tom trinko: Another option:

The camera shows spots in the image that it could focus on, ie there is enough detail, and the spots span the closest objects to the ones farthest away.

by turning one of the dials the camera would jump from focus point to focus point using autofocus at each.

so there's be a spot on the bird and one on the branches in a bird behind branches photo and the user would select the spot on the bird.

I think that would address most cases where Manual focus is needed.

And if once the user picks a spot they can use focus guiding or some other interface to manual fine tune the camera it would address most of the other cases.

I rarely take pictures of people so I didn't think of that.

But you're right if they can do that they should be able to do what I suggested with just a software change.

Reilly Diefenbach: Are all Adobe haters who don't use Adobe products but love to vent their spleen at every opportunity present and accounted for? Gentlemen, start your little engines!

I'm generally a fan of Adobe, my daughter worked for them for awhile and a friend of mine used to be a director there, but a good company would have made this an opt in and asked everyone to join.

That doesn't mean that Adobe is evil but it does mean that they should be critiqued in this case.

p51d007: The Skydo, is a great non China drone, if you want tracking for sports type things.
If you want a good photography drone, the DJI or Autel are superior.

Since we can buy an alternative to Chinese drones we shouldn't because we can't buy an alternative to Chinese manufactured cell phones?

That doesn't make sense does it?

I never use the autonomous flying capabilities of my Skydio 2+ but I still find it's a great drone for capturing stunning video.

Not contributing to the fascist Chinese state which is not only imperialistic but committing genocide is by far the deciding factor for me.

I had a DJI drone but after hearing about how the Chinese have slave labor and are committing genocide I will refrain from buying Chinese products if there is an alternative.

Skydio is a fine alternative.

tom trinko: I've flown my Skidoo 2+ over the ocean many times with no problem.

I have no idea why the review says that it can't be flown over water.

I suspect that if one is flying very low over very still water there could be an issue but that's hardly the same as saying you should avoid flying it over water.

Well I've flown mine over the ocean and over a steam and haven't had any problems.

But I always fly well over 20ft in altitude.

As to video quality I think it's great.

Of course that may be in part due to the fact that when I share it with friends I do so on a 1K TV.

But when I watch the videos on my iMac they look great too.

Are they as good as the 8K video from my R5? No but since I only use the Skydio 2+ as a hobbies I find that the image quality is fine.

Also the fact that it's American made given the slave labor and genocide that's going on in China is a big plus for me.

On article A beginner’s guide to memory cards (157 comments in total)

I think calling CF cards "obsolete" is crazy given that there will be millions of camera's out there that use them for years to come.

It's true that CFExpress is replacing CF but not everyone can afford to go out and buy the next great camera as soon as it comes out.

I think saying that the format is "obsolete" will tend to get people thinking you can no longer buy CF cards which isn't the case.

tom trinko: This amazingly wrong.

They're not seeing through clouds, using what data is available to construct an image, they're showing historical data.

Assuming they can correct for seasonal effects the data would still be useless.

If one is looking for changes to buildings, say due to construction or terrorism, one won't see it; in fact one will be fooled into thinking nothing has changed.

If one is looking for activity trends, how many cars are on the road, once again one will be tricked.

If one is looking for vegetation color, to asses plant health, once again one will be fooled.

I see no value to this that couldn't be accomplished by just providing the historical image data.

I see great danger to this since it could easily fool a data consumer.

I'm familiar with SAR.

However since the SAR images aren't taken at the same time as the visible ones they won't be providing an accurate representation of the location at a given time.

Further the process blends in historic optical imagery which is likely to be wrong if you're looking for temporally changing things.

The AI is actually in the blending models; how the multiple non-cotemperaneous images are combined.

Link | Posted on Dec 11, 2021 at 22:06 UTC

Is this really super resolution or is it assuming that models are valid and replacing real data with model data?

Super resolution can be achieved but once you use AI one is using models which may not be correct.

After paying for real imagery being given imagery that might not be correct if the models are wrong would be a significant let down.

photoaddict: USB-C is the future and is the port to rule all. We need to put an end to non-sense about "innovation" - USB-C is extremely usable and provides plenty of juice - it can deliver 8K@60, and can provide up to 100W. I don't see what the issue is?

The issue is that few people think the government has the authority to tell companies, and consumers, what sort of devices they are allowed to use.

Sure having some government bureaucrats who haven't produced anything anyone has ever wanted to buy define standards for wildly successful products can't go wrong right?

On article Hands-on with the Canon RF 14-35mm F4 L IS USM (402 comments in total)
In reply to:

tom trinko: To whom is a $1700 lens "affordable"?

As a hobbyist I'll stick to the cheap RF adapter and my existing, and far less expensive , wide angle lenses.

Such hostility. :)

Look an R5 isn't affordable either. I can buy only so many "unaffordable" things.

My point wasn't that the lens wasn't a good value only that in my mind the 600 and 800mm lenses and the 24 to 240mm lens are "affordable" and a lens that's around half the cost of the body isn't.

Clearly "affordable is subjective but since I use around 6 lenses if each costs about 1/2 that of the body then that's hardly "affordable" in my opinion.

Not sure how the tipping thing is relevant since as you point out that's part of the price. For what it's worth I don't ever eat if I can't tip; except at In and Out. :)

The problem with Twitter of course is that they've demonstrated that they are fully willing to censor anything they don't like.

I don't have the 600mm but I do have the 800mm.

It's a great lens but it's not good for shooting moving subjects like birds in flight since the field of view is so small.

I normally use a Tamron 150-600mm lens when shooting moving subjects. I find that being able to go to a lower magnification to acquire the target is very helpful.

So my take is that if you're going to spend most of your time taking pictures of relatively stationary objects, such as birds on trees or in nests, and you tend to be far away from them then the 800mm is great.

But if you're going to try and shoot rapidly moving subjects and/or you can get close to your target getting a zoom would be better for a first lens.

Of course I obviously think folks should have both since that's what I do. :)

In reply to:

tom trinko: I agree that drone pilots have to follow the rules.

However I find it hard to believe that the birds are so poorly evolved that they fled their eggs just because a couple of drones crashed.

How would that be worse than say an eagle showing up or any number of other natural phenomena?

A lot of people here apparently have reading comprehension issues:

My very first sentence was "I agree that drone pilots have to follow the rules."

So how people can be saying that I somehow support flying drones where they're not supposed to be flown is unclear to me.

As to blaming the victims my point wasn't that I blamed the birds but that I doubt that two drones crashing into a nesting area would cause the birds to flee permanently. I was questioning the veracity of the report.

But even if the report isn't true that even a few birds were killed by drone pilots flying illegally means that the drone pilots should be punished.

While I understand that we ban people from nesting sites is it really true that no natural predators ever approach nesting sites? If one predator shows up the terns all die? Sounds like terns should have died off a long time ago.
