It’s not really about being justified, it’s about being gentler with people. We don’t have to jump all over each other, there is another way.
I think OP will live.
Should that be the standard we hold ourselves to?

#72All of them are extreme close up shots. I am guessing those are the ones that ended up being interesting may be?
That's what macrophotography means.

Sure you can. The f-stop is the ratio of focal length to aperture diameter. A aperture of f/4 means, the aperture is one fourth of the focal length. At the same f-stop, you get the same light density on the sensor surface. The catch is: a phone has a much smaller sensor, so at the same f-stop, across the whole sensor less light is gathered and consequently, you have a weaker signal.
Wait until you start looking at transmission values... f-stop doesn't mean much other than the maximum that the aperture for that lens can open. It doesn't indicate lens or element quality, or aberrations. There's a reason that pixel peeping, gear games, and reviewers are so prevalent in high end photography. As a simple extension to this, most of my lenses work better a few stops before maximum f-stop. So, yes, but…
In practice, light gathering correlates to F-stop quite well on most normal modern lenses, transmission losses are very low. The main exceptions are deliberately apodized lenses, which have considerably transmission losses wide open.
For the rest - yeah, f# is just one of important specifications.

All Macro photography requires extra light, it's not just anything to do specific to cell phones. That's why there are so many flash rigs designed for this. Also, the iPhone 13 camera has ridiculously fast lenses[0]: Pro 12MP camera system: Telephoto, Wide, and Ultra Wide cameras Telephoto: ƒ/2.8 aperture Wide: ƒ/1.5 aperture Ultra Wide: ƒ/1.8 aperture and 120° field of view If you search for lenses for "real" camera…
Just a meta-comment, but your reply was really good until the last sentence. > Sounds like you need some more research into macrophotography That undermined your otherwise very factual rebuttal/clarification because it seems like at best an impossible standard (everybody could always use more research into anything), and at worst a "you don't know as much as me" veiled in professionalism/passive aggressiveness. The i…
I know you think what you're doing is "elevating" conversations, but ... "calling out" people for the slightest bit of negativity is an extremely toxic behavior. Quality discourse requires negativity and fosters a healthy span of tolerance for it. Your interpretation is also very narrow and passive aggressive itself, to me it seems completely neutral that in a case when someone has a strong opinion based on ignorance, you remind them of their ignorance - not just for people reading it but for their own sake.

#75If I counted correctly, 8/10 of the selected submissions specifically mention the iPhone and the macro feature by name. Same with the comments on different submissions. Okay, okay, I know, it's Apple, this is a marketing campaign. I guess next time, I'm going to take a photo of the contents of my fridge, with the caption: "Every morning, when I check my new iPhone 14 Pro Max Plus, I'm filled with a sense of inspirati…
"It's your first day of school Jimmy, show me that smile! You know it's going to come out great on the iPhone 16 Ultra Max, thanks to it's advanced computational photography and new Neural Merge technology! I can even switch it over to the new Pro Portrait mode for a better digital Bokeh on the bus."

#76Half of these are pretty unimpressive. The composition of “A drop of freedom” does not inspire me at all. The only focused area is a boring droplet in the middle and everything is blurry. Probably a million better ways to frame it.
“The Final Bloom” is absolutely beautiful however.
Re: Apple unveils the best photos from the Shot on iPhone Macro Challenge
#77Pretty crazy that you can get this kind of shots with a mobile tbh. Until very recently you would require a DSLR with a bulky specialized lens. For reference this is what a typical macro lens looks like https://images.app.goo.gl/nf5keSiugxyb2pmA6
The issue is the working distance. You'll note that the photographer there is shooing with a lens that has a fairly long barrel. For the Nikkor 105mm macro lens - https://coinimaging.com/nikon_105vr.html At 1:1, there's 15.3 cm between the front of the lens and the subject. But if you're shooting with a rather short lens (e.g. those in the camera of a phone) then the working distance is very close. This becomes impor…
The practical working distance is why I like the four-thirds system for macro. With a 50mm 1:2 macro lens on a micro43 body you can work at a distance of 10-25cm from the lens front, so you can sneak up on bugs, and on this format you can get a useful depth of field with more than a few atoms in focus like you'd get on a larger format.

You were talking about the light being gathered by the lens. That is mostly determined by the f-stop. Technically it is the t-stop, but they should be reasonably close together not to make a huge difference. Quite the contrary, as the phone lens has less elements than some modern camera lens designs, the phone might suffer less from the difference than the camera lens.
The aspects you are now referring to are about the lens quality. Yes, I would expect a real camera lens to be much better than the lens of an iPhone. There is no doubt about that. But in the posting I answered to, you spoke about the comparability of aperture values.
Re: Apple unveils the best photos from the Shot on iPhone Macro Challenge
#79The trick to getting the best out of camera phones is to shore up their weaknesses with external devices. Cell phone cameras are multiple stops slower than "real" cameras (i.e. they take in 1/4 to 1/8th as much light). So you add light to the scene to shore up that weakness. Most of these pictures were probably lit very carefully with high quality lights, or else were taken in bright daylight, and the phone was proba…

I disagree that bigger cameras are better for macrophotography. I say this because of the physics of how light works in macrophotography, which matches my experience doing macrophotography with larger cameras (6x7cm and 4x5"). The long story short is that reducing the aperture has two effects on image sharpness. Smaller apertures increase the depth of field, bringing more of your scene into focus. Smaller apertures a…
This lines up with what Don Don Komarechka says on the subject. His images are fantastic and he shoots micro 4/3.
