Hi everyone,

Last one for today:

This is another 2-frame macromosaic assembled using Photomerge in CS3. Same parameters as the last one except that Photomerge did this one automatically, and I had to hand-assemble the last one (which was no fun at all).

Greg

Hi Greg,

Apologies for drifting slightly off-topic, and this question isn't prompted by your image, but have you ever tried focus stacking using a program such as DSLR Remote Pro to control the camera?

Bob.

Hi Bob,

No I haven't - yet I am of course painfully aware of the depth of field problems doing macro work, and it would be really good to see a big 3-D object taken with a macro lens in good focus right through its depth (thickness). So I am almost certainly going to try this out.

I have wasted quite a lot of time proving what others have said long ago - it ain't worth working at much above f#22 or you get too many problems from diffraction. Unfortunately I always seem to have to prove things for myself before I believe them - but this one seems to be true.

I think I might already have (free) software on the computer that will handle this but simply haven't got round to looking at it yet. I think it was called CZM. Whatever - it's definitely something to have a go with for sure.

Greg

Hi Greg,

I haven't tried the technique but you are right, CombineZM is one of the two utilities suggested on the DSLR Remote Pro page for combining the images.

Bob.
