Yes, but as their name implies motion picture are moving images, we hardly have the time to perceive defects. Same as today's 1080p TV that show a 4Mpix image.

@EuriPinhollow Come to think of it, I even have an old ID on one such forum (not used in years...). Thanks for the heads up.

Any place where I can check the compatibility ofspecific Sigma lenses with a Canon EF mount with Canon RF cameras (assuming the Canon adapter ring, of course)? I have been told it is quite the lottery?

These are 8mm movie cameras. See for instance this. Why together? Possibly because its cheaper/more practical to shoot the same scene with 4 cameras than to duplicate the films.

@scottbb About this. Perfectly valid question. It not just the post processing, it is also what kind of pictures can be processed that way, and how you would shoot the initial picture if you know your will be doing this downstream.

@MichaelC The OP was a seasoned user, so if he deleted the question he may have considered there was some sense to my remark. OK it was a photo, but any image would have had the same problem so the answer is not photo-specific and can exist elsewhere. The post was also lacking critical information: OS, display application, actual hardware. Glad you counter-voted, this is what the votes are for.

... What is left is the tricky questions whether because they are really difficult or because the OP is just looking at the wrong side of the problem.

If the previous answer was any good, why would people re-ask the question? Fairly constant behavior for all these sites, some new subject comes up (digital photography, HDR, antigravity tripod...), you get 6 months of carpet-bombing with the easy questions, and then the questions trickle down because those that most people ask have easy-to-find answers.

@Hueco @MichaelC Don't we need a question-answer about the different versions of the Canon 18-55mm lens? And I would avoid the past tense because some of these lenses are still sold on Amazon:)

I don't find it very good() but goodness is not a criteria for sharing, at least on PSE, where it can be a starting point for many questions. () because: dirty background, body cut off, head too centered, taken from above...

@uhoh What kind of camera is that?
xenoid
Dec 27, 2019 22:36
@Hueco The darkroom is more Lightroom/RawTherapee/DarkTable these days. In Meta @rackandboneman still has a point about splitting PSE between "capturing" and "post-production", since a lot of the post is common with images from other sources (CGI or stock). IMHO there is a triangle between PSE (capturing and enhancing the capture), GDSE (imagining/producing synthetic images) and a third pole to be defined for general editing and printing. But the three sides are rather fuzzy.

What amazes me most in this corner of the SE woods is the people who invest large sums of money in devices they for which they haven't got single usage clue. Also the "film is cool" crowd that hardly knows how to operate a camera. Looks like film is the "Kali Linux" of PSE.

@watchme When collapsed my monopod is 41cm (47cm including the head). But nobody says it has to be vertical, once you have added a head (single axis or ballhead). IMHO still the best overall compromise. Of course for specific pictures specific gear can be better.

My cheap one is still alive and kicking after 7 years of abuse (sand, salt water, long walks..). Got a Manfrotto because it is lighter and 10cm higher. I tend to purchase cheap versions of things to try the concept, and switch to brand stuff if I'm happy (and the price is justified).
xenoid

@watchme Gorillapod not useful for this IMHO.
xenoid
Aug 6, 2019 13:27
@watchme Monopod, from $16 on Amazon. Add a Manfrotto 234 Monopod head or equivalent. Don't see much difference when shooting between monopods. The difference is when not shooting (can they be used as a walking stick? Weight? Bulk?).
xenoid
Aug 6, 2019 13:21
@Watchme the ideal solution is a monopod... adds a lot of stability to your lens, and easy to move around. And you don't need to put it on the ground, just push it against any stable support (that can be the tree on your side, for instance). Not very expensive to boot, but you often have to add a head (one with one single axis, to tilt your lens up/down).

@bjonas Typically you should be around 1/250s when shooting propeller planes, and as MciahelC says, this means a good panning. In air shows, I set my Tv mode to 1/250s and my Av to f/8, then quickly switch between Av (jet) and Tv (propeller)
xenoid
Aug 6, 2019 13:14
@watchme If you shoot in nature (bugs..) the autofocus is really useful. IS a bit less so unless you shoot rather still insects. I use the non-IS Canon 100mm macro (450D then 70D), one of my favorite lenses. I also recently purchased the Canon 35mm macro that gives you a different perspective (you are much closer, almost inside the subject).

They still sell these things. I even hacked one to trigger my camera (I was trying to take pictures of lighnings)

@MarkMorganLloyd lenses focal length is expressed in millimeters even in the US so using millimetres isn't so foreign to american photographers.

One suggestion I have seen is to reduce the MTU on the USB interface on your Linux (see ip link set mtu ...). It has to be smaller than other MTUs on the path (see this for some MTU sizes).

Still, fairly trivial (this was the 3rd round of edits...). Could be worth it only for an active question. 2015-era Ubuntu is EOL too (16.04LTS is EOL...).

@Zanna What is the purpose of making trivial edits to a question which is 7 years old and is about a release that is not supported anymore? It puts it under our noses while there is little we can do about it. If something had to be done it could have been to delete the question entirely (no accepted answer).

I think this question was closed as duplicate in error by @DavidPostill . The duplicate question is a different problem. In the closed question, the user has distinct layers, and in the pointed to question you are told to put things on distinct layers.

Strange. Even an empty directory1 should report !=0. Is this a regular Linux filesystem?
xenoid
Dec 24, 2019 11:13
is basename -a dir2/* producing a non-empty list? Is du -s dir1 reporting the riht size for dir1 without exclusions? If you use in your script, you of course have to use variable names instead... $dir1, $dir2.
xenoid
Dec 24, 2019 11:13
Please answer my other two questions in the comment above. Also try to run it at least once in the command line, just to see how it works.
xenoid
Dec 24, 2019 11:13
And what command do you use exactly? Because the edge cases are nothing (dir2/* matches nothing) or a 4 or another small number (the size of the directory inode itself) if dir1 is empty or all the files in it are excluded.
