I sometimes just hold my hand above the camera thus casting a shade onto the pinhole, but staying out of the angle of view.

Me too, and it made me laugh to think of what it did to me a couple months ago. I made a darkroom print using a homemade easel and there was a funny dark area in the upper corner of the print. I spent a lot of time trying to figure out what caused it ( filter ring, easel, homemade negative carrier, what could it be?... ) and finally looked at the negative and saw that it was in there the frame. Then at last I looked in my notebook and it said I was worried about flare and had made a second picture shading the lens with my hand!

When I purchased the Ilford Harman-Titan pinhole camera it came with an exposure calculator.
I colour copied this and laminated the thing, then cut the pieces out and put it together with a type of cutter pin.
Works great.
But, if possible and available, I like to start the metering with one of my Sekonics and then extrapolate.

lightmeter on smart phone for pinhole use


An other simple solution: I use the Pocket Light Meter app on my iPhone (also available for android). This app has a minimal ISO setting of 0.8 and maximum aperture of f/512 so very usefull for pinhole photography. It is very accurate too (I tested it). The app is free (with small add in top of screen) or $1.00 add free.
See: http://www.pocketlightmeter.com/

You can HOLD the screen - holding your last reading. You can also take a small snapshot to log the used settings - and add some notes. It can also sync with Dropbox to save the snapshots. Coming back home I check the snapshots to see what settings I used when & where: the file names show date & time stamp. Here is an example:


Here is a small test of this app: http://thephotobrigade.com/2012/06/pocket-light-meter-app-review-by-c-s-muncy/
