Canon 5d Mark II Infrared Test

[misterx]

It seems the 5d Mark II is slightly less infrared sensitive than the Mark I, but with suitably long exposures I was still able to get some IR magic. Usually I convert IR to monochrome, but for some reason I was really digging on the hues the filter was producing, so I desaturated them a bit and went with it.

Results are below... note that these pics seem to have a hotspot near the center. I believe this was due to a smudge on the back of the lens. I didn't notice the hotspot until I downloaded, and went searching for the cause. Nice greasy smudge, near dead center on the rear glass. Can anyone confirm this can cause a hotspot in long exposures?

No idea how I managed that one... I am so careful. Alas. Anyway, I'll retest, sans-smudge, soon. The trees look excessively fuzzy because it was windy, and these were 6-15 second exposures.

I dunno but the pics are beautiful! especially the first one

[misterx.livejournal.com]

The first is my fav too.

[nayad.livejournal.com]

Yeah--the first one is magical! Awesome. :)

[summerwind783.livejournal.com]

I really like 1, 3, and 5. Though I have to say 1 is definitely my favorite of the pics.

[misterx.livejournal.com]

#1 is my fav too. :)

[ruethee.livejournal.com]

I love the first one. It would make a really cool tattoo, too.

[misterx.livejournal.com]

especially if your skin was lavender.

[ruethee.livejournal.com]

That's what lavender ink is for. And magenta.

[misterx.livejournal.com]

true. :)

[sinboy.livejournal.com]

The first picture is incredible. it looks like the whole landcape is on fire. Can you get that effect reliably?

[misterx.livejournal.com]

pretty much, yep.

[sinboy.livejournal.com]

To quote Lord Buckley, then, "If it's a good lick, use it." What other sort of scenery can you get this with? Does it work with people in the shot?

[misterx.livejournal.com]

These are 10-15 second exposures, most of them, so they'd have to hold very still. :) The people pictures I've taken before have a very haunting quality about them.

I took a few the other day, not sure how they turned out. I wasn't using a tripod, and I can't figure out what the heck to focus on, so I'm going to guess they're pretty bad. :)

[misterx.livejournal.com]

Yeah, focusing is a trick. Here's what I do. Looking through the viewfinder normally, click the shutter halfway to activate autofocus. That should make the little light flash in the viewfinder. Once you can see where the light is, you can sort of superimpose it on the scene by leaving both eyes open. Once you get the hang of it, it works pretty well.

Usually what I do is focus that way, then either (1) keeping it held down half way, recompose the shot and then full click (best for handheld), or (2) autofocus, then set focus to manual and make small framing adjustments via trial & error using lcd (best when using tripod). I used method 2 on these shots.

[misterx.livejournal.com]

Doh. I totally spaced on trying live-view with it. duh. I need to do that.

[nonspecific.livejournal.com]

Live-view? Are you talking about the LCD screen? Cause mine no can haz.

[misterx.livejournal.com]

Yeah. On my G5, it did an auto-compensation thing on the screen that let me see enough to frame the image. I wonder if that will work on the Mark II.

But, for what it's worth, I've been framing shots the way I describe using both the 20d and 5d, and it works.

Are you using the same lens that you used before? some lenses are prone to creating hot spots in IR

[misterx.livejournal.com]

No, this is a new lens. But I'm REAAALLLY hoping it was the smudge.

[alby.livejournal.com]

Take a look at what the folks at the IR community say about hotspots for IR:

http://irphotocom.proboards.com/index.cgi?board=gear&action=display&thread=66

I have seen hotposts using a lens in my IR-converted camera but not when I use the same lens in a regular camera.

[misterx.livejournal.com]

Thanks for this. The example certainly looks like the hotspot I was seeing. :( This will be most disappointing if it's a function of the lens, I had hoped this lens would be superior to the f 1.8 I had used previously.

[alby.livejournal.com]

They react totally differently to how they react to visible light. You can always use a cheapo lens and may turn better for IR

[misterx.livejournal.com]

Thanks! That is my *sassy librarian* look. LMAO

[misterx.livejournal.com]

No fair using my weakness against me.

[ianlyzu.livejournal.com]

what would that look like if you had a person as your subject instead of trees?

hintity hint hint

[alby.livejournal.com]

With the color pictures, have you played with swaping the green/red channels or changing the point for the neutral tone? I can share with you my recipes if you want.

That first one is a dream I wish I had.
