razorfish: They can make anything work, but the question is if you as a user want lazers scanning your eye a million times a second. I myself will take the side of precaution on this one, as my eyes are rather important to me.

Considering that an earlier implementation of this feature was present on a number of Canon's film cameras several decades ago and there have been no buzz about lawsuits by unhappy photographers damaging their eyesight in the intervening years, I wouldn't worry too much.

Jacques Cornell: "100m"??? That sounds pretty big. What would happen if a 100m asteroid hit the Earth?

@Ellis V: Well, that would not be that far off from the estimate of a 10 km diameter object, so I think it's a reasonable comparison and not really wrong. Some sources speculate about it being even larger, but the 10-ish km estimate seems to be quite popular.

David Cartagena: I would be worried.about using the Eye controlled AF if it is radiating IR light.
I hope they have tested it properly to avoid any eye damage or irritation.

"Near‐Infrared Exposure and Cataracts
The most common eye disease associated with near-infrared radiation is cataracts. Prolonged exposure to IR radiation causes a gradual but irreversible opacity of the lens. Other forms of damage to the eye from IR exposure include scotoma, which is a loss of vision due to the damage to the retina. Even low-level IR absorption can cause symptoms such as redness of the eye, swelling, or hemorrhaging"

https://ehs.lbl.gov/resource/documents/radiation-protection/non-ionizing-radiation/light-and-infrared-radiation/

I wouldn't be surprised if the actual levels of NIR exposure per unit of time would be less than what the eyes encounter during a sunny day outside. But of course this is just speculation from my part and it would be interesting to know to actual specs.

A 100m asteroid impact would be very destructive locally (as in you *really* would not want to be within a few dozen kilometres of it), but for comparison the one that nuked dinosaurs was about 10 km in size.

Gray Photography: Canon had eye control focus on the old EOS-3 film body. You had to train it and then it almost worked sometimes. It was a gimmick imo, though I Ioved the camera, I never used it. Too unreliable. Maybe they've fixed it up in the years since. Maybe it's still a gimmick.

Well, a quote from the article itself seems to answer that: "So is it a gimmick? No. Not by a long shot."

steelhead3: I wonder if eye focusing is causing the poor performance of that huge heavy battery to have such a dismal life.

I'd assume the eye control AF hardware has essentially zero impact on the power consumption besides the time it's intentionally activated by the user. No need to keep it powered up all the time.

Beautiful. Even though I've seen auroras fairly often as someone living quite far north, this view is just on a different level!

Funny Valentine: Even smartphones these days have better AF motors than Canon RF STM lenses.
It's amazing how low end smartphone companies are surpassing specialised camera companies.

Funny Valentine: Out of curiosity, what's your actual definition criteria for better AF motors?

Funny Valentine: I knew this video was going to be misleading even before watching. They didn't even mention the advantageous full well capacity of low megapixel sensors once.

Also the a7sIII files have more leeway for shadow and highlight recovery than the a7rIV. Very useful for landscape shots.

Also there are experiments showing the 12mp Sony a7sIII outresolving the 100 mp Fuji GFX100S.

BasilG: No worries, to be honest my comment is also a bit ambiguous until the end, so it's not hard to misinterpret which video I meant.

BasilG: Just checking, do you mean the original DPR TV video, or the one Funny V linked? My opinion was about the second one.

Regarding that video, it looks like they just look at the prints (or the screen) quickly at an arms length, rather than look closely and take their time. I didn't listen for the audio, but it also seems that they use the corresponding camera's JPEG rendition as a starting point. I don't personally have an idea about the quality of the lenses they've used on the corresponding cameras vs. each other.

I can easily accept the premise that the importance of the number of megapixels is often blown out of proportion , but I don't really think that video validates the concept of the Sony out-resolving the GFX100s.

"Also there are experiments showing the 12mp Sony a7sIII outresolving the 100 mp Fuji GFX100S."

I'd like to see a source for this, since it frankly sounds very odd.

