No inside info here, but I think it will bear watching for this type of project.

Take a look at Microsoft Photosynth. It may do the stitching for you. http://www.labs.live.com/photosynth/

I just ran across this DIY ringlight using fiber optics: http://fuzzcraft.fuzzphoto.eu/ringlight4-0.html

Is there a good way to determine the best type of fiber optic cable to use for this?

If you have Photoshop, try using one of the "Paint with Light" actions from http://www.atncentral.com. They are actually just dodge and burn actions that can sometimes remove haze and surface glare.

Well that certainly cured the sharpening/contrast problem. Unfortunately it cured it a little too well and the image turned out quite soft. I'll have to play with the settings to see if there's a happy medium :)

I'm curious, though -- what was it about this shot that motivated manual stacking?

Sometimes the output from CombineZ5 looks a little harsh and I haven't progressed very far past the "Do Stack" stage with it.

Viburnum and snoot

Well, I'm sure everyone knows what a viburnum is :) This is manually stacked from 25 images. 35mm macro appx. 1:2 f11 1/80 sec http://img.photobucket.com/albums/v649/etfrench/21937sw.jpg Larger version here: http://img.photobucket.com/albums/v649/etfrench/21937s.jpg And here's the snoot: http://img....

Myself, that's why you can see all the machining marks :) I have a Harbor Freight mini-mill and min-lathe. The first pano head could be built without the mill and lathe, but I used both quite a bit on this one.

I'm curious about the pixel counts. I think I'm hearing 4768x6550 from only 2 frames. That suggests a really big sensor or some resizing after the shoot. What's the story? For some reason, I had ACR output set to 12mp instead of 7.5. I suppose now I'll have to pixel peep to see if there is any deta...

Spherical Pano head/macro rail/lenticular head

Here's version 2 of my spherical pano head. Major changes from the original, http://www.tawbaware.com/forum2/viewtopic.php?t=3508, are: 1. Landscape or Portrait mode: The main reason for adding landscape mode is my Olympus e330 LiveView LCD is a lot easier to use in landscape mode. It also gives mor...

Image size: 4768x6550 pixels or 16x22 inches. The subject is about an inch long and 3/8 inch wide. My spherical pano head has a linear slide on the horizontal arm, so it's pretty straight forward for adjusting distance. I rotated the pano head for the second frame instead of shifting the camera late...

Christmas cactus

Here's the first successful stacked and stitched image that I've done by moving the camera instead of focusing with the lens. It has 2 frames with 30 stacked images. Each image was 1:1.

I was curious how everyone was determining where the entrance pupil was located when shooting between 1:1 and 1:4? It would be nice to be able to take two images, measure the parallax error, then calulate where the entrance pupil is located relative to the current setting. Olympus claims their digit...
