Halos seem random. What creates or causes the halo effect?

Lightroom 4 to helicon focus file limit

It appears that Focus will not accept more than 60 files from Lightroom 4. if you export the files from Lightroom 4 to a directory then Helicon Focus will happily read them.

Re: Techniques for shooting flowers using extended rail

The NIkon 60 mm micro f2.8 has a very shallow depth of field. between 2.5 mm and 7 mm depending on how close you are to the subject. That being said I have found that I can get acceptable flower pictures with using F16 with a cognisys macro rail movement of 35 mm. I have used 99 frames for a sunflow...

Re: Techniques for shooting flowers using extended rail

Ok still trying to get the technique down. Not successful yet. I there a limitation on the number of input files to the focus stacking program? When I export from lightroom 4 it seems that lightroom 4 indicates 101 files exported but Helicon focus only gets 60. I just noticed this issue so some of m...

Re: Techniques for shooting flowers using extended rail

I found a ftp program smartftp that worked very well with your site. I have uploaded a sample stack for your review and suggestions.

Thanks for the help

Re: Techniques for shooting flowers using extended rail

Assuming the lens is sharp enough does the software work better with f16 or f8? Is it correct to say that the depth of field time the number of steps will equal the maximum in focus depth from the starting position? For example if the flower is 2 cm thick and you want leaves in focus 2 cm beyond the...

Re: Cognisys StackShot

The stackshot seems to work well. I am having problems with depth of field but the hardware works well. I have taken over 700 frames so far without an issue.

Re: Techniques for shooting flowers using extended rail

Thank you. I have not used the remote package yet. I have been using stackshot itself. I apologize for the confusion. I have learned that the depth of field on the Nikon 60 mm micro lens is very small. When you are focused at less than ten inches things get very tricky. I have been doing trial and e...

Re: Techniques for shooting flowers using extended rail

If the depth of field on the 60 mm lens is say 0.189 meters at a given aperature then the distance between shots in your menus should be 90 mm or 0.90 mm?

I think that I just do not have the units entered correctly.

Thanks

Techniques for shooting flowers using extended rail

I have been trying to shoot flowers using a nikon d800e (iso 100) nikkor 60 mm f2.8 micro lens (f8 to f13) manfrotto tripod elichrome quadra rx flash (set at 2.0). I think I am missing something in the technique to get sharp pictures. I focus the first frame very carefully on say the front edge of t...
