[Note Guidelines] Photographer's Note

The study of physics put forward the idea of open and closed systems. An open system freely allowed the flow of energy in and out of that system, while a closed system would not. Ecologists argue that closed systems do not exist. All systems (although they may be self contained to a degree) interact with surrounding systems. This does not matter whether you are
discussing our Solar system or your nearest fishing hole.

For many years conservationists treated our national parks and reserves as closed systems. They selected a good piece of land, uprooted anybody living there, threw up fences, stocked it with game and tourists and allowing no outside interactions. Latter day ecologists recognise that this is not a sustainable practice.
Without taking into consideration the needs of surrounding areas your ‘closed system’ will deteriorate. Today the vast majority of formal conservation areas are recognised as open systems to a degree (i.e. the game is still fenced in), a policy that works most of the time (poaching remains problematic) and surrounding communities are deriving benefits.

One would have thought that conservationists would have learnt from ecologists a lot sooner. ;)

This was the last "wildlife" scene Paul experienced before boarding the plane on his way home. It was a lovely sight for me and I got the chance to use Paul's Sigma 10-22mm wide angle lens. Now to visit the bank manager... :)

Velvia colours today, Gerhard :-) Wide angle lens helped you to make this amazing pictures. Lovely colours and composition with blues, greens and rhinos. Interesting note and great souvenir from meeting with friend. Great post!

i like your note on closed and open systems..
thermodynamically i suppose although open systems exist..overall they must be closed and gradually revert to no energy difference

i like the open wildlife reserve concept..it allows migration and predation on a correct scale....i remember the story of the lions who wouldnt attack the over abundance of water buffalo to order and ate the bongo...so reducing drastically its numbers...another closed system failure..

ps i like the shot..:) its has the atmosphere of nature and africa

A stunning shot Gerhard, perfectly balanced. The sky is amazing (I've forgotton what blue skies look like!!).
A superb composition and note.
Thanks for posting.

Hi Gerhard,
Very beautiful view, great composition,
perfect exposure, amazing colours.

Hi Gerhardt,
I love good landscapes, and this one is VERY good! This really conveys a sense of how vast the Savannah is. Beautiful colors, the exposure looks to be right on the money. The clarity is superb. It is always good to see air that is not heavily polluted. Just a great overall scene to soak in.

It's a wonderful landscape that gives a very good feel for this country where you live Gerhard. I love the popcorn clouds, blue sky and lush green color..The brown line of dry grass on the horizon, illustrates the attempt at containment, or the "closed" system you speak of. Very well done.
Thank You!

Hi Gerhard,
I hope you had a good start into the New Year.
I like your shot very much - the sky is wonderful - and there are so many animals, amazing. Thank you very much, bye

Lovely landscape, Gerhard. Beautifull sky and clouds. Did you use a polarising filter, or is it just the wide angle lens? Great shot!

This is a great landscape shot with a perfect exposure, the animals look peaceful in this beautiful land. I'm guessing those are white rhinos knowing that they're grazers, and seeing that there's not much browse that black rhinos feed from. :)

Lovely shot Gerhard!
It has quite idyllic look. Blue sky, green grass, wide space. If not the rhinos I would thought it was taken somewhere in Europe rather than Africa. Somewho it doesn't suit my image of this land.
Anyway, it's beautiful.
PS. I like to read your notes a lot!

Personally this is very good for me as whenI think back on SA, I think of lots of sky and this has it! It's also sad for me because this was my last day there and it brings memories of going to the airport. Thanks for posting and making me stop and think.

It is a beautiful landscape that could be many places, but the wildlife on the land definitely makes it only Africa. Well shot Gerghard, and thank you for showing us this area of the world where many of us would love to go, but know that we won't. THANK YOU...

Hi Gerhard,
It's a beautiful landscape picture with very nice colours.
Well composed , well exposed and good POV.
Your note is great.
Great work, my friend.

Hello Gerhard
I really like this shot - the vibrant colours of the sky and landscape first attracted my attention - but it's one of those shots you can look at for a while and find new details all the time - but without it looking cluttered. It's a lovely simple composition and the rhinos and antelope are great.
Thanks for sharing

Gerhard, a beautiful and broad perspective. What a privilege to have such a view.

Excellent composition, lovely shades of blue.

I like saturation.

Already visited the bank manager? :)

The old hometown looks the same
As I stepped down from the train,
and there to meet me, was . . .
Many fond memories of this one, Gerhard. Hope the prosperity bores you this year.
Found a lovely new birding site - told you on the phone, I think. Also Rondebult and Austin Roberts in PTA, when you are around here again
Beutifull rendition with this lens, well done

Not talented only in animals but also in landscape!

Sharp and well exposed, I love the the depht and the immensity we can feel looking at it(wide angle view). Composition is well balanced and I like the light fall off on the edge of this picture (result of the cosine law of course) that darken the sky in the upper part and bring back attention on the horizon.
Excellent work and TFS.

Hi Gerhard
The scenery is already beautiful without the rhinos but they are definitely a bonus. I like the huge amount of sky with the fluffy clouds. Pretty colours.
Regards Toni
