Fun with IR

[richardHaw]

going to be posting more IR from now

35mm f/2 Ai

notice the weird edges on the ghosts

at least this lens doesn't have a hotspot

IR is fun, almost by definition.

Lenses are much more prone to flare in IR as well.

The first image looks surreal, almost as though the people are green-screened in.

The IR frenzy caught up with you
Do post more!

Nice Richard.

The first one seems straight out of a scifi movie.

Yes, I noticed that too.

should I modify the focusing of my camera? is the focus shift the same across the board for all lenses?

it's probably missed focus
that focus shift thing is hard to get used to

it's the "Minions" movie

I want to make a collection of samples for my lenses in terms of IR in different apertures, shooting outside of my window. how would you guys go about doing this? So that people will have an idea of how a lens performs at various apertures.

Generalisations about IR performance is made complicated by the fact that not only the lens, but subject, light, filter, and the camera all have an influence of the outcome.

I see, so some digital bodies will give hotspots and some will not?

I am thinking of a general scenario like shooting a building outside of my window in the morning when the sun is facing my bedroom and taking notes on how it looks for each lens at these given apertures and exposure.

Some lenses gives an IR Hot spot,,, not camera specific

If I might butt in for a moment...

I posted a question in the camera forum but got no replies, but perhaps you can help me here.  I have a D3200 that I'd like to have converted, but am not sure which of various IR options might be the most useful.  What sort are you using here?

That's fine Matthew!
I am using the super blue IR! 
i believe that this is what many of us wanted instead of the deep monochrome IR