Anastigmat: If everything is flying apart according to the Big Bang Theory, then why are these galaxies colliding. Often scientists liken the expanding universe to a balloon being inflated. If so, then you can paint dots on the surface of the balloon and none of then should ever touch each other. The fact that Andromeda is on a collision course with our Milky Way also demonstrates how ludicrous the Big Bang Theory is. In fact, scientists have to invent something unusual, unknown and unproven, called dark energy and dark matter, in order to save the Big Bang Theory from the trash can. Historians of the future will have a lot of work trying to figure out what went wrong with the minds of the scientists who treat the Big Bang Theory as unchallengeable objective truth when there is clear evidence that contradicts it. In fact, many physicists have believes, such as parallel universes and multiple universes, that are weirder than astrology.

Our current physics models break down at the extreme temperatures and energy densities involved at Big Bang and for a short period of time after, so currently there is no real consensus about what made the Big Bang happen, or what was before, even if some hypotheses about that are more popular than others.

Kind of like finding a dead person with no obvious cause of death, and no immediate access to sophisticated medical equipment; your observations indicate that the death happened, but you can't yet tell the exact reason, just rule some causes out as impossible or very improbable ("his head is intact, so it wasn't a guillotine").

You should read this: https://en.m.wikipedia.org/wiki/Hubble%27s_law

But in short, over "short" distances (in a cosmological sense) effects of gravitational interaction have larger effect than the expansion of the universe.

It's nice to have options in the camera market. However, while the large touchscreen is undoubtedly nice, would it really have hurt to have at least a single physical control wheel on the device to e.g. adjust aperture while in Av mode, shutter speed in shutter priority mode etc? Obviously for fairly static conditions using touchscreen to adjust things is fine, but things can get quite clumsy e.g. if you're trying to use the touchscreen while shooting and tracking something.

Of course if the user only ever uses the camera in automatic mode the point is moot, but I'm assuming people who'd be interested about this would also be more interested about some degree of manual control.

Mr Bolton: People often complain about DT being difficult to use or not working how they'd expect (you know, like LR or PS) but it's really just a matter of learning the interface. When I used Photoshop on a Mac back in the '90s, and then again in the '00s, there was a learning curve. I got to grips with Photoshop CS7 when it came as a free trial on a magazine coverdisc (remember those)? but I don't recall it being particularly intuitive at first.

The point is that it's a little unfair to install DT, spend 20 minutes and then say "Oh, this doesn't work right." or "Oh, the UI sucks." The software works fine, and the UI doesn't suck-it just takes some getting used to.

Spend a few days, read the instructions, give it a chance. You'll be glad you did.

HowaboutRAW: Sure, the stats (and links) for the currently open and already closed issues in 5.9 are actually in the same link that I shared in an earlier comment too, i.e. https://github.com/Beep6581/RawTherapee/milestone/9

Of course just the number of handled issues in any release is a somewhat limited metric since the there's a lot of variation in how little or much effort individual issues need, but to some extent it averages out.

@HowaboutRAW: It should be noted that the upcoming 5.9 milestone currently has 106 closed issues (and 43 open ones). For comparison, 5.8 had 62 and 5.7 47, so 5.9 already has almost as many closed issues than 5.8 and 5.7 combined. In that sense it's not really surprising that the time gap between 5.8 and 5.9 is significantly longer than usual too.

Andyyy: Software like this should have a paid version. Maybe that way they would have more resources to make better software.

It's possible to donate to Darktable development, so anyone who wishes to contribute to their resources can do so. I recall having seen a donation link for them somewhere.

@HowAboutRAW:

even though the time gap between releases is indeed larger than it has usually been, RawTherapee is still alive; see

https://github.com/Beep6581/RawTherapee/milestone/9

for a rough indication about the progress for the next release.

BrentSchumer: I skipped Instagram and consider Twitter an abomination of UI and content.

Totally happy to continue sharing on Flickr, Facebook, and sometimes DPR.

Nice to know I'm not the only person who feels like Twitter's UI is particularly unpleasant. And this comes from a person who is comfortable with Emacs and Vi ;)
