From the Botswana file,  another pied kingfisher shot and another example of the selective focus/ blurred background look which I think works really well, particularly with bird shots.   With the bird pretty much in profile and the branch on the same plane of focus,  the wide aperture and resulting narrow depth of field are still enough to get what's important in focus.

Cropping alternatives.

     This image has been cropped to give a tighter composition than the full frame and of course there are numerous choices that can be made in this regard.    Check out the current banner image and you'll see that it's a different cropping variation taken from the same frame.   Some folks get rather precious about cropping "I never crop images", "I only ever crop in the viewfinder" etc.   Or that classic ultra pretentious piece of twaddle,  "I don't crop,  I preserve the integrity of the frame",  yeah right!   If you're photographing a building, a parked car,  a sculpture,  well and good,  you can use your bi-ped zoom function to fill the frame and avoid the imagined ethical dilemma of cropping.    (Technical note:   bi-ped zoom function:  the utilization of one's feet to get physically closer to the subject)  

      In nature,  sometimes cropping the image to get the desired result is required.   In this case,  the subject was happy to perch momentarily on the branch at a safe distance from me but sure wasn't going to sit there whilst I tried to get closer,  even if that had been possible.     KD. 

     Not a lot to say about this shot really....a sunset over the Okavango Delta, Botswana.   If you look closely you can just see an egret in the shadows.

Reloading mainsite.

     I'm in the process of reloading some files to my mainsite,  could take a few hours at the rate it's going.  If you visit the site and find some difficulty navigating it,  or you find some broken links etc,  please be patient.   This site maintenance should be complete within 24 hours.     Thanks KD. 

Update.

      My mainsite is now back to normal and the homepage image updated,  thanks for your patience.  KD. 

   Photographed in the Okavango Delta, Botswana,  this banded mongoose was one of a fairly large colony which we observed just before sunset.   They seem to be active and social animals and whilst we watched them,  they spent much of their time foraging through leaf litter looking for insects and grubs.

     Sunset over the Okavango Delta,  Botswana,  and a flock of open billed storks fly home for the evening.   This shot was taken hand held from a boat and processed in Photoshop CS3.   Given the detail in the image,  it's best viewed large and so I've prepared the image in several sizes and made them available as "wallpapers" with, where practical,  image dimensions to suit most popular computer monitor sizes.    For those who would like to use these as screensaver images,  they are available as a free download at my mainsite. 

      On the subject of my mainsite,  I've reorganised it a bit as well,  simplifying the homepage and including a link to a new "Publications and downloads" page where you'll find the wallpapers.   If that's too much messing around,  just click on the picture to open the link.   Of course it should go without saying,  but these images are the subject of copyright and are provided for non commercial use only and not for reproduction.    Cheers KD.

       Photographed in Botswana,  I had trouble trying to identify this bird but after scouring some of the bird groups on Flickr,  I was able to establish it as the lesser striped swallow.    Pity I wasn't a bit more organised,  I could, with a guide's assistance,  have identified the species whilst I was still in the field and noted it down!

    Not a weird Wednesday,  so much as a Wednesday whinge....

Internet frustrations. 

   (To tag,  or not to tag?  That is the question.)

     In recent months I've been alternatively using Technorati or Live Journal "tags" on my blog entries hoping,  that maybe,  they might help people searching the internet for information or articles on specific topics,  to locate relevant content here.   I'm now rethinking this practice and questioning its value.  

      I recall back in 1998 when I got my first computer,  turned it on,  and opened internet explorer for the first time.   In keeping with the advertising of the time,  I asked myself the question,  "where do I want to go?"   Being a complete newbie (I'm not sure if the word had been coined by then or not) I thought,  Microsoft,  there's got to be a site for Microsoft!   So I typed the word in and conducted my first ever internet search.  The search engine returned the "top 10" results of which the first 3 or 4 were for a computer shop situated on the other side of the planet (USA),  number 5 was I'vegotabigpenis.com  (I kid you not) and the remaining 5 sites which were similarly useless,  off topic or offensive.   

