Smartphones for macro photography

Digital cameras are starting to die out.
Everything is very similar to how film cameras died out 15-20 years ago.
Small digital soap boxes are practically no longer needed by anyone...
People are switching to smartphones en masse.
The camera of a modern smartphone is quite enough for photographing biotopes,
and some smartphone models have macro lenses.

I also got a smartphone with
a Xiaomi Redmi Note 9S macro lens (my wife gave it to me on Defender of the Fatherland Day).
And, of course, I tried it for macro photography ; -)
- - -
The main lens of the Redmi Note 9s
can produce frames either at 12 Mpx,
or in the " Pro " mode-at 48 Mpx (8000 x 6000).
And the macro lens is weak - only 5 Megapixels (2592 x 1944).

Here's what a macro lens can do (beetle length = 3 cm, beetle distance ~2.5 cm):

For comparison, I will take a picture from the main lens at 48 Mpx
(up to the beetle ~10 cm) at the minimum focusing distance.

And crop this image at 48 Mpx.

The pictures are of course super as for smarts, especially since the smart is always with you, and there are such cases that some bug is sitting on the wall of the store)) BUT, there is a nuance, I would like to see macro photos with such a smartphone in nature! The distance of 2.5 cm to the beetle in natural conditions, and that the beetle endured it, and to get through all sorts of plants and stones-this is from the area of exceptional cases.
I'm not talking about the os

, even a lazy and oak leaf will fly away at such distances) Cryptoheilus will fly away even at the moment when the smart will get out of the pant leg

Unfortunately, manufacturers do not do in their macro projects for smart what is needed for shooting in nature-an extended distance while maintaining the scale

Shit Pan wrote, as usual. Different macros are needed, different macros are important-depending on the situation with the EFR from 30 mm and up to... And the fact that Pan can only take pictures of insects with an EFR under 200 mm is his purely personal problem. Short-focus lenses have two big advantages: first, they allow you to shoot with your hands at longer exposures, and second, with a small shooting distance, the edge of the frame is fashionable to rest on the substrate on which the insect is sitting or in the hand holding the plant on which it is sitting. This reduces the wiggle room (which, by the way, affects three-quarters of panov Shidevrov on any enemy sites) to almost zero.

Now about the OS. Indeed, there are such cowardly wasps that already fly away for two meters, but they are a minority. The same polysts on flowers, as a rule, can be safely photographed, as long as the lens is not reproached with a wasp. The same applies to most small fry, which Pan doesn't seem to notice at all, since there are almost no small wasp and bee species among his shiders. And for all this small stuff, short-focus lenses are much preferable.

Thank you for the interesting reading. What tricks do not go smradphone manufacturers to compensate for the tiny size of the matrices! Some kind of artificial blurring was invented with the help of neural

networks. Fortunately, this is not necessary in macro photography, but it is completely unnecessary. But you definitely shouldn't shoot portraits on a smudphone, even if it has at least 10 cameras.

This lynza on a clothespin is absolutely necessary to throw out, it spoils the energy of the apartment

And yes, without being able to control the ISO manually, you can only shoot macro shots in very bright light. Here, the ISO clearly flew into the sky and the terrible shmodawing ruined everything.

I'll be even more brief: maybe! But only if there is a G. lens on the DSLR, or it is in the hands of H. fotogrof. In fact, smartphones have the same advantages as digital cameras: lenses with a large focal range are included (in some models). They behave especially well on a wide angle (in many cases it is the only one) - the quality is quite comparable to the same vaunted flexogons on APS-C.

As for the macro, the example of Bomki alas. as here one svidolmyy pan often expresses, not uh-huh. It is especially noticeable in the drops. But this is the lens ' fault. With the usual high-quality lens (such as those that stand on smartphones and galaxies) and a high-quality macro attachment, the result will be much better.
Well, if you are shooting a birthmark on it, then probably yes, but if there is a lens and a matrix, then this is not so clear. because a small lens and a small matrix can be made using other, much more advanced technologies than a large lens and a large matrix for a comparable price. The bonus is a large GRP at large apertures (and this more than compensates for the poor high ISO and low diffraction threshold). But this is clearly not the case for a Bomka with a lens. There would be a good lens from the microscope fit. But, probably, it can not be installed without confusing the brains of the gadget.

But really doomed to an early almost complete extinction, so it is precisely digital mirrors. Of course, smradfony them too crowded, but only in the hands of glamorous fif. In the hands of photographers, mirrorless cameras crowd them. A big advantage of their latest models is a fully electronic shutter=rate of fire+noiselessness+eternal life. Of course, you can also put this one in a DSLR, view live view, add EVIE, throw out the mirror, but oh, this will turn out to be a mirrorless one

And how are these different pixels for different objects? do they change along with the matrix?

a pinhole camera is an optical principle for constructing images. one of the laws of physics that cannot be circumvented. the smaller its size, the less light falls on the matrix. and it is he who draws, my dear. light. hence the name-photo (light) graph (pis).

Mmmdaa, what a mess you've made here, dear...
Well, come on, it's a matter of everyday life, cute scolding, just amused)
I'm here for what reason, I updated myself another kitayphone, this time I took a Xiaomi Redmi laptop 10 pro, the supermacro mode was very pleasantly hidden in the camera settings...quite a passable quality, of course there are difficulties with the focus, but in general, the norms.

How cute are they? Then a fat troll came along. and moderators don't catch mice.

The photos are quite good, although in some places the grain is very unpleasant, it seems that the ISO is picking up. But what is good about Android - you can install a third-party camera module with such post-processing as your heart desires (although without it at all - with RAW output). The main thing is that the optics pulls such a scale.

I now have an ancient ancestor of your ketyphone, Redmi 3s, so there is MDF 15 centimeters, despite the fact that the angle is very wide - the scale turns out to be no. But the sharpness is not bad, so if there is an urgent need to capture something not very small in the absence of a normal camera at hand, then you can use it.
