No, no, no Dave...that way leads only to a McDonalds-style homogenity...
Instead pop down to your local Poly and sign up for some advanced white-water rafting classes....it appears you have the perfect conditions for it !!
Paul, meanwhile, can check out some books on cloud-seeding from the local library....
Addendum...Being new to my K10d I am playing catch-up for it's attributes, operation, and modifications....
I've owned a K200d for several years so I jumped at the opportunity to acquire the K10d for experimentation and "modifications".
It has been bought to provide a dedicated studio recorder of my weekly output. (I am a contemporary Metalsmith.) So I set about configuring it as a stay-in-place-almost-macro (often jewellery) capture device.
Firstly it had to be tethered...to my preferred o/s, Linux...

Next, as I will mostly use it with manual lenses..(Nikkor enlarger 50mm/f4...8-element Pentax M 50/1.4...m100/f4 Macro, tubes, bellows, etc) I needed a better focus option.
Having some redundant Pentax film SLRs (MG, MX with 2 screens, 2x Me-Supers) I thought to rob one of it's split-prism focus screen and modify it to fit the K10d.
The spare ME-super wound-up being the donor.
I measured the K10d screen with calipers (25x17mm) and made a paper template with a punched hole at it's centre. I laid the Me-Super screen on some printer paper then lined up the template using the punched centre-hole over the split prism.
Once everything was in place it was taped down with ordinary sellotape.
Note...unlike other tutorials this method only has tape on the portions that will be cut away ! and paper elsewhere.
Using a Jewellers Piercing saw the sandwich of tape, paper, and screen was cut around and the edges cleaned and smoothed.
Unfortunately my paper turned out to be some recycled sheets from the ink-jet printer and several smears of black ink were left on the otherwise pristine screen.....not to worry as I had several other back-up screens so why not push this one a little more..??.
With a tissue and a dollop of hand sanitiser(mostly alchohol
..) I gave it a gentle clean and rinsed with warm water, then gently dried with a Rocket Blower. All clean and new again !
Now installed and a most worthwhile modification ! I can put the original screen back at any time but the benefits of this new screen mean I won't.
Exposure is challenging as each lens and each aperture setting need a different compensation but I am slowly building a database...luckily the settings are consistent..
As I am shooting in a studio setting with constant light this is all much more do-able. Though a little time consuming to begin with...
Many thanks to all you K10d contributors whose knowledge and previous experiments have helped make this a workable project !!