      With so many new pages being published on the net,  millions every day,  it's difficult for search engine designers to get it right and keep it relevant.   Having said that,  I believe that companies such as Google have made great efforts in the intervening years to achieve relevance in their searches,  it's an ongoing challenge.   Recently I decided to test some of the Technorati keywords that I've been using to see if firstly,  the results were relevant,  and secondly,  whether or not any of my blog entries were shown.    To cut a long story short,  they failed miserably on both counts.   The fact that my own blog entries aren't seen I can understand,  it's easy to get lost among all those millions of pages.  But on the issue of relevance,  it appears that for Technorati at least,  it's still 1998.  

      For example when clicking on my tag for "Serengeti",  I find out that there's a US based rap singer who calls himself "Serengeti",  there's a company calling itself "Serengeti Enterprises" or similar, which appears to have nothing to do with the actual Serengeti,  oh, and Fred Jones hit 2-0 off Bob Smith in the 9th innings playing for the Houston Daffodils if that means anything to anyone!  (I might have misread that one as it was of absolutely no interest to me)    The point is,  I had to scroll down to result number 14 or 15 to find out about the day rates for a resort that operates on the edge of the Serengeti National Park and that was the first tag result that was even remotely relevant to the search.   For those of you visiting from another planet (or Fred Jones fans) the Serengeti is a region in Tanzania in Africa teeming with extraordinary wildlife and is considered one of the world's great natural wonders.   Worthy of top billing on an internet/blog search I'd have thought.

      Another example,  click on "Malachite Kingfisher" and you'll find out that there's a swimsuit company called Kingfisher and they're taking orders for their 2010 swimsuit model calendar.   Now don't get me wrong,  I love women in bikinis as much as the next guy,  but if you're looking for something specific about Malachite Kingfishers,  forget it.

      The upshot of all this is that I'm now rethinking the practice of including tags in my blog entries.  Am I simply making work for myself by continuing to use them?  Is it a pointless exercise?    If anyone has any thoughts on how to make such tags useful, I'd be pleased to hear from you.  KD     

      Another early morning lion shot from my Botswana adventure.   As was the case with a previously posted image,  this one was accidentally underexposed but rescued in post processing.   Shutter speed used was 1/8000 second but correct exposure would have been about 1/1000 or 1/2000 second.  None the less I'm reasonably pleased with the end result.  The image has been up on my mainsite for a few days as the homepage image with linked explanation.   KD.

     From the Botswana series,  this pied kingfisher obligingly posed on a twig for me.  This species was frequently sighted both hovering over water and also perched as shown here.    Notice the blurred background,  a result of the background being well separated from the bird,  and the narrow depth of field, or selective focus,  given by the long lens used at wide aperture.    The stronger light and stationary subject here allows for a strictly realistic image when compared to the more "impressionistic" blurred effect that occurred with my hovering kingfisher shot posted on 7th October.

      An unscheduled blog entry,  just to make people aware of some of the rubbish that occasionally gets through the system.   I received a personal message from one of my network friends earlier today in response to a message supposedly sent by me.   The message appeared in her inbox,  with my email address as the source,  and contained in part the following piece of gibberish....

Hellooo!
long time yeah? no see? ...
anyway here you go
I got that for you... :p

      Anyone who's followed my blog for any length of time will be aware that I'm rather particular about spelling and grammar and would immediately be suspicious of the above paragraph.    In addition to that,  the "message" included a link to some other site.   By hovering the cursor over the link,  the web address can be seen and should immediately arouse suspicion.  

      It's not clear to me whether others in my network have received such "messages",  if you have then please treat them with the contempt they deserve and rest assured that I have not knowingly had anything to do with them.

      For what it's worth,  the only links that I recommend to anyone are those that I refer to in my blog entries.    KD.  

    Another shot from the Botswana series.   Shot in early morning light,  this majestic fellow also currently features as the homepage image on my main site.   Clicking on the banner image at top of the blog page will take you through to the other shot and linked explanation for those who are curious.   A reminder also that the custom list displayed beneath my profile image provides links to my other internet based activities,  Facebook,  Flickr etc,  with the most detailed explanations of my photos via the homepage image.   cheers  KD.
