Calidea dregii - take 2


I wrote some stuff about taking macro pictures and this nymph of the Rainbow Shield bug (Calidea dregii) on Wednesday. If you have forgotten and want to re-read, just click on "previous" above.


This chappie or chapster is running along on a 1mm electrified steel wire. Type of wire to keep out bloodthirsty animals, from the camp where we stayed in the Kruger Park. I touched the wire accidently just after taking this shot (I think my finger touched the lens casing that touched the wire). All I know, is that I screamed like a girl, meeting up with a rain spider in the bedroom. I mean scream, not shout. My finger was sore for a day afterwards.


More on the photographic front. You may remember my issues with macro photography that I recorded on Wednesday. Anyhow, this time around I used my 50mm f1.4 lens on an extension tube. I narrowed the opening to f9.0, waited for the bug to stop a second and shot on autofocus. The speed of 1/40th is relative slow, but the lens is not always hunting for focus, like the macro lens. So actually, I have a better chance of taking a good shot with the 50mm/extension combination. Because this combination doesn't zoom in and out all the time in the process of finding focus, it proves much faster and steadier in use. One can also increase magnification by holding the lens closer to the subject. And unthinkingly touch the wire ...


A great weekend to you all.

Another good shot of this colourful little beast, Louis. You have a good weekend too.
Louis: Thank you twice, Frank.

It is a stunning gem, Louis, and I loved your instructional anecdote.

Once, while on a multi-day bushwalk, I stepped over what I was told was an inactive electric fence...when the wire touched my crutch I knew it was not a dead fence!
Louis: Thank you Ray. That experience of yours is shocking in more than one way smile
you did good with this beautiful nymph of the Rainbow Shield bug Louis... thank you fists for putting up with the pain... and the way that you found to capture this shot without getting another shock....petersmile
Louis: Thanks peter. They say, one is never too old to learn.
Magnifique Louis!
Louis: Merci beaucoup, m'dieu Richard
The battle scars we endure for our photography, plus their stories, could surely fill a good book, Louis. Congratulations on figuring this macro out.
Louis: Thank you Ginnie. Oh yes, there are many of those stories.

Stunning stuff Louis, just don't stun yourself on that wire!
Louis: Heh, heh - that was a shocking experience, Chris.

Oh, you followed him on his way to --- a great macro image!
Louis: Dankjewel, Philine. Een heleboel van de beestjes was daar op de hekwerk.

Hello Louis, still a very good shot wonderful pictures!
Louis: Thank you Aged, your comment is appreciated.
I had not realized until today that it was a shield bug. I use manual focus for that situation. It is maddening when you are trying to get a shot and auto focus starts hunting.
Louis: I tried manual focus, Mary. One issue is that the nymph keeps moving and the other is that something in me is not suited for manual focus in this situation. I focus, then am not sure and re-focus - guess what, the bug is gone. It is much like auto hunting, but I am doing it myself. So I sometimes use the macro lens for low light landscapes, because it is a fast lens.
It's on the move Louis. I loved your description of touching the fence. Of course, an electric shock is dependent on a complete circuit or no electrons can flow. You completed the circuit nicely, but this poor thing is simply having to cope with being at the same potential as the wire so cannot enjoy the thrill of atoms passing on their electrons throughout its body.
Louis: You are scientifically inclined, gutteridge smile It must happen that these bugs sometimes complete the circuit, in some way. Sometimes you can hear the electricity snapping, but there is nothing to see.
This is a brilliant shot Louis, very well done.
Louis: Thanks a lot Brian. I suffered for it smile
I have a set of extension tubes sitting on a shelf and a 50mm Lens....I really should try something like this. Cracking picture Louis
Louis: Thanks a lot Bill. I think I should use the equipment more. I like it when I finally get the macro's right.

J'aime beaucoup les couleurs de cet insecte.
Louis: Je vous remercie, Martine. Ils sont très colorées, en effet.

I did read your write up and that is a lot of technical stuff. Always fascinated by 'what others do'.. I had to admit that after 2,5 year I finally 'get the gist' with my camera (there is NO automatic button on mine) It is fun to explore.
This picture is another likey to me. I love the small world (Am I fully awake and this is NOT a selected colouring, is it??
Have a wonderful weekend.
Louis: Sometimes, I think we share too little of these experiences. After all it is a photography blog site. My camera has an auto function, but I very seldom use it. Thanks for the likey, Astrid.

Fantastic colours against that dark background. Looks really sharp
Louis: Thank you elleplate. I had to jack up my macro skills for this. I am shooting macro's way too seldom.
