ITs pretty decent, Try for the classic 3, Water, Leaves, and Clouds.
...Oh wait is has a copyright watermark, NM its super gay.

Doesn't seem to be focused properly.
Very boring subject. I think even the normal color picture would be better.

Oh, and shitsize watermark ruins it.
>> Anonymous
OP here. I put watermark on it so people don't steal it.

AHEM.

anyways, it's my best result so far. It's hard to get subjects in focus with limited light mainly because infrared needs a lot of light.

Also, the infrared looks much better than normal colors IMO.

Like anyone would want to steal shit like that.
And just focus manually. Just don't think an IR filter will make bad pictures better.

how does I clone stamp?

anyways, I was looking for critiquing on the actual picture, not the water mark.
>> Anonymous
oh and also, the picture is in focus, it's just not very sharp.

I was using manual focus + tripod.

There's no excuse for lack of sharpness in that situation.

set focus
place filter on camera


tip: if it isn't a good photo without the filter, it won't be much even with it

A water where you have it will do as much good as an anus on your elbow. Five seconds in shop and that mark is gone. You have place it over detail, and even then anyone who knows what they are doing can peel it off with work. Just don't give them sizes worth using and hope for the best. Also /p/ hates watermarks, .png, and HDR.

First, I might be wrong about this, but I'm about 99% sure IR light focuses differently than normal light. So focusing bare wouldn't work.

Second, there's a perfectly good excuse for it not being sharp. It's a four second exposure and there's such a thing as wind. Plus, it's probably the kit lens.

Third, there are photographs IR will make or break, just like with any technique. Adams's "Snake River" photograph would've been shit if he had thrown everything out of focus but the mountaintop, but Kim Kirkpatrick's work would be shit if he put everything in focus.

IR focuses differently than normal light.
some professional lenses will have an indication mark on the lens, but many dont. Example of one that does is my macro lens.

Nikon's extra low dispersion glass, supposed to help with chromatic abberation.

IR is a different frequency than the visible light. lenses are optimised to be corrected for 2 frequencies in the visible light, Apochromatic lenses are corrected for 3 frequencies in the visible spectrum. other frequencies do not focus in the same plane, so theyre off, causing chromatical aberration

on IR you need to focus a bit further than where the focus plane in the visible spectrum would be. so well, for infinity focus, you need to stop down and use DOF to get infinity into focus.

OP here. Would it be better for me to use a high or low aperture?

Low aperture might fix the focusing problem, but then I risk it being not in focus because the exposure time will be even longer, etc.

/p/ have any tips for shooting infrared with digital slr?
>> Teus !QbSstcPD6U

use a tripod anyway when shooting IR. use SMALL apertures, F8-f11 are optimal

Agreed, I like the image. Infrared is not exactly an easy thing to do on a DSLR.
>> Anonymous
>>96256
I thought it was easier than P&S's, The only disadvantage is no AF and no Live View, but since you have to shoot static subjects its not really a problem.

IF you are going to be shooting anything moving then you get a modded DSLR, and then theres nothing to it.

Actually, if your camera's IR filter is shitty enough, you can even get live view on a P&S with an IR (well, "everything but IR") filter. It worked on my old PowerShot G1. Looked really wacky.

this was taken with my Fuji F30 p&s with a Hoya R72 filter.
comes out far better than my D70

Don't use the craptacular 18-55
and use the 50mm f1.8
or the best lens I have found has actually been a Sigma 15mm f2.8 fisheye

Also the lighting is far superior in the Fuji's pic than the Originally posted one. AND any movement of the branches will show up blurry as shit on the D70 pic (where the focus of the fuji is 90% on immovable (via wind) objects. (and a much quicker shutter speed)

Also beware of diffraction, never stop down more than f16 as you will "Unsharpen" your images. Stick with F8-F11 on most lenses.

i dont own the 18-55, as it never came with the D70, the 18-70mm is the one you should speak of, and thats a great lens.
I also own the 50mm f/1.4, but the FOV is too narrow on DSLR for any practical landscape shots.
>> Threadender
Digital IR pictures will never be as sharp as VIS ones, simply because the light reaches further into the sensor. The produced photoelectrons then randomly walk to any of the neighbouring pixels.
