But that's how physics work. If iPhone Macro doesn't suffer the same issues, then it's a software trick

Depth of field is a direct function of real-world focal length. An iPhone has camera systems with a focal length in the 1.4mm - 5mm range (the equivalent framing is not relevant to the impact on DoF). Most SLRs have lenses with focal lengths from 35mm - 100mm. https://www.photopills.com/calculators/dof (That site has different camera selections purely because the circle of confusion differs based upon the sensor size…

You should read up on how crop factor works. It just doesn't work out like that. Try a DOF calculator that allows you to choose the crop factor and set a crop factor of 8.4.

There's a difference in macro being 1:1 ratio (as understood in photography) vs having an AI do something to make something small look big in the image. So if their lenses are not delivering 1:1 but use some sort of algo, then it's misleading.

There are no shortage of lenses that are labeled macro but top out at 1:2, or even 1:4.

Yes, and it's false advertising and an assholes move wether it's Tamron or Apple doing it.

Here's the thing about iPhone photography (and Android too, I suppose): if you know what a DSLR is, or the difference between DSLR and mirrorless bodies, you are not the target audience . Apple isn't trying compete with a $3500 Sony A7R4 with a $1000 90mm macro lens. They're aiming for people who see the example "macro" photos and say "neat! I want to try that". Or the people who have already bought a Moment macro le…

A 200$ used up Sony Nex-3 with a 200$ Mitakon macro will do a much better job. I agree the iPhone is still convenient, but if your goal is to save money, not upgrading and buying a cheap camera is still going to have better results at a lower price, at the expense of convenience.

Yeah I just tried it out and holy shit it's light years better than the default camera app when it come to letting you adjust manual focus and what not. I signed up for the trial. The yearly fee is only $11.99. How did you spend $80?

According to the Halide II App Store landing page[1], a one time purchase is $50. Whether or not it's easily accessible in the app is another story. > In-App Purchases 1. Yearly $11.99 2. Monthly $2.99 3. One Time Purchase $49.99 [1] https://apps.apple.com/us/app/halide-mark-ii-pro-camera/id88...

I just downloaded it today. First thing you do when you open it is choose which of those three you want to pay (or start the free trial with a cancellable auto-subscribe for the yearly), do the 2-second Apple Pay prompt, then it sends you right to the camera.

That is to say, the one-time was immediately easily accessible.

I think that's largely true -- if you frequently need to take professional macro shots, you'll already have your own, better setup anyhow, and won't be switching to a phone camera anytime soon. However, somewhat surprisingly (for me at least), this seems to actually be good enough to also satisfy those that do carry fancy cameras, but don't need to take macro shots that often... from https://austinmann.com/trek/iphon…

no, the difference between a full-frame DSLR and any phone camera is night and day. It's just ridiculous to read articles about phone cameras with their ugly photos where authors are writing something like “wow it's amazing - best camera ever, you don't need a pro camera anymore”. It's so funny.

DSLRs use extensive such tricks to process the image. Enthusiast groups will show the pathological cases for the image processing that happens. Ultimately, ceci n'est pas une pipe applies to the picture. It's a representation and it is meant to evoke the scene.

What DSLRs use AI or other software based tricks to perform macro photography?

Name a DSLR and it uses software based tricks to perform all photography.

And when it's good, it's good. I just clicked buy on Halide. I'd downloaded and played with it back when I got my iPhoneXR, and I only upgraded from that recently purely because I wanted some of the camera advances. $80 to buy specialised software for my $1800 camera (that also happens to be a phone) feels totally like the right thing to do.

Australian dollars/app-store pricing, and bought outright instead of subscribed.

Happy with what I paid there.

At the risk of feeding the trolls, no DSLR software comes close to the image manipulation of a modern phone. We know this with tools like MagicLantern that would have enabled this type of stuff.

To even equate these as being the same is being disengenious at best.

Honestly, as someone who is starting to go long-sighted, this is tempting me towards getting a 13 pro (or Pixel 6 i it is similarly good). I frequently find myself using my phone camera to zoom in on ridiculously small text on things, but my phone has always struggled with it. Good phone macro will be a feature I would use all the time.

I've heard of people who are very near-sighted using their smartphones to help them find their glasses. Just hold the phone close to your face, so you can see it in focus, and open the camera app. Voila, you can see the whole room in focus!

Never thought of that. Good idea

I have a phone with a macro lens. I have a mirrorless camera. As I told you, what matters for bokeh is the distance to the object and the diameter of the aperture. The iPhone needs computational bokeh because the aperture is 2.4mm wide, whereas one of my lenses has a 40mm aperture. That's why my camera produces more bokeh - the aperture has a wider diameter while the distance to the object is the same. That is litera…

You understand that cameras don't use a slit, right? Do you understand the optics in a modern camera? Further my 70mm lens has a smaller aperture than my 35mm f1.4 lens. Yet it has a much smaller depth of field for a given distance. Weird! Lens makers must not know your remarkable "slit lens" trick. At this point I'm convinced you are either trolling, or have dug so far into the depths of wrongness that you're dedica…

I think you are talking past each other, depth-of-field is dependent on the physical aperture not "F-Stops", which are often also called "aperture". Yes, afaik it's derived from single-element lenses but so are most other measures, and I'd be surprised if a real lens behaved different (at least in the center).

Your 35mm f/1.4 lens has a physical aperture of 35mm/1.4 = 25mm, so the equivalent 70mm lens with a 25mm aperture would have an F-stop of f/2.8. Hmm, can't think of many modern 70mm lenses besides Sigma's 70mm/2.8 macro which should have the same DoF, or if it's a standard zoom they should have equivalent DoF as well (unless it's Canon's f/2 zoom).

The (acceptable) depth-of-field is derived from blur-disk diameter, and the circle-of-confusion, for an object at a certain distance from subject ("point of focus") and relies only on physical aperture and distance to subject as stated (or alternatively, f-stop _and_ focal-length, because "phys. aperture = focal-length / f-stop").
