it actually wasn't too windy -- if it was windy the waves would have been a LOT bigger!

Glad you found it useful!

You're not alone

Ha ha! Yeah, my videos are kinda wide in content :-)

When you try a good comparison, I'd love to hear the results so come back and post your findings!

True, but if you note in my conclusion: all lenses and cameras would need to be tested as each is different. The software and equipment per combination needs testing, so even if I had tested one camera with IBIS, it wouldn't necessarily match another camera (or even another firmware version potentially for that matter). So the conclusion remains the same: test all combinations that YOU use.

I've wondered that too. I don't have a body image stabilization camera to try. It may vary per brand and model too though

Greetings Kevin. Your point is perfectly valid if all that I was looking during my tests was the strands of tall grasses, etc. I selected the grasses for the video since they're sharp and distinct and easy for viewers to see the differences in even with youtube video compression and other video artifacts possibly getting in the way. Everyone should always look at everything within the focal plane, like I did, and take multiple example shots, like I did, when testing your own equipment. But I'm afraid you entirely missed the bigger point of my message: you should test your own equipment and not take any general statement as fact. You absolutely should not accept my results as fact for your equipment as in the video I showed clearly that results differ based on lens and camera IS technologies in play. BTW, I agree that remaining still while the shots were taking (and using a timer and/or shutter release starting with the mirror up) is also critical. Which is why I wasn't "walking around" either.

Ha! I hadn't considered that. If you always shoot from a tripod, you might be right!

Well certainly my point in the video is to try and determine yourself what is best for your equipment is key.

@@WesHardaker I think I figured out the problem.... my tripod sucks with the weight I've put on it. Might be time to get a Manfrotto

@@ArcanePath360 Actually, you bring up an interesting point. Certainly when you change tripods I'd be tempted to test everything again. But I hadn't considered trying it with and without a weight pulling down on the tripod. Especially if it's a swinging weight it could have an interesting impact.

@@WesHardaker With the weight, I was referring to the heavy lens weighing about 2kg. My tripod doesn't seem to be up to the job, unless I fully push in the feet and centre column. Just been taking more pics of the moon tonight. With the tripod more stable now and the ball head off to one side, it's a lot sturdier, and IS off did work better I think, but was really hit and miss. It's difficult to tell when clouds occasionally mist up your shot and make it look like motion blur. I would say my further tests are inconclusive. I do know that the IS doesn't always give good results when I'm leaning the lens against something and it's better turned off with a high shutter rate

Whoops; meant to put that in the description (and just did): Music: Shine - "Everything seems to shine in this meditative state" - Onycs

Thanks,@@WesHardaker. Looking forward to more of your aerial adventures. 😉

That's a good point to consider, but as I mentioned in the video it almost certainly depends on the lens (at least, and potentially the camera though less likely with common DSLRs that I know of). Anyway, if lenses do that, yes it would mean that my tests were inconclusive if I couldn't tell a difference and that it might be the IS auto turning off. However, for the lens I used in this video it clearly showed a difference, which to me proved that this lens definitely didn't turn off IS.

Yep, and not only that but try taking a long exposure picture of the ocean with crashing waves. The waves will nicely blend. So will everything else in the picture as your tripod jiggles.

To conclude, don't believe one answer as truth and test your equipment and your tripod together. The answer for one person may be different than yours.

Just as Wes answered, it's best to test your lenses. All my Fuji lenses benefit from turning IS off on a tripod. ONE of my Nikkor lenses didn't care at all, the rest wanted IS off. I nearly botched a shot just a day ago (hence, me being here) where an entire session of shooting a commercial building had unsharp images. Thankfully, the target platform and format rendered the unsharpness invisible, so I didn't have to go back and reshoot. 😁

Super glad it helped you out!

The programmer side of knows its likely possible and have had the same question. I suspect in the future we may see such optimizations but as of this time I don't know of any system that does such intelligence today.

Why would something intended to improve stability activate at all if the camera isn't moving? I'd figure the system should simply detect stability/movement and apply stabilization *if* necessary. If IS causes pictures to be blurry when the pictures are sharp with IS turned off that tells me that there's a more general problem with how IS works. Maybe it's the algorithm, maybe it's the equipment, or maybe it's the design (for example the algorithm might be doing exactly what it was intended to do).

I think it's a much more subtle problem than that. There likely *is* some shake on a tripod, but the algorithm is overcompensating the other direction expecting to be worse than it is. Sensor accuracy of any time is never zero, thus it's unlikely that it would detect zero shake for N seconds, but rather "small". I agree that they could likely improve the algorithm, but remember that these are not high end processing devices. They're aiming for simple and fast. And any time you optimize for one direction (detecting a tripod), you'll like make a mistake in the other direction (sometimes thinking you're on a tripod when you're not). If you had the best IS accuracy for hand-held and assumed that the user could turn off the IS switch when on a tripod, that would be a reasonable design decision if you were trying to maximize for hand-held shake reduction.

Glad you enjoyed it!

M Mohan that's an excellent question and I'd have to do studies both in wind and without to test it. It maybe that the wind adds enough vibrations for SOME lenses to fix the VR/IR so it works better with it on again. I suspect every lens is different, which is what I show in this video: you need to test each lens.

Super glad it was helpful to you!

Please don't do that!!! ha ha.

TheMrBennito the whole point of my video is that you have to test each combination to be sure of they perform. I could see your proposed test going either way since if it is hand on one end, IS should be active for that part but if the lens is resting on the window, that's where vibrations may conflict. My guess is since it isn't clamped down it should probably be on. But again, I'd test to be sure. Good luck! Interesting question.

you're right. Implying I would have to do 4 tests. why not :)

Super glad you found it so useful and you got some real-world benefit out of it!

Sadly, active development has not happened in a while, as the funding source that the development team was using went away.

No, applications know the trust system of the DNS and use that mechanism to look up signatures used by example.com. So browsers would know only the root trust of the DNS and would then use the DNS trust chain to look up an additional path to example.com's https (TLS) certificate. However, sadly, browsers haven't adopted DANE and don't look like they will anytime soon as they're fighting the notion. Mail (SMTP) usage of DANE, on the other hand, is growing rapidly.

Thank you, Iam reading through RFC 6698 to understand DANE further. Iam writing a report on dane. I have emailed you the same question on the email address provided on youtube. Will it be okay if I ask you more about Dane in future if required?

You can, though my time is somewhat limited so extensive questions would be harder. Make sure you read a bunch of the RFCs and tutorials before you send lots of questions to people.

Jacek Pilarski awesome! So glad it helped your image quality!

+birdie399 Glad you enjoyed it. I was surprised by the results myself!

+Carl Crumley Thanks! My goal in teaching has always been to teach the "why"s more than the "how"s.
