I don't recall us doing one of these, I could be wrong. Here is a description.

I'd go for this.

Me too, I just got a pinhole body cap from Lenox Laser.

Here are a couple of samples...

BTW, I don't think this is a realistic challenge topic. Entry numbers are already low. I would be shocked to see this get 20 entries. Folks would need more than the typical 7 days to enter, as most will need to make or purchase a pinhole.

Topaz now has a "Lens Effects" plugin that, among other things, has a pinhole emulation module. But I guess that wouldn't please anyone, right?

Come on, why even ask?! ;)

Nik Silver has a pinhole preset, obviously it's not the same. I have not seen the topaz version. I'm guessing that like Nik, it's about contrast, grain, and a vignette rather than the soft focus and deep depth of field.

Welllllll...

The plugin is very complex. One subset of it has the pinhole stuff, and that's primarily as you describe. Not much to talk about there. But there are other, much more interesting modules, and among those are modules for wildly varied soft focus effects and extreme DOF manipulation...

But don't get me wrong; none of this can touch the fun of actually USING a pinhole or lensbaby or holga, and seeing it happen on all its own :-)

Nevertheless, it's a way-serious-fun plugin that I am gonna enjoy messing around with:

Enjoyable images, but you have to admit they don't resemble pinhole images.

Oh, sure, those have nothing to do with pinhole, or pinhole emulation; they're just 3 of the very different looks I have coaxed so far out of the software modules. I haven't even TRIED the pinhole module yet :-)

Would be a fun topic (reminds me I'm behind again with my PAW), but like Ben said, I doubt it would get much participation.

Simple, take a thin piece of cardboard, us a pin put a hole in it, attach to front of lens. But you're right, this wouldn't be a big draw.

As I understand it, pinhole photography happens without a lens, limiting the challenge to those with dSLRs and a pinhole "attachment" of some sort.

One possible alternative would be to take a picture which includes a projected pinhole image, essentially taking a picture inside a camera obscura. But I think that's too complex for a one-week challenge ... maybe two weeks to enter would work.

Now that would be interesting.

The attachment is a bodycap, but you are right, the non-DSLR crowd would be left out if it was a strict pinhole challenge. How about anything but your naked lens? :) Put something over the front element or use a bodycap, etc.

I know these are not pretty, but I like them...

Here is an image made with slits in tin-foil.

Fresnel lens over a pinhole:

Thick plastic and pinhole:

' . substr('//images.dpchallenge.com/images_portfolio/50000-54999/54645/120/Copyrighted_Image_Reuse_Prohibited_925342.jpg', strrpos('//images.dpchallenge.com/images_portfolio/50000-54999/54645/120/Copyrighted_Image_Reuse_Prohibited_925342.jpg', '/') + 1) . '

I think this would end up inspiring similar ideas as some in the recent homemade filters thread.

I have never experimented with a pinhole, except maybe when I was a kid with an oatmeal box. Maybe someone should think about reviving one of the older threads into an ongoing thing for those that would like to shoot and show.

sweet. i have always wanted to do a voyeur photo.
