Xiaomi 15 Series

[dreamcast18]

Trump/US's unpredictable trade behaviour probably spooked if not strengthened the resolve of many to have a certain degree of self sufficiency or diversify chip supply chain

https://wccftech.com/xiaomi-forms-new-team-to-accelerate-in-house-chip-development/

As a side note Snapdragon Elite 3 will be on 2nm and (TSMC) warned of significant increase in fab cost. Time to pass cost to consumers... ( @dreamcast18 XM17 Ultra )

Small rice going the apple route! They do have the deep pockets to do so.

Will be interesting if they overtake Samsung as the global white appliance and mobile electronics leader.

Concur won't be 16U user unless it is a massive leapfrog. 17U hopefully is a good upgrade. As of now ..really happy with the 15U as an all rounder.

Am deciding what filters to bring for upcoming trip!

Long weekend bo liao, reproducing flare with my Olight torch, TPU casing removed..

1 inch sensor

The one inch sensor flare pattern, the "straighter" edge is where the light source is from.

* In this little experiment the flare shown above was neither attenuated nor enhanced when my cheapo TPU casing was reinstated.

* Roughly happened when light source approaches the edge of about 110-120 degree fov. Guesstimated based on my kid's school protractor ..

* The flare cannot be blocked if the 67mm rim were to be raised like a lens hood by about an inch. ( By the time a hood is tall enough for 1 inch sensor, the 14mm wide sensor would have vignetted++ esp at the non flash side. )

Of course angle of flare changes with position of light source.. in this case below taken not too long ago. From my little table top experiment this funky flare pattern would disappear if I angulate the camera ever slightly towards the light source and converting it slightly to a more veil or amorphous streak type flare.. but at spur of the moment it impractical la.

Ultrawide

The ultra wide at 14mm is almost free of such discrete flare patterns, the very most tiny barely perceptible blurred light streaks which might not be immediately visible in bright well exposed pictures.

HP9 Periscope

The flare at 100mm, likely the HP9 periscope sensor.
Not very sharply shaped except a hazy bluish loss of contrast/sharpness/details

Didn check for the 70mm floating tele which is also for macro since that angle of lighting is unlikely to manifest in macro shooting..

Take home -
Nothing to worry about.
Took me abit of time to reproduce the flare, it is uncommon and flares happen even with high end camera lenses, though we do hope manufacturers can at least make "beautiful" flares that can in a way value add compositions.

Flare from a modern Zeiss lens for digital sensors.

The issue with buying vivo in SG is lack of local retail support and global user base.

Waiting to see head to head 15U vs Vivo Ultra. Am sure Vivo has the edge...but the joy of using 15U for the last month is priceless.

Good analysis!

I recall my older days of using Lighwave 3D and creating digital lens flares to make the CGI look realistic ... Babylon 5 was the pioneer to recreate lens flares.

Alot to unpack but in broad strokes the automatic / photo mode acts like a "point and shoot".

It determines the parameters including iso and shutter speed according to the own way of metering. You can still use Xiaomi photo editor to apply filters and post processing.

However in certain occasions where you want the picture to pursue a particular direction where the automatic metering or settings may not be competent e g
- deliberate overexposure or underexposure
- high shutter speeds because subject is very fast

- low shutter speeds for long exposures
( But under Photo mode there are competent long exposures which is even easier to use )

Then enter the Pro mode. You can customize your fav shooting profiles down to setting contrast and saturation etc etc.

Also Pro mode allows for 50MP / 200MP / Raw / UltraRAW.

If you would like to learn , I suggest you could fiddle with Pro mode and play around with shutter speed and iso and white balance etc and see how each parameter affects the picture.

There is the photographic concept of the exposure triangle and in this case aperture is fixed, just need to know how iso/shutter speed affects outcome.

Thank you for your reply.. If I choose face metering but when there's no faces in the frame will the camera use auto metering?

based on the shape, i think 'straighter' flare could only from 100mm periscope

Ultrawide

i find it was easier to create flares deliberately with 13T ultrawide 15mm

was it easy to create flare like these?

Samsung has quite the global lead over XM.

XM, Oppo, Vivo collectively are a closer cluster.

Samsung probably has quite the margin, massive advantage also because Samsung Display makes their panels, Samsung Semiconductor makes memory isocell camera sensors etc. If they can get their act together with their troubled Exynos and 3mm foundry they could emerge even stronger.

Even if they strengthen photographic hardware , it only panders to enthusiastic folks like us, most of the consumers will not want to pay extra for that anyway.

