Focus stacking is the art of digitally combining a series of images with a narrow depth of field into a single image with an extended depth. How do photographers capture that stunning shot at high magnification and still have great depth of field? Enter focus stacking. Unfortunately macro photographs often suffer from a narrow depth of field. It brings to life detail that the human eye all too often misses. Macro-photography is a fascinating sub-set of the photographic world. amount of focus movement" was turned off in your video, try turning it on and setting a shorter threshold, like 10 or even 5.StackShot - Automated Macro Rail for Focus Stacking I wonder what could have changed that triggered the problem, and I don't know.īy the way, I can see that "Limit max. The only really odd thing about is that you say it used to work before. What I see happening is the lens not respecting the focus adjustment commands with enough precision, and it's not an extraordinary occasion for Tamron lenses especially. I very much doubt there could be such a glaring bug in the program's primary functionality and no one else reported it during all this time, but of course if you can reproduce such an issue and submit evidence we will investigate at once. If you do observer numerical discrepancies - please send a bug report immediately (menu - Help - Report a bug). It does sound weird, but there were no problems on the video you've submitted, all the numbers were correct there and if you were to mask the live view image there would be no indication of anything being wrong: the only problem was that the lens didn't execute the focus movement commands accurately, but the program did send the correct numbers to the lens. If A was at 0 (as it always is) and B was at 189, and then you reset A to +24, then the distance between points (which is what you see listed while both points are locked) should be 189 - 24 = 165, not 223 (189 + 24). This is a bit hard to follow in verbal form.

Hopefully this adds to the puzzle!! Still love the programme idea.just need guarantee of accuracy before i purchase the full license. Point B as a matter of fact is now correct at 236/221. If it had been at 24/223 it might have made more sense!! it has got more out of focus. Even so, because when I bring point A back into focus it is at 37/223. This is where the problem lies as when it moves back to point A it goes 223 points back not the initial correct 189. So, I clear point B and re-set at +24 which then saves the distance as 223 between the two points. If I switch back to check point B, it moves back to 189, but this is now +24 points short. When in stops at 0 it is not focussed on point A any more i have to move point A +24 points to get it back in focus (24/189). When i move from point B back to point A i can see the distance counting down from 189 to 0. Helicon Remote, in the example i have tried today, when points A and B are set and saved, calculates the distance between the nearest and farthest focussing points to be 189. Having factory re-set all camera settings, unfortunately the problem has not been resolved.Īll the variables you mentioned remained constant (aperture, focal length and correction factor). I was convinced this was the programme for focus stacking I had been looking for, but now am a little less convinced! Please help!! I had made no adjustments to either the programme or camera settings, so cannot understand why on day 1 it is fine and day 2 it is not. I have experimented setting both of the points and then flicking between point A and B and it will not accurately make the return focal journey. I have read some similar threads, and adjusted the 'Limit maximum amount of continuous focus movement' to 'Yes' and adjusted the 'Max amount of continuous focus movement' from 75 to 15 as other threads have suggested, but it has made no difference. I have reset the the preferences, re-installed the programme, switched the camera back off and on, cleaned the lens contact points but all to no avail. I would also mention that previously the programme took a lot more shots (100+) but now for similar images it takes about 30. This results in the entire stacked image being out of focus. When I set focal point A as the nearest point, then set Focal point B as the farthest - when I start shooting the camera either overshoots or undershoots Focal point A and does not finish where I set Focal point B. I will start with the fact the the programme was working flawlessly up till now, with the same camera body and lens.
