How do you take infrared with a D50?
>> britewire
infa red filter and very long exposure

Must...buy!

Epic awesomeness.
What filter did you use?

I've got a Hoya R72 infrared that I used to do some B&W infrared stuff with on film...do you need to use any specific settings for color on a digital?

WB set manually (this is a must!), Use grass or foliage (or bare skin) they all work decently.
The OP pic the red and blue channels were swapped in photoshop. (very typical IR edit) makes things look more natural.

how do filters compare to actually converting your body to IR?
>> ac !!VPzQAxYPAMA

Using an R72:
1. Costs about $20 per lens filter size
2. Exposures are slow as fuck because you're just getting the barest trickle of light through the lens' visible light filter and the sensor's IR filter. Think 1/5th at f/1.8 ISO400 in broad daylight at noon
3. Framing is tricky at best, since visible light is all but blocked through the lens
4. Focus is tricky, since IR focuses slightly differently from visible light
5. You can take the R72 off at any time and use the camera as a normal camera

Converting the body:
1. Much more expensive. Costs a few hundred bucks, I think.
2. Camera can't be used for non-IR photography anymore
3. TTL viewing works perfectly well
4. Quick exposures
5. Chance that the person switching your camera over will fuck it over completely and you'll be screwed out of the cost of a camera body.

Horribly. With filters, you need super-long exposures of 10 seconds or more, sometimes longer than the camera is normally capable of for proper exposure.

With a body that captures IR like normal light, most of the time you can shoot handheld just like in normal light at 1/15 or 1/30 or so, and get well-exposed IR shots.

(Basically, I'd recommend getting an R72-type filter and only go for a body conversion if you find you really, really dig IR photography. Like after having done it for a few months. Otherwise, there's a good chance you'll get bored with it quickly)

Actually framing is just a little harder - you have to do it before you put the filter on :)
Second, better to try to exclusively use ISO 100 on all your shots if you can, it keeps the noise to a minimum.

There are 2 ways to convert the body.
One is to do a complete conversion (IR glass replaces the high pass filter) and the other is a partial conversion (standard glass instead of high pass filter.)
HOWEVER the partial conversion requires you to use a filter from then on for both IR and normal photography.
The upside of this is that you can put different IR filters on (Cokin or Hoya etc) and get the effect you are after, AND it means you can use it for normal photography (you just have to place a high pass filter on the front of the lens to stop the IR light from getting in.)

Just as a side note, my 40D has been able to easily focus through my R72 filter, which I found out when I screwed up and pressed the shutter button down without turning the autofocus off!
Needless to say I was very exited when it beeped to say "Hey, I am in focus!"

Oi! What would this image look like if it hadn't been switched?
Tomato-red sky and blue grass? I guess?

I'm a slacker who can't be bothered with a tripod most of the time (which also explains the ISO400), so that's not really an option. I'd end up messing up my framing by putting on the filter.

What I do is keep both eyes open and tell it to autofocus. My Rebel lights up the center AF point and I know where the center of my frame is 'cause I see it sort of overlaid on what I'm seeing through my actually-has-light-available eye.

>Needless to say I was very exited when it beeped to say "Hey, I am in focus!"
Yeah, as I recall the AF system actually uses infrared light to focus normally, though don't quote me on that. The problem, though, is that it's calibrated for visible light. So the AF works, and if you take the filter off and take the shot with that focus it's fine, but the infrared focus is slightly off. On some lenses (getting less and less with time, especially at the cheap end) there's a little IR focus mark to tell you how to adjust the focus after focusing with visible light to get the IR focus. Or you can just stop down a bit so you get the whole thing in focus, but again, I go tripodless, so stopping down isn't a good option for me.

What's with the price for a 72mm Hoya IR filter on Ebay?! $145!!!
>> Jesus !1EQ.kCAg9c
>>157067

Mine was only $40...of course, I got it at 52mm since I was only gonna use it on my 50mm lens.

Can't even find a 52mm that cheap. Ebay sucks!

Just found this website that has a really quick Photoshop tutorial, I dunno if any of you want to try it. It's somewhat close to actual color IR but not quite, works well with some shots.

Photoshop hack ? real thing.

It works for most situations I guess, but if you show it to someone who knows about IR photography they'll tear your picture out of the internet and poop on it.

1. what's the purpose of IR photography? or is it that it just looks different

2. if you do the body conversion, when you check out the viewfinder, is it normal or does it look like IR?
>> Vincent !!8LCSE0Zp1mL
>>157339
Normal, We can't see the IR range of light (>720nm)
(well not much of it anyway)

Some people can see better than others, so if you have a filter you can test it out (not in daylight if I were you though!)

Unfortunatley I am a tightass who can only get lenses when they are uber cheap.
EF-S 18-55mm 3.5-5.6 II for AU$70
EF 35-80mm 4-5.6 USM for AU$20

Both used, both in perfect condition, however neither has an IR mark or focus window :(
