Can't you use Xrandr or something to just double up on pixels or use what they called integer scaling in other OS to avoid interpolation?


Anything other than 1:1 is interpolation, which means creating or destroying pixels that weren't present in the original image. Whether it involves fractions or not, only affects the quality of these non-existing pixels. But the best approach is to avoid interpolation alltogether. Interpolation always gives you a distorted view of noise or film grain (it's actually even worse with grain because it happens twice: once in a scanner and then again on your monitor).

To evaluate images, you should be viewing them at 100% at native display resolution, ideally as close as possible to the target printing PPI.

Technically true, but in reality it is usually just about impossible to see differences between interpolated and non-interpolated images, Evan at 100% magnification.

Another caution: comparing 100% magnification crops from sources with different pixel resolution (and/or formats) is a fraught exercise that can mislead.

You're right when you're downsampling. But he's suggesting to interpolate up to 200% to complain about rough noise pattern.

The body design is quite identical to A7R5 or 4th gen which is very very disappointing. No ergonomic upgrades while no custom button on the front side. A huge downgrade from 5th gen or A9iii/A1ii. The battery grip sucks too.


Yeah there will have to be yet another grip released when Sony refreshes the a1 or a9 line.

Many people will disagree with me including my past self, but I now think a9 as the sports / journalism line could benefit from a switch to integrated grip bodies. These cameras are being used vertically half - if not more - of the time, and what's good about integrated grips is that they balance with the lens much better than extension grips: every one of the latter is too far away from the lens mount.

I suspect it will still scan the whole sensor when in APS-C mode, as usually the whole image is still captured and the crop can be undone in post.

It's definitely your high-DPI display. It obscures both noise and detail issues.



Sounds like you have never used a Retina display.

A high ppi display (218+ppi) shows text with completely smooth outlines and no pixelation is visible at normal viewing distances. Individual pixels are not discernible by the human eye at normal viewing distances - that's the whole point.

A low resolution display on the other have can never show completely smooth text or images no matter how good they are because the display pixels are visible to the naked eye.

A low resolution display will ruin your images no matter how good they are. On the other hand a Retina display will make a good image stand out a mile from a poor image but it won't magically repair noise or lack of detail - the lack of detail will be more obvious with a smeared painted look.

Do yourself a favour and compare a good A7r5 image on a 5K 27inch display side by side with a 4K 27inch display. The difference is immediately obvious - it's like night and day.

Noise is noise, high ppi displays don't magically make noise disappear and your eyes don't apply noise reduction nor does the display.

Noise will affect the sharpness of the detail just as much - in fact more so than on a low res display - where you can't see the detail clearly no matter the image quality because of the pixelation resulting from the display pixels.

All you have to do is compare the text or an image on a 5k 27inch display to the same text or image on a 4K 27 inch display.

A hair in an image is like the edges of text. You just can't get a fine straight hair on that 4K display because you can see the pixelation of the display so the hair has slightly jagged edges no matter the resolution or quality of the image itself. If you stand back far enough it may look better but because you are further away you can't make out the same level of detail anymore.

A noisy image on the 5K display will look have that painted or smeared look about it and it will be hard to make out individual feathers edges or hairs.

Yes, I suspect that too, but it is the time to scan the part of the image you are using that determines movement distortion. So, if you crop and are using a smaller part of the image, or even if your subject takes up a smaller part of the frame, then you will get less movement distortion. We will see some shots before too long with fast moving subjects (e.g., a hummingbird) with no movement distortion, but that will be a heavily cropped image and the subject will be from a small part of the frame. At a 4X crop the sensor scan speed will be less than 5ms and that is faster than the Sony A9/A9II and nearly as fast as the A1/A1 II. On this camera that will be about a 4 MP image and some will find that useful for things like posting to the web, but it is also obviously limited in a lot of ways (noise, depth of field, dynamic range).

Yes, I see what you mean. The scan of the relevant (cropped) portion will take less time than the whole, although it might still be dependent on the scan pattern, e.g. if it leaves and returns to the cropped section multiple times. Hopefully we'll see some good real world examples very soon!

