Cool, I bought the new version of ACDSee Ultimate 2022 and enjoy your style of teaching. Looking forward in learning more about the new version of software. I always wanted to know about focus stacking so thanks for these lessons.
Hi Alec, At 5:08 into the video you mention the camera's VR/IS causing problems when the camera is mounted on a tripod. I have read a number of articles over the last few years where folks have commented that the camera can sense the lack of movement when it is mounted on a tripod and "knows" when to "shut off" image stabilization. Maybe I misunderstood what I was reading. Can you go into a little detail on that? Using Canon 80D / Canon 60D Thanks, Art
Hi Art! I haven't used a Canon in a little while, but I can say with certainty that I can see a difference - at times- in images on Sony between with IS on and off on a tripod. As far as the camera "knowing" that it is on a tripod, the lens on Canons is where the stabilization is (in Sony it's a stabilized chip and sometimes a lens) I'm not sure what this would mean with older lenses, I 100% know this was a problem. I have no doubt that technicians in the know between lens and model combinations could speak to this with authority that I cannot. That said, I 100% know if I turn off stabilization, it is turned off... I would probably never rely on an autopilot system ... even if the technicians told me it was there. ;-)
John, great videos both part I and II. I'm glad ACDSee has added this auto feature. Is the lack of sharpness on your f22 shots more to do with de-fraction than actually sweet spot of the lens. On high quality lenses with rounded apertures and on a FF camera, I believe the rule of thumb is no greater than f16 (f11 for APSC). Some studies I've seen will suggest even a stop lower (f11/f8).
HI Bill! Good observation, yes, you are correct, it is diffraction; that was me being inaccurate with language! It could also easily be diffraction AND vibration. Shooting macro with longer shutters and existing light, the floor could have been moving from my camera operator too. It's fair to say this could happen to anyone and its advantageous to shoot in the sharpest range and at a higher shutter speed anyway -just unfair to Sony as their lens may fair better than is being shown - I don't actually know the answer in this case. Will have to try on a concrete studio floor.
Really like your videos easy to understand and straight to the point. Thank you for not wasting 3 minutes of my precious time

Great information looking ahead to more videos
Thanks Bill - if you have any techniques you want me to delve into - please let me know!

@@alecwatson9215 Thanks for the quick reply! I guess I need to experiment a bit. :-)
