"Focus stacking using a focusing rail?"


South Australia, AU
          

Hi Guys,
Seriously thinking about purchasing a focusing rail for focus stacking,
Using the graduations engraved on the rail, do you only focus once and move the rail for the next and sequential stacks? Or do you have to focus every stack?
Regards,
Gary

Gary,Don(domer2760)gave an excellent explanation not long ago,if you can find it in the archives.Basically,focus on near end and then using the rail move it so the far end is in focus and calculate the number of slices you will need for the f-stop you are using to cover that given distance.I tried a cheap rail once and was more frustrated with it than anything else but I believe a good rail will get good results.

Hi Gary,

If you use a rail you focus at one extreme (near or far) and then move the rail to another plane of focus within the range of the stack. Repeat until the end of the range is reached. You don't change focus as you move through the range.

When it's done without using a rail, you start the same way by focusing at one extreme then move to another plane of focus by refocusing the lens. The camera position remains fixed.

John

Thank you John,
I had a feeling that would be the best option,
I would like the x + y option from RRS but the single rail will have to do, their duel rail is way over priced

I have their ball and mono heads which I think is value for money, but the macro is somewhat pricey
Regards,
Gary
