Stefan, what a stunning series of photos from Slovakia. I particularly like the photos with water and aqueous plants in them. I'd love to know how you achieved the underwater pictures. Well done!

I wound up down at Portland Head Light yesterday, and took The Mandatory Shot of the Lighthouse before realizing that shooting the spot where I was making TMSOTL could be interesting in and of itself.
Shot low with the 10-20, this chunk of dirt probably has had more people standing on it than anywhere else in the state (if not the country). Theres a reason 95% of the Portland Head Light shots look identical, and this spot is it.

Pretty as a Picture Postcard Sagitta Sir. Perhaps the landscape photo will stand out if you crop out some of the excessive foreground dirt.
I have attached a re-done photo & hope you will not mind. I have also made the dirt slightly earthier in color. Of course PP is difficult with a small file size.
Also the rooftops on the houses near the Lighthouse stand out a little bit more in a 3-D effect.

Underwater

I have just bought this underwater bag:

DiCAPac WP-S10 Waterproof Case WP-S10 B&H Photo Video

It perfectly fits Pentax K-3 body and Sigma 10-20/4-5.6 EX lens.
Dicapac lens is of high optical quality made from polycarbonate, it is not glass, so polarizer filter can not to be used, it destroys image with colour artefacts.

Pentax should be switched on and everything must have be set, before inserting onto bag, because controll is possible, but not as easy, as with dedicated underwater housing (very expensive ones).

Setting is as follows:

ISO 640
f8 aperture
Aperture priority
Manual focus, set close to infinity, everything will be sharp, because of wide DOF

It is not easy to swimming in stream of abandoned danube menaders, water is not still, I was everytime moved out of place,
I would like to take picture. The camera must be held with both hands, I had no oxygen bottles, so I could take just few pictures and breathe, etc.

I was also wearing neoprene, because water was cold.

But finally, I have made it and was happy with perfect results. This year I plan another trip to these places, to take picture of water lillies.

That clod of dirt was actually the subject of the photo. The lighthouse was background - I shot it because its the place where *everyone* takes this shot. If you Google Portland Head Light, almost every photo will be of about 3 separate variants where the only real difference is the time of day or weather when the shot was taken.

(It doesn't hurt that the 'prime' focal length to catch the light from there is around 50mm... I shot this with the Pentax M-50 f/1.4, stopped down of course)
