Blow it up a bit


Well the macro learning curve is steeper than I remember. More like a ski slope, but it helps to keep the leeeeetle grey cells working.

I made this in the late 1980s during a fly tying course at Aberdeen. I really enjoyed making and using my own flies, especially when devising something new with the materials that were becoming popular, departing from the classic patterns. I made many into brooches, which didn't go down well with the boss as she isn't into pearls and twin sets.

If this had been taken with just one image then only a slice would have been in focus, the rest would have gradually blurred as the focal point was moved away from.
Now imagine leaving the focus where it is, and the lighting. Move the camera backwards on a rail system Rail and then move it forwards by increments of about 1mm and take an image using a remote controller wire. (Stops vibration). Take about 25 images, place the stack of images in Helicon Focus and let the clever jiggery pokery produce an image which is in focus throughout it's length.

If this seems a tad over the top, or you can't get it straight in your head imagine how an MRI scanner works, taking slices across a part of the body, then compiling an image for the doctors to pore over. This is very similar, and as I hope to prove soon, can be done in 3D as well.

If you want to see the setup go back to yesterday's Blip. :-)
