For landscapes, don’t you need 1/32 for the field depth?
Not necessarily so. A smaller aperture will give you more DOF, but if you focus at the hyperfocal distance, everything from that point to infinity will be in focus. On older lenses, this used to be marked with a little infinity symbol on the focus-ring - on newer ones, it is not always marked.
For my 50mm lens, set to f/16, the hyperfocal distance is about 21 feet. If I focus at 21 feet, pretty much everything from 11 feet (about half of HFD) to infinity is sharp. And on my old 28mm lens at f/16, I used to get hyperfocus from 3 feet to infinity.
Not photographic advice :-)

True. This is why compact digital cameras (with tiny lens) never have DOF issues. :)

What would a completely transparent real estate market look like? Could it ever be achieved, and if so, how?
I mean immediate and reliable data on all completed house sales, all houses for sale, and local population housing wants and financial abilities, all available to everyone for no cost.
I think such freedom from data delays, broker data hiding, and the manipulation of statistics by the NAR would the healthiest thing for the market. But since there are only weak requirements to report house sales (in San Mateo County, for example, only the easily-manipulated transfer tax is reported) and no requirements at all to report houses for sale or accept the advertised price, I don't know exactly where to get the data.
Maybe some system like gasbuddy.com is the answer, where anyone can report prices and sales in their area. But gas prices are very easily verified, just by buying some gas, while house sale data is usually delayed and/or hidden.
