Main Camera "2x Zoom" (digital enlargement)

This set of images is using the main camera but at "2x" digital zoom (enlargement). If you understand the technology, then the obvious result is that the focus distance should be the same, and the number of pixels used to portray 1mm of an image should be 2x, but since the lens and sensor have not changed, the detail and "optical resolution" should drop proportionally meaning one "gains nothing" by doing this. If this is not true, then something odd is happening.

I still have not had the time to do any calculations, and it might be a long time before I do. Moreover, when I do my work, I might not cover a calculation that you would like done. Put simply, I don't care. You have close enough to the same base images that I have to work from, and you can do your own math. If you do, then you can post your results and we'll all learn what you found out.

"Bokeh" is not really new to western photography, but we have adopted the Japanese term for it because it is faster than saying what it means in English which is "blurring due to shallow depth of field". Ok, I agree. Replacing about seven words with a single five letter word is worth it. Interestingly, I am not sure if the Xperia 10 iii had it in its original firmware. It might have, but if so, I did not get around to trying for quite a while. Ironically, I did not even try it until I was in a photographic situation where I felt it was needed. So I took a number of tried and kept the one I liked best. A few days later I tested it more formally with a pair of pictures of a telephone pole.

[Following paragraph added 2022-09020 10:00

In the Camera "information / Introduction to features" the following are lasted as "new" features: "QR Code reader", "Triple Camera", "Bokeh effect" and "Night Shot". But it does not say when they were "new". For example, I do not remember a time when "Triple camera" was not available. If it was there right from the first time I used the camera, what does that tell me about what they are calling "new"?]



The first three files are my telephone pole test pictures. The first picture "DSC_0001" used the Bokeh control while the "DSC_0002" was a "base case" showing the same composition without it. "DSC0001b" was my test to see where "out of focus" began. In fact, the telephone pole is blurred along its edge and maybe an inch or two nearer the camera. The "Yellow_0001a" picture used the "bokeh" control to blur out a distracting unattractive background.

As far as I can see, the function works well enough. I hope I do not start relying on it too much. I generally prefer a well composed background which integrates the main subject with it s surroundings.

Chrysanthemums, about 1 - 1.5 inch blossoms. Nothing special about this. The flowers looked nice.
Main lens, no "zoom", fairly close focus. I would not mind using this for a book cover. It would have to be waterproof ink on a durable paper.

[2022-10-04] I did not mention that the colours in this photo of the 'mums is very accurate to my eyes. I have really liked that aspect of all these recent flower pictures. I think gardeners who want to keep a record of their plants over the years would be quite happy with these. I have occasionally mentioned the higher models such as the recent Sony Xperia 5 iv. The reputation of these higher products are solid and one expects that they would do at least as well and perhaps better. Unfortunately, I have seen no real tests comparing them to these Xperia 10 models. For these particular flower pictures, I would be surprised if they could do that much better. They might have a sharpness edge, but the 10iii has been really good rendering the colours.

Xperia 10 iii "Night Mode" Samples

These were taken using the "Night Mode" selected from the camera "Mode" menu rather than from the "info" menu. I do not know if that makes a difference. The phone was mounted on a tripod.

I took these photos at "1x" and "2x" zoom levels but I did not check immediately if I had used the "main" and "tele" cameras. When I moved them to my computer I realized that the "2x" image was just the "main" camera digitally zoomed. I do not know if it is possible to use the "tele" camera with "night mode".

From what I am seeing, it might not make a difference. This version of "night mode" seems to be limited to raising the ISO very high (ISO 12,800). The exposure time of 1/15 sec is disappointingly quick. The processing seems to be ordinary. Comparing the streetlights to the tree foliage, the contrast looks like what I see in typical dark scene photos.

I should try again to see if I can use the "tele" camera in "Night Mode", but since the results are not really impressive, I probably will not bother testing again in the near future.

[2022-10-04] Objects of Interest: the light spot at around 403,120 is probably the moon the very small one at around 260,740 is probably a helicopter, and the one at around 1282,624 is an aircraft. I could see the latter one moving, so it was not very far -- possibly near the shore of Lake Ontario.

Night Mode Re-test

I decided to try the "Night Mode" again, and this time to directly compare it to a normal mode photo. I am much more impressed with the results, now that I have a more direct comparison.

The baseline picture is the "001" version and the "Night Mode" picture is the "010" version. Unfortunately, the compositions are not quite identical (the "normal" picture was aimed a bit more to the right than I intended, but the compositions are close enough that the stats are reasonably comparable.

The "Night Mode" caught a couple of "astro" objects. I think one was a star but I think the other was a satellite. I could have checked that using SkyView, but I did not think of that. "Night Mode" also brought up some sky color, a few clouds and low-level condensation over the lake.

Sadly, this camera, in general, lacks sharpness. I think the Xperia 5iv might be sharper, but I have seen no tests that confirm that.

For a detail crop I tried to include some trees. I know they are trees because I have walked under them. From the pictures, I think most people would recognize them as trees, but one certainly cannot identify individual leaves.

I tried "4x zoom" and it did not use the "tele" camera. It just digitally magnified the main camera 4x. I am not bothering to post the results.

I would be interested in finding out how much better a job the Xperia 5iv would do.

[2022-10-03 20:35

I can add that Night Mode has a considerable processing time penalty. I did not time it precisely but I think that each photo took about 5 sec. or more. So that would indicate that a lot was being done. I have heard "Night Mode" described for other phones as a composited image from a number of shots. It does seem likely that this sort of thing was being done on this phone.]
