Great observation to spot that shot, Lilly

ROFL

Ok, 'twas just a thought.

Does the teleconverter have all the relevant contacts?

Google Dirks' surname. Interesting first hit! http://trotteyn.com/

No worries. When in doubt, RTFM

None of my pictures have labels in red text in Pentax Photo Browser!

Edit:- found this in the help file (referring to the Options dialog box)

Indicate Changes in Image Data During Frame Advance
Sets whether to indicate changes in image data in red from one file to the next during frame advance in the Main image view window.

Yes Changes in image data from one file to the next are indicated in red.
No Changes in image data from one file to the next are not indicated in red.

Edit 2:-

Got it! If you use the arrow keys to move through the thumbnails you see the data in red (because it changed) If you just mouse click from one to another it stays black.

Very Good

In #3 I'd like to see a bit more of the brides face, enough to see her expression.

Welcome to wonderful world of (D)Slr photography!

Remember that shooting digital pictures costs next to nothing, so don't be afraid to experiment!

I did stumble across a website that carried a good basic tutorial, but I can't find it now! I'll post it later if I can find it. In the meantime, have a look at our "sister site" www.ephotozine.com they have a lot of tutorials there, and galleries of photos to inspire you.

All the best!
