't remember trying it with a regular flash. The ir lamp is continuous (and the camera is live-view only) so composing is a little easier. Plus you get a cool ghost hunter vibe.
>>
>>3200719
>Is the light from a speed flash full spectrum?
Sometimes. Conveniently, the shitty cheap flashes are more likely to be full spectrum, since filters to give you pure visible light is one of the many corners that Chinese companies like to cut.

Humans are not capable of infrared vision in the eyes themselves, but some animals do have other methods of absorbing light. IIRC, infrared exists in some snakes and possibly some deep sea fish. However it's more "sensed" independently than seen.

Many various birds have ultraviolet receptors in their eyes, and it is believed Van Gogh for example could see UV after an eye surgery. It does change the way you see colour.

An old boss of mine (red) colour blind. Said it appeared more as a dull brownish grey, and certain other colours (E.g. green) were not as "vibrant" as in other people. He was of course basing this on description and reaction from other people, not his own observation. If we made presentations where he'd be present it was something we had to consider.
>>
>>3195325
But I do see color differently anon. My colorblindness just makes it difficult to distinguish light shades of red and green though. Worse, not better colors.
