Now that the insect season is prettymuch at an end in England, I've been playing a little with cross polarisation macro shots. Cross polarisation is where you have polarising film over the lens and a polariser - it cuts out reflections and means you're photographing into the subject.

Quite fun - this was 5mm wide at its top but I angled it so that you're only seeing a 2mm width. On a shot with a polariser but no polarising film you're still seeing a huge light reflection, but none on this. The flash was pointed more or less directly towards the face you're seeing, I've made (yet another) new setup which is working out quite well for me.

Nice depth in the wing casings. They look translucent.

Thomas Shahan has been mentioned in other posts about extreme macro photography here. He is featured in this weeks Flickr blog as he has been published in National Geographic magazine.

He uses a K-x with reversed lenses on extension tubes to get his shots. Thomas, if you are a member here, congrats!

My dream right there.

FWIW Thomas is not a member unless he's joined amidst my absense. Also those images were taken with the lowly K200d, but he now uses a K-x

These are some variations I shot yesterday. The subject isn't the most interesting but that wasn't the point of the exercise, which was about playing with some different diffuser setups, light angles and backgrounds. I figure that if I can get control and satisfaction over those 3 during the months when there are no insects then that should set me up to be able to do ok once the bugs are around.

The light setup is a smallHD field monitor with PC output showing a photoshop gradient. This works ok although there are colour temperature problems especially when using the 3100K Jansjo lights. Getting light right to the very front is still a problem because the working distance lens <==> model doesn't give you the clearance to point a flash that way. I'm looking for various kitchen containers to make a diffuser that I think will solve it but so far no luck, they tend to be the wrong type of plastic or coloured. I tried a pingpong ball but that's making my stuff really yellow. In terms of PP, Topaz detail, NoiseNinja and CS3 seems to be giving me what I need. Topaz is especially useful.

The stacks are all of 30 or so, so not especially deep. I have a newport but the connection pieces to cam and tripod are custom creations and the guy I spoke to is trying to fleece me for a lot of money - so I'm looking for an alternate supplier.

~15 SOOC shots stacked, sharpness set to zero and no PP.

what kind of objective Nass?


I'd love to shoot with my objective again but the pentax M42-microscope adapter I've been borrowing is no longer in my possession:ugh:

A really cheap and nasty noname 10x... really just to test to see what it's like =). Tricky as hell without a micrometer stage. Got myself a little insect examination stage (a needle thing to mount it on), lord it makes things easier. This is a really crappy stack with just 7 shots. Yay!

I've always used styrofoam cups as my wrap around diffusers, cutting a slot in them for the vertical holder to slide in/out
