Thank you Shiv! Very interesting. Look forward to working through this calculation & experiment more.
Shiv, very informative and simply explained, thank you.
Thank you, your feedback is most appreciated.
Wonderful tutorial for someone like me who is just getting to know this area of photography ! I am already a fan 🙂
Thank you Sunny VIVI - most appreciated.
Shiv - This video was exactly what I was looking for from an instructional perspective on how to use a macro rail. Too many promise to tell you how to do it but don't deliver the details and why behind it. Thanks!
Hi Matt, Thank you for your feedback and kind words. Truly appreciated. Shiv
Many thanks for walking us through the process. I think having a decent focusing rail is critical capturing the source images
You are most welcome,
always something to learn from you Shiv, Thanks
Thank you Lewis - appreciated.
Thanks very much for this video. It was very helpful in my understanding of how to better my macro photography. This is the first video I was able to find that addressed macro rail and focus stacking together.
Thanks for the feedback Jason. Much appreciated.
Thanks Shiv.
Appreciated Roy. Regards.
Excellent information! This will work so well for my product and macro photos!
I am so glad this was of some help. Regards.
I found this really useful, clear and instructive, thank you 🙏
Thank you for your feedback, Toby. Most appreciated.
well described and presented, thanks for sharing
Thank you, Richard. Appreciated.
Fantastic video, thank you very much Shiv!
Appreciate your comment - thank you, Jay.
Very well done, Shiv. Thank you.
Thank you for your kind words. Regards.
THANK you very much! Authoritative! Merci.
You are most welcome Jules - your comment is appreciated.
In the part of your video where you were showing the effects of expansion as the focus rail is moved incrementally forward was cut off with some other misc music information. Wondering what needs to be done to correct for expansion of the image when using a focus rail?
The only way to counter this effect is to make sure you frame your image properly. The subject must remain in the frame at both its closest as well as its most distant point of focus. Now when you bring the images into your stacking software the entire subject will be resolved correctly. Hope this helps.
Thanks so much Shiv for this excellent video. I'd like point out some detail when you perform calculation using the formula : since magnification is .5 then m+1 is 1.5 instead of 2 . Is this ok? Thanks so much once again
Thank you for your feedback. Yes, if the magnification is .5 then 1.5 is correct.
An excellent explanation. With one question. Please explain why the formulas do not match up in the two slides. considering on the part that says (m+1)/m*m. In the next slide for a mag of 0.5, you show 2/0.5, which works out to (1.5+m)/m
Thank you for your comment - it is most appreciated. The second formula is based on the fact the lens in use is not a 1:1 Macro lens but a .5 or half macro hence the variation in the formula.
This was extremely informative and timely for me. Should I assume that my 50mm lenses magnification factor is 1 mounted on a 10mm extension tube? Thank you for this information. I'll be following your future tutorials.
Thank you for your kind words. An extension tube increases lens magnification by an amount equal to the extension distance divided by the lens focal length. So adding a 10 mm extension tube to a 50 mm lens will give a magnification gain of 0.2X. Therefore, if the lens's original magnification was 0.15X, then the new magnification will be 0.15X+0.20X=0.35X
@@ShivVermaphotography Thank you for that. One more question, if I may, is there a chart showing the magnification gain for the different extension tubes? For instance, my set has three, a 10, 16, and 21 mm. What I would like to know is the different magnification gain for each one and in combination with each other. Or do you know of a formula to figure that out?
Thanks for the good explanation for taking macro photos as a beginner. Are you satisfied with the used Focusing Rail.
I am still looking for a good rail for Focus Stacking.
The best one I have used is from Novoflex.
Very helpful
Thank you - your feedback is most appreciated.
Thanks! Curious as to how the initial calculations are done when a macro tube of Xmm is brought into the setup? Is it just re-calculating the CoC and using the same approach?
Not sure as to your question - if you use the DOF calculator you will need to include the extention tube's magnification factor just as you would for bellows.
@@ShivVermaphotography Thanks! I was referring to the photographer's friend app. Where in the app would one compensate or adjust for extension tubes? On a related note, I've found a great calculator that seems accommodate the settings I needed (extension tube and the 33x44 sensor).

Thanks for the great video, by the way!
Thank you Shiv. I found your video very useful and informative. I am just getting into macro photography so carrying out lots of research! I have ordered a 'NiSi' focusing rail which should arrive in the next day or so - it has excellent reviews and not too expensive. Have a look on NiSi's website and see what you think.
I tried your Helicon Soft discount coupon code 45K2D4682G but unfortunately it was invalid when I tried using on Helicon's website. Would you have another code which will work?
Regret that Helicon Soft has discontinued their discount program. My apologies.
Whats the better option between this and the built in focus stacking from a lumix g9?
If your lens has focus breathing then the focusing rail is better. If the lens has no breathing issue then they both work equally well. Regards.
@@ShivVermaphotography oh my! What is focus breathing?? I intend to use three different macro lenses which I have. My simplest is a Nikon 55mm f/3.5 macro;=next is my AF Macro Nikkor ED 200mm f/4 (as I think I recall); an$ lastly my Apo Macro-Elmarit 2.8 100mm Leica-R lens. Any of those “breathe?”
A lesson in physics demonstrated using a camera. Certainly not photography
@@motorvelo Thank you for your appreciation of science in photography. After all, optics is all physics and image capture was all chemistry and now it is electronics.
I lost track when you ran an ad.
Sorry about that but the ads are placed by UA-cam not by me.
@@ShivVermaphotography No, you advertised something.
