Thanks Nora, my camera was part of my daughter’s science fair experiment for three months, which rather limited pictures this year (though if anyone wants to see thousands of pictures of the same lawn, my daughter could help you out there).

I've just been reminding myself how lightzone works, a Zonemapper filter + a blue filter for example.

Technically not a Black and White photo, more a photo of Black and White

When it comes to digital, this is (IMO) the only place that shooting in RAW makes a difference. A RAW version of a file preserves the full colour depth the camera is capable of, then when you convert it down to another format (such as jpg) you can control how much weight to give to different gradations of colour (and by extension, luminosity).

Capture: Two Tone, in reply to Ross Mason,
You can’t take out “half the red” digitally
In photoshop and related programs, you apply curves to particular channels (possibly also with some form of fancy selection in place to limit what you effect).
On a semi related note, I discovered the other day that a personal favourite of mine in photo editing software (LightZone) has been made open source (Win/Mac/Linux). I think the ZoneMapper beats Photoshop's curves and it has a bunch of options for black and white conversion

Hard News: Thursday Music: Doing the Business, in reply to Hebe,
inspiring my 15-year-olds to keep working on their projects
As a parent of a high-performing 15 year old daughter, I am feeling very much the same.

We have never had a satellite dish of any sort, and are within very clear line of sight of the main tower in the area. With a new powered antenna we get occasional dropouts, and the signal is petty marginal in the rain. But to be honest, we are largely a post-broadcast TV household, so it doesn't matter much.

I will admit, putting together data sets to run my own analyses of questions in the media is basically a recreational activity of mine. I'll have to keep in mind this is a option for sharing what I've come up with, though most of the data I use would take quite a bit of adjustment to get into a form that would suit this wiki.
And, on the off chance, I will ask if anyone knows where to find a time series that the is either the total value of Australian housing stock, or anything it can be derived from (for instance average dwelling price divided by average household income I could work back from). Australia is completely impervious to my google-fu (I can find things like the 8 cities series, but I really need a countrywide measure, ideally for the last two and half decades, for a comparison I have been doing).

Herald digipoll have tended to report better numbers for national than Roy Morgan. This reading for National more or less matches Roy Morgan's value of 41% for National from a couple of weeks back during the Labour leadership contest.
