Dear all, thought I would post a few 7D bugs; i.e. bugs taken with the 7D! In this case mosquito larvae. These shots are being taken for a book on Australian mosquitoes.

All images shot with 7D, MPE65, MT24ex using a small glass tank with a blue cardboard background. In the past I have used cold light sources, but the MT24ex is much better. For these shots, water is passed through a 0.2micron filter to remove any particular matter (otherwise too much cloning required) before the larvae are added. It is also important to have extremely clean glass, again to avoid hours of removing spots.

Aedes nivalis (a snow-melt mosquito) this was a stack of four images, combined in PSCS5:



Aedes notoscriptus (common around homes in Australia):



Aedes rupestris (breeds in rock pools along freshwater creeks), this was just a lucky shot:



Aedes rupestris pupa:



Anopheles annulipes



Culex annulirostris (a major vector of mosquito-borne disease in Australia):



Culex australicus (this is covered with a commensal organism, Vorticella)



A 3rd instar Culex australicus (the others are fourth instars):



Closeup of the head of a Culex australicus:



Culex molestus (breeds in septic tanks):



Culex quinquefasciatus (this is the one that buzzes you at night while your trying to sleep):



Finally some shots of the amazing Toxorhynchites speciosus (this eats other mosquito larvae):







Kind regards
Stephen
 
Very cool - great work!.

Also love the Thread Title - Got me to look. ;)

Thanks Gord for you generous comments. I agree that it does take a lot of patience, but not much talent is required; modern SLRs with ETTL flash metering makes it very simple.

Kind regards

... images.

It takes a lot of patience, work, care, talent, etc to capture images like this.

Well done ... congratulations!

A Few Images ... http://www3.sympatico.ca/gord.lange/a_few_images/
 
The wonderful MPE65; unique to Canon as it is the only lens on the market that will go up to 5x magnification, without the need to add extension tubes, teleconvertors, filters, etc.

Kind regards
Stephen
what lenses is it?

your picture is so amazingggggg :)

Stephen,
I have always like your macro work. I have a question or two on your lighting.

Did you have the flash unit mounted to the lens and shoot through the glass?

What did you do to diffuse the light and avoid the flash reflecting off the glass.?

A pic of the set up would be interesting if you have one.

cheers

Thanks Warren, the set up is really quite simple; I will try and post a shot in the next couple of days once I convert the raw files. Basically the flash heads are positioned on a bracket that I made off camera and are situated at either end of the tank. I have Stofen diffusers on the flash heads. As the flashes are at the end of the tank, reflections do not seem a big issue, but I do cover the sides of the Stofens close to the lens with thick cardboard. Some ghosting does occur, and this can be seen in some images, but mostly this can be removed with post processing.

Kind regards
Stephen

...esp. the one which feeds on other species - is it a blood sucker too
in its adult form?

PS I do not see a trace of the banding you've mentioned elsewhere,
at least not at these sizes

very good and actually a scientific work, thanks.

love to shoot both airguns and pictures
 
Outstanding!

Did you ever stop to think, and forget to start again?
 
Hi Quercy, thanks for the compliments. The predacious larval mosquito does not suck blood as an adult; only feeds on plant juices such as nectar.

At the image sizes posted the banding is not obvious, it can only be seen on full size shots. Fortunately for the book I am doing each page is only A5, and so the images will be much smaller and banding will not be noticable

However the sensor staining issue can be seen in the following shot:



If you look carefully, there are two large round spots in this image (which has no cropping, just downsized). One spot is on the right at around 2 o'clock and the other on the lower left closer to the edge of the frame at around 8 o'clock. My 50D also had this but just in the one position; the top right and in almost identical spot to the 7D (which presumably is not a coincidence). Such spotting only becomes evident at magnifications of 3x or more with small f stops.

Kind regards
Stephen