That's fine for ordinary viewing to have a pretty image. My point is that I want to see at pixel level to assess the image carefully, especially from a new camera. It's like when you are viewing a waveform from a sensor stream capture you zoom in to see the shape more exactly, or when checking an XRPD pattern, chromatogram, etc. Many types of data can be oversampled, but sometimes you want to examine data closer to sampling level. I'd need to view at 10-12" which is not feasible at my age.

Exactly. It's the limits of our vision which make high DPI displays unsuitable for evaluating noise and detail. Obviously high PPI displays don't physically reduce detail or noise but if our perception of them is reduced then the effect is the same. Failing to consider this in any discussion about high PPI displays is like quoting the G forces a fighter jet can withstand before breaking up without consideration for how the pilot would pass out well before that.

I’ve sold all but my 35mm GM lenses and haven’t used my Loxia lenses, because of the poor focusing experience on the A7CR. For me, the responsiveness of the camera in general and the improvements in the EVF, along with the ability to store a number of presets resulted in an early pre-order. I expect a pleasant manual focus experience and given that my wife will mostly use the camera, having descriptive presets will greatly improve her experience. She isn’t interested in learning about photography, but she actually has a pretty good eye with regards to composition. Her single use case for using a camera is travel and the presets with the 24-50mm /f2.8 lens permanently mounted will really help out. An APSc mode preset on a 67Mpix camera will go a long way towards providing a 75mm 28Mpix option. Additionally, she regularly uses her iPhone for video and the video capabilities and the presets present a compelling alternative to her iPhone.

Actually, at high enough resolutions they do (sort of) make the noise disappear, since we are no longer able to really see the individual “noise grains” and instead essentially average them.

Imagine a 5000 ppi display with noise variations in the luminosity of the pixels. You cannot actually see individual pixels at such high (imaginary) densities, so your vision would, indeed, average them. To some extent this happens with current high resolution monitors.

For those of use who have. been doing photography for a long time, it is kind of like fine grain versus larger grain film. There is “grain noise” in both of them, but the smaller grain size of the fine grain film makes the noise less visible.

Also, interpolation tends to average out noise differences to some extent.

- - -

This is relevant to the discussion of the value of viewing images at higher than 100% magnification in post. If we are, for example, trying to optimize sharpening we can more clearly see the effect of (and the need for adjustments of) sharpening settings at the high magnifications, even though the images will typically be viewed at lower magnifications.

I do agree that complaining about “problems” that are only visible at sizes/magnifications that are higher than you’ll ever use is pretty pointless. At some level of magnification EVERY image has “problems.”

Related: For the “don’t interpolate” people, there’s the “problem” of the non-interpolated image using a different resolution than the printer or the screen when the image is displayed. What if you don’t interpolate but leave your image at, say 527ppi… and send it to a printer at 1440 or 2889 dpi? Guess what… the PRINTER interpolates it! And if you display your interpolated image on a monitor with some specific ppi… it gets interpolated by the monitor! :-)

"Sony is praised for its dominant sensor innovation and significant performance leaps in cameras like the a7R VI [32:48], Canon and Nikon are criticized for failing to push resolution boundaries [31:01] and introducing overly confusing, compromised product lineups [36:58]."

@snapsy@, help me out here. I am not a techie and I have no engineering background, so what I am saying here may just reflect my ignorance.

But I feel that something is missing from the discussion of sensor speed and crop factor. The reason the sensor readout speed seems shorter is because the area scanned is smaller--but the rate of scanning stays the same. So, for example, LED banding would occur as badly with a crop image as with a full-frame image, because the rate was the same even though the total time spent scanning was shorter. Similarly for rolling shutter effects: the same subject motion will cover a larger percentage of area on a crop image than it would on a full-frame image--so the degree of rolling shutter would be proportional to the area/movement and thus the same.

What am I missing?

A 5000ppi display is not analogous to a 218 ppi display. A 5000ppi display would result in blocks of 20x20 or greater pixels being seen as individual pixels - in effect downsampling the image by a huge amount. All pixel size fine details, such as hair would disappear.

Never mind that the entire 10k A7r5 image would be around 2 inches wide on this imaginary 5000ppi display of yours when viewed at 100%.

Remember with retina we are talking individual pixels not being discernible from each other - we are not talking about them not being visible. They are just small enough so that sharp rounded edges such as is found on text looks completely smooth to the naked eye - as if drawn by an ink pen with a smooth stroke rather than a dot matrix printer.
