Yeah, sign me up.

Won't be able to join in everyday, as I'm on vacation in June for 2 weeks, but will do as often as I can.

I'll be using the Lensbaby pinhole option.

Here's my World Pinhole Day attempt.

Here I come. I'll probably use the Lensbaby zone plate/pinhole optic, but I've also got a ready-made and a homemade. I'll probably use all of them.

I have been meaning to make a pinhole lens with a body cap and I saw this!
The lenoxlazer website has a different cap for the canon rebel then the 10-30D... why is that? I have a 5D II....

Yeah, I know, I purchased it anyway and it works well. The cap is a bit tight. I think it has a focal length of about 50mm and about f/180. Any EOS body cap will work on your 5DII.

What do you think, is it worth it or should I just make one?

I'll join this side challenge but I won't be posting every day what with the DPL and all. I like using my bodycap/pinhole out in the field, I like to tell people I'm practising taking photos without a lens before I start seriously shooting images. They just smile politely and walk away.

I'll be using my self made pinhole from a body cap. Also, all my shots will be in B&W.

For those who may be new to this.

The hole you make in your body cap is not the hole you use to capture the image. What you need is a piece of aluminum from a pie pan or where ever you can get some thick aluminum, not foil. You need to make a very small hole in this aluminum with a needle and tape/glue it to the body cap by making sure it's centred properly so your images are centred on the sensor. Make the hole very small and try it out. If you're not getting enough light in there then enlarge your hole but very minutely. Try to keep the hole as round as possible as this makes for an even spread of the light onto your sensor. You really don't need a large hole to get the sensor to pick up light. Remember, you have no aperture to play with and the only way to control the light is to control the shutter speed.

Have fun.

I haven't had a chance to play with the Lensbaby pinhole optic yet so sign me up for this.

Totally different flavor. It took several attempts get my self made usable.

This was one of my first images with the DIY bodycap. The "hemi"vignette got old quickly



So, I widened the whole, the vignette below was added in post. The nice thing about 5DII is the H2 ISO setting (25600), crazy noise/texture.



First adventure with pre-fab body cap, almost too sharp.

I'd like to sign up, and learn about this. I'm not sure which kind yet, I need to look into the various possibilities.

I'm in, though I'm out of town the second and last weeks of June.

My cameras: oatmeal box, super wide angle cigar box. And if I get around to it, body cap on the E-520 and maybe my 35mm Populist.

How to create a pinhole camera from an oatmeal box:
//users.rcn.com/stewoody/
Example:

How to create a 35mm pinhole camera:
//idea.uwosh.edu/nick/pinholephoto.htm
Example:

The first one is easy to build, but requires chemicals and a darkroom. Don't let that put you off though; the chemicals are easy to get and easy to work with, and a dark bathroom will work fine.

The second one is a little harder to build, but since you're using 35mm film, a trip to the drugstore is all that's needed to get your images.

I'll follow along to see what you all come up with. Have fun!

Don't know how often I will contribute, but I'm in... just ordered some 0.3mm carbide drill bits so I can make a clean hole. Got some very thin shim stock laying around so it looks like I'm set to go. I'll use the Canon body cap and mount my pinhole in that.

Yay! Hi there :)

I'm certain my around the yard/house drill won't utilize something that small. What do you use?
05/22/2010 01:40:25 PM · #20
Brian, thanks for the links. I'll add them to the OP.
05/22/2010 02:58:13 PM · #21
Forgive my guys, but I have never participated in a SCT before. How does it work? :)

SCT? Side challenge t......

There aren't really any rules unless the OP has something specific in mind he wants us to stick to. In this case the topic is pinhole imagery so the only rule would be to use a pinhole camera as in a modified body cap or a box such as an oatmeal box. Remove oatmeal! ;)

As for images the OP has said it wasn't necessary to post one every day so you don't have to unless you want to. You can use any rules to edit your shot if need be. Sticking to how we process our images in challenges is the norm unless, again, the OP has other things in mind like textures or compositing.

These side challenges are meant to be stress free and fun since we're participating in something we all have a particular interest in. No deadlines, no challenge descriptions to deal with, just plain creativity and imagination. ;D

Oh I forgot one thing, commenting. Try to comment on the images as this helps the photographer hone his skills and it lets you discover new techniques to use in your images. It's a learning process for all.

I really like how all the film was used here. It's rare I see this done this way. Have you tried a larger film format? I want to try this out someday, after I've moved and settled in though, not during this side challenge.

Thanks Jac. At the link I posted, there are also directions for building a medium format camera (120 film -- think Holga), but I haven't gotten around to that yet. So many projects, so little time...

Ok, so I made a bodycap pinhole lens this afternoon!
Here is a shot

20s exposure, 100 iso

I drilled like a 1/4 inch hole in the cap and then punched a hole in a piece of steel foil tape with a sewing pin and stuck it over the hole.
