There are a few good guides for studio flash which are worth reading:

especially part 3 & 4:

Additionally, I'm sure The Flash Centre have some stuff buried on their site - and you can call them for advice (especially if you're going to buy from them):

HTH!

Best to start with one light and use reflectors... when you've sussed that out then progress to more lights

Matt

Zoweee! That's close
Matt

In Silkypix use "Open Folder" (not Open File) and you'll see all the thumbnails

There is a Camera RAW plugin for Win XP, but it won't cover the K10D yet.

Just worked out 17mm in an equisolid angle projection fisheye and I get 158 degree AoV on film and 97 degree on digital.
So the 1.5x seems to stay true...

But fisheyes can be funny little things
Looking at the chart on Bob Atkin's site, stereographic and orthogonal fisheye lenses won't follow the 1.5x, but equidistance and equisolid angle will

Matt

Itsme,
For rectilinear lenses (ie, not fisheye) then you do multiply by about 1.5x.
So the 18-55 behaves much like a 28-80mm (ish) on a film camera.

With fisheye lenses the result is a bit different (Yes, I said I'd look up the maths and work it out... it's definitely not mental arithmetic )

EDIT: Just checked on Wikipedia and there are several types of fisheye all with their own equations... not sure what the Pentax 17-28mm fisheye is ( http://en.wikipedia.org/wiki/Fisheye_lens )

EDIT: Equations are here: http://www.bobatkins.com/photography/technical/field_of_view.html

David,
There are two phases to a virus:
1. Getting itself onto the media
2. Installing itself into the computer and becoming "alive"

If I plugged your card into my machine it would warn me, but wouldn't allow the virus to get to stage 2 (I use Eset's NOD32 on all our PCs which I highly recommend). If you don't have adequate AV protection then there's a chance that the virus could get onto your machine.

However, formatting the card in the camera will erase everything - virus included

But, it's always a good idea to make sure you have up-to-date AV files.
(That said I once installed NOD32 onto a laptop that had nearly 30 active viruses because the owner had had no AV protection at all. NOD32 wiped them all out with absolutely no fuss at all and the job was done in less that 30 min )

Matt

Interesting - if you really do have a physical failure on the card then nothing will recover. Maybe that's why there are big differences between the two.

I had a friend who had a Sandisk that died with a hardware failure - I tried absolutely everything. In the end they replaced it under warranty, but he lost the images

There were some other recovery packages, but if it's that badly gone, I don't hold out much hope.
Matt

Nope, you haven't lost everything

Try Zero Assumption Recovery - it's free

Tutorial:
http://www.z-a-recovery.com/demo-ir.htm

(Actually you download the evaluation of ZAR 8 and the image recovery functions are free)

Not sure if it does PEF though...
There are others out there, and they have a varying rate of success. You have to keep trying until you get what you need

Matt

Lilly,
It's not absolutely essential... however, there are a few caveats to bear in mind:

* Adobe can only edit DNG, not the K10D PEF format. So, if you go for RAW, set it to DNG (which are larger files, BTW)

* Pentax's RAW convertor isn't bad - it's the Silkypix RAW engine. But it's a cut down version.

* You can download the Silkypix Free version from www.isl.co.jp - that should at least give similar functions to the Pentax RAW convertor but a nicer GUI. You could also try the 30 day full version of Silkypix as well.

I (think I) installed the Pentax software... but can't remember using it
