Re: Ant eyes

Was there any "stacking" involved in these photos at all? The entire image seems to be in focus. Most definitely. Here is a single image from the 20X z-stack for the black ant.This particular "stack" took 101 images to get what I needed. http://www.krebsmicro.com/forumpix/2009-1frame.jpg The object...

Re: Ant eyes

Thanks for the kind remarks. Incredibly crisp and defined. How did you light these? Fan has it just about correct with some minor but key differences from the earlier post he referenced. With a subject like this I have two (somewhat conflicting) lighting "needs". Evenly diffused overall light works ...

Ant eyes

It's a common subject and one I've done several times over the years. But when you are working with a "new" ant it is hard to pass up taking a few tight shots!

Re: May need a phase contrast 'scope soon, I'm in the UK...

my first intention, as soon as I get a chance, is to learn more of simple oblique technique as possible with my current rig Everything you have gotten here is good advice. I would strongly recommend taking up the offers to give you some PC examples from your slides. The ease with which oblique can ...

Re: Daphnia

Were those simple darkfield, or DIC with black background? what type of camera did you use to capture the photo? The camera was a Canon T3i. The microscope was a "hybrid" Nikon MM-11/Olympus scope I use a great deal. You can see the scope below. http://www.krebsmicro.com/forumpix/mm11hybrid.jpg It ...

Re: VERY glad to be back!

Good variety of subjects and very nice images. #4 is a Keratella rotifer (genus). Possibly Keratella cochlearis... but I'm always hesitant to go as far as exact species. #6 is definitely a Closterium. There are many species with this long skinny "bow" shape. (Closterium acutum and Closterium keutzin...

Charles,

There is really only one that I am aware of that is called "Stereo Photo Maker". It is generally highly regarded and recommended:

Re: Image stacking question

gekko: wonder if there is a way (i.e. a setting of the stacking program) to make the stack more "opaque" so what is above hides what is below, or would that be nonsensical or at least not useful? Any ideas? Some years ago I tried a stacking program named AllFocus from a company called Saphicon. What...