Thank you for your reply.. If I choose face metering but when there's no faces in the frame will the camera use auto metering?

Probably. I must admit I am quite lazy and just leave it as such.

In backlited situations, the outcome will be a compromise unless you are aiming for artsy silhouetted subjects against a properly exposed background.

No matter the metering technique, the moment you expose the face well, u blow out the background exposure. HDR can help but might run the risk of looking fake. Even then it can still be overwhelmed if the dynamic range of the scene is too wide e.g background is just too bright.

Alternatively have abit of light / flash on the subject, or using reflectors but that might be abit too much for smartphones as cameras..

I typically try to reposition and avoid such scenes with too large a dynamic range since it does not play into your favor ( referring to my family members of course ) , I have seen someone use a diffused torchlight to try light the subject..

Can also try capture with Xiaomi Ultraraw and see if can salvage but that is alot of post processing work and I am unsure if can get better shot than the jpg after all the efforts...

It was more like it just happened, never really tried to replicate it.

But the newer prime lenses are getting harder and harder to get these veiled type flares, at least for the Sony GM lenses that I carry.

Yep - samsung owns end-2-end manufacturing.

XM is an outsourced model; if they start selling their PRC-only products globally..would be able to catch-up IMO. Their aircon, washer/dryer, fridge etc...would be very useful on my Google/XM Home app vs the current lean slate of cleaner robot/lights/doorlock/projector/airpurifier. Have quite a number of friends who switched from LG/Samsung TVs to the new-gen XM TVs. Foxconn clear winner here.

bottom line -> competition is good for innovation. my dollahs will go to whoever makes the best/good value stuff.

Bo liao long weekend table top experiment..

Reverse mounting a 50mm or wider lens on an existing lens traditionally creates a nifty high quality "macro filter" for DSLR/mirrorless setups.

So I have an unused Nikon 35mm f2 lying around...

Handheld reversing a 35mm f2.0, seems to only fit the HP9 sensor without zooming, the image circle is too small for the other sensors and barely sufficient for HP9.

HP9 sensor is larger than 1/1.4" vs the macro 1/2.51" sensor.

HP9 periscope sensor measures 11.7mm x 8.8mm

Without optical zooming , image measuring 12.5mm on an 11.7mm, we are almost reaching a 1:1 life size reproduction! ( 0.94x )
Very slight bits of chromatic aberrations at edges but otherwise sharp.

Optical zooming on the HP9 till the claimed 200mm gives a magnification of nearly 2:1 life size reproduction ( 1.95x ! )
Again chromatic aberrations. Shutter speed raised to compensate handshake...

Maximum magnification with XM Super Macro a piece of Calbee Hot & Spicy chips

Reverse mounting the 35/2 on HP9 periscope without optical zooming. This is near 1:1 magnification

Reverse mounting with optical zooming till 200mm. Depth of field is too razor thin ..

If XM can consider making a special macro adapter of a more reasonable size over the larger HP9, it might even outperform and easily out-magnify the smaller sensor 70mm floating macro.

* macro filters typically work better on telephotos than over wide lenses *

Cuktech cables have arrived

Worked like a charm on my ugreen GAN fast chargers.

Banding in Pro mode when you fixed certain higher shutter speeds under "profiles"

Be mindful of shooting under a prevailing or dominant artificial lighting conditions ( where the light strobes/flickers at 50hz/60hz etc ).

May not always occur but can happen.

Auto Antibanding / 50hz / 60hz will not work under these scenarios.

Slowing down shutter speeds can help but on the video liveview ? seems to suggest some degree of light banding can appear but might not the apparent in final photo.

Switching to allow Pro auto settings auto shutter or switch to Photo mode seems to help in my particular lighting setting.

* Banding tends to occur more often in unstacked sensors with slow read out speeds / rolling shutter.

* since modern smartphone sensors are more often than not stacked / high readout speed, this scenario is likely not as common.

Hi all, I just gotten my xiaomi 15 (regular). Any recommendations of a good protective casing like those of Ringke or Spigen quality?

Also noticed my TG is causing my FP to not work so well. Any recommendations for a good TG as well?

Many thanks in advance!

 

[asdyui31]

Anyone have recommendation for screen protector? Didn't use one, now already have small scratches

You put your phone where sia, so fast can get scratches

Tempered glass protector is not that good for ultrasonic sensors. Got to use film type

Pocket only. Just means screen not strong enough. Lucky is hairline scratch only not noticeable. Lol

Go look for those with custom cutters for flim type. Personally I always look for benny at marina sq https://www.hpinspiration.com.sg/11-screen-protectors
